All The Opts

Wouldn't it be nice if didn't have to use getopt anymore? Well this still a work in progress so come back later and maybe your wish will come true...

pure-getopt which is designed to make GNU getopt's features available everywhere.

This is a wrapper to make it super easy to parse switches.

• validates the inputs
• auto-generate --help message
• simple access to switch values
• context aware arguments

Glossary

TODO: Write a glossary of terms

• option
• option_argument
• operand
• context
• optional_argument
• required_argument
• no_argument

Functionality

• ato_add: context, short, long, description (without last three, show). The order that you add is the order that it is evaluated.
• ato_context: show set contexts or add a context
• ato_description: set or show the description
• ato_help: generate a help message
• ato_operands: the things that are not arguments (what's the real name?)
• ato_read: should read the option argument
• ato_setup: do this first
• ato_options: a list of the 'true' options

A Usage Example

    #!/usr/bin/env bash
    source ./all-the-opts.inc

    ato_description          "this is an example application"
    ato_context_add          "global"

    ato_add n name    "Set your name"
    ato_add v version "Display the version information"

    ato_setup $@

    ato_set --name "the default value of name"

    function version() {
        echo "version 1.0.0"
        return 0
    }

    function name() {
        name="$(ato_value --name)"
        echo "my name is ${name}"
        return 0
    }

    for arg in ${ato_options}; do
        case $arg in
            "-n"|"--name")
                ato_set --name $(ato_value ${arg})
                name
            ;;
            "-v"|"--version") version ;;
        esac
    done
