Those of you familiar with bash's select builtin know that the automated layout of choices is a nice feature. Last week while prototyping some SQL I became frustrated with select, mostly because you must type in a number and then press the Enter key. Remembering the TUI interfaces of the 1980's, I set about writing hkselect, a hotkey driven replacement for select. Here are the main features:

  • Automated layout of choices.
  • Assign item hotkey with &.
  • Automatic hotkey assignment if & is missing.
  • Bind escaped keys to callback functions.
  • Transparently caches layout information and composed labels.

Full project is here

Below is an example bash program with a functioning hotkey TUI that includes callbacks for F1, F2, and F3:
