# someday/maybe

- being able to add types: i.e. a validator (easy to do, just haven't exposed)
- Maybe this later: var opts = parser.parse({argv: process.argv});


# notes: supporting opts from env or from a file

Say I have a 'foo' tool with a '-v' option for verbose. I also want
FOO_VERBOSE envvar to set verbose:

    $ foo -v
    debug: blah blah
    ...

    $ FOO_VERBOSE=1 foo
    debug: blah blah
    ...

foo.js:

    var dashdash = require('dashdash')
    var options = [{name: 'v', env: 'FOO_VERBOSE', type: 'bool'}];
    var parser = new dashdash.Parser({options: options});
    var opts = parser.parse(process.argv);

Say, also a ~/.foorc file is supported (somewhat a la ~/.ackrc) where
the file holds extra CLI opts:

    $ cat ~/.foorc
    -v -i
    --file=foo.txt

Parsing that would look like:

    var options = [
        {name: 'v', env: 'FOO_VERBOSE', type: 'bool'},
        {name: 'i', type: 'bool'},
        {name: 'file', env: 'FOO_FILE', type: 'string'}
    ];
    var parser = new dashdash.Parser({options: options});
    var opts = parser.parse(process.argv);
