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.

How to use AutoGitSemVer

Running the Executable

From a terminal window, run:

Scenario	Command Line	Output

Running with 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 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.

A simple example of a configuration file can be found here.

Installation

Installation Method	Command
Via uv	uv add AutoGitSemVer
Via pip	pip install AutoGitSemVer

Verifying Signed Artifacts

Artifacts are signed and verified using py-minisign and the public key in the file ./minisign_key.pub.

To verify that an artifact is valid, visit the latest release 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:

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.')"
