pocheck.pl [-acmpqst] po_file [po_file] ...
|
|
|
|
This script performs some consistency checks on po files.
|
|
|
|
We check for everything listed here, unless one or more of these
|
|
options is given, in which case we checks only for those requested.
|
|
-a: Check arguments, like %1\$s
|
|
-c: Check for colons at end
|
|
-m: Check for menu shortcuts
|
|
-p: Check for period at end
|
|
-q: Check Qt shortcuts
|
|
-s: Check for space at end
|
|
-t: Check for uniform translation
|
|
These options can be given with or without other options.
|
|
-f: Ignore fuzzy translations
|
|
-w: Only report summary total of errors
|
|
-i: Silent mode, report only errors
|
