mafw.devtools.release

Release management utilities for MAFw development tools.

This package provides business logic for version bumping, changelog generation, release note creation, and git workflow operations during the release process.

class mafw.devtools.release.DeprecatedOption(*args: Any, deprecated_message: str = '', **kwargs: Any)[source]

Bases: Option

A Click Option subclass that emits a DeprecationWarning when explicitly used.

Use this class as cls=DeprecatedOption in a @click.option decorator to mark an option as deprecated. The warning is only emitted when the user explicitly provides the option on the command line; default-value resolution does not trigger the warning. The resolved value is passed through to the command callback unchanged.

Parameters:: deprecated_message (str) – Warning text emitted when the option is explicitly provided on the command line.

Added in version 2.2.

consume_value(ctx: Context, opts: Mapping[str, Parameter]) → tuple[Any, ParameterSource][source]

Intercept value consumption to detect explicit CLI usage.

Parameters:

ctx (click.Context) – Current Click context.
opts (Mapping[str, click.Parameter]) – Parsed option tokens from the command line.

Returns:

Tuple of (value, source) as returned by the parent implementation.

Return type:

tuple[Any, click.core.ParameterSource]

class mafw.devtools.release.DocTargetVersionPrompt(*args: Any, min_version: str | None = None, **kwargs: Any)[source]

Bases: Prompt

Prompt that validates documentation target versions in major.minor form.

Initialize the prompt with an optional minimum allowed version.

Parameters:: min_version (str | None) – Lowest allowed documentation target version in major.minor form.

process_response(value: str) → str[source]

Validate and normalize the documentation target version entered by the user.

Parameters:: value (str) – Raw user input.
Returns:: Normalized version string.
Return type:: str
Raises:: InvalidResponse – If the value does not match major.minor or is below the minimum.

validate_error_message = 'Please enter a version in major.minor form, for example 2.4.': Message shown when the entered documentation target version is invalid.

mafw.devtools.release.bump_version(segment: str, *, dry_run: bool) → str[source]

Compute or execute the version bump depending on dry-run mode.

Hatch is used as single source of truth for the resolved target version. In dry-run mode, the __about__.py file is temporarily rewritten by Hatch and restored afterwards so the git worktree remains unchanged.

Parameters:

segment (str) – Hatch selector segments (comma-separated).
dry_run (bool) – Whether command execution is disabled.

Returns:

New version string.

Return type:

str

mafw.devtools.release.check_main_branch() → None[source]

Raises:: DevtoolsError – If the current branch is not main.

mafw.devtools.release.check_missing_release(current_version: str) → None[source]

Prevent creating a new release when a stable release is already missing a tag.

Parameters:: current_version (str) – Current project version.
Raises:: DevtoolsError – If a missing stable release is detected.

mafw.devtools.release.classify_version(version: str) → Literal['stable', 'rc', 'alpha', 'beta'][source]

Classify a version string into stable/rc/alpha/beta.

Parameters:: version (str) – Version string to classify.
Returns:: Classified version kind.
Return type:: str
Raises:: DevtoolsError – If the version cannot be parsed.

mafw.devtools.release.commit_changes(version: str, dry_run: bool, *, include_changelog: bool = True) → None[source]

Commit tracked release artifacts for the target version.

Parameters:

mafw.devtools.release.create_release_note(version: str, dry_run: bool) → Path[source]

Create the release note markdown file for the given version.

Change sections are copied from the generated changelog for the same version to ensure release notes stay aligned with changelog content.

Parameters:

dry_run (bool) – Whether command execution is disabled.

Returns:

Path to the release note markdown file.

Return type:

Path

Raises:

The parsing logic expects the block to contain level-3 headings (###) with standardized labels (e.g. “New Features”, “Bug Fixes”, …).

Parameters:: changelog_block (str) – Changelog markdown block to parse.
Returns:: Mapping from release-note category key to markdown content.
Return type:: dict[str, str]
