Lua support (#878) * Test implementation of lua * Trust that lua knows what its doing with this Silence warnings * actually update top screen when Thingy is called, disable unnecessary ShowPrompt calls * readme * change init for a simple test, print error on top screen too * Readme * change init for a simple test, print error on top screen too * enable more lua libs, edit init.lua with string examples * one more readme edit before bed * Readme * change init for a simple test, print error on top screen too * enable more lua libs, edit init.lua with string examples * make lua a proper file type, add test UI library with two functions, remove luacmd command * remove old attempts at editing lauxlib and liolib * README * README * FS lib, new UI stuff * consistency with "type* ptr" maybe * add custom package searcher, reset package.path * new functions for UI including basic print output buffer, add "Lua scripts..." option to home/power menu * build vram0.tar including subdirs of data * move default path to GM9LUA_DEFAULT_PATH * FS_FileGetData * testfgd, add GM9VERSION global, update README, fix indentation * FS_FileGetData will return a nil instead if it fails * it's actually luaL_pushfail * os * use luaL_tolstring instead of lua_tostring * fix test/remove debugging showprompt * os.clock float attempt * fix print for real * fix swapped offset and size for FileGetData * finish OS stuff * fix os.clock * shorten table in/out * remove .vscode dir * enum test * support building without lua * NO_LUA hides menu options (except when you directly select a lua file) * update UI lib to better match the ideas on #1 * dockermake * add DrawPNG function * whoops its ShowPNG * minor fixes, add DrawPNG * fix AskPrompt, add all showprompts mentioned in #1 * add newly added functions to readme * try to keep separate code and data * update lua to 5.4.7 * remove test libraries now that i want to attempt to implement in a real api * add nix flake for building * add various lua functions, some of them taken from the old attempt but with new names * add dev shell to flake.nix * remove test lua scripts in root * add test lua scripts in data/luascripts * add a whole bunch more lua functions and stuff * add more test lua scripts * add more functions, add preload script, add test io compatibility module * add more functions and test scripts * more functions and stuff * more functions and stuff * more functions and stuff, plus a wip ctrcheck reimpl * yet more functions and stuff * even more functions and stuff * command comparison table.ods * update command comparison table.ods * update command comparison table.ods * Add files via upload * update command comparison table.ods * update ui.show_text to use DrawStringCenter, update ctrcheck rewrite * Split up the ARM9 code (.text, .vectors) and data (.rodata, .data, .bss) sections into their own ELFs. This allows us to use more ARM9 WRAM while leaving the 128k BootROM mirror intact. * use the makefile definition * add title module, move around some functions, update command comparison table * add readme for lua * remove liolib.c and loslib.c * more functions and things, use CheckWritePermissionsLuaError in place of more manual checks, update command comparison table * add missing constant *
