Code to parse Arm Specification Language (ASL) files
Utility scripts to parse ASL files and the actual ASL language.
Preferably this is installed in a virtual environment. To create a virtual environment in the current directory write
python3 -m venv env/. To enter the virtual environment use
To install simply use pip:
pip3 install aslutils.
Installing for development
To install the package for development, clone it and then install it in editable mode:
pip3 install -e /path/to/aslutils/ (i.e. the directory that contains setup.py).
The documentation can be found at https://alehed.github.io/aslutils/
Generating the documentation
aslutils uses sphinx (
pip install sphinx) to generate the documentation. From the root folder the command to generate the html documentation is
sphinx-build -b html docs/source docs/build. The docs can then be found at
If anything in the source changes (class names, new classes etc.) the aslutils.rst and modules.rst files have to be regenerated. This can be done via
sphinx-apidoc -f -o docs/source/ aslutils. Do not edit those files manually as the changes will be overwritten once sphinx-apidoc is rerun.
Build time dependencies
In order to build the project locally, you need to have
antlr4 (https://www.antlr.org/) and the corresponding antlr4 python runtime installed (
pip install antlr4-python3-runtime==4.?.?, the version has to match the installed antlr version).
Building the parser
The ASL visitor code is generated with
antlr4 -Dlanguage=Python3 -no-listener -visitor ./aslutils/ASL.g4. This has to be done every time the file ASL.g4 is changed.
Note: I am currently the sole packager of this project, so this section is only for reference to my later self.
Once antlr is installed, this step is easy. The dependencies for packaging are: wheel, setuptools and twine (
pip install wheel setuptools twine)
After old versions are removed from the dist directory
rm dist/*, the package needs to be generated with:
python setup.py sdist bdist_wheel --universal. Then it can be uploaded using twine:
twine upload dist/*.
Again, this is only for myself.
- Decide to do a new release
- Fully regenerate the documentation and commit the changes
- Bump the version in setup.py
- Tag the latest commit and push it
- Publish the documentation with the provided script
- Do the step described in packaging
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
