Idempotent and minimal python library for rapid scripting.
Idempotent and minimal python 3 library for rapid scripting. Provide support for creating file, adding data to them, patching and so on.
(Ba)sh scripting is very easy to setup. So we end up using it all the time for simple procedural script.
Firing up python for a simple task seems too much but… what if a library will not only simplify scripting but offer some feature out of the box?
Sometimes is it useful to have idempotent script, like Ansible and Saltstack teach us.
runif enable an idempotent, functional programming-way.
- No dependency: it works with python library out of the box
- Python logging integration: debug, info level are tuned to provide you the right amount of information
- Battle tested on complex scenarios
I have the need for a idempotent script for a complex set of migration procedures. Bash was a pain. Java was an overkill so runif popped out.
Try the examples running them from the root directory
The run() function is very handy to fire direct command, like running git pull or so on (as in a bash script)
Note: runif it is NOT a replacement for Gradle, GNU Make, Maven, etc.
Install the package with > python setup.py install
Here an example of what happen if you run twice the same script:
$ python examples/stepByStep.py [INFO] runif.py.run_if_missed demo ===> step1 [INFO] runif.py.run_if_missed demo/demofile.txt ===> step2 [INFO] runif.py.run_if_missed demo/demofile2.c ===> step2 [INFO] runif.py.run_if_unmarked demo/demofile.txt ===> Step3 [INFO] runif.py.run_if_present demo/demofile.txt ===> <lambda> demo/demofile.txt present! [INFO] runif.py.run_each demo\demofile2.c ===> <lambda> ** demo\demofile2.c $ python examples/stepByStep.py [INFO] runif.py.run_if_present demo/demofile.txt ===> <lambda> demo/demofile.txt present! [INFO] runif.py.run_each demo\demofile2.c ===> <lambda> ** demo\demofile2.c
run_each is still unstable run_if_modified is brand new and not tested on a huge set of test cases. it is NOT thread safe
See ./CHANGELOG.md for the last modification
Install py.test with
pip install pytest
run with PYTHONPATH=. pytest
The PYTHONPATH variable is used to ensure you are using the current version and not another possibly installed one on your env
See https://docs.pytest.org/en/latest/example/index.html for usage examples
