A platform for developing workbenches for Open Source Ecology (OSE).
OSE defines a "workbench" as a set of tools in CAD software to design and make a particular machine.
Each workbench OSE develops for one of it's machines has certain common development-time or "dev-time" needs and dependencies.
For example, running unit tests, making documentation, and generating code to streamline workbench development.
Rather than duplicate the approaches to each of these needs, ose-workbench-platform abstracts those needs into a common platform so they aren't the concern of individual OSE workbench maintainers.
Each workbench maintainer doesn't need to know or care about the particular versions and libraries we use to solve those needs, nor the particular configuration.
Having a common platform for OSE workbench development also makes it easier for developers to readily switch between workbenches by providing a common tool-set.
ose-workbench-platform provides a command-line interface (CLI), via the osewb command, containing commands for common dev-time tasks such as running all tests, making documentation, initializing new workbenches, and even generating code for common tasks.
Install the ose-workbench-platform package from the gbroques and conda-forge channel in a dedicated conda environment named osewb (short for Open Source Ecology WorkBench) and don't ask for confirmation:
conda create --name osewb --channel gbroques --channel conda-forge --yes ose-workbench-platform
Activate your new osewb environment:
conda activate osewb
Test your installation:
osewb --help
You can deactivate this environment later by running:
conda deactivate
We use Conda to create a reproducible virtualized OSE workbench development environment with requisite dependencies for development-time tasks like running FreeCAD, executing unit tests, and generating documentation from source-code comments.
In order to perform various development-time tasks for a workbench, you must first:
- Create a conda environment from the
environment.ymlfile located in the root of the workbench repository - Activate the environment with
conda activate <environment name>
Note, each workbench will have it's own separate environment.
Workbench environments will be named after the base package in the workbench repository (e.g. ose3dprinter, osetractor, osepowercube, etc.).
Some common commands relating to managing environments with conda are documented in the below table.
| Description | Command |
|---|---|
| Creating the environment | conda env create --file environment.yml |
| Activating the environment | conda activate <environment name> |
| Deactivating the environment | conda deactivate |
Refer to the Conda CLI reference documentation for additional information.
For running unit tests we use pytest.
For test coverage, we use coverage.py and pytest-cov.
For building documentation, we use Sphinx.
For hosting documentation, we use a free service for open-source projects called Read the Docs.
For a modern and mobile-friendly look, we use Read the Docs Sphinx Theme.
The osewb command contains various sub-commands for performing common dev-time tasks of a OSE workbench.
$ osewb -h ↵
usage: osewb <command> [<args>]
A collection commands for OSE workbench development.
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
Commands:
{test,lint,docs,make,browse,br}
test Run tests in workbench
lint Lint code
docs Make documentation
make Commands for making new code
browse (br) Commands for opening documents in a web browser
Each sub-command may have flags and arguments, and additional information can be discovered via osewb <command> -h or --help.
Is osewb too many characters to type? We recommend aliasing the osewb command as ose to reduce typing and increase speed even further.
For further convenience, any command over four characters shall include a short-alias under four characters or less. For example, br is the short-alias for the five-character browse command.
OSE Workbench Platform includes a test command for interacting with the test-suite of a workbench.
$ osewb test -h ↵
usage: osewb test
optional arguments:
-h, --help show this help message and exit
-c, --coverage Run tests with coverage, and generate report
To run the entire unit-test suite for a workbench, run:
osewb test
For running tests with coverage and generating a coverage report, pass the -c or --coverage flag to the test command:
osewb test --coverage
OSE Workbench Platform includes a lint command for linting the code of a workbench.
osewb lint
The lint command will:
- Run
flake8with configuration located in .flake8. - Run
mypyfor static type checking with configuration located in .mypy.ini.
For automatically fixing some linter issues, pass the -f or --fix flag to the lint command:
osewb lint --fix
This will run isort and autopep8 recursively on the root of the workbench repository.
For additional information, see:
OSE Workbench Platform includes a docs command for building the documentation of a workbench.
$ osewb docs -h ↵
usage: osewb docs [command]
optional arguments:
-h, --help show this help message and exit
Commands:
{screenshot,ss}
screenshot (ss)
Take screenshots of parts for documentation.
The docs command will:
- Remove auto-generated files such as the
_build/and any auto-generated Sphinx sources. - Re-generate
docs/_build/,docs/<base package>/,docs/freecad/<base package>/by runningsphinx-build . _buildwithindocs/using the Sphinx configuration specified indocs/conf.py
For additional information, see sphinx-build and Sphinx Configuration.
Additionally, you may pass a screenshot or ss sub-command to the docs command for taking screenshots of parts in a workbench:
osewb docs ss
This will look for parts in the <base package>/part package of the current workbench, and save thumbnail screen shots in the docs/_static/screenshot/ directory for each part.
OSE Workbench Platform includes a build command for building a workbench.
osewb build
The build command aggregates the following commands into one:
- Run tests with coverage -
osewb test --coverage - Lint all code -
osewb lint - Ensure the documentation builds -
osewb docs
The build command exits with 0 or 1 to pass or fail the build depending upon whether the above commands return non-zero exit codes.
OSE Workbench Platform includes a make command for "making" new code.
$ ose make -h ↵
usage: osewb make <command>
optional arguments:
-h, --help show this help message and exit
Commands:
{workbench,wb,part,model,part-feature,pf,command}
workbench (wb) Make Workbench
part Make Part class
model Make Model class
part-feature (pf) Make Part Feature creation function
command Make Command class
Navigate to where you want to create your new workbench. Then run:
osewb make workbench <machine_display_name>
Where <machine_display_name> is the name of the machine in Title Case. If this contains spaces, then surround the value in double-quotes "".
$ osewb make workbench Tractor ↵
Workbench initialized in "ose-tractor-workbench" directory.
Perform the following commands to get started:
1. Change directories and initialize the git repository:
cd ose-tractor-workbench && git init
2. Create a conda environment and activate it:
conda env create --file environment.yml && conda activate osetractor
3. Verify your installation:
osewb -h
The above examples initializes a new workbench, in a ose-tractor-workbench directory, with the basic structure and files needed.
$ tree ose-tractor-workbench --dirsfirst ↵
