A task runner that understands version control
Radish is a task runner that understands version control.
You define a command that applies to multiple subprojects in your repository and thenradish will figure out which projects have changed and run the command for just those projects. Radish isn’t a replacement for make, gulp, gradle, rake, or any other task runner. It’s a supplement for orchestrating other runners and scripts with some smarts from your version control repository.
If you’re using a CI/CD server like Concourse or GoCD which supports pipelines as first-class citizens you probably have no need for radish on your CI/CD server. It might still be useful on your dev machine, though.
Radish is available on PyPi as radish-run and can be installed on most systems with pip:
$ pip install radish-run
An example invocation of radish:
$ radish command tests --from 19abc023 --to 2514ecb1 Changed paths: - extensions/cool-extension/ - frontend/js/ Running tests for extensions/cool-extension/: ........... OK Running tests for frontend/js/: .......................... OK All commands ended successfully and ran in 9.75s.
radish configuration is a yaml file named Radishfile, because I can.
paths: - extensions/*/ # Mark each subdirectory in extensions as a path - frontend/js/ commands: # Runs from the directory denoted by paths above tests: default: bin/rspec spec frontend/js/: npm test
Take that you’re building a single page web app, it consists of two parts: - The backend that delivers JSON - The frontend that holds all the clicky bits that end-users see
Because cross-functional teams this project is in one repository, which is a great win for productivity. But it has a downside: when there are only changes to the backend, then all the tests for the frontend is still run. Finally, after running all tests it can get deployed, but then both sites get deployed despite nothing changing on the frontend.
So this is a crazy situation. It shouldn’t be. So this is where radish comes in. You tell radish about test and deploy, and what that means for both the backend and the frontend, then on your CI server you run the commands with the last green commit. Radish then figures out what has changed from the current commit and the last one, and only runs the command for those projects.
To get started make with your current global version of Python do:
$ git clone https://github.com/gaqzi/radish.git $ cd radish/ $ make develop $ make test
This will install all dependencies, check out the test repo, and then run all the tests.
