changelog-gen 0.8.1

Changelog generation tool

Changelog Generator - v0.8.1

changelog-gen is a CHANGELOG generator intended to be used in conjunction with bumpversion to generate changelogs and create release tags.

Installation

pip install changelog-gen

or clone this repo and install with poetry.

poetry install

Usage

changelog-gen currently only supports reading changes from a release_notes folder.

Files in the folder should use the format {issue_number}.{type}.

By default supported types are currently fix and feat. Additional types can be configured to map to these initial types.

The contents of each file is used to populate the changelog file. If the type ends with a ! it denotes a breaking change has been made, this will lead to a major release being suggested.

$ ls release_notes
  4.fix  7.fix

$ changelog-gen

## v0.2.1

Configuration

Of the command line arguments, most of them can be configured in setup.cfg to remove the need to pass them in every time.

Example setup.cfg:

[changelog_gen]
commit = true
release = true
allow_dirty = false

Configuration file -- Global configuration

General configuration is grouped in a [changelog_gen] section.

commit = (True | False)

[optional]
default: False

Commit changes to the changelog after writing.

Also available as --commit (e.g. changelog-gen --commit)

release = (True | False)

[optional]
default: False

Use bumpversion to tag the release

Also available as --release (e.g. changelog-gen --release)

allow_dirty = (True | False)

[optional]
default: False

Don't abort if the current branch contains uncommitted changes

Also available as --allow-dirty (e.g. changelog-gen --allow-dirty)

issue_link =

[optional]
default: None

Create links in the CHANGELOG to the originating issue. A url that contains an {issue_ref} for formatting.

Example:

[changelog_gen]
issue_link = http://github.com/EdgyEdgemond/changelog-gen/issues/{issue_ref}

date_format =

[optional]
default: None

Add a date on the version line, use strftime and strptime format codes. The format string can include any character, a space is included between the version tag and the date tag.

When using in setup.cfg be sure to protect the % signs (see example below) and be mindful about spacing as the string is taken straight from the = sign.

Also available as --date-format (e.g. --date-format '%Y-%m-%d').

Example:

[changelog_gen]
date_format =on %%Y-%m-%d

allowed_branches =

[optional]
default: None

Prevent changelog being generated if the current branch is not in the supplied list. By default all branches are allowed.

Example:

[changelog_gen]
allowed_branches =
  master
  develop

sections =

[optional]
default: None

Define custom headers or new sections/headers, new sections will require a matching section_mapping configuration.

Example:

[changelog_gen]
sections =
  feat=New Features
  change=Changes
  remove=Removals
  fix=Bugfixes

section_mapping =

[optional]
default: None

Configure additional supported release_note extensions to supported changelog sections.

Example:

[changelog_gen]
section_mapping =
  test=fix
  bugfix=fix
  docs=fix
  new=feat

post_process =

[optional]
default: None

Configure a REST API to contact when a release is made

See example on Jira configuration information.

.url=
[required]
default: None
The url to contact. Can have the variables {issue_ref} and {new_version}.

.verb=
[optional]
default: POST
HTTP method to use.

.body=
[optional]
default: {{"body": "Released on v{new_version}"}}
The text to send to the API. Can have the variables {issue_ref} and {new_version}.

.auth_env =
[optional]
default: None
Name of the environment variable to use to extract the basic auth information to contact the API. The content of the variable should be {user}:{api key}.

Example to post to JIRA:

[changelog_gen]
post_process =
  url=https://your-domain.atlassian.net/rest/api/2/issue/ISSUE-{issue_ref}/comment
  verb=POST
  body={{"body": "Released on v{new_version}"}}
  auth_env=JIRA_AUTH

This assumes an environment variable JIRA_AUTH with the content [e-mail]:{api_key}. See manage-api-tokens-for-your-atlassian-account to generate a key.

Note: spaces around = will not be stripped, be sure to use <field>=<value>.

Also partially available as --post-process-url and --post-process-auth-env (e.g. changelog-gen --post-process-url 'http://my-api-url.domain/comment{issue_ref}' --post-process-auth-env MY_API_AUTH)
