## Convert changelog to dict

Convert changelog markdown file following [keep a changelog](https://keepachangelog.com/en/1.1.0/) format into python dict.

```python
import keepachangelog

changes = keepachangelog.to_dict("path/to/CHANGELOG.md")
```

`changes` would look like:

```python
changes = {
    "1.1.0": {
        "changed": [
            "Enhancement 1 (1.1.0)",
            "sub enhancement 1",
            "sub enhancement 2",
            "Enhancement 2 (1.1.0)",
        ],
        "metadata": {
            "release_date": "2018-05-31",
            "version": "1.1.0",
            "semantic_version": {
                "major": 1,
                "minor": 1,
                "patch": 0,
                "prerelease": None,
                "buildmetadata": None,
            },
            "url": "https://github.test_url/test_project/compare/v1.0.1...v1.1.0",
        },
    },
    "1.0.1": {
        "fixed": [
            "Bug fix 1 (1.0.1)",
            "sub bug 1",
            "sub bug 2",
            "Bug fix 2 (1.0.1)",
        ],
        "metadata": {
            "release_date": "2018-05-31",
            "version": "1.0.1",
            "semantic_version": {
                "major": 1,
                "minor": 0,
                "patch": 1,
                "prerelease": None,
                "buildmetadata": None,
            },
            "url": "https://github.test_url/test_project/compare/v1.0.0...v1.0.1",
        },
    },
    "1.0.0": {
        "deprecated": ["Known issue 1 (1.0.0)", "Known issue 2 (1.0.0)"],
        "metadata": {
            "release_date": "2017-04-10",
            "version": "1.0.0",
            "semantic_version": {
                "major": 1,
                "minor": 0,
                "patch": 0,
                "prerelease": None,
                "buildmetadata": None,
            },
            "url": "https://github.test_url/test_project/releases/tag/v1.0.0",
        },
    },
}
```

For a markdown file with the following content:

```markdown
# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

[1.0.1]: https://github.test_url/test_project/compare/v1.0.0...v1.0.1
[1.0.0]: https://github.test_url/test_project/releases/tag/v1.0.0
```

`show_unreleased` parameter can be specified in order to include `Unreleased` section information.
Note that `release_date` metadata will be set to None in such as case.

### Retrieving the raw content

If for some reason you would like to retrieve the raw content of a release you can use `to_raw_dict` instead.

```python
import keepachangelog

changes = keepachangelog.to_raw_dict("path/to/CHANGELOG.md")
```

`changes` would look like:

```python
changes = {
    "1.1.0": {
        "raw": """### Changed
- Enhancement 1 (1.1.0)
 - sub enhancement 1
 - sub enhancement 2
- Enhancement 2 (1.1.0)""",
        "metadata": {
            "release_date": "2018-05-31",
            "version": "1.1.0",
            "semantic_version": {
                "major": 1,
                "minor": 1,
                "patch": 0,
                "prerelease": None,
                "buildmetadata": None,
            },
            "url": "https://github.test_url/test_project/compare/v1.0.1...v1.1.0",
        },
    },
    "1.0.1": {
        "raw": """### Fixed
- Bug fix 1 (1.0.1)
 - sub bug 1
 - sub bug 2
- Bug fix 2 (1.0.1)""",
        "metadata": {
            "release_date": "2018-05-31",
            "version": "1.0.1",
            "semantic_version": {
                "major": 1,
                "minor": 0,
                "patch": 1,
                "prerelease": None,
                "buildmetadata": None,
            },
            "url": "https://github.test_url/test_project/compare/v1.0.0...v1.0.1",
        },
    },
    "1.0.0": {
        "raw": """### Deprecated
- Known issue 1 (1.0.0)
- Known issue 2 (1.0.0)""",
        "metadata": {
            "release_date": "2017-04-10",
            "version": "1.0.0",
            "semantic_version": {
                "major": 1,
                "minor": 0,
                "patch": 0,
                "prerelease": None,
                "buildmetadata": None,
            },
            "url": "https://github.test_url/test_project/releases/tag/v1.0.0",
        },
    },
}
```

## Convert dict to changelog

Convert a python dict (resulting from [`keepachangelog.to_dict`](#convert-changelog-to-dict)) to a changelog markdown content following [keep a changelog](https://keepachangelog.com/en/1.1.0/) format.

```python
import keepachangelog

changes = keepachangelog.to_dict("path/to/CHANGELOG.md")
content = keepachangelog.from_dict(changes)
```

## Release

You can create a new release by using `keepachangelog.release` function.

```python
import keepachangelog

new_version = keepachangelog.release("path/to/CHANGELOG.md")
```

This will:
* If `new_version` parameter is not provided, guess the new version number and return it:
  * `Removed` or `Changed` sections will be considered as breaking changes, thus incrementing the major version.
  * If the only section is `Fixed`, only patch will be incremented.
  * Otherwise, minor will be incremented.
* Update changelog.
  * Unreleased section content will be moved into a new section.
  * `[Unreleased]` link will be updated.
  * New link will be created corresponding to the new section (based on the format of the Unreleased link).

## Endpoint

### Starlette

An helper function is available to create a [starlette](https://www.starlette.io) endpoint to retrieve changelog as JSON.

```python
from starlette.applications import Starlette
from keepachangelog.starlette import add_changelog_endpoint


app = Starlette()
# /changelog endpoint will return the dict extracted from the changelog as JSON.
add_changelog_endpoint(app, "path/to/CHANGELOG.md")
```

Note: [starlette](https://pypi.python.org/pypi/starlette) module must be installed.

### Flask-RestX

An helper function is available to create a [Flask-RestX](https://flask-restx.readthedocs.io/en/latest/) endpoint to retrieve changelog as JSON.

```python
import flask
import flask_restx
from keepachangelog.flask_restx import add_changelog_endpoint


app = flask.Flask(__name__)
api = flask_restx.Api(app)
# /changelog endpoint will return the dict extracted from the changelog as JSON.
add_changelog_endpoint(api, "path/to/CHANGELOG.md")
```

Note: [flask-restx](https://pypi.python.org/pypi/flask-restx) module must be installed.

## How to install
1. [python 3.6+](https://www.python.org/downloads/) must be installed
2. Use pip to install module:
```sh
python -m pip install keepachangelog
```
