Add some convenience functions to plugin API

[TingPing]

Currently you must loop through lists (which is very slow to create in Python) of all users and all channels to find out basic information like a single users account. Perl already has these (userinfo, contextinfo) and it would be useful to add them to the API itself for Python and JavaScript to use.

• hexchat_get_userinfo()
• hexchat_get_contextinfo() (perhaps hexchat_get_chanopt() ?)
• hexchat_get_networkinfo() (after that is completed)

Another common thing to do is get the calculated color of a nick in a script so adding a function to call _text_colorof() for us could be useful.

[nitori]

hexchat.nicklower or hexchat.nickupper, to convert nicknames and channel names to upper/lower case (according to the rfc just like hexchat.nickcmp does), so you can use nicknames and/or channel names as keys for e.g. python/javascript dictionaries. That way you don't have to iterate over the whole dictionary to find the entry or it's existence.

+1 for the ability to get the color of a nickname

Apparently, the algorithm for nick color is as follows (pasted in IRC by TingPing):

colors = (19, 20, 22, 24, 25, 26, 27, 28, 29)

def color_of (nick):
    total = sum(ord(char) for char in nick)
    total %= len(colors)
    return colors[total]

color_of('TingPing')
29
