Usage langtool [--inplace] --options langfile1 [langfile2 ...]
For all actions, the modified langfile will be output on stdout. When doing
stuff to english.lang, you should almost always apply the same change to all
other languages to avoid bothering translators.
--deprecate --id ID_1,ID_2 --id ID_3 langfile
Deprecate a number of ids.
Example: langtool --id LANG_LEFT,LANG_RIGHT --LANG_BOTTOM english.lang
--changesource --id ID --target target --to string langfile
Change the source text of a specific string specified by id and target. Use
this on all langfiles if you're changing a source in english.lang that
doesn't need attention from translators (case changes etc.).
Example:
langtool --changesource --id LANG_OK --target e200 --to "OK" english.lang
--changeid --from LANG_LFET --to LANG_LEFT langfile
Change the name of an ID. THIS WILL BREAK BACKWARDS COMPATIBILITY. Use with
extreme caution.
Example: langtool --changeid --from LANG_OK --to LANG_YES english.lang
--changedesc --to string --id LANG_LEFT langfile
Change the desc for an ID.
Example: langtool --changedesc --to "New desc" --id LANG_OK english.lang
--changetarget --from target --to target --id ID1 langfile
Change the target for the specified id from one value to another
Example:
langtool --changetarget --from e200 --to e200,c200 --id LANG_ON dansk.lang
--inplace
Perform file operations in-place, instead of outputting the result to
stdout. With this option set, you can specify multiple langfiles for
all commands.
Example: langtool --deprecate --id LANG_ASK --inplace *.lang
