# Bump the version of the vespa-cli formula and create a pull request to Homebrew repository.
#
# Homebrew's automated BrewTestBot must do the merge for the bottles to be published. When
# the PR has been merged check that the merge was done by their bot, and that installing
# the new version works by running: `brew update && brew install vespa-cli`.
#
# Example:
#
# $ make dist-homebrew
--dist-homebrew: dist-version
	brew update
	brew bump-formula-pr --version $(VERSION) --no-audit --no-browse vespa-cli

dist-homebrew:
	go run cond_make.go --dist-homebrew

# Create a GitHub release draft for all platforms. Note that this only creates a
# draft, which is not publicly visible until it's explicitly published.
#
# Once the release has been created this prints an URL to the release draft.
#
# This requires the GitHub CLI to be installed: brew install gh
#
# Example:
#
# $ make dist-github
--dist-github: dist
	gh release create v$(VERSION) --repo vespa-engine/vespa --notes-file $(CURDIR)/README.md --title "Vespa CLI $(VERSION)" \
