Jinja2 extensions for Moban¶
Since version 0.2, mobanfile supports an extra field plugin_dir, along with template_dir. When you put your own jinja2 filters, tests and globals in your moban repo, you can let moban know about them via this keyword.
Importantly, you have to have __init__.py file in your plugin_dir. Otherwise, your plugins will NOT be loaded.
def __init__(self, template_dirs, extensions=None): pass @patch("lml.plugin.PluginManager.load_me_now", return_value=FakeEngine) def test_default_mako_type(_): # fake mako engine = ENGINES.get_engine("fake", , "") assert engine.engine_cls.__name__ == "FakeEngine" @raises(exceptions.NoThirdPartyEngine) def test_unknown_template_type(): ENGINES.get_engine("unknown_template_type", , "")
It is possible to write an installable package including your own jinja2 filters, tests and globals. Please email me for more details.
Template engine extension for Moban¶
moban version 0.2 started using lml to employ loose couple plugins. Other template engines, such as marko, haml can be plugged into moban seamless.
In order plugin other template engines, it is to write a lml plugin. The following is an example starting point for any template engine.
@PluginInfo( constants.TEMPLATE_ENGINE_EXTENSION, tags=["file", "extensions", "for", "your", "template"] ) class Engine(object): def __init__(self, template_dirs): """ A list template directories will be given to your engine class """ def get_template(self, template_file): """ Given a relative path to your template file, please return a templatable thing that does the templating function in next function below """ def apply_template(self, template, data, output): """ Given the template object from `get_template` function, and data as python dictionary, and output as intended output file, please return "utf-8" encoded string. """
After you will have finished the engine plugin, you can either place it in plugin_dir in order to get it loaded, or make an installable python package. In the latter case, please refer to yehua: doing that in less than 5 minutes.
