Gomphotherium is a command line Mastodon client.
The software provides a CLI as well as a TUI with a usage similar to rainbowstream. It is intended to be used at 80 characters width maximum, but ideally inside tmux as a sidebar-style program.
The CLI interface allows for execution of commands right from the terminal prompt. Not all commands are supported.
The TUI can be operated in two modes: Normal and Command.
- Normal mode – no interaction is possible apart from scrolling and refreshing the timeline and quitting Gomphotherium.
- Command mode – the command input becomes available and scrolling the timeline is not possible anymore. Commands can then be issued to interact with the Mastodon instance.
This is free and open source software.
