(API Change) Refactor module handling Changed API: - char *obs_find_plugin_file(const char *sub_path); Changed to: char *obs_module_file(const char *file); Cahnge it so you no longer need to specify a sub-path such as: obs_find_plugin_file("module_name/file.ext") Instead, now automatically handle the module data path so all you need to do is: obs_module_file("file.ext") - int obs_load_module(const char *name); Changed to: int obs_open_module(obs_module_t *module, const char *path, const char *data_path); bool obs_init_module(obs_module_t module); Change the module loading API so that if the front-end chooses, it can load modules directly from a specified path, and associate a data directory with it on the spot. The module will not be initialized immediately; obs_init_module must be called on the module pointer in order to fully initialize the module. This is done so a module can be disabled by the front-end if the it so chooses. New API: - void obs_add_module_path(const char *bin, const char *data); These functions allow you to specify new module search paths to add, and allow you to search through them, or optionally just load all modules from them. If the string %module% is included, it will replace it with the module's name when that string is used as a lookup. Data paths are now directly added to the module's internal storage structure, and when obs_find_module_file is used, it will look up the pointer to the obs_module structure and get its data directory that way. Example: obs_add_module_path("/opt/obs/my-modules/%module%/bin", "/opt/obs/my-modules/%module%/data"); This would cause it to additionally look for the binary of a hypthetical module named "foo" at /opt/obs/my-modules/foo/bin/foo.so (or libfoo.so), and then look for the data in /opt/obs/my-modules/foo/data. This gives the front-end more flexibility for handling third-party plugin modules, or handling all plugin modules in a custom way. - void obs_find_modules(obs_find_module_callback_t callback, void *param); This searches the existing paths for modules and calls the callback function when any are found. Useful for plugin management and custom handling of the paths by the front-end if desired. - void obs_load_all_modules(void); Search through the paths and both loads and initializes all modules automatically without custom handling. - void obs_enum_modules(obs_enum_module_callback_t callback, void *param); Enumerates currently opened modules.
