I think it's cool that someone has started on a python2dart translator. It will be interesting to see how some of the paradigm mismatches are resolved between Dart and Python, the biggest one being dynamism: Dart does not allow the program structure to change after it's been loaded, this means all imports have to be loaded before the program runs... conversely just about every major Python framework uses one form or another of dynamic imports, these will be impossible to port to Dart. This restriction is why Dart is so insanely fast.
The problem with any solution where you don't support 100% of Python is that you then don't benefit from the Python ecosystem in which case why bother use Python proper. This is the niche of projects like RapydScript, Coffeescript, etc. which are just syntax sugar over JS. I think any python2dart translator will find itself in the same boat: it won't be able to support 100% of Python and end up growing in complexity like Pyjs. In the end it might be easier to just port something like RapydScript or Coffeescript to output Dart code. I've been doing full time Python development for over 10 years now, I've gone to Python conferences and have loved the language and still do. Unfortunately the times have changed and I don't feel that Python has kept up. There are only two things going for Python right now: syntax and ecosystem. I think you really need to have both of those to make developing in Python worthwhile. Just having familiar syntax isn't worth it. Dart has a lot of really nice features that in my opinion make it way worth the inconvenience of semi-colons and squigglies. 1) It was designed from the ground up for Pyjs' use case: being translatable to JS. 2) Insanely fast start up (if using Dart VM). 3) Has all of the features you need for large apps: classes, interfaces, mixins, packages, etc. 4) Excellent async API, even more importantly it's consistent across the entire standard lib (client or server). If you've ever used Python Twisted than Dart will feel right at home. Everything from file access to websockets connections to button click events are based around Futures and Streams. Server side and client side (HTML5/DOM) all use the same async API. Another awesome thing about Dart is the optional typing, this results in wicked good IDE support. By having optional typing the IDE has a much better idea of what methods are available on an object and so auto-complete works superbly well compared to Python. - lex On Wed, Dec 10, 2014 at 6:34 AM, wb <warrenbuffettbilliona...@gmail.com> wrote: > One of advantages of Python2dart translator like Medusa is that we don't > have to spend time on making compatible in different platforms.
