Brython-3.2.7 released
Pierre Quentel
Hi,
I have just released Brython version 3.2.7 and updated brython.info.
The main change in this release is performance improvement : thanks to various optimisations, the pystone test
runs 2.5 times faster than with the previous version. It is still 15
times slower than CPython, but it was hundreds of
times a few months ago, and I have a few ideas to make things better in the near future.
Another change is the implementation of list comprehensions and generator expressions, now using self-executing anonymous functions.
The complete changelog is below. Thanks to all contributors !
- Pierre
New features
============
- implement browser.select(selector) : alias for document.get(selector=...)
- implement element.closest(tagName) : return the first element with specified
tag name above element
- add and document html.SVG (dynamically create an SVG panel)
- add file package.json, so that Brython is referenced as an npm package
Implementation
==============
- change implementation of list comprehensions and generator expressions : now
translated into self-executing anonymous functions
- speed improvements :
. in argument parsing
. by reducing the calls to $B.get_class(obj)
. by cleaning the attributes .modules, .bound and .type of __BRYTHON__ after
a script is parsed
. by caching the result of method to_js()
- improvement of interaction with Javascript constructors (by caryoscelus)
- remove options passed to function brython() : CORS
- mention BrowserStack in the README file (they offer us an account)
- if a JS function returns undefined, the Brython wrapper returns None instead
of raising an exception
- add a --no-docs option to server.py to improve the developer experience (by
Kiko Correoso)
- change sys.argv to use option "args" passed to brython()
Bug fixes
=========
- raise TypeError when the object passed as a base class is not a class.
- fix bugs and change callback implementation in _ajax.js
- bug : setting function attribute __doc__
- a few names were leaking in the global Javascript namespace
- for a classmethod, the first argument is the class factory, not the class
dictionary
- bug with argument "args" of exception classes and instances
- bugs on dict implementation, detected by tests/unittests with test_dict.py
- fix some bad behaviour with webbrowser.py module (by Kiko Correoso)
- fix issue with absolute vlue of complex numbers (idem)
