So you want to help with WebKit?

Blog post by PulkoMandy on Fri, 2024-03-01 12:00

This blog post was originally a forum post. It is reproduced here on the website to make it easier to find and reference. I heard that some more people may be interesting in helping with WebKit. So here is a summary of the current state, the things I think need work, or the possible future paths to explore. Keeping WebKitLegacy up and running The Web moves fast these days. So we have to stay very up to date with upstream WebKit.

RFC Coding Guidelines: Formatting Class Member Declarations

Blog post by nielx on Mon, 2024-02-05 16:13

This RFC proposes to change the Haiku coding guidelines to change the formatting of variable and member declarations from a Table Class Member Declaration Style, to a Normalized Declaration Style or a Aligned Declaration Style. The arguments are that (1) the current format has severe limitations which limits the aesthetic value of the current formatting, especially when modern C++ language features are used, and (2) it is not a good use of the time of Haiku’s contributors to modify and maintain custom logic in the haiku-format tool (derived from clang-format). If the proposal is adopted, any new code contributions will have to use the new formatting style, and contributors are required to reformat any declarations that they modify.

This is the first article on this topic, but it may become a regular (quarterly?) series. Let me know in the comments what you find of these notes, and what else you think should be covered.
