Mustache project templates using Python and Groome
You can use Molt to decrease the amount of boilerplate code you need to write when starting new projects: the README, copyright notices, license info, logging configuration, option parsing, test harness, packaging information, .gitignore, directory hierarchy, etc.
A minimal sample usage looks like–
$ molt -c path_to_config.json path_to_template_dir/
Feedback is welcome. You can also file bug reports and feature requests on the GitHub issues page.
Molt supports the following Python versions:
- Python 2.7
- Python 3.2
Python 3.x support is coming soon. Since Molt is a development tool, there are no plans to support Python 2.6 or earlier.
Molt’s dependencies are–
The installation process below installs these dependencies automatically.
$ pip install molt
$ molt --run-tests
Start with the demo Groome template to play with:
$ molt --create-demo --output demo $ ls -p demo expected/ lambdas/ partials/ sample.json structure/
Render the template with the sample context provided:
$ molt --output output --config demo/sample.json demo
Run the newly-created project (which can also be seen here)):
$ python output/hello.py world Hello, world!
For help documentation and available options–
$ molt -h
Note the --visualize and --with-visualize options that let you quickly visualize entire directory contents.
$ molt --visualize output
If using Python, you can also use Molt as a library (though the API is not yet stable). See the Molter class in the molt.molter module.
If using GitHub, after forking–
$ git clone email@example.com:yourusername/molt.git $ cd molt $ git remote add upstream git://github.com/cjerdonek/molt.git $ git fetch upstream
To run unit tests–
$ python test_molt.py
To test Molt with multiple versions of Python (with a single command!), you can use tox:
pip install tox tox
If you don’t have all Python versions listed in tox.ini, you can do–
tox -e py27 # for example
To run from source any molt command of the form–
$ molt [options] [DIRECTORY]
$ python -m molt.commands.molt [options] [DIRECTORY]
To include the Groome tests in your test runs, initialize and update the Groome project submodule–
$ git submodule init $ git submodule update
To run a subset of the tests, you can filter your test runs using one or more prefixes. For example–
$ python test_molt.py molt.test.common molt.test.dir
Python 3 Tips
Molt is written in Python 2, so the code must be converted to Python 3 prior to using with Python 3. The installation process does this automatically.
To convert the code to Python 3 manually, run the following using Python 3 (with Distribute installed)–
python setup.py build
This writes the converted code to a subdirectory of the project directory called build.
It is possible (though not recommended) to convert the code without using setup.py. You can try this with 2to3, as follows (two steps):
2to3 --write --nobackups --no-diffs --doctests_only molt 2to3 --write --nobackups --no-diffs molt
This converts the code (and doctests) in place.
To import molt from a source distribution while using Python 3, be sure that you are importing from a directory containing the converted code (e.g. from the build directory after converting), and not from the original (unconverted) source directory. Otherwise, you will get a syntax error. You can help prevent this by not running the Python IDE from the project directory when importing Molt while using Python 3.
