Tsantsa

Tsantsa provides setuptools commands for minifying CSS and JS resources and compilation of SCSS resources to CSS using cssmin, slimit and pyScss.

scss, cssmin and slimit are pure Python packages and do not require any external commands.

This package is inspired by and based on the minify package by Sylvain Prat which uses the YUI compressor from Yahoo! Inc.

When you install tsantsa, three new commands are available:

tsantsa_js which minifies Javascript files
tsantsa_css which minifies CSS files
compile_scss which compiles SCSS files to CSS

See the Usage section for more information about these commands.

Installation

The Tsantsa commands are meant to be used in an existing python project. So, in order to make the commands available in your project, just add tsantsa to the requirements of your project, for example:

setup(
    ...
    install_requires=['tsantsa'],
    ...
)

Then, when you install your package, the Tsantsa commands will be available.

Usage

Tsantsa provides commands for minifying CSS and JS resources and compiling SCSS resources:

tsantsa_js which minifies Javascript files
tsantsa_css which minifies CSS files
compile_scss which compiles SCSS files to CSS

Minifying Javascript files

To show the options of the tsantsa_js command, just type:

$ python setup.py tsantsa_js --help

You should obtain something like this:

Common commands: (see '--help-commands' for more)

  setup.py build      will build the package underneath 'build/'
  setup.py install    will install the package

Global options:
  --verbose (-v)  run verbosely (default)
  --quiet (-q)    run quietly (turns verbosity off)
  --dry-run (-n)  don't actually do anything
  --help (-h)     show detailed help message
  --no-user-cfg   ignore pydistutils.cfg in your home directory

Options for 'tsantsa_js' command:
  --sources                sources files
  --output                 minified output filename. If you provide a template
                           output filename (e.g. "static/%s-min.ext"), the
                           source files will be minified individually
  --mangle                 mangle names

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

The tsantsa_js tool can be used on the command-line. Here is an example:

$ python setup.py tsantsa_js --sources static/*.js --output static/combined.js

But, the most useful way to use tsantsa_js is via a setup.cfg file located in your project root directory (that is, next to the setup.py file):

[tsantsa_js]
sources = static/one.js static/two.js
output = static/combined.js
mangle = yes

Then, we you run the tsantsa_js command, the command options will be read from the setup.cfg file in addition to the command-line arguments.

Note that, since there's a single output file for many sources, the sources files are merged into a single file which is compressed to produce a single minified file.

However, you may want to compress the sources files individually and obtain distinct minified files. In that case, you should provide a template output filename instead of a regular output filename. A template output filename is a filename with a %s in it, which will be substituted by the current source name being processed. For example:

[tsantsa_js]
sources = static/one.js static/two.js
output = static/%s-min.js

Running python setup.py tsantsa_js will then produce two minified files: static/one-min.js and static/two-min.js.

Minifying CSS files

You can also see the options of the tsantsa_css command, by typing:

$ python setup.py tsantsa_css --help

And here is the result:

Common commands: (see '--help-commands' for more)

  setup.py build      will build the package underneath 'build/'
  setup.py install    will install the package

Global options:
  --verbose (-v)  run verbosely (default)
  --quiet (-q)    run quietly (turns verbosity off)
  --dry-run (-n)  don't actually do anything
  --help (-h)     show detailed help message
  --no-user-cfg   ignore pydistutils.cfg in your home directory

Options for 'tsantsa_css' command:
  --sources     sources files
  --output      minified output filename. If you provide a template output
                filename (e.g. "static/%s-min.ext"), the source files will be
                minified individually

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

This command can be used about the same way as the tsantsa_js command, but it has less options.

Combining minification operations

You can also combine minification operations thanks to the builtin alias command (still specified in the setup.cfg file, but not available with pure distutils):

[alias]
minify_each_css = tsantsa_css --sources static/*.css --output static/%s-min.css
minify_each_js = tsantsa_js --sources static/*.js --output static/%s-min.js
minify_each = minify_each_css minify_each_js

Then call minify_each by typing:

$ python setup.py minify_each

Compiling SCSS files

You can also see the options of the compile_scss command, by typing:

$ python setup.py compile_scss --help

And here is the result:

Common commands: (see '--help-commands' for more)

  setup.py build      will build the package underneath 'build/'
  setup.py install    will install the package

Global options:
  --verbose (-v)  run verbosely (default)
  --quiet (-q)    run quietly (turns verbosity off)
  --dry-run (-n)  don't actually do anything
  --help (-h)     show detailed help message
  --no-user-cfg   ignore pydistutils.cfg in your home directory

Options for 'compile_scss' command:
  --sources    sources files
  --output     compiled css output file
  --loadpaths  paths pyScss will look ".scss" files in This can be the path to
               the compass framework or blueprint or compass-recepies, etc

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help
