Makefile - How should I extract the version number embedded in `pyproject.toml`?

I have a python project with a pyproject.toml file. Typically I store the project's version number in pyproject.toml like this:

% grep version pyproject.toml 
version = "0.0.2"
%

I want to get that version number into a Makefile variable regardless of how many spaces wind up around the version terms.

What should I do to extract the pyproject.toml version string into a Makefile environment variable called VERSION?

Solution

  • An alternative solution to parse major.minor.patch, based on @Mike Pennington's answer:

    grep -m 1 version pyproject.toml | grep -e '\d.\d.\d' -o
