This is my take on a couple of these - most likely the combination of how the convention was explained to me when I started work on LLDB, and then a few years of me adjusting to it, with varied success. To be taken with a grain of salt, or two.

Most > function-declaration comments seem to wrap at 80) I don’t think there is an explicit column limit. That’s not to be taken as 300 columns being OK, but we are also not as strict as the rest of LLVM on a specific number. I tend to wrap my function declarations when they have a lot of arguments, not so much for column limits, but for readability. I also have a penchant for grouping options in option classes, but that’s just my personal taste, not a guideline. > Brace style: Allman > if (foo) > { > // code here > } > I sometimes get away with if (foo) oneLineHere(); but yes, braces on separate line - and I believe there actually is a preference for erring on the side of having braces even in the one statement case. > Break after function return type: Always, only on declarations, only on > definitions, only in headers, or never? > > Space before function parentheses: When? I do both always. Or rather, the first I do always. The second, I tend to do it at declarations/definitions - a little less religiously at call sites As a post-hoc rationalization, that makes it easier to look for function definitions vs usages, i.e. look for ‘Foo (‘ if you want to see where Foo is defined, for ‘Foo(‘ to see where Foo is used In practice, I think there is enough variety in this regard that this will fail more often than it works > > Indent case labels inside switch: A or B below? > switch (foo) > { > case A: > case B: > } > > Indent braces inside of a case: A or B below? > switch (foo) > { > case A: > { > } > case B: > { > } > } > > Any other rules I should be cognizant of? Well, the obvious; member variables start with an m_, globals with g_, class and function names start with uppercase letters, and then go SomewhatLikeThisYouSee, member variables go instead m_likeThisForVariables. > _______________________________________________ > lldb-dev mailing list > lldb-dev@cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/lldb-dev Thanks, - Enrico 📩 egranata@.com ☎️ 27683
