msggrep – pattern matching on message catalog

Synopsis

msggrep [OPTION] [INPUTFILE]

Description

Extracts all messages of a translation catalog that match a given pattern or belong to some given source files.

Mandatory arguments to long options are mandatory for short options too.

Input file location:

INPUTFILE: input PO file
-D, –directory=DIRECTORY: add DIRECTORY to list for input files search

If no input file is given or if it is -, standard input is read.

Output file location:

-o, –output-file=FILE: write output to specified file

The results are written to standard output if no output file is specified or if it is -.

Message selection:

[-N SOURCEFILE]… [-M DOMAINNAME]… [-J MSGCTXT-PATTERN] [-K MSGID-PATTERN] [-T MSGSTR-PATTERN] [-C COMMENT-PATTERN] [-X EXTRACTED-COMMENT-PATTERN]

A message is selected if it comes from one of the specified source files, or if it comes from one of the specified domains, or if -J is given and its context (msgctxt) matches MSGCTXT-PATTERN, or if -K is given and its key (msgid or msgid_plural) matches MSGID-PATTERN, or if -T is given and its translation (msgstr) matches MSGSTR-PATTERN, or if -C is given and the translator’s comment matches COMMENT-PATTERN, or if -X is given and the extracted comment matches EXTRACTED-COMMENT-PATTERN.

When more than one selection criterion is specified, the set of selected messages is the union of the selected messages of each criterion.

MSGCTXT-PATTERN or MSGID-PATTERN or MSGSTR-PATTERN or COMMENT-PATTERN or EXTRACTED-COMMENT-PATTERN syntax:

[-E | -F] [-e PATTERN | -f FILE]…

PATTERNs are basic regular expressions by default, or extended regular expressions if -E is given, or fixed strings if -F is given.

-N, –location=SOURCEFILE: select messages extracted from SOURCEFILE
-M, –domain=DOMAINNAME: select messages belonging to domain DOMAINNAME
-J, –msgctxt: start of patterns for the msgctxt
-K, –msgid: start of patterns for the msgid
-T, –msgstr: start of patterns for the msgstr
-C, –comment: start of patterns for the translator’s comment
-X, –extracted-comment: start of patterns for the extracted comment
-E, –extended-regexp: PATTERN is an extended regular expression
-F, –fixed-strings: PATTERN is a set of newline-separated strings
-e, –regexp=PATTERN: use PATTERN as a regular expression
-f, –file=FILE: obtain PATTERN from FILE
-i, –ignore-case: ignore case distinctions
-v, –invert-match: output only the messages that do not match any selection criterion

Input file syntax:

-P, –properties-input: input file is in Java .properties syntax
–stringtable-input: input file is in NeXTstep/GNUstep .strings syntax

Output details:

–color: use colors and other text attributes always
–color=WHEN: use colors and other text attributes if WHEN. WHEN may be ‘always’, ‘never’, ‘auto’, or ‘html’.
–style=STYLEFILE: specify CSS style rule file for –color
–no-escape: do not use C escapes in output (default)
–escape: use C escapes in output, no extended chars
–force-po: write PO file even if empty
–indent: indented output style
–no-location: suppress ‘#: filename:line’ lines
-n, –add-location: preserve ‘#: filename:line’ lines (default)
–strict: strict Uniforum output style
-p, –properties-output: write out a Java .properties file
–stringtable-output: write out a NeXTstep/GNUstep .strings file
-w, –width=NUMBER: set output page width
–no-wrap: do not break long message lines, longer than the output page width, into several lines
