API Transforms w/ Options

[joshlasdin]

How do I specify options for transforms (using more than 1) using the API syntax? Saw this thread: #39 but I can't find a way to pass options to the transform.

Thanks!

Maybe I'm misunderstanding this block, but according to node-browserify b.transform() accepts two properties in the order of name, options. Other projects like grunt-browserify allow an array of transforms which can each have settings defined (in [name, options]) format. Wondering if that same mentality could be applied here, changing:

if (opts.transform) {
    [].concat(opts.transform).forEach(function (t) {
        if (typeof t === 'string') {
            b.transform({}, t);
        } else {
            b.transform(t, t._.shift());
        }
    });
}

to:

if (opts.transform) {
    [].concat(opts.transform).forEach(function (t) {
        if (typeof t === 'string') {
            b.transform(t, {});
        } else {
            b.transform(t[0], t[1]);
        }
    });
}

(example options definition):

{
    transform: [
        ['hbsfy', { global: true }],
        ['debowerify', { global: true }]
    ]
}

Of course, I may just be totally misunderstanding this block, but this change appears to work in the way I thought the API option would be used.

You can specify multiple transforms by using --transform multiple times. To pass arguments to the transforms, you have to use the subarg notation:

$ mochify --transform [ mything -x -y -z ]

Does that answer your question?

@mantoni Actually I was referring to using the module API, the example given in the README was:

var mochify = require('mochify');

mochify('./test/*.js', {
    reporter : 'tap',
    cover    : true
}).bundle();

Thanks!

Ah, I see. Well, then you will have to look into the browserify API documentation. Mochify returns a Browserify instance. So this is what the API is like:

b.transform(tr, opts={})

[joshlasdin]

Ah, I didn't realize that it returned a browserify instance, moved my transforms to just use the browserify api directly and that works great. Thanks!

I've been looking for an example of passing arguments to "hbsfy" transform via subarg syntax. Finally got it working and posting for others in case they're searching.

I want to pass in these arguments:

hbsfy --compiler 'require("handlebars")'

(Reason for this is that I can't use the hbsfy/runtime because I need to dynamically register partials).

The subarg syntax to do this is:

    b = mochify(config.tests.testFiles, {
      transform: { _: [ 'hbsfy' ], compiler: 'require("handlebars")' },
    })
