(He)XChat Python script manager replacement

README.md

Pyld

This script replaces the broken Python script manager of HexChat. Just drop it in the "addons" folder and move all other Python scripts to another folder. Replace the basedir variable in this script with the absolute path to your folder and restart.
The script will create a file named auto.txt to store a list of scripts loaded at startup too.

For unloading/reloading to work properly, you need to add a list named hooks inside your scripts and append the return values of the hook functions to it, like this:

hooks = []
(...)
hooks.append(xchat.hook_command("", myfunc))

Commands

• /pyld help
• /pyld list (displays a list of all loaded scripts)
• /pyld load NAME (imports a script from the basedir)
• /pyld unload NAME (unhooks the specified script)
• /pyld reload NAME (do both)
• /pyld auto NAME (add/remove the specified script to the autorun list)
