## Requirements
* [github client](https://github.com/cli/cli#installation)
* [gitchub_changelog_generator](https://github.com/github-changelog-generator)
* [github access token](https://github.com/github-changelog-generator/github-changelog-generator#github-token)

## Export changelog token

```bash
export CHANGELOG_GITHUB_TOKEN=token
```

## Set release information

0.3.5 should always be the previous release as it's the last pyhs100 release in HISTORY.md which is the changelog prior to github release notes.

```bash
export NEW_RELEASE=x.x.x.devx
export PREVIOUS_RELEASE=0.3.5
```

## Create a branch for the release

```bash
git checkout master
git fetch upstream master
git rebase upstream/master
git checkout -b release/$NEW_RELEASE
```

## Update the version number

```bash
poetry version $NEW_RELEASE
```

## Update dependencies

```bash
poetry install --all-extras --sync
poetry update
```

## Run pre-commit and tests

```bash
pre-commit run --all-files
pytest kasa
```

## Create release summary (skip for dev releases)

Write a short and understandable summary for the release.  Can include images.

### Create $NEW_RELEASE milestone in github

If not already created

### Create new issue linked to the milestone

```bash
gh issue create --label "release-summary" --milestone $NEW_RELEASE --title "$NEW_RELEASE Release Summary" --body "## Release Summary"
```

You can exclude the --body option to get an interactive editor or go into the issue on github and edit there.

### Close the issue

Either via github or:

```bash
gh issue close ISSUE_NUMBER
```

## Generate changelog

### For pre-release

EXCLUDE_TAGS will exclude all dev tags except for the current release dev tags.

Regex should be something like this `^((?!0\.7\.0)(.*dev\d))+`. The first match group negative matches on the current release and the second matches on releases ending with dev.

```bash
EXCLUDE_TAGS=${NEW_RELEASE%.dev*}; EXCLUDE_TAGS=${EXCLUDE_TAGS//"."/"\."}; EXCLUDE_TAGS="^((?!"$EXCLUDE_TAGS")(.*dev\d))+"
echo "$EXCLUDE_TAGS"
github_changelog_generator --base HISTORY.md --user python-kasa --project python-kasa --since-tag $PREVIOUS_RELEASE --future-release $NEW_RELEASE -o CHANGELOG.md --no-issues --exclude-tags-regex "$EXCLUDE_TAGS"
```

### For production

```bash
github_changelog_generator --base HISTORY.md --user python-kasa --project python-kasa --since-tag $PREVIOUS_RELEASE --future-release $NEW_RELEASE -o CHANGELOG.md --no-issues --exclude-tags-regex 'dev\d$'
```

You can ignore warnings about missing PR commits like below as these relate to PRs to branches other than master:
```
Warning: PR 908 merge commit was not found in the release branch or tagged git history and no rebased SHA comment was found
```


## Export new release notes to variable

```bash
export RELEASE_NOTES=$(grep -Poz '(?<=\# Changelog\n\n)(.|\n)+?(?=\#\#)' CHANGELOG.md | tr '\0' '\n' )
echo "$RELEASE_NOTES"  # Check the output and copy paste if neccessary
```

## Commit and push the changed files

```bash
git commit --all --verbose -m "Prepare $NEW_RELEASE"
git push upstream release/$NEW_RELEASE -u
```

## Create a PR for the release, merge it, and re-fetch the master

### Create the PR
```
gh pr create --title "Prepare $NEW_RELEASE" --body "$RELEASE_NOTES" --label release-prep --base master
```

### Merge the PR once the CI passes

Create a squash commit and add the markdown from the PR description to the commit description.

```bash
gh pr merge --squash --body "$RELEASE_NOTES"
```

### Rebase local master

```bash
git checkout master
git fetch upstream master
git rebase upstream/master
```

## Create a release tag

Note, add changelog release notes as the tag commit message so `gh release create --notes-from-tag` can be used to create a release draft.

```bash
git tag --annotate $NEW_RELEASE -m "$RELEASE_NOTES"
git push upstream $NEW_RELEASE
```

## Create release

### Pre-releases

```bash
gh release create "$NEW_RELEASE" --verify-tag --notes-from-tag --title "$NEW_RELEASE" --draft --latest=false --prerelease

```

### Production release

```bash
gh release create "$NEW_RELEASE" --verify-tag --notes-from-tag --title "$NEW_RELEASE" --draft --latest=true
```

## Manually publish the release

Go to the linked URL, verify the contents, and click "release" button to trigger the release CI.
