7.2.1 Defining a parser

Some functions are called and set automatically when you call ‘cpt-lib’, so you shouldn’t define the option parser after calling the library, as some of the variables will already be set.

If the function ‘parser_definition()’ as defined when ‘cpt-lib’ is called, cpt-lib will handle the option parsing itself by calling ‘getoptions’ inside. Here is the proper way of doing it.

#!/bin/sh -e

parser_definition() {
    # The rest arguments MUST be defined as 'REST'
    setup REST help:usage                  -- "usage: ${0##*/} [options] [pkg...]"
    msg                                    -- '' 'Options:'
    flag CPT_TEST -t export:1 init:@export -- "Enable tests"

    global_options
}
