File extension not supported

jescalan commented 10 years ago

Perhaps I'm doing something wrong here -- I'm trying to use a gulp plugin to compile jade, but alas duo is telling me that this file type is not supported.

The folder structure of the project:

.
├── app.coffee
├── index.jade
└── package.json

Code in app.coffee, which is the point from which I'm running duo:

Duo    = require 'duo'
gulp   = require 'duo-gulp'
accord = require 'gulp-accord'

duo = Duo(__dirname)
  .entry('index.jade')
  .use(gulp(accord)('jade'))

duo.run (err, src) ->
  if err then return console.error(err.stack)
  console.log src

The jade file is just a generic hello world, and package.json also generic with just the packages referenced above installed. When I execute app.coffee, I get this error back:

Error: index.jade: ".jade" not supported

Halp!

So Duo needs to know that the file type has changed. When you compile index.jade, it will need to become index.js in order for Duo to continue building.

duo-gulp changes the file type here: https://github.com/duojs/gulp/blob/master/index.js#L43 and it's based on File.path object in gulp.

I have a feeling the plugin doesn't update the file path, so Duo has no way of knowing that it's now working with JS.

Yeah I don't think it does change the file path. This is something that has to be done in the gulp plugin? Also this will compile it to .html not .js - does that matter?

duojs / gulp
