lib-cicd-github 1.0.0

CI/CD (Continuous Integration / Continuous Delivery) - utils for github actions

lib_cicd_github

Version v1.0.0 as of 2022-03-25 see Changelog

small utils for github actions:

• print colored banners

• wrap commands into run/success/error banners, with automatic retry

• resolve the branch to test, based on the environment variables

---

automated tests, Travis Matrix, Documentation, Badges, etc. are managed with PizzaCutter (cookiecutter on steroids)

Python version required: 3.6.0 or newer

tested on recent linux with python 3.6, 3.7, 3.8, 3.9, 3.10.0, pypy-3.8 - architectures: amd64

100% code coverage, flake8 style checking ,mypy static type checking ,tested under Linux, macOS, Windows, automatic daily builds and monitoring

You might try it right away in Jupyter Notebook by using the “launch binder” badge, or click here

Usage

• run a command passed as string

# to be used in the github action YAML File
# run a command passed as string, wrap it in colored banners, retry 3 times, sleep 30 seconds when retry
$> lib_cicd_github_cli run "description" "command -some -options" --retry=3 --sleep=30

• get the branch to work on from environment variables

$> BRANCH=$(lib_cicd_github_cli get_branch)

python methods:

• install, installs all needed dependencies to build and deploy the project

• Before You start, its highly recommended to update pip and setup tools:

python -m pip --upgrade pip
python -m pip --upgrade setuptools

• to install the latest release from PyPi via pip (recommended):

python -m pip install --upgrade lib_cicd_github

• to install the latest version from github via pip:

python -m pip install --upgrade git+https://github.com/bitranox/lib_cicd_github.git

# Insert following line in Your requirements.txt:
