zope.tal Package Readme
=======================
Overview
--------
The Zope3 Template Attribute Language (TAL) specifies the custom namespace
and attributes which are used by the Zope Page Templates renderer to inject
dynamic markup into a page. It also includes the Macro Expansion for TAL
(METAL) macro language used in page assembly.
The dynamic values themselves are specified using a companion language,
TALES (see the 'zope.tales' package for more).
See: http://www.zope.org/Wikis/DevSite/Projects/ZPT/TAL%20Specification%201.4
Getting PyPy
------------
Check out the latest version of PyPy:
http://codespeak.net/pypy/dist/pypy/doc/getting-started.html#svn-check-out-run-the-latest-pypy-as-a-two-liner
Also make sure ctypes is available for your Python.
Running the tests
-----------------
To run the tests:
$ python2.4 bootstrap.py
$ bin/buildout
$ export PYTHONPATH=/path/to/pypy-dist:$PYTHONPATH
$ bin/test
Compiling with PyPy's RPython
-----------------------------
To compile the rpython:
First, you need to set up PYTHONPATH so it has the required packages on the
path:
$ export PYTHONPATH=/path/to/buildout/src:/path/to/buildout/eggs/zope.interface:/path/to/buildout/eggs/zope.i18nmessageid:$PYTHONPATH
Now, run the following command to compile::
$ python /path/to/pypy-dist/pypy/bin/compilemodule.py _talinterpreter -p zope.tal
The first argument is name of the RPython sub-package you want to
compile, the option `-p` specifies the name of the package where this RPython
sub-package is found.
The compiled module will be placed in
/tmp/usession-XX/_talinterpreter/_talinterpreter.so.
To run the tests with the compiled module, you need to move the `.so` file to
src/zope/tal and to rename `_talinterpreter`.
Alternatilvely, you could run the following command::
$ python /path/to/pypy-dist/pypy/bin/compilemodule.py _talinterpreter -p zope.tal -d /path/to/src/zope/tal
where `-d` option specifies the directory where to copy the compiled module.
You'd still need to rename the existing `_talinterpreter` sub-package.
