About this Episode
In the last episode, we talked about going from script to supported package.
I worked on a project called subark and did the packaging with flit.
Today's episode is a continuation where we add new features to a supported package and how to develop and test a flit based package.
- viewing stages of a project with git tags
- flit support for editable installs
- flit description entry in pyproject.toml to put README on pypi.
- development dependencies in pyproject.toml
- editor layout for optimal TDD-ing
- test case grouping
- modifications to traditional TDD that helps me develop faster.
code and command snippets from episode:
For git checkout of versions:
$ git clone https://github.com/okken/submark.git $ cd submark $ python3 -m venv venv --prompt submark $ source ./bin/activate (submark) $ git checkout v0.1 ... etc ... (submark) $ git checkout v0.7
To grab the latest again:
(submark) $ git checkout master
pyproject.toml change for README to show up on pypi:
[tool.flit.metadata] ... description-file = "README.md" ...
Adding dev dependencies to pyproject.toml:
[tool.flit.metadata.requires-extra] test = ["pytest", "pytest-cov", "tox"]
Installing in editable mode (in top level repo directory). works in mac, linux, windows:
