cli module based on github.com/urfave/cli

[myzie]

New cli module supports building full-featured CLIs in the Risor language.

Supports:

• Commands and subcommands
• Flags with default values, can be required
• Arguments for commands
• Action functions provided wrapped urfave/cli context

Use this specific shebang line at the start of script files: #!/usr/bin/env risor -- to ensure flags and args are passed through correctly.

Additional small enhancements in this PR:

• Fixed bug with pass-through args in CLI
• Support []string in object.FromGoType
• Allow trailing newline characters when parsing maps and lists
• Improve textmate grammar

#!/usr/bin/env risor --

from cli import app, command as c

app({
    name: "myapp",
    description: "My app description",
    commands: [
        command({
            name: "hello",
            description: "Say hello",
            action: func(ctx) {
                print("Hello, world!")
            },
        }),
    ],
}).run()
