A Python package to create XForms for ODK Collect.
Project description
pyxform is a Python library that makes writing forms for ODK Collect and Enketo easy by converting XLSForms (Excel spreadsheets) into ODK XForms. The XLSForms format is used in a number of tools.
XLS(X) documents used as input must follow to the XLSForm standard and the resulting output follows the ODK XForms standard.
formhub.org uses the repo here: https://github.com/modilabs/pyxform
pyxform is a major rewrite of xls2xform.
Running the latest release of pyxform
For those who want to convert forms at the command line, the latest official release of pyxform can be installed using pip:
pip install pyxform
The xls2xform command can then be used:
xls2xform path_to_XLSForm [output_path]
The currently supported Python versions for pyxform are 3.7 and 3.8.
Running pyxform from local source
Note that you must uninstall any globally installed pyxform instance in order to use local modules. Please install java 8 or newer version.
From the command line, complete the following. These steps use a virtualenv to make dependency management easier, and to keep the global site-packages directory clean:
# Get a copy of the repository. mkdir -P ~/repos/pyxform cd ~/repos/pyxform git clone https://github.com/XLSForm/pyxform.git repo # Create and activate a virtual environment for the install. /usr/local/bin/python3.8 -m venv venv . venv/bin/activate # Install the pyxform and it's production dependencies. (venv)$ cd repo (venv)$ pip install -e . (venv)$ python pyxform/xls2xform.py --help (venv)$ xls2xform --help # same effect as previous line (venv)$ which xls2xform # ~/repos/pyxform/venv/bin/xls2xform
To leave and return to the virtualenv:
(venv)$ deactivate # leave the venv, scripts not on $PATH $ xls2xform --help # -bash: xls2xform: command not found $ . ~/repos/pyxform/venv/bin/activate # reactivate the venv (venv)$ which xls2xform # scripts available on $PATH again ~/repos/pyxform/venv/bin/xls2xform
Installing pyxform from remote source
pip can install from the GitHub repository. Only do this if you want to install from the master branch, which is likely to have pre-release code. To install the latest release, see above.:
pip install git+https://github.com/XLSForm/pyxform.git@master#egg=pyxform
You can then run xls2xform from the commandline:
xls2xform path_to_XLSForm [output_path]
Development
To set up for development / contributing, first complete the above steps for “Running pyxform from local source”, then complete the below.:
pip install -r dev_requirements.pip
You can run tests with:
nosetests
On Windows, use:
nosetests -v -v --traverse-namespace ./tests
Before committing, make sure to format the code using black:
black pyxform tests
If you are using a copy of black outside your virtualenv, make sure it is the same version as listed in requirements_dev.pip.
In case the pre-commit.sh hooks don’t run, also run the code through isort (sorts imports) and flake8 (misc code quality suggestions). The syntax is the same as above for black.
Writing tests
Make sure to include tests for the changes you’re working on. When writing new tests you should add them in tests folder. Add to an existing test module, or create a new test module. Test modules are named after the corresponding source file, or if the tests concern many files then module name is the topic or feature under test.
When creating new test cases, where possible use PyxformTestCase as a base class instead of unittest.TestCase. The PyxformTestCase is a toolkit for writing XLSForms as MarkDown tables, compiling example XLSForms, and making assertions on the resulting XForm. This makes code review much easier by putting the XLSForm content inline with the test, instead of in a separate file. A unittest.TestCase may be used if the new tests do not involve compiling an XLSForm (but most will). Do not add new tests using the old style XFormTestCase.
Documentation
To check out the documentation for pyxform do the following:
pip install Sphinx==1.0.7 cd your-virtual-env-dir/src/pyxform/docs make html
Change Log
Releasing pyxform
Make sure the version of ODK Validate in the repo is up-to-date:
pyxform_validator_update odk update ODK-Validate-vx.x.x.jar
Run all tests through Validate by setting the default for run_odk_validate to kwargs.get("run_odk_validate", True) in pyxform/tests_v1/pyxform_test_case.py.
Draft a new GitHub release with the list of merged PRs. Follow the title and description pattern of the previous release.
Checkout a release branch from latest upstream master.
Update CHANGES.txt with the text of the draft release.
Update README.rst, setup.py, pyxform/__init__.py with the new release version number.
Commit, push the branch, and initiate a pull request. Wait for tests to pass, then merge the PR.
In a clean new release only directory, checkout master.
Create a new virtualenv in this directory to ensure a clean Python environment:
/usr/local/bin/python3.8 -m venv pyxform-release . pyxform-release/bin/activate
Install the production and packaging requirements:
pip install -e . pip install wheel twine
Cleanup build and dist folders:
rm -rf build dist pyxform.egg-info
Prepare sdist and bdist_wheel distributions:
python setup.py sdist bdist_wheel
Publish release to PyPI with twine:
twine upload dist/pyxform-*-py2.py3-none-any.whl dist/pyxform-*.tar.gz
Tag the GitHub release and publish it.
