Utility module to simplify initializing locals from tables or modules.
local debug = require 'debug'
-- from.lua
-- supports some useful shortcuts when creating locals from tables or modules
-- require 'from'
-- local sin,cos,tan = slots(3) from(math)
-- local import,printf = slots(2) from 'pl.utils'
-- local pretty,utils,xml = slots(3) from 'pl.*'
--
-- Uses the debug library, so it's not very fast - only use for top-level initialization!

print('end',sa[-1])

stevedonovan / safe_array.lua
Created December 30, 2010 08:20
This defines an array with strict bounds checking. It is also impossible to set any existing index to a nil value, so the array remains free of holes. The table functions will not work on such arrays because they are userdata, giving an extra layer of pro
local function out_of_range(i,n)
if type(i) == 'number' then
if i > 0 and i <= n then return true
else error('out of range',3)
end
else
error 'cannot index array by non-number type'
end

Created March 28, 2011 07:04
An interactive Lua prompt for the Textadept editor
-- makes interactive prompt dodgy.
-- (In an ideal world, should be able to switch this off only for
-- the message buffer)
_m.textadept.editing.AUTOPAIR = false
-- useful function which can safely handle argument lists containing nil;
-- the resulting table has n set to the real length.
local function pack (...)
local args = {...}
args.n = select('#',...)
