Hmm - what happens if you change directory to the root of the QxCompiler repo
and run ./test/compile-app-demo.js?

Dunno why it looks for presets in my home dir. In my previous experiment,
everything went smooth (except that it didn't in fact collect any qooxdoo deps,
since I removed all plugins - but transpiling itself went fine).
As for uglify - ah, that was stupid. I used original uglify, not uglify-js.
Just tried the latter (2.6.1) - indeed, it takes ~10 secs for qxt. Not bad.

Got it – it was a bug in my plugin I introduced a while ago, but Chrome
obviously supports arrow functions natively so I didn’t pick up that the
translation wasn’t happening any more. The .babelrc is not needed for this
because we’re using it embedded, I think the .babelrc is only for the CLI
That’s very a good point about the polypill BTW because it’s not being included
and it should be, I’ll add that in tomorrow.
The problem with translations is fixed now too, sorry about that I should have
deleted the output directory before retesting :oops:
What options are you running Uglify with, and what version are you running?
I’m using "uglify boot.js -m -c”, I just timed it on mine and it’s mangled the
qxt app in 11 seconds (I’m using uglify 2.6.1) Still not great but better than
30 secs :) I’ve nearly got Uglify done, but stopped for dinner and then saw
your email so switched back.
I’ve done the #! entries too
I’ve pushed a new release, give it a go :)

Just a quick follow-up on Babel - I've rolled back to yesterday's version,
edited lib/qxcompiler/ClassFile.js:218, replaced that plugins array with
presets: [ "es2015" ]. Suddenly, it worked :)
I'm still wondering why it doesn't try to look for any .babelrc file. It's
clearly stated in the docs that the "babelrc" option is true by default. And it
definitely would be good to have control over Babel via (optional) config file.
Another issue to consider is that not every ES6 feature is implemented via code
transformation. Some (ex., Promises) require babel-polyfill. (Mention in the
docs? Integrate polyfill into build?)

Hi John,
That pace you're keeping, it's incredible :) Glad to hear translations finally
landed!
Unfortunately, I couldn't make them work :(

(removed qxcompiler dir & did clean checkout, didn't help either)
Re: Babel - sadly, didn't make it work either :( that arrow function in
qxt/Application.js goes unchanged first to [source|build]-output/transpiled,
then to [source|build]-output/script. The same with string templates, etc. Note
the above [BABEL] message - that means, Babel is invoked, but doesn't apply any
actual transformations. I tried "strace -e trace=open node
compile-app-demo.js", and didn't see it open .babelrc or any plugin and/or
preset modules. Could you please make sure it's indeed enabled? If it works for
you, could you please assist me in tracing/debugging (since I'm a newbie in a
Node world)?
As for script compression, I played a bit with the standalone uglify tool.
Works pretty fine, but it takes ~30 seconds to process a skeleton app. Do you
think it can be sped up if integrated into QxCompiler?
Minor issue: test/*.js scripts could have a shebang string (#!/usr/bin/node)
and +x mode so that they could be run directly, without typing "node ..." each
time.
Cheers!
Dimitri
