## Overview
AutoGitSemVer uses commits in a git repository to calculate a semantic version. A commit's title and/or description can be used to increment a specific part of the semantic version and configuration files can be applied to control how the semantic version is generated. Finally, multiple, distinct semantic versions can be generated from different directories within the source tree.

#### Running with Python

```python
from io import StringIO
from pathlib import Path

from AutoGitSemVer import GetSemanticVersion
from dbrownell_Common.Streams.DoneManager import DoneManager


with DoneManager.Create(StringIO(), "") as dm:
    path = Path.cwd()

    result = GetSemanticVersion(dm, path)

print(result.semantic_version_string)
```

#### Updating the Version

A simplified [semantic version](https://semver.org) is defined by a `major` number, a `minor` number, and a `patch` number in the form:

    <major>.<minor>.<patch>

Changes to each of these numbers convey different meanings to those who have taken a dependency on the solution decorated by a semantic version:

- Changes to a `major` number indicate that backwards-**incompatible** functionality was introduced.
- Changes to a `minor` number indicate that backwards-**compatible** functionality was introduced.
- Changes to a `patch` number indicate that changes were introduced (but those changes did not introduce new functionality).

By default, AutoGitSemVer will increment the `patch` number for each git commit encountered.

##### Customizing the Update
The following tokens can be added anywhere in a git commit's title or description to increment the `major`, `minor`, or `patch` numbers:

| Semantic Version Number | Git Comment Token(s) | Example |
| --- | --- | --- |
| `major` | `+major` | 1.2.3 -> 2.0.0 |
| `minor` | `+minor`, `+feature` | 1.2.3 -> 1.3.0 |
| `patch` | `+patch` | 1.2.3 -> 1.2.4 |

##### Examples

###### Modifier in the Description

| | |
|-|-|
| Git Commit Title: | `Added feature Foo` |
| Git Commit Description: | `Foo lets a user... +minor` |

###### Modifier in the Title

| | |
|-|-|
| Git Commit Title: | `Added feature Foo (+minor)` |
| Git Commit Description: | `Foo lets a user...` |

#### Advanced Configuration

##### Configuration Files

The way in which semantic versions are generated can be customized through configuration files named:

- `AutoGitSemVer.json`
- `AutoGitSemVer.yaml`
- `AutoGitSemVer.yml`

These configuration files will impact the semantic versions generated for any changes in files or directories in the directory or its children. For example, given the directory structure:

```
<root>
|- File1.txt
|- DirectoryA
   |- AutoGitSemVer.json
   |- FileA.txt
   |- DirectoryA.1
      |- FileA1.txt
|- DirectoryB
   |- AutoGitSemVer.yaml
   |- FileB.txt
```

| File with Changes | Configuration Filename |
| --- | --- |
| `File1.txt` | None |
| `FileA.txt` | `DirectoryA/AutoGitSemVer.json` |
| `FileA1.txt` | `DirectoryA/AutoGitSemVer.json` |
| `FileB.txt` | `DirectoryB/AutoGitSemVer.yaml` |

The configuration file used when generating the semantic version is displayed when running AutoGitSemVer.

Information about the contents of these configuration files can be found in [AutoGitSemVerSchema.SimpleSchema](https://github.com/davidbrownell/AutoGitSemVer/blob/main/src/ConfigurationSchema/AutoGitSemVerSchema.SimpleSchema).

A simple example of a configuration file can be found [here](https://github.com/davidbrownell/AutoGitSemVer/blob/main/src/AutoGitSemVer.yaml).

## Installation

| Installation Method | Command |
| --- | --- |
| Via [uv](https://github.com/astral-sh/uv) | `uv add AutoGitSemVer` |
| Via [pip](https://pip.pypa.io/en/stable/) | `pip install AutoGitSemVer` |

### Verifying Signed Artifacts
Artifacts are signed and verified using [py-minisign](https://github.com/x13a/py-minisign) and the public key in the file `./minisign_key.pub`.

To verify that an artifact is valid, visit [the latest release](https://github.com/davidbrownell/AutoGitSemVer/releases/latest) and download the `.minisign` signature file that corresponds to the artifact, then run the following command, replacing `<filename>` with the name of the artifact to be verified:

```shell
uv run --with py-minisign python -c "import minisign; minisign.PublicKey.from_file('minisign_key.pub').verify_file('<filename>'); print('The file has been verified.')"
```
