Parse Julia version

Python

Use pathlib to read and tomllib to parse julia_version from Manifest.toml. (requires Python >= 3.11)

import tomllib; from pathlib import Path; print(tomllib.loads(Path("Manifest.toml").read_text())["julia_version"])

And it’s easy to run in a bash shell,

python -c 'import tomllib; from pathlib import Path; print(tomllib.loads(Path("Manifest.toml").read_text())["julia_version"])'

In GitHub actions,

echo "resolved=$(python -c 'import tomllib; from pathlib import Path; print(tomllib.loads(Path("Manifest.toml").read_text())["julia_version"])')" >> "$GITHUB_OUTPUT"

Bash

Use awk to parse julia_version from Manifest.toml.

echo "resolved=$(awk -F '"' '/^[[:space:]]*julia_version/ {print $2}' Manifest.toml)" >> "$GITHUB_OUTPUT"
