From 7cd218b920814322d002f915ed5c8bb0132cf40a Mon Sep 17 00:00:00 2001 From: Philipp Gesang Date: Thu, 27 Aug 2015 23:28:32 +0200 Subject: [main,loaders] regroup callback handling code with loaders MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ... changing the meaning of the file’s designation instead of adding yet another file. All the callback manipulation is now contained inside that module which will inject most of its functionality only when its main ``.install()`` method is called. --- src/luaotfload-main.lua | 116 ++++++------------------------------------------ 1 file changed, 14 insertions(+), 102 deletions(-) (limited to 'src/luaotfload-main.lua') diff --git a/src/luaotfload-main.lua b/src/luaotfload-main.lua index 36db2c3..fe27215 100644 --- a/src/luaotfload-main.lua +++ b/src/luaotfload-main.lua @@ -67,12 +67,6 @@ luaotfload.module = { local luatexbase = luatexbase local require = require local type = type -local add_to_callback = luatexbase.add_to_callback -local create_callback = luatexbase.create_callback -local reset_callback = luatexbase.reset_callback -local call_callback = luatexbase.call_callback - -local dummy_function = function () end --- XXX this will be moved to the luaotfload namespace when we have the init module local error, warning, info, log = luatexbase.provides_module(luaotfload.module) @@ -165,110 +159,28 @@ end luaotfload.init.main (store) -load_luaotfload_module "loaders" --- Type1 font wrappers -load_luaotfload_module "database" --- Font management. -load_luaotfload_module "colors" --- Per-font colors. - -luaotfload.resolvers = load_luaotfload_module "resolvers" --- Font lookup - -luaotfload.resolvers.install () - -if not config.actions.reconfigure () then - logreport ("log", 0, "load", "Post-configuration hooks failed.") -end - ---[[doc-- - - We create callbacks for patching fonts on the fly, to be used by - other packages.
