git-autofixup is a Git helper that automatically generates fixup commits for changes made on a topic branch. It helps developers incorporate corrections into earlier commits while preserving a logical and readable history.
During feature development, it is common to revisit code introduced in earlier commits. A developer may correct a mistake, adjust an implementation or respond to review feedback after several additional changes have already been committed.
Without assistance, organising these corrections involves identifying the appropriate original commits and preparing individual fixup commits. git-autofixup reduces that manual work by examining changes in the working directory and using Git’s blame information to determine their likely origins.
The utility analyses changes as individual diff hunks, allowing modifications affecting different earlier commits to be handled separately. It also provides controls over how confidently a change must be associated with a previous commit.
Generated fixup commits can subsequently be incorporated into the original commits through Git’s interactive rebase and autosquash functionality.
This is free and open source software.
Key Features
- Automatically generates fixup commits for modifications on topic branches.
- Uses git diff to analyse individual hunks of changed code.
- Uses git blame to associate modified lines with earlier commits.
- Can create multiple fixup commits when changes belong to different commits.
- Restricts candidate commits to a specified revision range.
- Automatically determines a suitable base revision from upstream tracking information when available.
- Processes only staged changes when modifications have been added to the Git index.
- Supports path filtering to restrict processing to selected files.
- Provides configurable strictness levels for assigning changes to earlier commits.
- Avoids assigning changes when the relationship to an earlier commit is insufficiently clear.
- Uses a temporary index when creating the generated commits.
- Integrates with Git’s interactive rebase and autosquash workflow.
- Provides verbosity options for examining how changes are processed.
