# A note for future users and readers: The original v1 language system allowed
|
|
# the build to create and use a different language than english built-in. We
|
|
# removed that feature from our build-system, but the build scripts still had
|
|
# the ability. But, starting now, this ability is no longer provided since I
|
|
# figured it was boring and unnecessary to write support for now since we

# don't use it anymore.

Usage: genlang [options] <langv2 file>
|
|
|
|
-p=<prefix>
|
|
Make the tool create a [prefix].c and [prefix].h file.
|
|
|
|
-b=<outfile>
|
|
Make the tool create a binary language (.lng) file namaed [outfile].
|
|
The use of this option requires that you also use -e.
|
|
|
|
-u
|
|
Update language file. Given the translated file and the most recent english
|
|
file, you\'ll get an updated version sent to stdout. Suitable action to do
|
|
when you intend to update a translation.
|
|
|
|
-e=<english lang file>
|
|
Point out the english (original source) file, to use that as master
|
|
language template. Used in combination with -b or -u.
|
|
|
|
-t=<target>
|
|
Specify which target you want the translations/phrases for. Required when
|
|
-b or -p is used.
|
|
|
|
The target can in fact be specified as numerous different strings,
|
|
separated with colons. This will make genlang to use all the specified
|
|
strings when searching for a matching phrase.
|
|
|
|
-o
|
|
Voice mode output. Outputs all id: and voice: lines for the given target!
|
|
|
|
-v
|
|
Enables verbose (debug) output.
|

# How update works:
|
|
#
|
|
# 1) scan the english file, keep the whole <phrase> for each phrase.
|
|
# 2) read the translated file, for each end of phrase, compare:
|
|
# A) all source strings, if there's any change there should be a comment about
|
|
# it output
|
|
# B) the desc fields
|
|
#
|
|
# 3) output the phrase with the comments from above
|
|
# 4) check which phrases that the translated version didn't have, and spit out
|
|
# the english version of those
|
|
#
