zc.buildout recipe for closurebuilder

Project description

This is a simple wrapper around the closurebuilder tools from the Closure project from Google.

Dependencies

Setup some JavaScript files.

>>> import os.path
>>> os.mkdir(os.path.join(sample_buildout, 'js'))
>>> write('js/a.js', '''
... goog.provide('pwt.provideA');
...
... goog.require('pwt.provideB');
... ''')
>>> write('js/b.js', '''
... goog.provide('pwt.provideB');
... ''')
>>> mkdir('js/goog')
>>> write('js/goog/base.js', open(os.path.join(os.path.dirname(__file__), "goog/base.js")).read())

roots

Generate a dependency file specifing where all your JavaScript files are located within your project.

>>> write('buildout.cfg', '''
... [buildout]
... parts = deps.js
...
... [deps.js]
... recipe = pwt.recipe.closurebuilder:dependency
... output = %(dir)s/deps.js
... roots = %(dir)s/js
... ''' %{'dir': sample_buildout})
>>> print system(buildout)
Installing deps.js.
<BLANKLINE>
>>> cat('deps.js')
// This file was autogenerated by buildout[deps.js].
// Please do not edit.
goog.addDependency('a.js', ['pwt.provideA'], ['pwt.provideB']);
goog.addDependency('b.js', ['pwt.provideB'], []);
goog.addDependency('goog/base.js', [], []);

roots with prefix

Generate a dependency file specifing where all your JavaScript files are located within your project. Sometimes files are served under different namespaces, then we use the root_with_prefix option.

>>> write('buildout.cfg', '''
... [buildout]
... parts = deps.js
...
... [deps.js]
... recipe = pwt.recipe.closurebuilder:dependency
... output = %(dir)s/deps.js
... root_with_prefix = %(dir)s/js /media
... ''' %{'dir': sample_buildout})
>>> print system(buildout)
Uninstalling deps.js.
Installing deps.js.
<BLANKLINE>
>>> cat('deps.js')
// This file was autogenerated by buildout[deps.js].
// Please do not edit.
goog.addDependency('/media/a.js', ['pwt.provideA'], ['pwt.provideB']);
goog.addDependency('/media/b.js', ['pwt.provideB'], []);
goog.addDependency('/media/goog/base.js', [], []);

Compile

Using the information above, generate a small minimized version of your JavaScript application.

>>> write('buildout.cfg', '''
... [buildout]
... parts = deps.js compiled.js
...
... [deps.js]
... recipe = pwt.recipe.closurebuilder:dependency
... output = %(dir)s/d1.js
... roots = %(dir)s/js
...
... [compiled.js]
... recipe = pwt.recipe.closurebuilder:compile
... dependency = deps.js
... output = %(dir)s
... inputs = %(dir)s/js/a.js
... ''' %{'dir': sample_buildout})
>>> print system(buildout) #doctest:+ELLIPSIS
Uninstalling deps.js.
Installing deps.js.
Installing compiled.js.
root: Compiling with the following command: java -jar ...
<BLANKLINE>
>>> ls(sample_buildout)
-  .installed.cfg
d  bin
-  buildout.cfg
-  d1.js
-  db5293d69c7cf152489f73b7221b146d.js
