# Tasks

## publish

Run: once
Requires: environment

Input: mode
Environment: mode=patch

Bumps project new version, build and publish the package to repository.

```bash

xc bump-version "$mode"

.venv/bin/poetry build
.venv/bin/poetry publish

```

## bump-version

Run: once
Requires: environment

Inputs: mode
Environment: mode=patch

Prepare and commit a version update in a Git repository. Checks for uncommitted changes, ensures the current branch is master, verifies if there are any changes since the last tag, and bumps the version number.

After validating the readiness for an update, it prompts to proceed. Once confirmed, the script updates the pyproject.toml and .pre-commit-config.yaml files if necessary, commits the changes, tags the new version, and pushes the updates to the remote repository.

```bash
#!/bin/zsh

uncommited="$(git diff --cached --name-only | sort -u | tr '\n' ' ' | xargs)"
if [ -n "$uncommited" ]; then
    echo "uncommited changes found"
    exit 1
fi

#

branch="$(git rev-parse --quiet --abbrev-ref HEAD 2>/dev/null)"
if [ -z "$branch" ]; then
    exit 1
elif [ "$branch" == "master" ]; then
    echo "using main master mode"
else
    exit 1

    echo "future tag $revision not found, continue"

elif [ -z "$retval" ] && [ -n "$revision" ]; then

    echo "future tag $version already set to commit $revision, sync with remote branch!"
    exit 1

else
    echo "something went wrong, version: '$version' revision: '$revision', retval: '$retval'"
    exit 2
fi

# non destructive stop here

git push origin $branch
git-restore-mtime --skip-missing || echo "datetime restoration failed, return: $?, skip"

Once confirmed, the script updates the pyproject.toml and .pre-commit-config.yaml files if necessary, commits the changes, tags the new version, and pushes the updates to the remote repository.\n\n```bash\n#!/bin/zsh\n\nuncommited=\"$(git diff --cached --name-only | sort -u | tr '\\n' ' ' | xargs)\"\nif [ -n \"$uncommited\" ]; then\n    echo \"uncommited changes found\"\n    exit 1\nfi\n\n#\n\nbranch=\"$(git rev-parse --quiet --abbrev-ref HEAD 2>/dev/null)\"\nif [ -z \"$branch\" ]; then\n    exit 1\nelif [ \"$branch\" == \"master\" ]; then\n    echo \"using main master mode\"\nelse\n    exit 1\nfi\n\n#\n\nchanges=\"$(git ls-files --deleted --modified --exclude-standard)\"\nchanges=\"$(printf \"$changes\" | sort -u | tr '\\n' ' ' | xargs)\"\n\nif [ \"$changes\" == \"README.md\" ]; then\n    echo \"pipeline development mode\"\nelif [ -n \"$changes\" ]; then\n    echo \"uncommited changes found\"\n    exit 1\nfi\n\ngit fetch --tags --force\ncurrent=\"$(git describe --tags --abbrev=0)\"\n[ -z \"$current\" ] && exit 1\n\namount=\"$(git rev-list --count $current..HEAD)\"\nuncommited=\"$(git diff --cached --name-only | sort -u | tr '\\n' ' ' | xargs)\"\n\nif [ \"$amount\" -eq 0 ] && [ -z \"$uncommited\" ]; then\n    echo \"no changes since $current\"\n    exit 1\nfi\n\nversion=\"$(bump \"$mode\" \"$current\")\"\n[ -z \"$version\" ] && exit 1\n\nrevision=\"$(git rev-parse \"$version\" 2>/dev/null)\" || retval=\"$?\"\n\nif [ \"$retval\" -eq 128 ]; then\n    echo \"future tag $revision not found, continue\"\n\nelif [ -z \"$retval\" ] && [ -n \"$revision\" ]; then\n\n    echo \"future tag $version already set to commit $revision, sync with remote branch!\"\n    exit 1\n\nelse\n    echo \"something went wrong, version: '$version' revision: '$revision', retval: '$retval'\"\n    exit 2\nfi\n\n# non destructive stop here\n\ngit push origin $branch\ngit-restore-mtime --skip-missing || echo \"datetime restoration failed, return: $?, skip\"\nls -la\necho \"we ready for bump $current -> ${version}, press ENTER twice to proceed or ESC+ENTER to exit\"\n\ncounter=0\nwhile : ; do\n    read -r key\n\n    if [[ $key == $'\\e' ]]; then\n        exit 1\n\n    elif [ -z \"$key\" ]; then\n        counter=$((counter + 1))\n        if [ \"$counter\" -eq 2 ]; then\n            break\n        fi\n    fi\ndone\n\n# actions starts here\n\nxc update-pyproject \"$current\" \"$version\"\n\nuncommited=\"$(git diff --cached --name-only | sort -u | tr '\\n' ' ' | xargs)\"\nchanges=\"$(git ls-files --deleted --modified --exclude-standard)\"\nchanges=\"$(printf \"$changes\" | sort -u | tr '\\n' ' ' | xargs)\"\n\nif [[ \"$uncommited\" =~ \"\\bpyproject\\.toml\\b\" ]] || [[ \"$changes\" =~ \"\\bpyproject\\.toml\\b\" ]]; then\n    xc add-pyproject\nfi\n\nif [[ \"$uncommited\" =~ \"\\bci/\\.pre-commit-config\\.yaml\\b\" ]] || [[ \"$changes\" =~ \"\\bci/\\.pre-commit-config\\.yaml\\b\" ]]; then\n    xc add-precommit\nfi\n\nuncommited=\"$(git diff --cached --name-only | sort -u | tr '\\n' ' ' | xargs)\"\nif [ -n \"$uncommited\" ]; then\n    git commit -m \"$branch: $version\"\nfi\n\ngit tag -a \"$version\" -m \"$version\"\ngit push --tags\n\necho \"version update to ${version}\"\n```\n\n## environment\n\nRun: once\n\nMake virtualenv for project build & test tools, install pre-push hook.\n\n```bash\n\nif [ ! -d \".venv\" ]; then\n    virtualenv --python python3.11 \".venv\"\n    .venv/bin/pip install --upgrade pip\n    .venv/bin/pip install --upgrade poetry pre-commit tomli tomli_w docformatter rstcheck\n\nelse\n    [ -f \".venv/bin/activate\" ]\n\nfi\n\n.venv/bin/pre-commit install --config ci/.pre-commit-config.yaml --install-hooks --overwrite --color always --hook-type pre-push\n```\n\n## autoupdate\n\nRun: once\n\nAutoupdate pre-commit hooks if the last update was more than 7 days ago.\n\n```bash\n\nctime=\"$(date +%s)\"\nmtime=\"$(git log -1 --format=%ct ci/.pre-commit-config.yaml)\"\n\nresult=$(((7*86400) - (ctime - mtime)))\n\nif [ \"$result\" -le 0 ]; then\n    update\nfi\n\n```\n\n## update\n\nRun: once\nRequires: environment\n\nUpdate all pre-commit hook versions to latest releases.\n\n```bash\n\n.venv/bin/pre-commit autoupdate --config ci/.pre-commit-config.yaml --color always\n\n```\n\n## check\n\nRequires: environment, autoupdate\n\nRuns all defined pre-commit hooks.\n\n```bash\n.venv/bin/pre-commit run --config ci/.pre-commit-config.yaml --color always --all\n```\n\n## clean\n\nRun: once\n\nClean up the project working directory: remove build/, .venv/, and .ruff_cache/ directories, as well as all .pyc files and __pycache__ directories.\n\n```bash\n\nrm -rf build/ || true\nrm -rf .venv/ || true\nrm -rf .ruff_cache/ || true\n\nfind . -name \"*.pyc\" -delete || true\nfind . -name \"__pycache__\" -type d -exec rm -rf {} + || true\n\n```\n\n## update-pyproject\n\nRun: once\nRequires: environment, autoupdate\n\nUpdate version in pyproject.toml file based on provided old and new version tags.
