On Behalf Of Leinen, Rick Greetings, I’ve been reading chapter 29 of Programming in Lua 3ed. I understand everything from the beginning of the chapter through 29.1 except for one thing. How does Lua get the function name “array”? I understand how the library array works
for registering the functions “new”, “set”, etc, but when the text shows the line “a = array.new(1000), how does the label “array” get associated with the library? I’m sure there must be a simple answer, it’s just alluding me. Thanks, Rick Thanks to Doug Currie for clearing this up for me! I’m still working on proof-of-concept on my project and currently do not have a file system in place on my target. Registering the new library worked just fine, but when I enter, array = require "arraylib",
from my shell interface I get the following response: [string "array = require "arraylib""]:1: module 'arraylib' not found: no field package.preload['arraylib'] no file '/usr/local/share/lua/5.2/arraylib.lua' no file '/usr/local/share/lua/5.2/arraylib/init.lua' no file '/usr/local/lib/lua/5.2/arraylib.lua' no file '/usr/local/lib/lua/5.2/arraylib/init.lua' no file './arraylib.lua' no file '/usr/local/lib/lua/5.2/arraylib.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './arraylib.so' Is there a way to use this userdata method without a file system? I got around this problem with my C functions using the following: void LCAN_RegFunctions( lua_State *L ) { lua_pushcfunction(L, LCAN_LuaSendChanFade); lua_setglobal(L, "LCAN_SendChanFade"); lua_pushcfunction(L, LCAN_LuaAddDimmer); lua_setglobal(L, "LCAN_AddDimmer"); } Thanks, Rick |
