Function parsePyprojectDeps

cmd/pulumi.go:1097–1110

parsePyprojectDeps extracts dependency specifiers from pyproject.toml without a full TOML parser. It handles two common layouts: 1. PEP 621 / uv: [project] dependencies = ["pkg>=1.0", ...] 2. Poetry: [tool.poetry.dependencies] pkg = ">=1.0" Python version constraints (key == "python") are

(pyprojectPath string)

// Python version constraints (key == "python") are skipped.
// Returns a slice of pip-compatible specifiers, e.g. ["pulumi==3.228.0", "pulumi-aws==7.23.0"].
func parsePyprojectDeps(pyprojectPath string) []string {
	data, err := os.ReadFile(pyprojectPath)
	if err != nil {
		return nil
	}
	content := string(data)

	// Try PEP 621 [project] dependencies array first.
	if deps := parsePEP621Deps(content); len(deps) > 0 {
		return deps
	}
	// Fall back to Poetry [tool.poetry.dependencies] table.
	return parsePoetryDeps(content)
}

// parsePEP621Deps extracts deps from a [project] dependencies = [...] array.
