Re: [Factor-talk] command-line.parser but with commands?

[Zoltán K. <zo...@pr...>]

I believe you are looking for something like this unless I am mistaken:

USING: combinators command-line io kernel namespaces sequences ;
IN: foo

! Help text
: help ( -- )
    "Usage: foo [command]" print
    "Available commands:" print
    "  greet   - Print a greeting" print
    "  help    - Show this message" print ;

! Command: greet
: greet ( -- )
    "Hello from Factor!" print ;

! Dispatch function: handles command and its arguments
: dispatch ( cmd rest -- )
    {
        { "greet" [ drop greet ] }
        { "help"  [ drop help ] }
        [ drop "Unknown command: " swap append print help ]
    } case ;

! Entry point
: run ( -- )
    command-line get dup empty? [
        drop help
    ] [
        dup rest swap first dispatch
    ] if ;

MAIN: run

You can extend it to your liking.
