ci_exec

A wrapper package designed for running continuous integration (CI) build steps using Python 3.6+.

Managing cross platform build scripts for CI can become tedious at times when you need to e.g., maintain two nearly identical scripts install_deps.sh and install_deps.bat due to incompatible syntaxes. ci_exec enables a single file to manage this using Python.

The ci_exec package provides a set of wrappers / utility functions designed specifically for running build steps on CI providers. It is

Logging by Default

Commands executed, including their full command-line arguments, are logged. This includes any output on stdout / stderr from the commands. The logging resembles what set -x would give you in a shell script. For commands that will take a long time, as long as output is being produced, this will additionally prevent timeouts on the build.

Failing by Default

Any command that does not succeed will fail the entire build. An attempt to exit with the same exit code as the command that failed will be performed. Meaning the CI provider will correctly report a failed build.

Convenient

ci_exec affords users the ability to write shell-like scripts that will work on any platform that Python can run on. A simple example:

from ci_exec import cd, which

cmake = which("cmake")
ninja = which("ninja")
with cd("build", create=True):
    cmake("..", "-G", "Ninja", "-DCMAKE_BUILD_TYPE=Release")
    ninja("-j", "2", "test")

Installation

ci_exec is available on PyPI. It can be installed using your python package manager of choice:

$ pip install ci-exec

Note

The PyPI package has a -: ci-exec, not ci_exec.

There is also a setup.py here, so you can also install it from source:

$ pip install git+https://github.com/svenevs/ci_exec.git@master
