# This file is intended to replace everything that gettextize or autopoint
|
||
|
|
# installs. It has a lot less weird crud and tries to cooperate with
|
||
|
|
# automake at least a little bit.
|
||
|
|
#
|
||
|
|
# To use it:
|
||
|
|
# - Edit COPYRIGHT_HOLDER and MSGID_BUGS_ADDRESS below
|
||
|
|
#
|
||
|
|
# - Add the file types you're interested in to POTFILE_SUFFIXES. This replaces
|
||
|
|
# the old POTFILES.in since the list of files you want to select for
|
||
|
|
# translation is invariably all of them.
|
||
|
|
#
|
||
|
|
# - If you have other files that can't be selected by suffix, or that need to
|
||
|
|
# be built from source files, add them to POTFILE_EXTRA
|
||
|
|
#
|
||
|
|
# - Add po/Makefile to AC_CONFIG_FILES (there may be po/Makefile.in if
|
||
|
|
# switching from gettextize, replace that)
|
||
|
|
#
|
||
|
|
# - Get rid of AM_GNU_GETTEXT and AM_GNU_GETTEXT_VERSION. You might want to
|
||
|
|
# add checks for xgettext, msgmerge, msgfmt, and msgcat. Up to you.
|
||
|
|
#
|
||
|
|
# - Add the following to .gitignore:
|
||
|
|
# po/*.mo
|
||
|
|
# po/*.po
|
||
|
|
# po/*.mpo
|
||
|
|
# po/*.pot
|
||
|
|
#
|
||
|
|
# - Remove everything in the po/ directory from source control except this
|
||
|
|
# file.
|
||
|
|
#
|
||
|
|
# The idea is something like this:
|
||
|
|
# From a clean project, you do the automake stuff and download a bunch of
|
||
|
|
# .po files from the external translation site. These are the "source" files.
|
||
|
|
#
|
||
|
|
# From the source tree we create a template file, <package>.pot, of all the
|
||
|
|
# translatable strings. This file is not saved or distributed because there's
|
||
|
|
# really no reason to do that if translations are not part of the source
|
||
|
|
# tree. The file is pushed to the translators when creating a new release,
|
||
|
|
# and it is used during the build, and that's it.
|
||
|
|
#
|
||
|
|
# The .po files might not match the .pot file, because this is the nature of
|
||
|
|
# linear time and translations being a separate task. Maybe the translator
|
||
|
|
# last touched the .po file yesterday. Maybe three years ago. To get the
|
||
|
|
# translations in sync with the source, which usually means untranslating
|
||
|
|
# some strings, we run msgmerge on all of the source files. The merged files
|
||
|
|
# are saved in builddir as <lang>.mpo, which is a non-standard file extension
|
||
|
|
# I just made up.
|
||
|
|
#
|
||
|
|
# The merged .po files are then compiled into .mo files, which are what
|
||
|
|
# get installed to /usr/share/locale.
|
||
|
|
|
||
|
|
# Variables used in xgettext arguments
