Command Interface System

|Build status|

|Documentation|

This is a system for building command-driven interfaces in Dylan.

It can currently be used to declaratively design terminal-based command interfaces, commonly called shells or CLIs.

We also strive to implement graphical command interfaces in a similar manner to Symbolics Genera, including support for full graphical and markup output.

Compiling

Update library dependencies:

dylan update

Build the library, tests and demo with:

dylan build --all

Run the demo:

_build/bin/command-interface-demo

And the tests:

_build/bin/command-interface-test

Completion in bash

Our system integrates with bash completion. This allows one to implement a binary that can be used both as an interactive shell and from the system shell.

To enable this feature you need to load the shell snippet printed by the following command into your shell:

_build/bin/command-interface-demo bashcomplete

Once you do this you can complete and execute all commands that would be available inside the shell.

This feature is automatically available to library users.
