The key intent behind password comment will be to ensure that the overall password health off Google’s code base is improving more than go out.

Earliest, designers will be able to build progress on their opportunities. For people who never ever fill in an update towards codebase, then your codebase never enhances. And additionally, when the a customer will make it very difficult the switch to enter, then designers was disincentivized and work out improvements subsequently.

Concurrently, it will be the obligation of the customer in order that for every CL try of these a quality that the full code health of its codebase isn’t decreasing down the road. This might be challenging, given that will, codebases degrade as a result of small decreases during the password health over the years, especially when a group is below extreme big date limitations and they think they need to bring shortcuts to accomplish their requires.

And additionally, a customer has actually ownership and you can obligations across the code he could be examining. They want to make sure the codebase stays uniform, maintainable, and all of additional love ru something stated for the “What to look out for in a code comment.”

Generally, reviewers is choose granting an effective CL after it’s within the a good condition where it will be enhances the complete code health of your own program getting worked on, even if the CL actually finest.

You can find limits to that particular, of course. Eg, if the an excellent CL contributes an element the customer doesn’t want inside their system, then the customer can easily refute acceptance even when the code is actually well-tailored.

A significant factor we have found that there’s no such as for example matter because the “perfect” code-there clearly was merely best password. Reviewers shouldn’t need the creator so you’re able to shine all lightweight piece out-of an effective CL just before giving approval. As an alternative, the new reviewer would be to stabilize the need to make forward advances as compared to requirement for the alterations he is suggesting. Rather than seeking to excellence, just what a reviewer is always to find try carried on improvement. A great CL you to definitely, overall, improves the maintainability, readability, and understandability of one’s system must not be defer for days otherwise days as it isn’t really “perfect.”

Writers should please get off statements stating you to anything is most useful, however, if it isn’t very important, prefix it which have something similar to “Nit: “ so that the writer remember that it’s just a question of shine which they you certainly will like to forget about.

Note: Absolutely nothing within this document justifies checking inside the CLs that needless to say worsen the general password wellness of one’s system. The only go out you might do this will be when you look at the an enthusiastic crisis.


Code opinion might have a significant function of knowledge builders anything brand new about a code, a build, otherwise standard app design principles. It’s always great to go away comments that help a designer understand new stuff. Sharing education is part of improving the code health out of an effective system through the years. Only just remember that , in case the remark are purely instructional, although not critical to appointment the standards described contained in this document, prefix they with “Nit: “ if not signify it is really not compulsory towards creator so you can take care of they within CL.


For the issues of fashion, the style book is the natural authority. People purely concept section (whitespace, etcetera.) that is not throughout the layout guide is an issue of personal preference. The style is consistent with what exactly is here. If there is zero earlier in the day layout, deal with new author’s.

Aspects of app build are practically never ever an absolute build thing or simply just an individual liking. He is centered on root prices and should become considered towards the those standards, besides because of the private view. Possibly there are a few legitimate selection. In the event the creator can demonstrated (either as a result of data otherwise predicated on strong systems values) one multiple steps try just as legitimate, then customer is undertake the newest preference of your own publisher. If you don’t the choice is determined from the simple prices away from app structure.
