NAME

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
--sort-output: generate sorted output
--sort-by-file: sort output by file location
