This Doomsday plugin performs the task of translating dehacked_patches into Doomsday-native ded definitions.
While most dehacked_patch features are available, any unsupported features are detected and will result in warnings being logged (and if enabled, alerts).
Say you have the dehacked_patch infiniteammo.deh in your runtime_directory, it can be loaded with the -deh (command_line_option) when first launching a game_session during startup:
Lumps named DEHACKED in .wad files will be automatically applied when the .wad itself is loaded.
Normally only the last DEHACKED lump loaded will be applied when two or more lumps with that name are found (perhaps in multiple .wad files). However, the -alldehs (command_line_option) can be used to instruct Doomsday to apply them all, in the order in which they are found.
