Base64.decode ERROR [SOLVED]

General
1

Hello, i don’t understand where is the problem with Base64.decode function…

This is my Main tab :


callback = function()
    GithubLoader.import_file("HyroVitalyProtago", "AllFighters-Codea-Project", "Tools/XML.lua", function()
        sound(SOUND_PICKUP, 11797)
        print(XML)
    end, nil, true)
end
http.request("https://dl.dropboxusercontent.com/s/86ilsm4r8zf3d9s/GithubLoader.private.lua.txt?token_hash=AAEmvJEG_og219e_7ue-_nq_nrj-qnHOyWeIan4Zj4BXKA&dl=1", function(data)
    assert(loadstring(data))()
    setup()
end, alert)

Thanks before !

@Briarfox ? @Bortels ? An idea ?

@HyroVitalyProtago I’m not even seeing a Base64 call?

when i run the setup, i download dkjson and base64.

Function used is GithubLoader.import_file

Sorry should have realized that, I already had the tab pulled into a project. I’ll look at it after work today. I haven’t played with Base64 that much. I’ve only used to to setup oauth in my autogist.

Ok, part of problem is github save "
", but now, when i remove "
" with gsub, loadstring return an error at line 81 'then' expected near '='

Original code line 81 :
if i ~= nil and i == 1 then

Code downloaded and remake with base64 :
if i = nil and i == 1 then

The character ~ disappear for one reason that i ignore…

Reason : base64 of github use + and not - in Base64.lua

When use github api, don’t forget about Base64.decode(contentGetWithApi:gsub("\ ", ""):gsub("+", "-"))
