administration.lua
Version 1.10
Part of the otouto project.
© 2016 topkecleon <drew@otou.to>
GNU General Public License, version 2
This plugin provides self-hosted, single-realm group administration.
It requires tg (http://github.com/vysheng/tg) with supergroup support.
For more documentation, read the the manual (otou.to/rtfm).
Remember to load this before blacklist.lua.
Important notices about updates will be here!
1.9 - Added flag antihammer. Groups with antihammer enabled will not be
affected by global bans. However, users who are hammer'd from an anti-
hammer group will also be banned locally. Added autobanning after (default)
3 autokicks. Threshold onfigurable with antiflood. Autokick counters reset
within twenty-four hours. Merged antisquig action into generic. There is no
automatic migration; simply add the following to database.administration:
autokick_timer = 0
groups[*].flags[6] = false
groups[*].autoban = 3
groups[*].autokicks = {}b
1.9.1 - Returned to non-toggled promotions/bans (too many complaints!).
1.10 - Added /ahelp $command support. No migration required. All actions
have been reworked to be more elegant. Style has been slightly changed (no
more weak-looking, italic group names). Added some (but not many) comments.
1.10.1 - Bug fixes and minor improvements. :^)
1.10.2 - Fixed bug in antibot. Further, ranks 2+ will be automatically made
group admins when they join a group.
1.10.3 - /gadd now supports arguments to enable flags immediately, eg:
"/gadd 1 4 5" will add a grouo with the unlisted, antibot, and antiflood
flags.
