Option parser for bash scripts

Bash (long) option parser

Simple argument parser for --long-options. Nothing else, no usage and no -s -h -o -r -t

It does however support values that are empty or begin with --

Example

$ cat example
#!/usr/bin/env bash
source parse_options

options[foo]="foo default"
options_flags=('verbose')
parse_options "$@"

for k in "${!options[@]}"; do
  echo "$k:${options[$k]}"
done

$ ./example --verbose --bar --bar-value --empty-option ''
verbose:on
bar:--bar-value
foo:foo default
empty-option:

Settings

The settings are provided through shell variables

options

Associative array of default values, declared when sourcing the script. This is also where the parsed result is stored.

options[some-option]="some value"

options_flags

Array of options to be interpreted as flags, i.e. that have no value

options_flags=('debug' 'enable-foo')

options_force

If set to 'yes', returns error on unknown options

options_force='yes'
