Fluctuating between “fun” and “frustrating,” this approach eventually yields good results, but it’s far from efficient. Alternatively, they’ll remember some vague details and simply assume earlier commits properly set up later ones, failing to identify potential issues.īut how does a scatterbrained narrative hurt the developer? A developer’s first instinct when working on a new project is often to hack on it until they get something functional. To ensure earlier commits properly set up later ones (for example, verifying a newly-created function is used properly), the reviewer ultimately needs to piece together the narrative on their own for each commit, figure out which earlier changes establish the relevant background context and tediously click back and forth between them.

If those commits do not tell a singular, easy-to-follow story, the reviewer will need to context-switch as the author’s commits jump from topic to topic. Reviewing commit-by-commit is the easiest way to avoid being overwhelmed by the changes in a sufficiently large pull request. The problemĭisorganized commits that eschew a clear narrative will affect two people: the reviewer, and the developer themself.

#Git commit comment series#

Like your favorite novel, a series of commits has a narrative structure that contextualizes the “plot” of your change with the code. Although you may naturally incorporate them into your development process with practice, each can be applied iteratively after you’ve written all of your code. The guidelines below are presented to help you utilize that creative voice to make your commits effective tools of communication.Īs you read these guidelines, don’t worry about how you’ll be able to utilize all of this advice in the midst of writing code.

Software development involves a lot of creativity, so your commits will reflect the context of your changes, your goals, and your personal style.

Describe some of the practical applications of a well-crafted commit history.

Outline pragmatic approaches for applying those guidelines.

Introduce some guidelines for organizing and revising commits.

It’s been my experience that commits are most effective when they’re tweaked and polished to deliberately convey a message to their audiences: reviewers, other contributors, and even your future self. They even come with human-readable messages! As a result, a repository’s commit history is the best tool a developer can use to explain and understand code.

Over time, commits should tell a story of the history of your repository and how it came to be the way that it currently is.Ĭommits are a firsthand historical record of exactly how and why each line of code came to be. are snapshots of your entire repository at specific times…based around logical units of change. Luckily, the tools needed to solve these problems have been here all along!Ĭommits in Git repositories are more than just save points or logs of incremental progress in a larger project. While there are ways to mitigate these issues (code comments, style guides, documentation requirements), we still inevitably find ourselves spending hours on just trying to understand code. These questions all reflect the limitations of collaboratively-developed source code as a communication medium. This pull request is massive, where do I start?.Is this comment out-of-date? I don’t think it describes what I’m seeing.How often have you found yourself thinking:
