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
|
|
|
|
--delete --id ID_1,ID_2 --id ID_3 langfile
|
|
|
|
Delete a number of ids. THIS WILL BREAK BACKWARDS COMPATIBILITY. Use with
|
|
extreme caution.
|
|
Example: langtool --delete --id LANG_LEFT,LANG_RIGHT english.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
