NAME
hgrc - configuration files for Mercurial
DESCRIPTION
The Mercurial system uses a set of configuration files to control
aspects of its behavior.
TROUBLESHOOTING
If you're having problems with your configuration, hg config --debug
can help you understand what is introducing a setting into your envi-
ronment.
See hg help config.syntax and hg help config.files for information
about how and where to override things.
STRUCTURE
The configuration files use a simple ini-file format. A configuration
file consists of sections, led by a [section] header and followed by
name = value entries:
[ui]
username = Firstname Lastname <firstname.lastname@example.net>
verbose = True
The above entries will be referred to as ui.username and ui.verbose,
respectively. See hg help config.syntax.
FILES
Mercurial reads configuration data from several files, if they exist.
These files do not exist by default and you will have to create the
appropriate configuration files yourself:
Local configuration is put into the per-repository <repo>/.hg/hgrc
file.
Global configuration like the username setting is typically put into:
o $HOME/.hgrc (on Unix, Plan9)
The names of these files depend on the system on which Mercurial is
installed. *.rc files from a single directory are read in alphabetical
order, later ones overriding earlier ones. Where multiple paths are
given below, settings from earlier paths override later ones.
The following files are consulted:
o <repo>/.hg/hgrc (per-repository)
o $HOME/.hgrc (per-user)
o ${XDG_CONFIG_HOME:-$HOME/.config}/hg/hgrc (per-user)
o <install-root>/etc/mercurial/hgrc (per-installation)
o <install-root>/etc/mercurial/hgrc.d/*.rc (per-installation)
o /etc/mercurial/hgrc (per-system)
o /etc/mercurial/hgrc.d/*.rc (per-system)
o <internal>/default.d/*.rc (defaults)
Per-repository configuration options only apply in a particular reposi-
tory. This file is not version-controlled, and will not get transferred
during a "clone" operation. Options in this file override options in
all other configuration files.
On Unix, most of this file will be ignored if it doesn't belong to a
trusted user or to a trusted group. See hg help config.trusted for more
details.
Per-user configuration file(s) are for the user running Mercurial.
Options in these files apply to all Mercurial commands executed by this
user in any directory. Options in these files override per-system and
per-installation options.
Per-installation configuration files are searched for in the directory
where Mercurial is installed. <install-root> is the parent directory of
the hg executable (or symlink) being run.
For example, if installed in /shared/tools/bin/hg, Mercurial will look
in /shared/tools/etc/mercurial/hgrc. Options in these files apply to
all Mercurial commands executed by any user in any directory.
Per-installation configuration files are for the system on which Mercu-
rial is running. Options in these files apply to all Mercurial commands
executed by any user in any directory. Mercurial checks each of these
locations in the specified order until one or more configuration files
are detected.
Per-system configuration files are for the system on which Mercurial is
running. Options in these files apply to all Mercurial commands exe-
cuted by any user in any directory. Options in these files override
per-installation options.
Mercurial comes with some default configuration. The default configura-
tion files are installed with Mercurial and will be overwritten on
upgrades. Default configuration files should never be edited by users
or administrators but can be overridden in other configuration files.
So far the directory only contains merge tool configuration but pack-
agers can also put other default configuration there.
SYNTAX
A configuration file consists of sections, led by a [section] header
and followed by name = value entries (sometimes called configuration
keys):
[spam]
eggs=ham
green=
eggs
Each line contains one entry. If the lines that follow are indented,
they are treated as continuations of that entry. Leading whitespace is
removed from values. Empty lines are skipped. Lines beginning with # or
; are ignored and may be used to provide comments.
Configuration keys can be set multiple times, in which case Mercurial
will use the value that was configured last. As an example:
[spam]
eggs=large
ham=serrano
eggs=small
This would set the configuration key named eggs to small.
It is also possible to define a section multiple times. A section can
be redefined on the same and/or on different configuration files. For
example:
[foo]
eggs=large
ham=serrano
eggs=small
[bar]
eggs=ham
green=
eggs
[foo]
ham=prosciutto
eggs=medium
bread=toasted
This would set the eggs, ham, and bread configuration keys of the foo
section to medium, prosciutto, and toasted, respectively. As you can
see there only thing that matters is the last value that was set for
each of the configuration keys.
If a configuration key is set multiple times in different configuration
files the final value will depend on the order in which the different
configuration files are read, with settings from earlier paths overrid-
ing later ones as described on the Files section above.
A line of the form %include file will include file into the current
configuration file. The inclusion is recursive, which means that
included files can include other files. Filenames are relative to the
configuration file in which the %include directive is found. Environ-
ment variables and ~user constructs are expanded in file. This lets you
do something like:
%include ~/.hgrc.d/$HOST.rc
to include a different configuration file on each computer you use.
A line with %unset name will remove name from the current section, if
it has been set previously.
The values are either free-form text strings, lists of text strings, or
Boolean values. Boolean values can be set to true using any of "1",
"yes", "true", or "on" and to false using "0", "no", "false", or "off"
(all case insensitive).
List values are separated by whitespace or comma, except when values
are placed in double quotation marks:
allow_read = "John Doe, PhD", brian, betty
Quotation marks can be escaped by prefixing them with a backslash. Only
quotation marks at the beginning of a word is counted as a quotation
(e.g., foo"bar baz is the list of foo"bar and baz).
SECTIONS
This section describes the different sections that may appear in a Mer-
curial configuration file, the purpose of each section, its possible
keys, and their possible values.
alias
Defines command aliases.
Aliases allow you to define your own commands in terms of other com-
mands (or aliases), optionally including arguments. Positional argu-
ments in the form of $1, $2, etc. in the alias definition are expanded
by Mercurial before execution. Positional arguments not already used by
$N in the definition are put at the end of the command to be executed.
Alias definitions consist of lines of the form:
<alias> = <command> [<argument>]...
For example, this definition:
latest = log --limit 5
creates a new command latest that shows only the five most recent
changesets. You can define subsequent aliases using earlier ones:
stable5 = latest -b stable
Note It is possible to create aliases with the same names as existing
commands, which will then override the original definitions.
This is almost always a bad idea!
An alias can start with an exclamation point (!) to make it a shell
alias. A shell alias is executed with the shell and will let you run
arbitrary commands. As an example,
echo = !echo $@
will let you do hg echo foo to have foo printed in your terminal. A
better example might be:
purge = !$HG status --no-status --unknown -0 re: | xargs -0 rm -f
which will make hg purge delete all unknown files in the repository in
the same manner as the purge extension.
Positional arguments like $1, $2, etc. in the alias definition expand
to the command arguments. Unmatched arguments are removed. $0 expands
to the alias name and $@ expands to all arguments separated by a space.
"$@" (with quotes) expands to all arguments quoted individually and
separated by a space. These expansions happen before the command is
passed to the shell.
Shell aliases are executed in an environment where $HG expands to the
path of the Mercurial that was used to execute the alias. This is use-
ful when you want to call further Mercurial commands in a shell alias,
as was done above for the purge alias. In addition, $HG_ARGS expands to
the arguments given to Mercurial. In the hg echo foo call above,
$HG_ARGS would expand to echo foo.
Note Some global configuration options such as -R are processed
before shell aliases and will thus not be passed to aliases.
annotate
Settings used when displaying file annotations. All values are Booleans
and default to False. See hg help config.diff for related options for
the diff command.
ignorews
Ignore white space when comparing lines.
ignorewseol
Ignore white space at the end of a line when comparing lines.
ignorewsamount
Ignore changes in the amount of white space.
ignoreblanklines
Ignore changes whose lines are all blank.
auth
Authentication credentials and other authentication-like configuration
for HTTP connections. This section allows you to store usernames and
passwords for use when logging into HTTP servers. See hg help con-
fig.web if you want to configure who can login to your HTTP server.
The following options apply to all hosts.
cookiefile
Path to a file containing HTTP cookie lines. Cookies matching a
host will be sent automatically.
The file format uses the Mozilla cookies.txt format, which
defines cookies on their own lines. Each line contains 7 fields
delimited by the tab character (domain, is_domain_cookie, path,
is_secure, expires, name, value). For more info, do an Internet
search for "Netscape cookies.txt format."
Note: the cookies parser does not handle port numbers on
domains. You will need to remove ports from the domain for the
cookie to be recognized. This could result in a cookie being
disclosed to an unwanted server.
The cookies file is read-only.
Other options in this section are grouped by name and have the follow-
ing format:
<name>.<argument> = <value>
where <name> is used to group arguments into authentication entries.
Example:
foo.prefix = hg.intevation.de/mercurial
foo.username = foo
foo.password = bar
foo.schemes = http https
bar.prefix = secure.example.org
bar.key = path/to/file.key
bar.cert = path/to/file.cert
bar.schemes = https
Supported arguments:
prefix
Either * or a URI prefix with or without the scheme part. The
authentication entry with the longest matching prefix is used
(where * matches everything and counts as a match of length 1).
If the prefix doesn't include a scheme, the match is performed
against the URI with its scheme stripped as well, and the
schemes argument, q.v., is then subsequently consulted.
username
Optional. Username to authenticate with. If not given, and the
remote site requires basic or digest authentication, the user
will be prompted for it. Environment variables are expanded in
the username letting you do foo.username = $USER. If the URI
includes a username, only [auth] entries with a matching user-
name or without a username will be considered.
password
Optional. Password to authenticate with. If not given, and the
remote site requires basic or digest authentication, the user
will be prompted for it.
key
Optional. PEM encoded client certificate key file. Environment
variables are expanded in the filename.
cert
Optional. PEM encoded client certificate chain file. Environment
variables are expanded in the filename.
schemes
Optional. Space separated list of URI schemes to use this
authentication entry with. Only used if the prefix doesn't
include a scheme. Supported schemes are http and https. They
will match static-http and static-https respectively, as well.
(default: https)
If no suitable authentication entry is found, the user is prompted for
credentials as usual if required by the remote.
color
Configure the Mercurial color mode. For details about how to define
your custom effect and style see hg help color.
mode
String: control the method used to output color. One of auto,
ansi, win32, terminfo or debug. In auto mode, Mercurial will use
ANSI mode by default (or win32 mode prior to Windows 10) if it
detects a terminal. Any invalid value will disable color.
pagermode
String: optional override of color.mode used with pager.
On some systems, terminfo mode may cause problems when using
color with less -R as a pager program. less with the -R option
will only display ECMA-48 color codes, and terminfo mode may
sometimes emit codes that less doesn't understand. You can work
around this by either using ansi mode (or auto mode), or by
using less -r (which will pass through all terminal control
codes, not just color control codes).
On some systems (such as MSYS in Windows), the terminal may sup-
port a different color mode than the pager program.
commands
commit.post-status
Show status of files in the working directory after successful
commit. (default: False)
resolve.confirm
Confirm before performing action if no filename is passed.
(default: False)
resolve.explicit-re-merge
Require uses of hg resolve to specify which action it should
perform, instead of re-merging files by default. (default:
False)
resolve.mark-check
Determines what level of checking hg resolve --mark will perform
before marking files as resolved. Valid values are none`,
``warn, and abort. warn will output a warning listing the
file(s) that still have conflict markers in them, but will still
mark everything resolved. abort will output the same warning
but will not mark things as resolved. If --all is passed and
this is set to abort, only a warning will be shown (an error
will not be raised). (default: none)
status.relative
Make paths in hg status output relative to the current direc-
tory. (default: False)
status.terse
Default value for the --terse flag, which condenses status out-
put. (default: empty)
update.check
Determines what level of checking hg update will perform before
moving to a destination revision. Valid values are abort, none,
linear, and noconflict. abort always fails if the working direc-
tory has uncommitted changes. none performs no checking, and may
result in a merge with uncommitted changes. linear allows any
update as long as it follows a straight line in the revision
history, and may trigger a merge with uncommitted changes.
noconflict will allow any update which would not trigger a merge
with uncommitted changes, if any are present. (default: linear)
update.requiredest
Require that the user pass a destination when running hg update.
For example, hg update .:: will be allowed, but a plain hg
update will be disallowed. (default: False)
committemplate
changeset
String: configuration in this section is used as the template to
customize the text shown in the editor when committing.
In addition to pre-defined template keywords, commit log specific one
below can be used for customization:
extramsg
String: Extra message (typically 'Leave message empty to abort
commit.'). This may be changed by some commands or extensions.
For example, the template configuration below shows as same text as one
shown by default:
[committemplate]
changeset = {desc}\n\n
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: {extramsg}
HG: --
HG: user: {author}\n{ifeq(p2rev, "-1", "",
"HG: branch merge\n")
}HG: branch '{branch}'\n{if(activebookmark,
"HG: bookmark '{activebookmark}'\n") }{subrepos %
"HG: subrepo {subrepo}\n" }{file_adds %
"HG: added {file}\n" }{file_mods %
"HG: changed {file}\n" }{file_dels %
"HG: removed {file}\n" }{if(files, "",
"HG: no files changed\n")}
diff()
String: show the diff (see hg help templates for detail)
Sometimes it is helpful to show the diff of the changeset in the editor
without having to prefix 'HG: ' to each line so that highlighting works
correctly. For this, Mercurial provides a special string which will
ignore everything below it:
HG: ------------------------ >8 ------------------------
For example, the template configuration below will show the diff below
the extra message:
[committemplate]
changeset = {desc}\n\n
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: {extramsg}
HG: ------------------------ >8 ------------------------
HG: Do not touch the line above.
HG: Everything below will be removed.
{diff()}
Note For some problematic encodings (see hg help win32mbcs for
detail), this customization should be configured carefully, to
avoid showing broken characters.
For example, if a multibyte character ending with backslash
(0x5c) is followed by the ASCII character 'n' in the customized
template, the sequence of backslash and 'n' is treated as
line-feed unexpectedly (and the multibyte character is broken,
too).
Customized template is used for commands below (--edit may be
required):
o hg backout
o hg commit
o hg fetch (for merge commit only)
o hg graft
o hg histedit
o hg import
o hg qfold, hg qnew and hg qrefresh
o hg rebase
o hg shelve
o hg sign
o hg tag
o hg transplant
Configuring items below instead of changeset allows showing customized
message only for specific actions, or showing different messages for
each action.
o changeset.backout for hg backout
o changeset.commit.amend.merge for hg commit --amend on merges
o changeset.commit.amend.normal for hg commit --amend on other
o changeset.commit.normal.merge for hg commit on merges
o changeset.commit.normal.normal for hg commit on other
o changeset.fetch for hg fetch (impling merge commit)
o changeset.gpg.sign for hg sign
o changeset.graft for hg graft
o changeset.histedit.edit for edit of hg histedit
o changeset.histedit.fold for fold of hg histedit
o changeset.histedit.mess for mess of hg histedit
o changeset.histedit.pick for pick of hg histedit
o changeset.import.bypass for hg import --bypass
o changeset.import.normal.merge for hg import on merges
o changeset.import.normal.normal for hg import on other
o changeset.mq.qnew for hg qnew
o changeset.mq.qfold for hg qfold
o changeset.mq.qrefresh for hg qrefresh
o changeset.rebase.collapse for hg rebase --collapse
o changeset.rebase.merge for hg rebase on merges
o changeset.rebase.normal for hg rebase on other
o changeset.shelve.shelve for hg shelve
o changeset.tag.add for hg tag without --remove
o changeset.tag.remove for hg tag --remove
o changeset.transplant.merge for hg transplant on merges
o changeset.transplant.normal for hg transplant on other
These dot-separated lists of names are treated as hierarchical ones.
For example, changeset.tag.remove customizes the commit message only
for hg tag --remove, but changeset.tag customizes the commit message
for hg tag regardless of --remove option.
When the external editor is invoked for a commit, the corresponding
dot-separated list of names without the changeset. prefix (e.g. com-
mit.normal.normal) is in the HGEDITFORM environment variable.
In this section, items other than changeset can be referred from oth-
ers. For example, the configuration to list committed files up below
can be referred as {listupfiles}:
[committemplate]
listupfiles = {file_adds %
"HG: added {file}\n" }{file_mods %
"HG: changed {file}\n" }{file_dels %
"HG: removed {file}\n" }{if(files, "",
"HG: no files changed\n")}
decode/encode
Filters for transforming files on checkout/checkin. This would typi-
cally be used for newline processing or other localization/canonical-
ization of files.
Filters consist of a filter pattern followed by a filter command. Fil-
ter patterns are globs by default, rooted at the repository root. For
example, to match any file ending in .txt in the root directory only,
use the pattern *.txt. To match any file ending in .c anywhere in the
repository, use the pattern **.c. For each file only the first match-
ing filter applies.
The filter command can start with a specifier, either pipe: or temp-
file:. If no specifier is given, pipe: is used by default.
A pipe: command must accept data on stdin and return the transformed
data on stdout.
Pipe example:
[encode]
# uncompress gzip files on checkin to improve delta compression
# note: not necessarily a good idea, just an example
*.gz = pipe: gunzip
[decode]
# recompress gzip files when writing them to the working dir (we
# can safely omit "pipe:", because it's the default)
*.gz = gzip
A tempfile: command is a template. The string INFILE is replaced with
the name of a temporary file that contains the data to be filtered by
the command. The string OUTFILE is replaced with the name of an empty
temporary file, where the filtered data must be written by the command.
This filter mechanism is used internally by the eol extension to trans-
late line ending characters between Windows (CRLF) and Unix (LF) for-
mat. We suggest you use the eol extension for convenience.
defaults
(defaults are deprecated. Don't use them. Use aliases instead.)
Use the [defaults] section to define command defaults, i.e. the default
options/arguments to pass to the specified commands.
The following example makes hg log run in verbose mode, and hg status
show only the modified files, by default:
[defaults]
log = -v
status = -m
The actual commands, instead of their aliases, must be used when defin-
ing command defaults. The command defaults will also be applied to the
aliases of the commands defined.
diff
Settings used when displaying diffs. Everything except for unified is a
Boolean and defaults to False. See hg help config.annotate for related
options for the annotate command.
git
Use git extended diff format.
nobinary
Omit git binary patches.
nodates
Don't include dates in diff headers.
noprefix
Omit 'a/' and 'b/' prefixes from filenames. Ignored in plain
mode.
showfunc
Show which function each change is in.
ignorews
Ignore white space when comparing lines.
ignorewsamount
Ignore changes in the amount of white space.
ignoreblanklines
Ignore changes whose lines are all blank.
unified
Number of lines of context to show.
word-diff
Highlight changed words.
email
Settings for extensions that send email messages.
from
Optional. Email address to use in "From" header and SMTP enve-
lope of outgoing messages.
to
Optional. Comma-separated list of recipients' email addresses.
cc
Optional. Comma-separated list of carbon copy recipients' email
addresses.
bcc
Optional. Comma-separated list of blind carbon copy recipients'
email addresses.
method
Optional. Method to use to send email messages. If value is smtp
(default), use SMTP (see the [smtp] section for configuration).
Otherwise, use as name of program to run that acts like sendmail
(takes -f option for sender, list of recipients on command line,
message on stdin). Normally, setting this to sendmail or
/usr/sbin/sendmail is enough to use sendmail to send messages.
charsets
Optional. Comma-separated list of character sets considered con-
venient for recipients. Addresses, headers, and parts not con-
taining patches of outgoing messages will be encoded in the
first character set to which conversion from local encoding
($HGENCODING, ui.fallbackencoding) succeeds. If correct conver-
sion fails, the text in question is sent as is. (default: '')
Order of outgoing email character sets:
1. us-ascii: always first, regardless of settings
2. email.charsets: in order given by user
3. ui.fallbackencoding: if not in email.charsets
4. $HGENCODING: if not in email.charsets
5. utf-8: always last, regardless of settings
Email example:
[email]
from = Joseph User <joe.user@example.com>
method = /usr/sbin/sendmail
# charsets for western Europeans
# us-ascii, utf-8 omitted, as they are tried first and last
charsets = iso-8859-1, iso-8859-15, windows-1252
extensions
Mercurial has an extension mechanism for adding new features. To enable
an extension, create an entry for it in this section.
If you know that the extension is already in Python's search path, you
can give the name of the module, followed by =, with nothing after the
=.
Otherwise, give a name that you choose, followed by =, followed by the
path to the .py file (including the file name extension) that defines
the extension.
To explicitly disable an extension that is enabled in an hgrc of
broader scope, prepend its path with !, as in foo = !/ext/path or foo =
! when path is not supplied.
Example for ~/.hgrc:
[extensions]
# (the churn extension will get loaded from Mercurial's path)
churn =
# (this extension will get loaded from the file specified)
myfeature = ~/.hgext/myfeature.py
format
Configuration that controls the repository format. Newer format options
are more powerful but incompatible with some older versions of Mercu-
rial. Format options are considered at repository initialization only.
You need to make a new clone for config change to be taken into
account.
For more details about repository format and version compatibility, see
https://www.mercurial-scm.org/wiki/MissingRequirement
usegeneraldelta
Enable or disable the "generaldelta" repository format which
improves repository compression by allowing "revlog" to store
delta against arbitrary revision instead of the previous stored
one. This provides significant improvement for repositories with
branches.
Repositories with this on-disk format require Mercurial version
1.9.
Enabled by default.
dotencode
Enable or disable the "dotencode" repository format which
enhances the "fncache" repository format (which has to be
enabled to use dotencode) to avoid issues with filenames start-
ing with ._ on Mac OS X and spaces on Windows.
Repositories with this on-disk format require Mercurial version
1.7.
Enabled by default.
usefncache
Enable or disable the "fncache" repository format which enhances
the "store" repository format (which has to be enabled to use
fncache) to allow longer filenames and avoids using Windows
reserved names, e.g. "nul".
Repositories with this on-disk format require Mercurial version
1.1.
Enabled by default.
usestore
Enable or disable the "store" repository format which improves
compatibility with systems that fold case or otherwise mangle
filenames. Disabling this option will allow you to store longer
filenames in some situations at the expense of compatibility.
Repositories with this on-disk format require Mercurial version
0.9.4.
Enabled by default.
sparse-revlog
Enable or disable the sparse-revlog delta strategy. This format
improves delta re-use inside revlog. For very branchy reposito-
ries, it results in a smaller store. For repositories with many
revisions, it also helps performance (by using shortened delta
chains.)
Repositories with this on-disk format require Mercurial version
4.7
Enabled by default.
revlog-compression
Compression algorithm used by revlog. Supported value are zlib
and zstd. The zlib engine is the historical default of Mercu-
rial. zstd is a newer format that is usually a net win over zlib
operating faster at better compression rate. Use zstd to reduce
CPU usage.
On some system, Mercurial installation may lack zstd supports.
Default is zlib.
bookmarks-in-store
Store bookmarks in .hg/store/. This means that bookmarks are
shared when using hg share regardless of the -B option.
Repositories with this on-disk format require Mercurial version
5.1.
Disabled by default.
graph
Web graph view configuration. This section let you change graph ele-
ments display properties by branches, for instance to make the default
branch stand out.
Each line has the following format:
<branch>.<argument> = <value>
where <branch> is the name of the branch being customized. Example:
[graph]
# 2px width
default.width = 2
# red color
default.color = FF0000
Supported arguments:
width
Set branch edges width in pixels.
color
Set branch edges color in hexadecimal RGB notation.
hooks
Commands or Python functions that get automatically executed by various
actions such as starting or finishing a commit. Multiple hooks can be
run for the same action by appending a suffix to the action. Overriding
a site-wide hook can be done by changing its value or setting it to an
empty string. Hooks can be prioritized by adding a prefix of priority.
to the hook name on a new line and setting the priority. The default
priority is 0.
Example .hg/hgrc:
[hooks]
# update working directory after adding changesets
changegroup.update = hg update
# do not use the site-wide hook
incoming =
incoming.email = /my/email/hook
incoming.autobuild = /my/build/hook
# force autobuild hook to run before other incoming hooks
priority.incoming.autobuild = 1
Most hooks are run with environment variables set that give useful
additional information. For each hook below, the environment variables
it is passed are listed with names in the form $HG_foo. The $HG_HOOK-
TYPE and $HG_HOOKNAME variables are set for all hooks. They contain
the type of hook which triggered the run and the full name of the hook
in the config, respectively. In the example above, this will be
$HG_HOOKTYPE=incoming and $HG_HOOKNAME=incoming.email.
changegroup
Run after a changegroup has been added via push, pull or unbun-
dle. The ID of the first new changeset is in $HG_NODE and last
is in $HG_NODE_LAST. The URL from which changes came is in
$HG_URL.
commit
Run after a changeset has been created in the local repository.
The ID of the newly created changeset is in $HG_NODE. Parent
changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
incoming
Run after a changeset has been pulled, pushed, or unbundled into
the local repository. The ID of the newly arrived changeset is
in $HG_NODE. The URL that was source of the changes is in
$HG_URL.
outgoing
Run after sending changes from the local repository to another.
The ID of first changeset sent is in $HG_NODE. The source of
operation is in $HG_SOURCE. Also see hg help config.hooks.pre-
outgoing.
post-<command>
Run after successful invocations of the associated command. The
contents of the command line are passed as $HG_ARGS and the
result code in $HG_RESULT. Parsed command line arguments are
passed as $HG_PATS and $HG_OPTS. These contain string represen-
tations of the python data internally passed to <command>.
$HG_OPTS is a dictionary of options (with unspecified options
set to their defaults). $HG_PATS is a list of arguments. Hook
failure is ignored.
fail-<command>
Run after a failed invocation of an associated command. The con-
tents of the command line are passed as $HG_ARGS. Parsed command
line arguments are passed as $HG_PATS and $HG_OPTS. These con-
tain string representations of the python data internally passed
to <command>. $HG_OPTS is a dictionary of options (with unspeci-
fied options set to their defaults). $HG_PATS is a list of argu-
ments. Hook failure is ignored.
pre-<command>
Run before executing the associated command. The contents of the
command line are passed as $HG_ARGS. Parsed command line argu-
ments are passed as $HG_PATS and $HG_OPTS. These contain string
representations of the data internally passed to <command>.
$HG_OPTS is a dictionary of options (with unspecified options
set to their defaults). $HG_PATS is a list of arguments. If the
hook returns failure, the command doesn't execute and Mercurial
returns the failure code.
prechangegroup
Run before a changegroup is added via push, pull or unbundle.
Exit status 0 allows the changegroup to proceed. A non-zero sta-
tus will cause the push, pull or unbundle to fail. The URL from
which changes will come is in $HG_URL.
precommit
Run before starting a local commit. Exit status 0 allows the
commit to proceed. A non-zero status will cause the commit to
fail. Parent changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
prelistkeys
Run before listing pushkeys (like bookmarks) in the repository.
A non-zero status will cause failure. The key namespace is in
$HG_NAMESPACE.
preoutgoing
Run before collecting changes to send from the local repository
to another. A non-zero status will cause failure. This lets you
prevent pull over HTTP or SSH. It can also prevent propagating
commits (via local pull, push (outbound) or bundle commands),
but not completely, since you can just copy files instead. The
source of operation is in $HG_SOURCE. If "serve", the operation
is happening on behalf of a remote SSH or HTTP repository. If
"push", "pull" or "bundle", the operation is happening on behalf
of a repository on same system.
prepushkey
Run before a pushkey (like a bookmark) is added to the reposi-
tory. A non-zero status will cause the key to be rejected. The
key namespace is in $HG_NAMESPACE, the key is in $HG_KEY, the
old value (if any) is in $HG_OLD, and the new value is in
$HG_NEW.
pretag
Run before creating a tag. Exit status 0 allows the tag to be
created. A non-zero status will cause the tag to fail. The ID of
the changeset to tag is in $HG_NODE. The name of tag is in
$HG_TAG. The tag is local if $HG_LOCAL=1, or in the repository
if $HG_LOCAL=0.
pretxnopen
Run before any new repository transaction is open. The reason
for the transaction will be in $HG_TXNNAME, and a unique identi-
fier for the transaction will be in HG_TXNID. A non-zero status
will prevent the transaction from being opened.
pretxnclose
Run right before the transaction is actually finalized. Any
repository change will be visible to the hook program. This lets
you validate the transaction content or change it. Exit status 0
allows the commit to proceed. A non-zero status will cause the
transaction to be rolled back. The reason for the transaction
opening will be in $HG_TXNNAME, and a unique identifier for the
transaction will be in HG_TXNID. The rest of the available data
will vary according the transaction type. New changesets will
add $HG_NODE (the ID of the first added changeset),
$HG_NODE_LAST (the ID of the last added changeset), $HG_URL and
$HG_SOURCE variables. Bookmark and phase changes will set
HG_BOOKMARK_MOVED and HG_PHASES_MOVED to 1 respectively, etc.
pretxnclose-bookmark
Run right before a bookmark change is actually finalized. Any
repository change will be visible to the hook program. This lets
you validate the transaction content or change it. Exit status 0
allows the commit to proceed. A non-zero status will cause the
transaction to be rolled back. The name of the bookmark will be
available in $HG_BOOKMARK, the new bookmark location will be
available in $HG_NODE while the previous location will be avail-
able in $HG_OLDNODE. In case of a bookmark creation $HG_OLDNODE
will be empty. In case of deletion $HG_NODE will be empty. In
addition, the reason for the transaction opening will be in
$HG_TXNNAME, and a unique identifier for the transaction will be
in HG_TXNID.
pretxnclose-phase
Run right before a phase change is actually finalized. Any
repository change will be visible to the hook program. This lets
you validate the transaction content or change it. Exit status 0
allows the commit to proceed. A non-zero status will cause the
transaction to be rolled back. The hook is called multiple
times, once for each revision affected by a phase change. The
affected node is available in $HG_NODE, the phase in $HG_PHASE
while the previous $HG_OLDPHASE. In case of new node, $HG_OLD-
PHASE will be empty. In addition, the reason for the transac-
tion opening will be in $HG_TXNNAME, and a unique identifier for
the transaction will be in HG_TXNID. The hook is also run for
newly added revisions. In this case the $HG_OLDPHASE entry will
be empty.
txnclose
Run after any repository transaction has been committed. At this
point, the transaction can no longer be rolled back. The hook
will run after the lock is released. See hg help con-
fig.hooks.pretxnclose for details about available variables.
txnclose-bookmark
Run after any bookmark change has been committed. At this point,
the transaction can no longer be rolled back. The hook will run
after the lock is released. See hg help config.hooks.pretxn-
close-bookmark for details about available variables.
txnclose-phase
Run after any phase change has been committed. At this point,
the transaction can no longer be rolled back. The hook will run
after the lock is released. See hg help config.hooks.pretxn-
close-phase for details about available variables.
txnabort
Run when a transaction is aborted. See hg help con-
fig.hooks.pretxnclose for details about available variables.
pretxnchangegroup
Run after a changegroup has been added via push, pull or unbun-
dle, but before the transaction has been committed. The change-
group is visible to the hook program. This allows validation of
incoming changes before accepting them. The ID of the first new
changeset is in $HG_NODE and last is in $HG_NODE_LAST. Exit sta-
tus 0 allows the transaction to commit. A non-zero status will
cause the transaction to be rolled back, and the push, pull or
unbundle will fail. The URL that was the source of changes is in
$HG_URL.
pretxncommit
Run after a changeset has been created, but before the transac-
tion is committed. The changeset is visible to the hook program.
This allows validation of the commit message and changes. Exit
status 0 allows the commit to proceed. A non-zero status will
cause the transaction to be rolled back. The ID of the new
changeset is in $HG_NODE. The parent changeset IDs are in
$HG_PARENT1 and $HG_PARENT2.
preupdate
Run before updating the working directory. Exit status 0 allows
the update to proceed. A non-zero status will prevent the
update. The changeset ID of first new parent is in $HG_PARENT1.
If updating to a merge, the ID of second new parent is in
$HG_PARENT2.
listkeys
Run after listing pushkeys (like bookmarks) in the repository.
The key namespace is in $HG_NAMESPACE. $HG_VALUES is a dictio-
nary containing the keys and values.
pushkey
Run after a pushkey (like a bookmark) is added to the reposi-
tory. The key namespace is in $HG_NAMESPACE, the key is in
$HG_KEY, the old value (if any) is in $HG_OLD, and the new value
is in $HG_NEW.
tag
Run after a tag is created. The ID of the tagged changeset is in
$HG_NODE. The name of tag is in $HG_TAG. The tag is local if
$HG_LOCAL=1, or in the repository if $HG_LOCAL=0.
update
Run after updating the working directory. The changeset ID of
first new parent is in $HG_PARENT1. If updating to a merge, the
ID of second new parent is in $HG_PARENT2. If the update suc-
ceeded, $HG_ERROR=0. If the update failed (e.g. because con-
flicts were not resolved), $HG_ERROR=1.
Note It is generally better to use standard hooks rather than the
generic pre- and post- command hooks, as they are guaranteed to
be called in the appropriate contexts for influencing transac-
tions. Also, hooks like "commit" will be called in all contexts
that generate a commit (e.g. tag) and not just the commit com-
mand.
The syntax for Python hooks is as follows:
hookname = python:modulename.submodule.callable
hookname = python:/path/to/python/module.py:callable
Python hooks are run within the Mercurial process. Each hook is called
with at least three keyword arguments: a ui object (keyword ui), a
repository object (keyword repo), and a hooktype keyword that tells
what kind of hook is used. Arguments listed as environment variables
above are passed as keyword arguments, with no HG_ prefix, and names in
lower case.
If a Python hook returns a "true" value or raises an exception, this is
treated as a failure.
hostfingerprints
(Deprecated. Use [hostsecurity]'s fingerprints options instead.)
Fingerprints of the certificates of known HTTPS servers.
A HTTPS connection to a server with a fingerprint configured here will
only succeed if the servers certificate matches the fingerprint. This
is very similar to how ssh known hosts works.
The fingerprint is the SHA-1 hash value of the DER encoded certificate.
Multiple values can be specified (separated by spaces or commas). This
can be used to define both old and new fingerprints while a host tran-
sitions to a new certificate.
The CA chain and web.cacerts is not used for servers with a finger-
print.
For example:
[hostfingerprints]
hg.intevation.de = fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33
hg.intevation.org = fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33
hostsecurity
Used to specify global and per-host security settings for connecting to
other machines.
The following options control default behavior for all hosts.
ciphers
Defines the cryptographic ciphers to use for connections.
Value must be a valid OpenSSL Cipher List Format as documented
at https://www.openssl.org/docs/manmas-
ter/apps/ciphers.html#CIPHER-LIST-FORMAT.
This setting is for advanced users only. Setting to incorrect
values can significantly lower connection security or decrease
performance. You have been warned.
This option requires Python 2.7.
minimumprotocol
Defines the minimum channel encryption protocol to use.
By default, the highest version of TLS supported by both client
and server is used.
Allowed values are: tls1.0, tls1.1, tls1.2.
When running on an old Python version, only tls1.0 is allowed
since old versions of Python only support up to TLS 1.0.
When running a Python that supports modern TLS versions, the
default is tls1.1. tls1.0 can still be used to allow TLS 1.0.
However, this weakens security and should only be used as a fea-
ture of last resort if a server does not support TLS 1.1+.
Options in the [hostsecurity] section can have the form hostname:set-
ting. This allows multiple settings to be defined on a per-host basis.
The following per-host settings can be defined.
ciphers
This behaves like ciphers as described above except it only
applies to the host on which it is defined.
fingerprints
A list of hashes of the DER encoded peer/remote certificate.
Values have the form algorithm:fingerprint. e.g.
sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2.
In addition, colons (:) can appear in the fingerprint part.
The following algorithms/prefixes are supported: sha1, sha256,
sha512.
Use of sha256 or sha512 is preferred.
If a fingerprint is specified, the CA chain is not validated for
this host and Mercurial will require the remote certificate to
match one of the fingerprints specified. This means if the
server updates its certificate, Mercurial will abort until a new
fingerprint is defined. This can provide stronger security than
traditional CA-based validation at the expense of convenience.
This option takes precedence over verifycertsfile.
minimumprotocol
This behaves like minimumprotocol as described above except it
only applies to the host on which it is defined.
verifycertsfile
Path to file a containing a list of PEM encoded certificates
used to verify the server certificate. Environment variables and
~user constructs are expanded in the filename.
The server certificate or the certificate's certificate author-
ity (CA) must match a certificate from this file or certificate
verification will fail and connections to the server will be
refused.
If defined, only certificates provided by this file will be
used: web.cacerts and any system/default certificates will not
be used.
This option has no effect if the per-host fingerprints option is
set.
The format of the file is as follows:
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
For example:
[hostsecurity]
hg.example.com:fingerprints = sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2
hg2.example.com:fingerprints = sha1:914f1aff87249c09b6859b88b1906d30756491ca, sha1:fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33
hg3.example.com:fingerprints = sha256:9a:b0:dc:e2:75:ad:8a:b7:84:58:e5:1f:07:32:f1:87:e6:bd:24:22:af:b7:ce:8e:9c:b4:10:cf:b9:f4:0e:d2
foo.example.com:verifycertsfile = /etc/ssl/trusted-ca-certs.pem
To change the default minimum protocol version to TLS 1.2 but to allow
TLS 1.1 when connecting to hg.example.com:
[hostsecurity]
minimumprotocol = tls1.2
hg.example.com:minimumprotocol = tls1.1
http_proxy
Used to access web-based Mercurial repositories through a HTTP proxy.
host
Host name and (optional) port of the proxy server, for example
"myproxy:8000".
no
Optional. Comma-separated list of host names that should bypass
the proxy.
passwd
Optional. Password to authenticate with at the proxy server.
user
Optional. User name to authenticate with at the proxy server.
always
Optional. Always use the proxy, even for localhost and any
entries in http_proxy.no. (default: False)
http
Used to configure access to Mercurial repositories via HTTP.
timeout
If set, blocking operations will timeout after that many sec-
onds. (default: None)
merge
This section specifies behavior during merges and updates.
checkignored
Controls behavior when an ignored file on disk has the same name
as a tracked file in the changeset being merged or updated to,
and has different contents. Options are abort, warn and ignore.
With abort, abort on such files. With warn, warn on such files
and back them up as .orig. With ignore, don't print a warning
and back them up as .orig. (default: abort)
checkunknown
Controls behavior when an unknown file that isn't ignored has
the same name as a tracked file in the changeset being merged or
updated to, and has different contents. Similar to merge.check-
ignored, except for files that are not ignored. (default: abort)
on-failure
When set to continue (the default), the merge process attempts
to merge all unresolved files using the merge chosen tool,
regardless of whether previous file merge attempts during the
process succeeded or not. Setting this to prompt will prompt
after any merge failure continue or halt the merge process. Set-
ting this to halt will automatically halt the merge process on
any merge tool failure. The merge process can be restarted by
using the resolve command. When a merge is halted, the reposi-
tory is left in a normal unresolved merge state. (default: con-
tinue)
strict-capability-check
Whether capabilities of internal merge tools are checked
strictly or not, while examining rules to decide merge tool to
be used. (default: False)
merge-patterns
This section specifies merge tools to associate with particular file
patterns. Tools matched here will take precedence over the default
merge tool. Patterns are globs by default, rooted at the repository
root.
Example:
[merge-patterns]
**.c = kdiff3
**.jpg = myimgmerge
merge-tools
This section configures external merge tools to use for file-level
merges. This section has likely been preconfigured at install time.
Use hg config merge-tools to check the existing configuration. Also
see hg help merge-tools for more details.
Example ~/.hgrc:
[merge-tools]
# Override stock tool location
kdiff3.executable = ~/bin/kdiff3
# Specify command line
kdiff3.args = $base $local $other -o $output
# Give higher priority
kdiff3.priority = 1
# Changing the priority of preconfigured tool
meld.priority = 0
# Disable a preconfigured tool
vimdiff.disabled = yes
# Define new tool
myHtmlTool.args = -m $local $other $base $output
myHtmlTool.priority = 1
Supported arguments:
priority
The priority in which to evaluate this tool. (default: 0)
executable
Either just the name of the executable or its pathname.
(default: the tool name)
args
The arguments to pass to the tool executable. You can refer to
the files being merged as well as the output file through these
variables: $base, $local, $other, $output.
The meaning of $local and $other can vary depending on which
action is being performed. During an update or merge, $local
represents the original state of the file, while $other repre-
sents the commit you are updating to or the commit you are merg-
ing with. During a rebase, $local represents the destination of
the rebase, and $other represents the commit being rebased.
Some operations define custom labels to assist with identifying
the revisions, accessible via $labellocal, $labelother, and
$labelbase. If custom labels are not available, these will be
local, other, and base, respectively. (default: $local $base
$other)
premerge
Attempt to run internal non-interactive 3-way merge tool before
launching external tool. Options are true, false, keep or
keep-merge3. The keep option will leave markers in the file if
the premerge fails. The keep-merge3 will do the same but include
information about the base of the merge in the marker (see
internal :merge3 in hg help merge-tools). (default: True)
binary
This tool can merge binary files. (default: False, unless tool
was selected by file pattern match)
symlink
This tool can merge symlinks. (default: False)
check
A list of merge success-checking options:
changed
Ask whether merge was successful when the merged file
shows no changes.
conflicts
Check whether there are conflicts even though the tool
reported success.
prompt
Always prompt for merge success, regardless of success
reported by tool.
fixeol
Attempt to fix up EOL changes caused by the merge tool.
(default: False)
gui
This tool requires a graphical interface to run. (default:
False)
mergemarkers
Controls whether the labels passed via $labellocal, $labelother,
and $labelbase are detailed (respecting mergemarkertemplate) or
basic. If premerge is keep or keep-merge3, the conflict markers
generated during premerge will be detailed if either this option
or the corresponding option in the [ui] section is detailed.
(default: basic)
mergemarkertemplate
This setting can be used to override mergemarkertemplate from
the [ui] section on a per-tool basis; this applies to the
$label-prefixed variables and to the conflict markers that are
generated if premerge is keep` or ``keep-merge3. See the corre-
sponding variable in [ui] for more information.
pager
Setting used to control when to paginate and with what external tool.
See hg help pager for details.
pager
Define the external tool used as pager.
If no pager is set, Mercurial uses the environment variable
$PAGER. If neither pager.pager, nor $PAGER is set, a default
pager will be used, typically less on Unix and more on Windows.
Example:
[pager]
pager = less -FRX
ignore
List of commands to disable the pager for. Example:
[pager]
ignore = version, help, update
patch
Settings used when applying patches, for instance through the 'import'
command or with Mercurial Queues extension.
eol
When set to 'strict' patch content and patched files end of
lines are preserved. When set to lf or crlf, both files end of
lines are ignored when patching and the result line endings are
normalized to either LF (Unix) or CRLF (Windows). When set to
auto, end of lines are again ignored while patching but line
endings in patched files are normalized to their original set-
ting on a per-file basis. If target file does not exist or has
no end of line, patch line endings are preserved. (default:
strict)
fuzz
The number of lines of 'fuzz' to allow when applying patches.
This controls how much context the patcher is allowed to ignore
when trying to apply a patch. (default: 2)
paths
Assigns symbolic names and behavior to repositories.
Options are symbolic names defining the URL or directory that is the
location of the repository. Example:
[paths]
my_server = https://example.com/my_repo
local_path = /home/me/repo
These symbolic names can be used from the command line. To pull from
my_server: hg pull my_server. To push to local_path: hg push
local_path.
Options containing colons (:) denote sub-options that can influence
behavior for that specific path. Example:
[paths]
my_server = https://example.com/my_path
my_server:pushurl = ssh://example.com/my_path
The following sub-options can be defined:
pushurl
The URL to use for push operations. If not defined, the location
defined by the path's main entry is used.
pushrev
A revset defining which revisions to push by default.
When hg push is executed without a -r argument, the revset
defined by this sub-option is evaluated to determine what to
push.
For example, a value of . will push the working directory's
revision by default.
Revsets specifying bookmarks will not result in the bookmark
being pushed.
The following special named paths exist:
default
The URL or directory to use when no source or remote is speci-
fied.
hg clone will automatically define this path to the location the
repository was cloned from.
default-push
(deprecated) The URL or directory for the default hg push loca-
tion. default:pushurl should be used instead.
phases
Specifies default handling of phases. See hg help phases for more
information about working with phases.
publish
Controls draft phase behavior when working as a server. When
true, pushed changesets are set to public in both client and
server and pulled or cloned changesets are set to public in the
client. (default: True)
new-commit
Phase of newly-created commits. (default: draft)
checksubrepos
Check the phase of the current revision of each subrepository.
Allowed values are "ignore", "follow" and "abort". For settings
other than "ignore", the phase of the current revision of each
subrepository is checked before committing the parent reposi-
tory. If any of those phases is greater than the phase of the
parent repository (e.g. if a subrepo is in a "secret" phase
while the parent repo is in "draft" phase), the commit is either
aborted (if checksubrepos is set to "abort") or the higher phase
is used for the parent repository commit (if set to "follow").
(default: follow)
profiling
Specifies profiling type, format, and file output. Two profilers are
supported: an instrumenting profiler (named ls), and a sampling pro-
filer (named stat).
In this section description, 'profiling data' stands for the raw data
collected during profiling, while 'profiling report' stands for a sta-
tistical text report generated from the profiling data.
enabled
Enable the profiler. (default: false)
This is equivalent to passing --profile on the command line.
type
The type of profiler to use. (default: stat)
ls
Use Python's built-in instrumenting profiler. This pro-
filer works on all platforms, but each line number it
reports is the first line of a function. This restriction
makes it difficult to identify the expensive parts of a
non-trivial function.
stat
Use a statistical profiler, statprof. This profiler is
most useful for profiling commands that run for longer
than about 0.1 seconds.
format
Profiling format. Specific to the ls instrumenting profiler.
(default: text)
text
Generate a profiling report. When saving to a file, it
should be noted that only the report is saved, and the
profiling data is not kept.
kcachegrind
Format profiling data for kcachegrind use: when saving to
a file, the generated file can directly be loaded into
kcachegrind.
statformat
Profiling format for the stat profiler. (default: hotpath)
hotpath
Show a tree-based display containing the hot path of exe-
cution (where most time was spent).
bymethod
Show a table of methods ordered by how frequently they
are active.
byline
Show a table of lines in files ordered by how frequently
they are active.
json
Render profiling data as JSON.
frequency
Sampling frequency. Specific to the stat sampling profiler.
(default: 1000)
output
File path where profiling data or report should be saved. If the
file exists, it is replaced. (default: None, data is printed on
stderr)
sort
Sort field. Specific to the ls instrumenting profiler. One of
callcount, reccallcount, totaltime and inlinetime. (default:
inlinetime)
time-track
Control if the stat profiler track cpu or real time. (default:
cpu on Windows, otherwise real)
limit
Number of lines to show. Specific to the ls instrumenting pro-
filer. (default: 30)
nested
Show at most this number of lines of drill-down info after each
main entry. This can help explain the difference between Total
and Inline. Specific to the ls instrumenting profiler.
(default: 0)
showmin
Minimum fraction of samples an entry must have for it to be dis-
played. Can be specified as a float between 0.0 and 1.0 or can
have a % afterwards to allow values up to 100. e.g. 5%.
Only used by the stat profiler.
For the hotpath format, default is 0.05. For the chrome format,
default is 0.005.
The option is unused on other formats.
showmax
Maximum fraction of samples an entry can have before it is
ignored in display. Values format is the same as showmin.
Only used by the stat profiler.
For the chrome format, default is 0.999.
The option is unused on other formats.
showtime
Show time taken as absolute durations, in addition to percent-
ages. Only used by the hotpath format. (default: true)
progress
Mercurial commands can draw progress bars that are as informative as
possible. Some progress bars only offer indeterminate information,
while others have a definite end point.
debug
Whether to print debug info when updating the progress bar.
(default: False)
delay
Number of seconds (float) before showing the progress bar.
(default: 3)
changedelay
Minimum delay before showing a new topic. When set to less than
3 * refresh, that value will be used instead. (default: 1)
estimateinterval
Maximum sampling interval in seconds for speed and estimated
time calculation. (default: 60)
refresh
Time in seconds between refreshes of the progress bar. (default:
0.1)
format
Format of the progress bar.
Valid entries for the format field are topic, bar, number, unit,
estimate, speed, and item. item defaults to the last 20 charac-
ters of the item, but this can be changed by adding either
-<num> which would take the last num characters, or +<num> for
the first num characters.
(default: topic bar number estimate)
width
If set, the maximum width of the progress information (that is,
min(width, term width) will be used).
clear-complete
Clear the progress bar after it's done. (default: True)
disable
If true, don't show a progress bar.
assume-tty
If true, ALWAYS show a progress bar, unless disable is given.
rebase
evolution.allowdivergence
Default to False, when True allow creating divergence when per-
forming rebase of obsolete changesets.
revsetalias
Alias definitions for revsets. See hg help revsets for details.
rewrite
backup-bundle
Whether to save stripped changesets to a bundle file. (default:
True)
update-timestamp
If true, updates the date and time of the changeset to current.
It is only applicable for hg amend in current version.
storage
Control the strategy Mercurial uses internally to store history.
Options in this category impact performance and repository size.
revlog.optimize-delta-parent-choice
When storing a merge revision, both parents will be equally con-
sidered as a possible delta base. This results in better delta
selection and improved revlog compression. This option is
enabled by default.
Turning this option off can result in large increase of reposi-
tory size for repository with many merges.
revlog.reuse-external-delta-parent
Control the order in which delta parents are considered when
adding new revisions from an external source. (typically: apply
bundle from hg pull or hg push).
New revisions are usually provided as a delta against other
revisions. By default, Mercurial will try to reuse this delta
first, therefore using the same "delta parent" as the source.
Directly using delta's from the source reduces CPU usage and
usually speeds up operation. However, in some case, the source
might have sub-optimal delta bases and forcing their reevalua-
tion is useful. For example, pushes from an old client could
have sub-optimal delta's parent that the server want to opti-
mize. (lack of general delta, bad parents, choice, lack of
sparse-revlog, etc).
This option is enabled by default. Turning it off will ensure
bad delta parent choices from older client do not propagate to
this repository, at the cost of a small increase in CPU consump-
tion.
Note: this option only control the order in which delta parents
are considered. Even when disabled, the existing delta from the
source will be reused if the same delta parent is selected.
revlog.reuse-external-delta
Control the reuse of delta from external source. (typically:
apply bundle from hg pull or hg push).
New revisions are usually provided as a delta against another
revision. By default, Mercurial will not recompute the same
delta again, trusting externally provided deltas. There have
been rare cases of small adjustment to the diffing algorithm in
the past. So in some rare case, recomputing delta provided by
ancient clients can provides better results. Disabling this
option means going through a full delta recomputation for all
incoming revisions. It means a large increase in CPU usage and
will slow operations down.
This option is enabled by default. When disabled, it also dis-
ables the related storage.revlog.reuse-external-delta-parent
option.
revlog.zlib.level
Zlib compression level used when storing data into the reposi-
tory. Accepted Value range from 1 (lowest compression) to 9
(highest compression). Zlib default value is 6.
revlog.zstd.level
zstd compression level used when storing data into the reposi-
tory. Accepted Value range from 1 (lowest compression) to 22
(highest compression). (default 3)
server
Controls generic server settings.
bookmarks-pushkey-compat
Trigger pushkey hook when being pushed bookmark updates. This
config exist for compatibility purpose (default to True)
If you use pushkey and pre-pushkey hooks to control bookmark
movement we recommend you migrate them to txnclose-bookmark and
pretxnclose-bookmark.
compressionengines
List of compression engines and their relative priority to
advertise to clients.
The order of compression engines determines their priority, the
first having the highest priority. If a compression engine is
not listed here, it won't be advertised to clients.
If not set (the default), built-in defaults are used. Run hg
debuginstall to list available compression engines and their
default wire protocol priority.
Older Mercurial clients only support zlib compression and this
setting has no effect for legacy clients.
uncompressed
Whether to allow clients to clone a repository using the uncom-
pressed streaming protocol. This transfers about 40% more data
than a regular clone, but uses less memory and CPU on both
server and client. Over a LAN (100 Mbps or better) or a very
fast WAN, an uncompressed streaming clone is a lot faster (~10x)
than a regular clone. Over most WAN connections (anything slower
than about 6 Mbps), uncompressed streaming is slower, because of
the extra data transfer overhead. This mode will also temporar-
ily hold the write lock while determining what data to transfer.
(default: True)
uncompressedallowsecret
Whether to allow stream clones when the repository contains
secret changesets. (default: False)
preferuncompressed
When set, clients will try to use the uncompressed streaming
protocol. (default: False)
disablefullbundle
When set, servers will refuse attempts to do pull-based clones.
If this option is set, preferuncompressed and/or clone bundles
are highly recommended. Partial clones will still be allowed.
(default: False)
streamunbundle
When set, servers will apply data sent from the client directly,
otherwise it will be written to a temporary file first. This
option effectively prevents concurrent pushes.
pullbundle
When set, the server will check pullbundle.manifest for bundles
covering the requested heads and common nodes. The first match-
ing entry will be streamed to the client.
For HTTP transport, the stream will still use zlib compression
for older clients.
concurrent-push-mode
Level of allowed race condition between two pushing clients.
o 'strict': push is abort if another client touched the reposi-
tory while the push was preparing. (default)
o 'check-related': push is only aborted if it affects head that
got also affected while the push was preparing.
This requires compatible client (version 4.3 and later). Old client
will use 'strict'.
validate
Whether to validate the completeness of pushed changesets by
checking that all new file revisions specified in manifests are
present. (default: False)
maxhttpheaderlen
Instruct HTTP clients not to send request headers longer than
this many bytes. (default: 1024)
bundle1
Whether to allow clients to push and pull using the legacy bun-
dle1 exchange format. (default: True)
bundle1gd
Like bundle1 but only used if the repository is using the gener-
aldelta storage format. (default: True)
bundle1.push
Whether to allow clients to push using the legacy bundle1
exchange format. (default: True)
bundle1gd.push
Like bundle1.push but only used if the repository is using the
generaldelta storage format. (default: True)
bundle1.pull
Whether to allow clients to pull using the legacy bundle1
exchange format. (default: True)
bundle1gd.pull
Like bundle1.pull but only used if the repository is using the
generaldelta storage format. (default: True)
Large repositories using the generaldelta storage format should
consider setting this option because converting generaldelta
repositories to the exchange format required by the bundle1 data
format can consume a lot of CPU.
bundle2.stream
Whether to allow clients to pull using the bundle2 streaming
protocol. (default: True)
zliblevel
Integer between -1 and 9 that controls the zlib compression
level for wire protocol commands that send zlib compressed out-
put (notably the commands that send repository history data).
The default (-1) uses the default zlib compression level, which
is likely equivalent to 6. 0 means no compression. 9 means maxi-
mum compression.
Setting this option allows server operators to make trade-offs
between bandwidth and CPU used. Lowering the compression lowers
CPU utilization but sends more bytes to clients.
This option only impacts the HTTP server.
zstdlevel
Integer between 1 and 22 that controls the zstd compression
level for wire protocol commands. 1 is the minimal amount of
compression and 22 is the highest amount of compression.
The default (3) should be significantly faster than zlib while
likely delivering better compression ratios.
This option only impacts the HTTP server.
See also server.zliblevel.
view
Repository filter used when exchanging revisions with the peer.
The default view (served) excludes secret and hidden changesets.
Another useful value is immutable (no draft, secret or hidden
changesets). (EXPERIMENTAL)
smtp
Configuration for extensions that need to send email messages.
host
Host name of mail server, e.g. "mail.example.com".
port
Optional. Port to connect to on mail server. (default: 465 if
tls is smtps; 25 otherwise)
tls
Optional. Method to enable TLS when connecting to mail server:
starttls, smtps or none. (default: none)
username
Optional. User name for authenticating with the SMTP server.
(default: None)
password
Optional. Password for authenticating with the SMTP server. If
not specified, interactive sessions will prompt the user for a
password; non-interactive sessions will fail. (default: None)
local_hostname
Optional. The hostname that the sender can use to identify
itself to the MTA.
subpaths
Subrepository source URLs can go stale if a remote server changes name
or becomes temporarily unavailable. This section lets you define re-
write rules of the form:
<pattern> = <replacement>
where pattern is a regular expression matching a subrepository source
URL and replacement is the replacement string used to rewrite it.
Groups can be matched in pattern and referenced in replacements. For
instance:
http://server/(.*)-hg/ = http://hg.server/\1/
rewrites http://server/foo-hg/ into http://hg.server/foo/.
Relative subrepository paths are first made absolute, and the rewrite
rules are then applied on the full (absolute) path. If pattern doesn't
match the full path, an attempt is made to apply it on the relative
path alone. The rules are applied in definition order.
subrepos
This section contains options that control the behavior of the sub-
repositories feature. See also hg help subrepos.
Security note: auditing in Mercurial is known to be insufficient to
prevent clone-time code execution with carefully constructed Git subre-
pos. It is unknown if a similar detect is present in Subversion subre-
pos. Both Git and Subversion subrepos are disabled by default out of
security concerns. These subrepo types can be enabled using the respec-
tive options below.
allowed
Whether subrepositories are allowed in the working directory.
When false, commands involving subrepositories (like hg update)
will fail for all subrepository types. (default: true)
hg:allowed
Whether Mercurial subrepositories are allowed in the working
directory. This option only has an effect if subrepos.allowed is
true. (default: true)
git:allowed
Whether Git subrepositories are allowed in the working direc-
tory. This option only has an effect if subrepos.allowed is
true.
See the security note above before enabling Git subrepos.
(default: false)
svn:allowed
Whether Subversion subrepositories are allowed in the working
directory. This option only has an effect if subrepos.allowed is
true.
See the security note above before enabling Subversion subrepos.
(default: false)
templatealias
Alias definitions for templates. See hg help templates for details.
templates
Use the [templates] section to define template strings. See hg help
templates for details.
trusted
Mercurial will not use the settings in the .hg/hgrc file from a reposi-
tory if it doesn't belong to a trusted user or to a trusted group, as
various hgrc features allow arbitrary commands to be run. This issue is
often encountered when configuring hooks or extensions for shared
repositories or servers. However, the web interface will use some safe
settings from the [web] section.
This section specifies what users and groups are trusted. The current
user is always trusted. To trust everybody, list a user or a group with
name *. These settings must be placed in an already-trusted file to
take effect, such as $HOME/.hgrc of the user or service running Mercu-
rial.
users
Comma-separated list of trusted users.
groups
Comma-separated list of trusted groups.
ui
User interface controls.
archivemeta
Whether to include the .hg_archival.txt file containing meta
data (hashes for the repository base and for tip) in archives
created by the hg archive command or downloaded via hgweb.
(default: True)
askusername
Whether to prompt for a username when committing. If True, and
neither $HGUSER nor $EMAIL has been specified, then the user
will be prompted to enter a username. If no username is entered,
the default USER@HOST is used instead. (default: False)
clonebundles
Whether the "clone bundles" feature is enabled.
When enabled, hg clone may download and apply a server-adver-
tised bundle file from a URL instead of using the normal
exchange mechanism.
This can likely result in faster and more reliable clones.
(default: True)
clonebundlefallback
Whether failure to apply an advertised "clone bundle" from a
server should result in fallback to a regular clone.
This is disabled by default because servers advertising "clone
bundles" often do so to reduce server load. If advertised bun-
dles start mass failing and clients automatically fall back to a
regular clone, this would add significant and unexpected load to
the server since the server is expecting clone operations to be
offloaded to pre-generated bundles. Failing fast (the default
behavior) ensures clients don't overwhelm the server when "clone
bundle" application fails.
(default: False)
clonebundleprefers
Defines preferences for which "clone bundles" to use.
Servers advertising "clone bundles" may advertise multiple
available bundles. Each bundle may have different attributes,
such as the bundle type and compression format. This option is
used to prefer a particular bundle over another.
The following keys are defined by Mercurial:
BUNDLESPEC
A bundle type specifier. These are strings passed to hg
bundle -t. e.g. gzip-v2 or bzip2-v1.
COMPRESSION
The compression format of the bundle. e.g. gzip and
bzip2.
Server operators may define custom keys.
Example values: COMPRESSION=bzip2, BUNDLESPEC=gzip-v2, COMPRES-
SION=gzip.
By default, the first bundle advertised by the server is used.
color
When to colorize output. Possible value are Boolean ("yes" or
"no"), or "debug", or "always". (default: "yes"). "yes" will use
color whenever it seems possible. See hg help color for details.
commitsubrepos
Whether to commit modified subrepositories when committing the
parent repository. If False and one subrepository has uncommit-
ted changes, abort the commit. (default: False)
debug
Print debugging information. (default: False)
editor
The editor to use during a commit. (default: $EDITOR or vi)
fallbackencoding
Encoding to try if it's not possible to decode the changelog
using UTF-8. (default: ISO-8859-1)
graphnodetemplate
The template used to print changeset nodes in an ASCII revision
graph. (default: {graphnode})
ignore
A file to read per-user ignore patterns from. This file should
be in the same format as a repository-wide .hgignore file. File-
names are relative to the repository root. This option supports
hook syntax, so if you want to specify multiple ignore files,
you can do so by setting something like ignore.other = ~/.hgig-
nore2. For details of the ignore file format, see the hgig-
nore(5) man page.
interactive
Allow to prompt the user. (default: True)
interface
Select the default interface for interactive features (default:
text). Possible values are 'text' and 'curses'.
interface.chunkselector
Select the interface for change recording (e.g. hg commit -i).
Possible values are 'text' and 'curses'. This config overrides
the interface specified by ui.interface.
large-file-limit
Largest file size that gives no memory use warning. Possible
values are integers or 0 to disable the check. (default:
10000000)
logtemplate
Template string for commands that print changesets.
merge
The conflict resolution program to use during a manual merge.
For more information on merge tools see hg help merge-tools.
For configuring merge tools see the [merge-tools] section.
mergemarkers
Sets the merge conflict marker label styling. The detailed style
uses the mergemarkertemplate setting to style the labels. The
basic style just uses 'local' and 'other' as the marker label.
One of basic or detailed. (default: basic)
mergemarkertemplate
The template used to print the commit description next to each
conflict marker during merge conflicts. See hg help templates
for the template format.
Defaults to showing the hash, tags, branches, bookmarks, author,
and the first line of the commit description.
If you use non-ASCII characters in names for tags, branches,
bookmarks, authors, and/or commit descriptions, you must pay
attention to encodings of managed files. At template expansion,
non-ASCII characters use the encoding specified by the --encod-
ing global option, HGENCODING or other environment variables
that govern your locale. If the encoding of the merge markers is
different from the encoding of the merged files, serious prob-
lems may occur.
Can be overridden per-merge-tool, see the [merge-tools] section.
message-output
Where to write status and error messages. (default: stdio)
stderr
Everything to stderr.
stdio
Status to stdout, and error to stderr.
origbackuppath
The path to a directory used to store generated .orig files. If
the path is not a directory, one will be created. If set, files
stored in this directory have the same name as the original file
and do not have a .orig suffix.
paginate
Control the pagination of command output (default: True). See hg
help pager for details.
patch
An optional external tool that hg import and some extensions
will use for applying patches. By default Mercurial uses an
internal patch utility. The external tool must work as the com-
mon Unix patch program. In particular, it must accept a -p argu-
ment to strip patch headers, a -d argument to specify the cur-
rent directory, a file name to patch, and a patch file to take
from stdin.
It is possible to specify a patch tool together with extra argu-
ments. For example, setting this option to patch --merge will
use the patch program with its 2-way merge option.
portablefilenames
Check for portable filenames. Can be warn, ignore or abort.
(default: warn)
warn
Print a warning message on POSIX platforms, if a file
with a non-portable filename is added (e.g. a file with a
name that can't be created on Windows because it contains
reserved parts like AUX, reserved characters like :, or
would cause a case collision with an existing file).
ignore
Don't print a warning.
abort
The command is aborted.
true
Alias for warn.
false
Alias for ignore.
pre-merge-tool-output-template
A template that is printed before executing an external merge
tool. This can be used to print out additional context that
might be useful to have during the conflict resolution, such as
the description of the various commits involved or book-
marks/tags.
Additional information is available in the local`, ``base, and
other dicts. For example: {local.label}, {base.name}, or
{other.islink}.
quiet
Reduce the amount of output printed. (default: False)
relative-paths
Prefer relative paths in the UI.
remotecmd
Remote command to use for clone/push/pull operations. (default:
hg)
report_untrusted
Warn if a .hg/hgrc file is ignored due to not being owned by a
trusted user or group. (default: True)
slash
(Deprecated. Use slashpath template filter instead.)
Display paths using a slash (/) as the path separator. This only
makes a difference on systems where the default path separator
is not the slash character (e.g. Windows uses the backslash
character (\)). (default: False)
statuscopies
Display copies in the status command.
ssh
Command to use for SSH connections. (default: ssh)
ssherrorhint
A hint shown to the user in the case of SSH error (e.g. Please
see http://company/internalwiki/ssh.html)
strict
Require exact command names, instead of allowing unambiguous
abbreviations. (default: False)
style
Name of style to use for command output.
supportcontact
A URL where users should report a Mercurial traceback. Use this
if you are a large organisation with its own Mercurial deploy-
ment process and crash reports should be addressed to your
internal support.
textwidth
Maximum width of help text. A longer line generated by hg help
or hg subcommand --help will be broken after white space to get
this width or the terminal width, whichever comes first. A
non-positive value will disable this and the terminal width will
be used. (default: 78)
timeout
The timeout used when a lock is held (in seconds), a negative
value means no timeout. (default: 600)
timeout.warn
Time (in seconds) before a warning is printed about held lock. A
negative value means no warning. (default: 0)
traceback
Mercurial always prints a traceback when an unknown exception
occurs. Setting this to True will make Mercurial print a trace-
back on all exceptions, even those recognized by Mercurial (such
as IOError or MemoryError). (default: False)
tweakdefaults
By default Mercurial's behavior changes very little from release to
release, but over time the recommended config settings shift. Enable
this config to opt in to get automatic tweaks to Mercurial's behav-
ior over time. This config setting will have no effect if HGPLAIN is
set or HGPLAINEXCEPT is set and does not include tweakdefaults.
(default: False)
It currently means:
[ui]
# The rollback command is dangerous. As a rule, don't use it.
rollback = False
# Make `hg status` report copy information
statuscopies = yes
# Prefer curses UIs when available. Revert to plain-text with `text`.
interface = curses
# Make compatible commands emit cwd-relative paths by default.
relative-paths = yes
[commands]
# Grep working directory by default.
grep.all-files = True
# Refuse to perform an `hg update` that would cause a file content merge
update.check = noconflict
# Show conflicts information in `hg status`
status.verbose = True
# Make `hg resolve` with no action (like `-m`) fail instead of re-merging.
resolve.explicit-re-merge = True
[diff]
git = 1
showfunc = 1
word-diff = 1
username
The committer of a changeset created when running "commit".
Typically a person's name and email address, e.g. Fred Widget
<fred@example.com>. Environment variables in the username are
expanded.
(default: $EMAIL or username@hostname. If the username in hgrc
is empty, e.g. if the system admin set username = in the system
hgrc, it has to be specified manually or in a different hgrc
file)
verbose
Increase the amount of output printed. (default: False)
web
Web interface configuration. The settings in this section apply to both
the builtin webserver (started by hg serve) and the script you run
through a webserver (hgweb.cgi and the derivatives for FastCGI and
WSGI).
The Mercurial webserver does no authentication (it does not prompt for
usernames and passwords to validate who users are), but it does do
authorization (it grants or denies access for authenticated users based
on settings in this section). You must either configure your webserver
to do authentication for you, or disable the authorization checks.
For a quick setup in a trusted environment, e.g., a private LAN, where
you want it to accept pushes from anybody, you can use the following
command line:
$ hg --config web.allow-push=* --config web.push_ssl=False serve
Note that this will allow anybody to push anything to the server and
that this should not be used for public servers.
The full set of options is:
accesslog
Where to output the access log. (default: stdout)
address
Interface address to bind to. (default: all)
allow-archive
List of archive format (bz2, gz, zip) allowed for downloading.
(default: empty)
allowbz2
(DEPRECATED) Whether to allow .tar.bz2 downloading of repository
revisions. (default: False)
allowgz
(DEPRECATED) Whether to allow .tar.gz downloading of repository
revisions. (default: False)
allow-pull
Whether to allow pulling from the repository. (default: True)
allow-push
Whether to allow pushing to the repository. If empty or not set,
pushing is not allowed. If the special value *, any remote user
can push, including unauthenticated users. Otherwise, the remote
user must have been authenticated, and the authenticated user
name must be present in this list. The contents of the
allow-push list are examined after the deny_push list.
allow_read
If the user has not already been denied repository access due to
the contents of deny_read, this list determines whether to grant
repository access to the user. If this list is not empty, and
the user is unauthenticated or not present in the list, then
access is denied for the user. If the list is empty or not set,
then access is permitted to all users by default. Setting
allow_read to the special value * is equivalent to it not being
set (i.e. access is permitted to all users). The contents of the
allow_read list are examined after the deny_read list.
allowzip
(DEPRECATED) Whether to allow .zip downloading of repository
revisions. This feature creates temporary files. (default:
False)
archivesubrepos
Whether to recurse into subrepositories when archiving.
(default: False)
baseurl
Base URL to use when publishing URLs in other locations, so
third-party tools like email notification hooks can construct
URLs. Example: http://hgserver/repos/.
cacerts
Path to file containing a list of PEM encoded certificate
authority certificates. Environment variables and ~user con-
structs are expanded in the filename. If specified on the
client, then it will verify the identity of remote HTTPS servers
with these certificates.
To disable SSL verification temporarily, specify --insecure from
command line.
You can use OpenSSL's CA certificate file if your platform has
one. On most Linux systems this will be /etc/ssl/certs/ca-cer-
tificates.crt. Otherwise you will have to generate this file
manually. The form must be as follows:
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
cache
Whether to support caching in hgweb. (default: True)
certificate
Certificate to use when running hg serve.
collapse
With descend enabled, repositories in subdirectories are shown
at a single level alongside repositories in the current path.
With collapse also enabled, repositories residing at a deeper
level than the current path are grouped behind navigable direc-
tory entries that lead to the locations of these repositories.
In effect, this setting collapses each collection of reposito-
ries found within a subdirectory into a single entry for that
subdirectory. (default: False)
comparisoncontext
Number of lines of context to show in side-by-side file compari-
son. If negative or the value full, whole files are shown.
(default: 5)
This setting can be overridden by a context request parameter to
the comparison command, taking the same values.
contact
Name or email address of the person in charge of the repository.
(default: ui.username or $EMAIL or "unknown" if unset or empty)
csp
Send a Content-Security-Policy HTTP header with this value.
The value may contain a special string %nonce%, which will be
replaced by a randomly-generated one-time use value. If the
value contains %nonce%, web.cache will be disabled, as caching
undermines the one-time property of the nonce. This nonce will
also be inserted into <script> elements containing inline
JavaScript.
Note: lots of HTML content sent by the server is derived from
repository data. Please consider the potential for malicious
repository data to "inject" itself into generated HTML content
as part of your security threat model.
deny_push
Whether to deny pushing to the repository. If empty or not set,
push is not denied. If the special value *, all remote users are
denied push. Otherwise, unauthenticated users are all denied,
and any authenticated user name present in this list is also
denied. The contents of the deny_push list are examined before
the allow-push list.
deny_read
Whether to deny reading/viewing of the repository. If this list
is not empty, unauthenticated users are all denied, and any
authenticated user name present in this list is also denied
access to the repository. If set to the special value *, all
remote users are denied access (rarely needed ;). If deny_read
is empty or not set, the determination of repository access
depends on the presence and content of the allow_read list (see
description). If both deny_read and allow_read are empty or not
set, then access is permitted to all users by default. If the
repository is being served via hgwebdir, denied users will not
be able to see it in the list of repositories. The contents of
the deny_read list have priority over (are examined before) the
contents of the allow_read list.
descend
hgwebdir indexes will not descend into subdirectories. Only
repositories directly in the current path will be shown (other
repositories are still available from the index corresponding to
their containing path).
description
Textual description of the repository's purpose or contents.
(default: "unknown")
encoding
Character encoding name. (default: the current locale charset)
Example: "UTF-8".
errorlog
Where to output the error log. (default: stderr)
guessmime
Control MIME types for raw download of file content. Set to
True to let hgweb guess the content type from the file exten-
sion. This will serve HTML files as text/html and might allow
cross-site scripting attacks when serving untrusted reposito-
ries. (default: False)
hidden
Whether to hide the repository in the hgwebdir index. (default:
False)
ipv6
Whether to use IPv6. (default: False)
labels
List of string labels associated with the repository.
Labels are exposed as a template keyword and can be used to cus-
tomize output. e.g. the index template can group or filter
repositories by labels and the summary template can display
additional content if a specific label is present.
logoimg
File name of the logo image that some templates display on each
page. The file name is relative to staticurl. That is, the full
path to the logo image is "staticurl/logoimg". If unset, hgl-
ogo.png will be used.
logourl
Base URL to use for logos. If unset, https://mercurial-scm.org/
will be used.
maxchanges
Maximum number of changes to list on the changelog. (default:
10)
maxfiles
Maximum number of files to list per changeset. (default: 10)
maxshortchanges
Maximum number of changes to list on the shortlog, graph or
filelog pages. (default: 60)
name
Repository name to use in the web interface. (default: current
working directory)
port
Port to listen on. (default: 8000)
prefix
Prefix path to serve from. (default: '' (server root))
push_ssl
Whether to require that inbound pushes be transported over SSL
to prevent password sniffing. (default: True)
refreshinterval
How frequently directory listings re-scan the filesystem for new
repositories, in seconds. This is relevant when wildcards are
used to define paths. Depending on how much filesystem traversal
is required, refreshing may negatively impact performance.
Values less than or equal to 0 always refresh. (default: 20)
server-header
Value for HTTP Server response header.
static
Directory where static files are served from.
staticurl
Base URL to use for static files. If unset, static files (e.g.
the hgicon.png favicon) will be served by the CGI script itself.
Use this setting to serve them directly with the HTTP server.
Example: http://hgserver/static/.
stripes
How many lines a "zebra stripe" should span in multi-line out-
put. Set to 0 to disable. (default: 1)
style
Which template map style to use. The available options are the
names of subdirectories in the HTML templates path. (default:
paper) Example: monoblue.
templates
Where to find the HTML templates. The default path to the HTML
templates can be obtained from hg debuginstall.
websub
Web substitution filter definition. You can use this section to define
a set of regular expression substitution patterns which let you auto-
matically modify the hgweb server output.
The default hgweb templates only apply these substitution patterns on
the revision description fields. You can apply them anywhere you want
when you create your own templates by adding calls to the "websub" fil-
ter (usually after calling the "escape" filter).
This can be used, for example, to convert issue references to links to
your issue tracker, or to convert "markdown-like" syntax into HTML (see
the examples below).
Each entry in this section names a substitution filter. The value of
each entry defines the substitution expression itself. The websub
expressions follow the old interhg extension syntax, which in turn imi-
tates the Unix sed replacement syntax:
patternname = s/SEARCH_REGEX/REPLACE_EXPRESSION/[i]
You can use any separator other than "/". The final "i" is optional and
indicates that the search must be case insensitive.
Examples:
[websub]
issues = s|issue(\d+)|<a href="http://bts.example.org/issue\1">issue\1</a>|i
italic = s/\b_(\S+)_\b/<i>\1<\/i>/
bold = s/\*\b(\S+)\b\*/<b>\1<\/b>/
worker
Parallel master/worker configuration. We currently perform working
directory updates in parallel on Unix-like systems, which greatly helps
performance.
enabled
Whether to enable workers code to be used. (default: true)
numcpus
Number of CPUs to use for parallel operations. A zero or nega-
tive value is treated as use the default. (default: 4 or the
number of CPUs on the system, whichever is larger)
backgroundclose
Whether to enable closing file handles on background threads
during certain operations. Some platforms aren't very efficient
at closing file handles that have been written or appended to.
By performing file closing on background threads, file write
rate can increase substantially. (default: true on Windows,
false elsewhere)
backgroundcloseminfilecount
Minimum number of files required to trigger background file
closing. Operations not writing this many files won't start
background close threads. (default: 2048)
backgroundclosemaxqueue
The maximum number of opened file handles waiting to be closed
in the background. This option only has an effect if background-
close is enabled. (default: 384)
backgroundclosethreadcount
Number of threads to process background file closes. Only rele-
vant if backgroundclose is enabled. (default: 4)
