Browser-Linker
==============

    >>> from pyjs import browser
    >>> from pyjs.testing import (
    ...     outputContainsSystemFiles,
    ...     outputContainsPlatforms,
    ...     outputContainsFiles,
    ...     )

Let us generate some python code.

    >>> import tempfile, os, shutil
    >>> tmp = tempfile.mkdtemp()

    >>> lib_path = os.path.join(tmp, 'lib')
    >>> pp = os.path.join(lib_path, 'mypackage')
    >>> os.makedirs(pp)
    >>> mp = os.path.join(pp, '__init__.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... # package
    ... """)
    >>> f.close()
    >>> mp = os.path.join(pp, 'index.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... def main():
    ...     print 1
    ... """)
    >>> f.close()

    >>> output = os.path.join(tmp, 'output')
    >>> l = browser.BrowserLinker('mypackage.index',
    ...                          output=output,
    ...                          platforms=['ie6', 'mozilla'],
    ...                          path=[lib_path])

    >>> l()

By default the javascript code is compiled to a subdirectory in the
output directory.

    >>> sorted(os.listdir(os.path.join(output, 'lib')))
    ['mypackage.index.js', 'mypackage.js', 'pyjslib.__mozilla__.js', 'pyjslib.js']

    >>> out_file = os.path.join(output, 'mypackage.index.ie6.cache.html')
    >>> print file(out_file).read()
    <html>...
    pyjslib = ...
    mypackage = $pyjs.loaded_modules["mypackage"] = function (__mod_name__)...

    >>> outputContainsSystemFiles(output)
    >>> outputContainsPlatforms(output, 'mypackage.index', ['ie6', 'mozilla'])
    >>> outputContainsFiles(output, ['mypackage.index.html'])

Let us add another package with some public folder.

    >>> pp = os.path.join(lib_path, 'second_package')
    >>> os.makedirs(pp)
    >>> mp = os.path.join(pp, '__init__.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... # package
    ... """)
    >>> f.close()
    >>> mp = os.path.join(pp, 'widget.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... # do something
    ... """)
    >>> f.close()
    >>> p_dir = os.path.join(pp, 'public')
    >>> os.mkdir(p_dir)
    >>> mp = os.path.join(p_dir, 'second.css')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... /* some css */
    ... """)
    >>> f.close()

    >>> l()

Public folders are merged together, but only if something of the
package gets imported, which is not the case in this example right
now.

    >>> outputContainsSystemFiles(output)
    >>> outputContainsPlatforms(output, 'mypackage.index', ['ie6', 'mozilla'])
    >>> outputContainsFiles(output, ['mypackage.index.html'])

So let us add an import.

    >>> mp = os.path.join(lib_path, 'mypackage', 'index.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... import second_package.widget
    ... def main():
    ...     print 1
    ... if __name__=='__main__':
    ...     main()
    ... """)
    >>> f.close()

Now we have the contents of the public folder in our output directory.

    >>> l()
    >>> print sorted(os.listdir(output))
    [..., 'second.css'...]

Now we will add a sub module and import it.

    >>> mp = os.path.join(lib_path, 'mypackage', 'util.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... def log(msg):
    ...     print msg
    ... """)
    >>> f.close()

    >>> mp = os.path.join(lib_path, 'mypackage', 'index.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... import second_package.widget
    ... import util
    ... def main():
    ...     print 1
    ... if __name__=='__main__':
    ...     main()
    ... """)
    >>> f.close()

    >>> l()
    >>> outputContainsSystemFiles(output)
    >>> outputContainsPlatforms(output, 'mypackage.index', ['ie6', 'mozilla'])
    >>> outputContainsFiles(output, ['mypackage.index.html'])

    >>> op = os.path.join(output, 'mypackage.index.ie6.cache.html')
    >>> f = file(op, 'r')
    >>> content = f.read()
    >>> f.close()

    >>> 'mypackage.util.log' in content
    True

Use an import of an unknown module does not raise an exception because
this is raised at runtime.

    >>> pp = os.path.join(lib_path, 'mypackage')
    >>> mp = os.path.join(pp, 'index.py')
    >>> f = file(mp, 'w')
    >>> f.write("""
    ... import unknown.module
    ... """)
    >>> f.close()
    >>> l = browser.BrowserLinker('mypackage.index',
    ...                          output=output,
    ...                          platforms=['ie6', 'mozilla'],
    ...                          path=[lib_path])
    >>> l()


Multifile Linking
=================

In order to be able to debug scripts in e.g. Firebug it is usefull to
have smaller script files, the multifile option does this by writing
script tags into the generated cache.html file.

    >>> l = browser.BrowserLinker('mypackage.index',
    ...                           output=output,
    ...                           multi_file=True,
    ...                           platforms=['ie6', 'mozilla'],
    ...                           path=[lib_path])
    >>> l()

    >>> op = os.path.join(output, 'mypackage.index.ie6.cache.html')
    >>> f = file(op)
    >>> content = f.read()
    >>> f.close()

    >>> print content
    <html>
    ...
    --></script>
    <BLANKLINE>
    <script type="text/javascript" src="_pyjs.js"></script>
    <script type="text/javascript" src="sprintf.js"></script>

    <BLANKLINE>

Cachebusting
============

The cache buster option appends the md5 hash of the contents of files
to their paths.

    >>> l = browser.BrowserLinker('mypackage.index',
    ...                           output=output,
    ...                           multi_file=True,
    ...                           cache_buster=True,
    ...                           platforms=['ie6', 'mozilla'],
    ...                           path=[lib_path])
    >>> l()

    >>> op = os.path.join(output, 'mypackage.index.nocache.html')
    >>> f = file(op)

The script selectors point to the according files.

    >>> print f.read()
    <html>...
    O(["true","ie6"],"mypackage.index.ie6.2da78b3ac76b1a1c9879e3e8a9997eb0.cache.html");
    O(["true","mozilla"],"mypackage.index.mozilla.1b658fcd34b8f530360aa5de3cd9e8c3.cache.html");...

    >>> from pprint import pprint
    >>> pprint(sorted(os.listdir(output)))
    ['...
     'mypackage.index.ie6.2da78b3ac76b1a1c9879e3e8a9997eb0.cache.html',...
     'mypackage.index.mozilla.1b658fcd34b8f530360aa5de3cd9e8c3.cache.html',
     ...']

Also the libfiles which are generated from multifile option are upated.

    >>> op = os.path.join(
    ...     output, 'mypackage.index.ie6.2da78b3ac76b1a1c9879e3e8a9997eb0.cache.html')
    >>> f = file(op)
