From ec2737b2c24ac442d2b9fcf0f0222becb456d8ce Mon Sep 17 00:00:00 2001 From: Tom Ross Date: Sun, 18 Oct 2009 00:56:42 +0000 Subject: Change the .lng files to contain strings from multiple users. Still hard-coded to only output the core strings for now. Should be the majority of the core changes needed for translatable plugins. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23241 a1c6a512-1295-4272-9138-f99709370657 --- apps/filetree.c | 2 +- apps/lang/lang.make | 7 ++++- apps/language.c | 78 ++++++++++++++++++++++++++++++++--------------------- apps/language.h | 7 ++++- apps/main.c | 6 +++-- apps/settings.c | 2 +- tools/genlang | 61 ++++++++++++++++++++++++++++------------- 7 files changed, 108 insertions(+), 55 deletions(-) diff --git a/apps/filetree.c b/apps/filetree.c index 8fbc39fa67..3468051b55 100644 --- a/apps/filetree.c +++ b/apps/filetree.c @@ -526,7 +526,7 @@ int ft_enter(struct tree_context* c) case FILE_ATTR_LNG: splash(0, ID2P(LANG_WAIT)); - if(!lang_load(buf)) { + if(!lang_core_load(buf)) { set_file(buf, (char *)global_settings.lang_file, MAX_FILENAME); talk_init(); /* use voice of same language */ diff --git a/apps/lang/lang.make b/apps/lang/lang.make index e32f084a29..f7366c9225 100644 --- a/apps/lang/lang.make +++ b/apps/lang/lang.make @@ -18,9 +18,14 @@ CLEANOBJS += $(BUILDDIR)/lang/max_language_size.h $(BUILDDIR)/lang/lang* # Therefore we create it here. #DUMMY := $(shell mkdir -p $(BUILDDIR)/apps/lang) +# Calculate the maximum language size.
