Generate changelog from Git commits.

• Python 3.6, 3.7 and 3.8

Documentation is available on Read the Docs.

Latest stable version on PyPI:

pip install matyan

See Basic concepts section to get impression on possible commit methodology and assumptions taken.

Generate changelog:

generate-changelog

Generate changelog skipping orphaned commits:

In some cases you would only want to show what has been done with tickets and skip all non-ticket related commits.

generate-changelog --no-other

Generate changelog between two releases:

In other cases you would want to show what has been done since last release. The following example would generate changelog since version 0.0.1 to version 0.0.3.

generate-changelog 0.0.1..0.0.3

Generate changelog between two branches:

Sometimes you just need to show the changes made on acceptance since last production release. The following example would generate changelog with changes that are on acceptance branch and not yet in master.

generate-changelog master..acceptance

Generate changelog with releases info shown

generate-changelog --show-releases

Generate changelog between releases with releases info shown

generate-changelog 0.0.1..0.0.3 --show-releases

Generate changelog between branches with releases info shown

generate-changelog master..dev --show-releases

Generate changelog for the latest release with releases info shown

generate-changelog --latest-release --show-releases

Generate changelog with headings only (no commit messages) and releases info shown

generate-changelog --headings-only --show-releases

Generate changelog between two branches, show unreleased changes only:

generate-changelog master..acceptance --show-releases --unreleased-only

The following renderers are implemented:

• Markdown
• RestructuredText
• Historical Markdown (for compatibility with matyan versions prior to 0.4).

generate-changelog --show-releases --renderer=markdown

generate-changelog --show-releases --renderer=rest

generate-changelog --show-releases --renderer=historical-markdown

It's possible to fetch ticket title and description from Jira. In order for it to work, you should provide a fetch-title and fetch-description arguments.

The following needs to be added to your .matyan.ini:

[Settings]
fetchDataFrom=Jira

In addition to that, you should put valid Jira credentials into your global .matyan.ini configuration file.

Command to run:

generate-changelog --show-releases --fetch-title --fetch-description

Have in mind, that matyan shall be installed with jira option.

pip install matyan[jira]

Alternatively, make sure atlassian-python-api is installed.

pip install atlassian-python-api

See the output directory for examples.

Additionally see the Jupyter notebook examples.

In order to customize names and texts, add a .matyan.ini in your project directory, from which you will be running the generate-changelog command.

Sample configuration:

[BranchTypes]
feature: Feature
bugfix: Bugfix
hotfix: Hotfix
deprecation: Deprecation

[OtherBranchType]
other: Other

[Unreleased]
unreleased: Unreleased

[IgnoreCommits]
exact: more
       clean up
       code comments
       more on docs
       repo
       working
       more on
       wip
       commit
prefix: more on
        continue on

Note, that placing .matyan.ini into the home root will make that configuration global for all projects. That however could be handy, since local .matyan.ini files simply extend the global ones. For example, you could use global configuration for storing Jira credentials.

[Jira]
url:https://barseghyanartur.atlassian.net/
username:user@domain.com
token:abcd1234

Note, however, that sections are copied over entirely.

generate-changelog --show-releases 2>&1 | tee changelog.md

matyan-make-config

Simply type:

./runtests.py

Or use tox:

tox

Or use tox to check specific env:

tox -e py38

Sometimes checking logs could be handy. Matyan logs are stored in the directory, from which you are running the generate-changelog (or any other Matyan) command.

Update your .matyan.ini configuration in the following way:

[Settings]
debug=true

tail -f /path/to/your/project/matyan.log

If you want to modify current logging, use MATYAN_LOGGING_CONFIG environment variable.

Default configuration:

DEFAULT_LOGGING_CONFIG = {
    'version': 1,
    'disable_existing_loggers': False,
    'root': {
        'level': 'WARNING',
        'handlers': ['file'],
    },
    'formatters': {
        'verbose': {
            'format': '{levelname} {asctime} {module} {process:d} {thread:d} '
                      '{message}',
            'style': '{',
        },
        'simple': {
            'format': '{levelname} {message}',
            'style': '{',
        },
    },
    'handlers': {
        'console': {
            'level': 'WARNING',
            'class': 'logging.StreamHandler',
            'formatter': 'simple'
        },
        'file': {
            'level': 'WARNING',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': os.path.join(os.getcwd(), "matyan.log"),
            'maxBytes': 1048576,
            'backupCount': 99,
            'formatter': 'verbose',
        },
    },
    'loggers': {
        'matyan': {
            'handlers': ['file'],
            'propagate': True,
        },
    },
}
