This is an old revision of the document!

Just a Braindump for various useful things, mostly concerning Programming Languages!

Python & gettext on Windows

First Time Run:

perl gettext\bin\intltool-extract --type=gettext/glae hit_gui.glade
gettext\bin\xgettext.exe --language=Python --keyword=_ --keyword=N_ --output=hit.pot hit_gui.glade.h hit.py
gettext\bin\msginit --input=hit.pot --locale=de_DE
gettext\bin\msginit --input=hit.pot --locale=it_IT
md locale
md locale\de_DE
md locale\de_DE\LC_MESSAGES
md locale\it_IT
md locale\it_IT\LC_MESSAGES

*** Create Translation in de.po/it.po/... ***

gettext\bin\msgfmt --output-file=locale\de_DE\LC_MESSAGES\hit.mo de.po
gettext\bin\msgfmt --output-file=locale\it_IT\LC_MESSAGES\hit.mo it.po

Code Change:
perl gettext\bin\intltool-extract --type=gettext/glade hit_gui.glade
gettext\bin\xgettext.exe --language=Python --keyword=_ --keyword=N_ --output=hit.pot hit_gui.glade.h hit.py
gettext\bin\msgmerge -U de.po hit.pot
gettext\bin\msgmerge -U it.po hit.pot

*** Create Translation in de.po/it.po/... ***

gettext\bin\msgfmt --output-file=locale\de_DE\LC_MESSAGES\hit.mo de.po
gettext\bin\msgfmt --output-file=locale\it_IT\LC_MESSAGES\hit.mo it.po

To avoid problems with UTF8 and ISO conversions, I usually run the program via a batch file, setting the language explicitly (set lang=de_DE).
