msggen - generate a machine independent formatted message catalog
msggen [-fls] catfile [msgfile]
msggen merges the message text source file msgfile into a machine independent formatted message catalog catfile. The file catfile is created if it does not already exist. If catfile does exist, its messages are included in the new catfile. If set and message numbers collide, the new message text defined in msgfile replaces the old message text currently contained in catfile.
Non-ASCII characters must be UTF-8 encoded. iconv(1) can be used to convert to/from UTF-8.
The following options are supported:
List the printf(3C) format signature for each message in catfile. A format signature is one line containing one character for each format specification:
List catfile in UTF-8 msgfile form.
Convert the catfile to a message set number and print the number on the standard output.
The following operands are supported:
Machine independent formatted message catalog file.
Message text source file.
Message text source files are in gencat(1) format, defined as follows. The fields of a message text source line are separated by a single blank character. Any other blank characters are considered to be part of the subsequent field. The NL_* constants are defined in one or both of <limits.h> and <nl_types.h>.
A line beginning with a $ followed by a blank character is treated as a comment.
This line deletes message set n from an existing message catalog. n denotes the set number [1, NL_SETMAX]. Any text following the set number is treated as a comment.
This line specifies an optional quote character c, which can be used to surround message-text so that trailing spaces or empty messages are visible in a message source line. By default, or if an empty $quote directive is supplied, no quoting of message-text is recognized.
This line specifies the set identifier of the following messages until the next $set or end-of-file (EOF) appears. n denotes the set identifier, which is defined as a number in the range [1, NL_SETMAX]. Set numbers need not be contiguous. Any text following the set identifier is treated as a comment. If no $set directive is specified in a message text source file, all messages are located in message set 1.
Append translation information to the message catalog header. Only the newest date for a given identification is retained in the catalog. Multiple translation lines are combined into a single, comma-separated list.
m denotes the message identifier, which is defined as a number in the range [1, NL_MSGMAX]. The message-text is stored in the message catalogue with the set identifier specified by the last $set directive, and with message identifier m. If the message-text is empty, and a blank character field separator is present, an empty string is stored in the message catalogue. If a message source line has a message number, but neither a field separator nor message-text, the existing message with that number (if any) is deleted from the catalogue. Message identifiers need not be contiguous. There are no message-text length restrictions.
One or more specified jobs does not exist.
The following example generates a message catalog xxx from the message file xxx.msg:
example% msggen xxx xxx.msg
