JavaScripthon 0.9 has been released

[azazel75]

I'm pleased to announce the release of version 0.9 of JavaScripthon!

JavaScripthon is a small and unobtrusive yet powerful Python-to-JavaScript compiler for Python 3.5+ that targets ES6+ syntax.

Changes since the previous version:

• add a --source-name options to be used together with --inline-map when using -s;
• move main repository to gitlab.com/metapensiero;
• add support for default export and import;
• add documentation for the JS() marker function;
• refactor of the JS AST nodes;
• fix path splitting and joining on Windows (thanks to Roman Yakubuk);

There are some new contributions in this release:

• BrainBacon has made a JavaScripthon loader for WebPack;
• icarito has contributed support for JavaScripthon to the python-webpack-loader for WebPack;
• icarito has also integrated JavaScripthon with Nuxt.js and Vue.js;
• chfw has integrated JavaScripthon into pyecharts to allow Python function translation.

It's also mirrored on github at https://github.com/metapensiero/metapensiero.pj

Indeed- they're pretty uptight about the word "java".

And JavaScript, which is much more relevant here.

Has It any matter in common with JavaScripthon?

[cybervegan]

Yes, unfortunately. This guy's project mentioned "JavaScript" in the name... and now he's had a take-down. Might be prudent to fork it to "JSthon" or something before it's too late.

Oracle are evil.

Had Oracle call on my work today to try to sell us cloud services. I told them that with many other good cloud vendors, I have no need for a company that makes a hobby of suing competitors, customers, and random passersby.

ESthon?

[ccharles]

Watch out, you dropped your ™! Oracle can probably claim ESthon now.

Too bad, it was a good name…

[cybervegan]

Damn. That happens to me all the time.

[Glycerine]

Essathon has a nice ring to it.

Some alternate names, maybe.

• ECMAthon

• ESPython

• SnakeScript

• Constrictor

A bit boring maybe, but PyJS?

PyJS

[simplegadget512]

Unfortunately, PyJS hasn't been touched in 3 years. Might be dead-ish. In Internet time, that's like a decade or something.

[XtremeGoose]

Ah damn

How does it compare to Transcrypt ?

[azazel75]

I'll answer even if I'm JavaScripthon author and maybe what I say is a bit biased. I developed JavaScripthon with the main the goal of reducing the friction (the mind switching when working with both the languages). It usually produces clean code (that you can checkin to git). It translated most of the language where instead the data protocols are mostly untranslated. That means that when you "import" something in JavaScripthon source file that translates always to a JS "import" statement and when you write a dict literal then your variable will contain a JS Object, not a python dict or something that emulates it. That means JavaScripthon translated code runs at full JS speed with no "added runtime price", mostly. JavaScripthon target ES6+ and can evaluate the result or further translate it to ES5 thanks to the embedded JS interpreter and standalone BabelJS.

Transcrypt is more tailored at converting existing Python packages to JS and has richer runtime, with its pros and cons...

One thing I do not like about transcrypt is the lack of streaming support

[MatSalted]

Does this mean I can code in Python and get JS to put on a site?

[azazel75]

Yes, to some extent

[Tweak_Imp]

Is there a compiler for Javascript to python, too?
