Redesign AudioProviderFactory Register functions which create each type of provider rather than the provider types themselves so that the concrete types don't need to be publicly exposed, and use a static list of providers rather than registering them at runtime.

#include "include/aegisub/audio_provider.h"
Replace all uses of lagi_wxString with to_wx

Improve audio open error reporting and remove a pile of unused stuff in AudioPlayer Originally committed to SVN as r6223.

#include "audio_controller.h"
Merge all changes from the libaegisub branch into trunk, the effective range is r4175:4330. All options have been re-done and now use Cajun to support a json-backed format. Initial support for low-level access and file I/O methods are included as well. Originally committed to SVN as r4331.
2010-05-21 03:13:36 +02:00
#include "compat.h"
Extract options and MRU stuff from main.h Nearly all of the files including main.h are doing so only for OPT_GET and friends, which are rather unrelated to the main things that main.h declares.

Mostly purge wxWidgets from non-UI stuff Use boost::filesystem::path for all paths, and std::string for all other strings, converting to/from wxString as close to the actual uses of wx as possible. Where possible, replace the uses of non-UI wxWidgets functionality with the additions to the standard library in C++11, or the equivalents in boost. Move the path token management logic to libaegisub (and rewrite it in the process). Add a basic thread pool based on asio and std::thread to libaegisub. This touches nearly every file in the project and a nontrivial amount of code had to be rewritten entirely, so there's probably a lot of broken stuff.
