Lemmy Reply Bot
This project is a simple bot that replies to comments and posts on Lemmy. It gets the newest posts and comments every configurable interval, and sees if they match any regex configured in the config file. If it finds one that does, it replies with the message corresponding to that regex.
Features
- Multiple replies in a single bot instance
- Powerful PCRE2 regular expressions for detecting triggers
- Ability to use regex capture groups in replies
- Persistent duplicate reply prevention via a filesystem store
- Powerful templates via Salix
Configuration
This repo contains a file called lemmy-reply-bot.example.toml
. This is an example config file. You can edit it to fit your needs. The config contains your password, so its permissions must be set to 600 or the bot will refuse to start.
This bot uses my Pure-Go PCRE2 port for regular expressions, so you can use any of PCRE2's features, and Regex101 in PCRE2 mode for testing.
If any regular expressions configured in the file also match the reply messages, the bot will refuse to start because this may cause an infinite loop.
Debugging
In order to enable debug log messages, set LEMMY_REPLY_BOT_DEBUG=1
.
Building and Running
First, make sure Go 1.18 or newer is installed on your system. Older versions will not work.
If you are planning to run it on the same machine as the one you're building on, simply run
go build
And then you can start the bot with
./lemmy-reply-bot
If you want to run it on a different machine than the one you're building on, for example, a Raspberry Pi, you can build it like this:
GOARCH=arm64 go build
If your raspberry pi is 32-bit, use arm
instead of arm64
. Then, you can run it the same way I described above.
