gettextExample
🔗Name
gettextExample.lua - darktable script to show how translations works
🔗Description
To create the .po file run: xgettext -l lua gettextExample.lua
xgettext is not a lua tool, it knows (almost) nothing about Lua, and not enough to do a proper parsing. It takes a text file (In our case a Lua file) and recognises a few (language dependant) keyword in there. It matches those keywords with internal description on how functions are called and creates the .po file accordingly. (For example, it knows that the first argument of gettext() is the translated string, but that it’s the second argument for dgettext) This is important because it means that if you use some neat Lua tricks (like renaming functions) xgettext won’t recognize those calls and won’t extract the string to the .po file. So, this is why we create a local variagle gettext = dt.gettext, so xgettext recognises gettext.gettext as a function but not dt.gettext.gettext
To create a .mo file run:
msgfmt -v gettextExample.po -o gettextExample.mo
🔗Usage
- start this script from script manager
- copy the gettextExample.mo to .config/darktable/lua/de_DE/LC_MESSAGES
You need to start darktable with the Lua debug option: darktable -d lua $LANG must set to: de_DE
The script run on darktable startup and should output this three lines:
LUA ERROR Hello World!
LUA ERROR Bild
LUA ERROR Hallo Welt!
