Can we get these basic functions added so we are not always having to copy them around?
Adding print_r would be helpful too (call it table.print if that makes more sense)

In the beginning of your code you could use
[lua]local url = require(“socket.url”)[/lua]
Then you have access to url.escape() and url.unescape() and some other goodies.

I did not know that… [import]uid: 19626 topic_id: 20355 reply_id: 79603[/import]
I didn’t know about “socket.url” either until a few months ago when I happened to stumble upon the LUA article I posted above…
For print_r() I found this code (haven’t used it myself yet though):
[lua]-- example usage:
– require ‘print_r’
– a = {x=1, y=2, label={text=‘hans’, color=‘blue’}, list={‘a’,‘b’,‘c’}}
– pr(a, ‘My table’)
–My table = {
–| y = 2
–| x = 1
–| list = {
–| | [1] = “a”
–| | [2] = “b”
–| | [3] = “c”
–| }
–| label = {
–| | color = “blue”
–| | text = “hans”
–| }
–}
