Hello,
In Lua 5.1 I am doing this to populate keyword_table from global variables
defined in sc.synthdefsc.
This file, after defining some globals has requires to other files (say
require"blabla")
from which I also want to get global variables and that need the definitions
contained sc.synthdefsc.
---------------sc,synthdef.lua
variable = 1234
require"blabla"
more_things
--------------blabla
variable2 = variable *3
------------------------
If I dont do require"sc.synthdefsc" ( which is polluting _G)
then "blabla" is not getting variable=1234. That means that cant get it form
env
and looks in _G instead.
This is the code:
local env = {}
local keyword_table = {}
require"sc.synthdefsc"
local f = assert(loadfile(_scscriptsdir.."synthdefsc.lua"))
setfenv(f, setmetatable(env, {__index = _G}))
f()
for index, value in pairs(env) do
-- put in keyword_table
Is there any way to avoid polluting _G (which has bad side effects for me)
by using require"sc.synthdefsc"
Best
