GoTermFX

Terminal animations for people who spend too much time in the terminal.

---

GoTermFX is a zero-dependency terminal animation CLI written in Go. Rain, matrix, fireworks, hyperspace, snow — all running directly in your terminal, all cancellable with a single keypress. You can also drop in your own animations with about 10 lines of Go.

Install

go install github.com/mohamedation/gotermfx@latest

Build from source

git clone https://github.com/mohamedation/gotermfx.git
cd gotermfx
make build        # compiles to ./bin/gotermfx
make install      # installs to /usr/local/bin
make uninstall    # removes it

You can also run without installing:

make run                  # runs a random animation
make run ARGS=matrix      # run a specific one

make test    # run unit tests
make cover   # run tests with coverage summary

Usage

gotermfx                  # random animation
gotermfx matrix           # run a specific one
gotermfx -i               # interactive picker
gotermfx -1               # run once then exit
gotermfx -1 -d 5s         # with a max duration for animations with a sequence

Add Your Own

The whole thing is built around a single interface:

type Animation interface {
    Run(ctx context.Context)
}

Create a file in animations/, implement Run, register it in init, and it shows up automatically:

package animations

import (
    "context"
    "gotermfx/termfx"
)

type myAnimation struct{}

func (a *myAnimation) Run(ctx context.Context) {
    for {
        select {
        case <-ctx.Done():
            return
        default:
            // draw something
        }
    }
}

func init() {
    termfx.Register("MyAnimation", &myAnimation{})
}
