A command line utility written in Go to display guitar fretboard, scales and chords in any tuning.
Because I love Go, CLIs and guitar (and Hendrix obviously!)
Try Jimi in your browser with a live demo made with WebAssembly.
Jimi does not require any specific package or dependency and can be compiled on Linux, macOS or Windows.
If you do not have Go installed yet, you know what to do.
Just git clone this repo and run go build in a terminal from the root directory.
Note for Windows users: The Windows Console may not output colored characters properly. You may use PowerShell instead.
Standard tuning and no capo.
