# Scripts for managing PPFI channels on PirateIRC

The original list of channels comes from where `MI1` is according to oper
`WHOIS` and should match `kanavat.csv` with exceptions of secret channels
and those not (fully) belonging to Pirate Party of Finland.

The scripts only generate lines that should be copy-pasted to a IRC client
for anything to actually happen. They are provided [missing GroupServ](https://github.com/ergochat/ergo/issues/465)
in hope that PPFI is able to operate IRC without @Mikaela constantly present.

* `./generate-amode-cmds.bash +o MI1` - giving user `MI1` op on all channels
  which will persist and be granted on join. ***Prefer this script.***
* `./generate-oper-override-mode.bash +o MI1` - the same, except requires operator
  permission, allows unregistered accounts and doesn't persist over `/cycle`
  whether manual or connection loss or similar. ***Use only in emergency
  and even in emergency, and even then prefer amoding yourself with the previous script and then
  using the next script.***
* `./generate-usual-mode-cmds.bash +o MI1` - non-oper version of the previous script,
  generates normal `/mode` commands within the usual permission system most likely
  requiring being op (use the amode script for that, see drawbacks of the previous script).
