Move away from Esperanto, as it is deprecated

DEPRECATION NOTICE Esperanto is no longer under active development.

Now what?

[jamesplease]

Rollup

[jamesplease]

hmmm..maybe actually need to use Babel instead. Not sure if Rollup does any format conversion.

[jamesplease]

Rollup's API is, perhaps unsurprisingly, very similar to Esperanto's. And until Babel can inline all dependencies I think I'll need to continue relying on outside dependencies to do this. shucks!

[kristianmandrup]

Yeah, WTF!? :O

22:52 $ npm test

I have all my tests in test/*.test.js with this gulpfile config as provided by https://github.com/babel/generator-babel-boilerplate, modified a tiny bit:

var testFiles = glob.sync('./test/**/*.test.js');

...

function getBundler() {
  // Our browserify bundle is made up of our unit tests, which
  // should individually load up pieces of our application.
  // We also include the browserify setup file.
  var testFiles = glob.sync('./test/**/*.test.js');

Why are no tests run? I have the test/setup/node.js file. What else could be missing? I suspect it is not due to the deprecation warning?

I tried using rollify as per your suggestion

gulp.task('build', ['clean'], function(done) {
  rollup.rollup({
    base: 'src',
    entry: config.entryFileName,
  }).then(function(bundle) {

Looks like the gulpfile fails which is why no tests are run. Are my test file patterns really invalid?
Then I add gulp-print

23:07 $ npm test

Looks like some dependency issue, but how do I get gulp test to write the stack trace on an error in a test file? Thanks ;)

Ah yes, coz the tests reference the uncompiled files. However, trying to run npm build and nothing happens. However if i run gulp build directly:

23:30 $ gulp build

    at /Users/kristianmandrup/repos/test123/senaca-projects/seneca-async/node_modules/esperanto/dist/esperanto.js:1858:10

So what is the story regarding these options? I have an index.js file in root, but I guess that doesn't go in dist on build? in my src, the entry file is seneca.js, hmm...

  "babelBoilerplateOptions": {
    "entryFileName": "index",
    "mainVarName": "seneca",
    "mochaGlobals": [
      "stub",
      "spy",
      "expect"
    ]
  }

Yup, that worked... maybe someone else will find these steps helpful?

Now do I reference the dist file or the src files from my tests? Neither seems to work for me (note I've been trying to port existing seneca project to babel with async)

Hi @kristianmandrup , can you make a separate issue? Thanks!

[kristianmandrup]

Sorry, was just tired and frustrated last night :P Will do!

[Harris-Miller]

A heads up: Rollup uses Acornjs for it's js AST. and as far as I can tell, Acornjs does not support ES7 decorators yet. Just trying to use Rollup on it's own throws an error for an unexpected character '@',

I take that back, Esperanto used Acronjs as well, however it was a much older version. Which is what most likely leads to the issue of the ES7 decorators syntax of:

@decorator
class MyClass {
  constructor() {}
}

throwing an error for unexpected character '@'

would be nice to have Acorn begin for on some ES7 syntax using the --ecma7 flag, probably should open up a ticket for that in Acorn's repo

Closing in favor of #230
