dispipe

Dispipe sends line-based input on named pipes to pre-configured Discord channels. Effectively, it lets you make write-only discord bots using shell script, or any arbitrary language, without needing a library!

Building

Built with rustc 1.45.0, earlier versions may not work. Depends on serenity, nix, and rust-ini packages.

Compile with: $ cargo build --release

You can find the binary at target/release/dispipe

Usage

To start the bot:

$ dispipe /path/to/config.ini

Send a message to a configured Discord channel:

$ echo "hello from dispipe!" > /var/dispipe/example.fifo

Configuration

; Config Structure
; 1. The 'Dispipe' section is mandatory, it specifies the root directory and discord bot token
; 2. All other sections are optional "fifo configs" that specify a fifo name and channel ID

; Example:

[Dispipe]                       ; Mandatory config section
token = ...                     ; Discord bot token
root = /var/dispipe             ; Directory containing FIFO files

                                ; Example "fifo config" section
[Example]                       ; Title used for easy identification (echoed to stdout with message)
fifo = example.fifo             ; Name of the fifo file to listen on
channel = 99999999999999999     ; Channel ID to send messages to

; ...                           ; Any number of additional fifo configs can be created

Notes

Pre-Requisites

You must register a bot with discord, retrieve a token, and invite the bot to a server. The server must also allow your bot the write messages permission.

Usage

• Messages are sent when a newline character '\n' is encountered on the configured FIFO.
• Lines longer than 2000 bytes will be truncated, 2000 bytes is the discord message limit.
• You can safely write to the FIFO from multiple processes.
