NAME
sconsign - print SCons signature file information
SYNOPSIS
sconsign [options...] [file...]
DESCRIPTION
Displays the contents of one or more sconsign files, the signature
database files used by the SCons build tool.
By default, sconsign dumps the entire contents of the sconsign file(s).
Without options, individual dependency entries are printed in the
following format:
depfile: signature timestamp length
implicit_dependency_1: content_signature timestamp length
implicit_dependency_2: content_signature timestamp length
...
action_signature [action string]
None is printed in place of any missing timestamp, content signature
(csig) or build action signature values for any entry or any of its
dependencies. If the entry has no implicit dependencies, or no build
action, those lines are omitted.
By default, sconsign assumes that any file arguments that end with a
.dblite suffix contains signature entries for more than one directory
(that is, was specified by the SConsignFile function). Any file
argument that has no suffix is assumed to be an old-style sconsign file
containing the signature entries for a single directory. If neither of
those is true, sconsign attempts to guess the format. If that does not
work, an explicit format may be specified using the -f or --format=
options.
If there are no file arguments, the name .sconsign.dblite is assumed by
default.
OPTIONS
Various options control what information is printed and the format:
-a, --act, --action
Prints only the build action information for all entries or the
specified entries.
-c, --csig
Prints only the content signature (csig) information for all
entries or the specified entries.
-d DIRECTORY, --dir=DIRECTORY
When the signatures are being read from a .dblite file, or the -f
dblite or --format=dblite options are used, prints information
about only the signatures for entries in the specified DIRECTORY.
-e ENTRY, --entry=ENTRY
Prints information about only the specified ENTRY. Multiple -e
options may be used, in which case information about each ENTRY is
printed in the order in which the options are specified on the
command line.
-f FORMAT, --format=FORMAT
The file(s) to be printed are in the specified FORMAT. Legal values
are dblite (the SCons.dblite format used by default, as well as
when the SConsignFile function is called, except when a filename
argument of None is given) and sconsign (the format used for an
individual .sconsign file in each directory).
-h, --help
Prints a help message and exits.
-i, --implicit
Prints the list of cached implicit dependencies for all entries or
for the specified entries.
--raw
Prints a pretty-printed representation of the raw Python dictionary
that holds build information about individual entries (both the
entry itself and its implicit dependencies). An entry's build
action is still printed in its usual format.
-r, --readable
Prints timestamps in a human-readable string, enclosed in single
quotes.
-t, --timestamp
Prints the timestamp information for all entries or the specified
entries.
-v, --verbose
Prints labels identifying each field being printed.
ENVIRONMENT
SCONS_LIB_DIR
Specifies the directory that contains the SCons Python module
directory (e.g. /home/aroach/scons-src/SCons).
