Introduction

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.

Pre-Requisites

1. Install Git
2. Install Miniconda

Virtual Development Environment

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.

Unit Tests

For running unit tests we use pytest.

For test coverage, we use coverage.py and pytest-cov.

Documentation

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.

Commands

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:
  {env,test,docs,init,browse}
    env                 Commands for interacting with environments
    test                Run tests in workbench
    docs                Make documentation
    init                Initialize new workbench
    browse              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.

env

OSE Workbench Platform includes a env command to make interacting with the requisite environment for running tests and building documentation easier.

$ osewb env -h ↵
usage: osewb env <command>

optional arguments:
  -h, --help   show this help message and exit

Commands:
  {bootstrap}
    bootstrap  Bootstrap environment

In order to run the test and docs commands, you must first:

1. Create a conda environment from the environment.yml file located in the root of the workbench repository
2. Activate the environment with conda activate <environment name>
3. Bootstrap the environment with the osewb env boostrap command

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.

test

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

docs

OSE Workbench Platform includes a docs command for building the documentation of a workbench.

osewb docs

The docs command will:

• Delete the docs/_build/ directory
• Delete the docs/<base package>/ directory
• Re-generate docs/_build/ and docs/<base package>/ by running sphinx-build . _build within docs/ using the Sphinx configuration specified in docs/conf.py
• Generate property tables for each Model class in the workbench and output them as .csv files in docs/property_table/

For additional information, see sphinx-build and Sphinx Configuration.

init

OSE Workbench Platform includes a init command for initializing a new workbench.

$ osewb init -h ↵
usage: osewb init <machine_display_name>

positional arguments:
  machine_display_name  Name of machine in title-case. Surround in double-
                        quotes if name contains spaces (e.g. "CEB Brick
                        Press")

optional arguments:
  -h, --help            show this help message and exit

Navigate to where you want to initialize a directory for your new workbench. Then run:

osewb init <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 init Tractor ↵
Workbench initialized in "ose-tractor-workbench" directory.

Next, change directories and initialize the git repository:

    cd ose-tractor-workbench && git init

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 ↵

browse

OSE Workbench Platform includes a browse covenience command for opening documentation and coverage reports in a web browser.

$ osewb browse -h ↵
usage: osewb browse <command>

optional arguments:
  -h, --help       show this help message and exit

Commands:
  {docs,coverage}
    docs           Opens docs in web browser
    coverage       Opens coverage report in web browser

The docs command opens docs/_build/index.html in a web browser, while coverage opens htmlcov/index.html in a web browser.

Generating Code

Within the root of a workbench repository, run the make command.

For example,

osewb make command AddMotor

Will generate a new AddMotor command class.
