Question 1

How do I implement tab completion with Liner in Go?

Accepted Answer

Use the SetCompleter method to define a function that returns completion candidates based on input; the example matches names starting with the typed line, requiring custom logic for your use case.

Question 2

Liner vs readline for Go: which should I use?

Accepted Answer

Liner is pure Go and ensures cross-platform consistency, while readline often relies on C dependencies with more Unix-centric features. Choose Liner for easy compilation and uniform behavior, but readline if you need advanced Unix-specific capabilities.

Question 3

Can Liner save command history between sessions?

Accepted Answer

Yes, but you need to manage it manually using ReadHistory and WriteHistory methods with file handles, as demonstrated in the getting started code; it doesn't auto-save by default.

Question 4

What terminals are compatible with Liner?

Accepted Answer

Liner works on terminals that emulate VT100, including most Unix-like systems, and has specific support for Windows; ensure your terminal pretends to be VT100 for full functionality, as noted in the README.

Question 5

How to customize keybindings in Liner?

Accepted Answer

Liner uses a fixed set of keystrokes listed in the README; customization is limited, and you might need to fork the library or use external packages to alter bindings for specific needs.

Question 6

Is Liner good for building a shell in Go?

Accepted Answer

Yes, for basic shells requiring line editing with history and completion, but it lacks built-in support for job control or complex parsing, so you'll need to handle those aspects separately.
