Create & Maintain Salt Formulae

A Copier template that initializes a project structure for developing Salt formulae.

It's an opinionated variant of the official template-formula and began its life as a Cookiecutter/Cruft template.

Migration from previous template

salt-template-formula

Template version 0.0.1 is identical to the last Cruft template. Expect this template to diverge significantly from the template-formula in future releases.

You can use the following command inside the project root to migrate to this template (requires jq):

jq '.context.cookiecutter |
    with_entries(select(.key | test("^[^_]"))) |
    with_entries(.key |=
        if . == "name" then "service_name"
        elif . == "abbr" then "service_abbr"
        elif . == "git_username" then "author"
        else . end) |
    with_entries(if .key == "needs_repo" then .value = .value == "y" else . end)
' .cruft.json > tmp_copier_answers && \
copier copy --trust --vcs-ref=0.0.1 https://github.com/lkubb/salt-formula-copier --data-file=tmp_copier_answers --skip \* . && \
git add --intent-to-add .copier-answers.yml && \
git clean -ffd && \
rm -f .cruft.json && \
git commit --no-verify -am "Migrate to Copier template"; rm -f tmp_copier_answers

You should then immediately update (at least to version 0.0.8, which excludes .copier-answers.yml from pre-commit YAML linting, but leaves everything else as before, and fixes two template bugs). Choose general as the template flavor when updating.

copier update --trust --skip-answered  # --vcs-ref=0.0.7

salt-template-formula-compose

For projects generated from the compose template-formula, you can follow similar steps as documented for salt-template-formula. Use the following command:

jq '.context.cookiecutter |
    with_entries(select(.key | test("^[^_]"))) |
    with_entries(.key |=
        if . == "name" then "service_name"
        elif . == "abbr" then "service_abbr"
        elif . == "git_username" then "author"
        else . end)
' .cruft.json > tmp_copier_answers && \
copier copy --trust --vcs-ref=0.0.3 https://github.com/lkubb/salt-formula-copier --data flavor=compose --data-file=tmp_copier_answers --skip \* . && \
git add --intent-to-add .copier-answers.yml && \
git clean -ffd && \
rm -f .cruft.json && \
echo "flavor_recorded: compose" >> .copier-answers.yml && \
git commit --no-verify -am "Migrate to Copier template"; rm -f tmp_copier_answers

Because of a bug in versions <0.0.7, updating from here needs a workaround. Ensure the repo state is completely clean with no untracked files/uncommitted changes before running:

copier update --trust --skip-answered --vcs-ref=0.0.7 && \
git add .copier-answers.yml  .pre-commit-config && \
git commit -m "Update to template version 0.0.7" && \
git reset --hard HEAD && git clean -ffd

salt-tool-template-formula

For projects generated from the tool template-formula, you can follow similar steps as documented for salt-template-formula. Use the following command:

jq '.context.cookiecutter |
    with_entries(select(.key | test("^[^_]"))) |
    with_entries(.key |=
        if . == "name" then "service_name"
        elif . == "abbr" then "service_abbr"
        elif . == "git_username" then "author"
        elif . == "modstate" then "extmods"
        elif . == "usersettings" then "user_settings"
        else . end) |
    with_entries(. |=
        if .key == "needs_repo" then .value = .value == "y"
        elif .key == "extmods" then .value = if .value == "y" then ["execution", "state"] else [] end
        elif .key == "has_service" then .value = .value == "y"
        elif .key == "mac_library" then .value = .value == "y"
        elif .key == "mac_cask" then .value = .value == "y"
        elif .key == "has_xdg" then .value = .value == "y"
        elif .key == "needs_xdg_help" then .value = .value == "y"
        elif .key == "has_conffile_only" then .value = .value == "y"
        elif .key == "has_configsync" then .value = .value == "y"
        elif .key == "has_config_template" then .value = .value == "y"
        elif .key == "has_completions" then .value = .value == "y"
        elif .key == "has_tests" then .value = .value == "y"
        else . end)
' .cruft.json > tmp_copier_answers && \
copier copy --trust --vcs-ref=0.0.5 https://github.com/lkubb/salt-formula-copier --data flavor=app --data-file=tmp_copier_answers --skip \* . && \
git add --intent-to-add .copier-answers.yml && \

Acknowledgement

This project is heavily based on the excellent work done in saltstackformulas/template-formula.
