Requirements

Python 2.6

For javascript minimization you can use:

• jsmin or slimit (you must install the egg first)
• Any program which reads the code from stdin and writes to stdout like yui compressor or UglifyJS

Install

You can install jspack like a simple python egg:

• Using easy_install: easy_install jstools
• Using pip: pip install jstools
• If you use buildout, add it to the eggs list in your buildout.cfg, or as a dependency of one of your own packages in setup.py.

The code is available in the jspack repo

Usage

If you have a config file (test.cfg) like:

[DEFAULT]
minimizer = jsmin

[concatenated.js]
# yui compressor
minimizer = inout: java -jar compressor.jar --type js
# Can be used to replace the js tags
html = test.html
files = file/relative/to/root.js
        /absolute/file.js

[compressed.js]
minimizer = slimit
files = file/relative/to/root.js
        js/two.js

[css/all.css]
root = css
minimizer = none
files = one.css
        two.css

And generates concatenated.js, compressed.js and css/all.css

If root option is not specified, the relative files are considered relative to the config parent directory (test.cfg).

You can use the help:

$ bin/jspack  --help
Usage:
jspack [options] file_or_directory

Typical Usage:

1. First create cfg files:
   $ jspack -w htmlfile_or_directory
2. Now we can edit the jspack.cfg files and customize
3. Then generate minimized:
   $ jspack cfgfile_or_directory
4. Last, replace script tags:
   $ jspack -rn cfgfile_or_directory

Note: 3 and 4 can be summarized which: $ jspack -r cfgfile_or_directory


Options:
  -h, --help            show this help message and exit
  -w, --write-config    For each FILE.html file write a FILE.jspack.cfg file
                        which later can be used to produce FILE-minimized.js
  -o, --ovewrite-config
                        Overwrite a jspack.cfg file if exists. Use which -w
                        option
  -i INCLUDE, --include-only=INCLUDE
                        When parsing html (to generate a .jspack.cfg file) ,
                        include only javascript files which match this regular
                        expression. Default (?!http), Use  for no restriction
  -s, --allow-strict-mode
                        When concatenate js files, dont't drop 'use strict'
                        lines. Default is remove strip mode
  -n, --no-pack         no packing when using the jspack.cfg. Only usefull
                        with -r option for only replace
  -r, --replace-script-tags
                        Replace the script tags in html files
  -q, --quiet           Supress non error output
  -v, --verbose         Vebose output (debug mode)
