lambdabot-zulip

A lambdabot-like bot for Zulip.

Can evaluate Haskell expressions and show their types.

Usage

Run the lambdabot-zulip-server executable to start the bot.

It reads a settings.yaml in the working directory (or passed via command line).

See [example-settings/settings.yaml](example-settings/settings.yaml) for an example. You have to provide Zulip API credentials, and streams (channels) the bot should be active on.

Systemd unit

For the simple case that you want to run this in a small throwaway VM server as root, here's a systemd unit file.

It assumes that you have the repo cloned at /root/lamdabot-zulip and did stack build in there.

Put this into /etc/systemd/system/lambdabot-zulip-server.service:

[Unit]
Description=Lambdabot Zulip server
After=syslog.target network.target
StartLimitIntervalSec=0

[Service]
ExecStart=/usr/local/bin/stack "exec" "lamdabot-zulip-server"
WorkingDirectory=/root/lambdabot-zulip
Restart=always
Environment="HOME=/root"
MemoryMax=1G

[Install]
WantedBy=multi-user.target

Note that you can't ExecStart the executable directly due to https://github.com/gwern/mueval/issues/16#issuecomment-448707773.

To load the service and have it start at boot:

systemctl daemon-reload
systemctl enable lambdabot-zulip-server
systemctl start lambdabot-zulip-server
