jsmin 2.1.6

JavaScript minifier.

JavaScript minifier.

Usage

from jsmin import jsmin
with open('myfile.js') as js_file:
    minified = jsmin(js_file.read())

You can run it as a commandline tool also:

python -m jsmin myfile.js

As yet, jsmin makes no attempt to be compatible with ECMAScript 6 / ES.next / Harmony. If you’re using it on Harmony code, though, you might find the quote_chars parameter useful:

from jsmin import jsmin
with open('myfile.js') as js_file:
    minified = jsmin(js_file.read(), quote_chars="'\"`")

Where to get it

• install the package from pypi

• get the latest release from latest-release on github

• get the development version from master on github

Contributing

Issues and Pull requests will be gratefully received on Github. The project used to be hosted on bitbucket and old issues can still be found there.

If possible, please make separate pull requests for tests and for code: tests will be added to the latest-release branch while code will go to master.

Unless you request otherwise, your Github identity will be added to the contributor’s list below; if you prefer a different name feel free to add it in your pull request instead. (If you prefer not to be mentioned you’ll have to let the maintainer know somehow.)

Build/test status

Both branches are tested with Travis: https://travis-ci.org/tikitu/jsmin

The latest-release branch (the version on PyPI plus any new tests) is tested against CPython 2.6, 2.7, 3.2, and 3.3. Currently:

If that branch is failing that means there’s a new test that fails on the latest released version on pypi, with no fix yet released.

The master branch (development version, might be ahead of latest released version) is tested against CPython 2.6, 2.7, 3.2, and 3.3. Currently:

If master is failing don’t use it, but as long as latest-release is passing the pypi release should be ok.
