Embedding Version Information in Packages #

For a real example see [tinyssh-keyconvert@0.3.1...0.3.2](https://github.com/ansemjo/tinyssh-keyconvert/compare/0.3.1...0.3.2).

Version information should be single-sourced if you ask me. I’ve described my thoughts in a blog post, which culminated in my ansemjo/version.sh script.

To solve this problem for Python packages:

• Use version.sh script
  • Modify the release seperator to -dev
  • Use only version output, not describe, to conform to PEP440
• Read version from script with a subprocess command during packaging
• Write that version into a simple file that exports __version__ in your package
• In your script try to import said __version__ in a try-except-clause and fallback
• Now you can use the same version in the script .. yay!
