<div dir="ltr">Hi,<div><br></div><div>motivated by the current libsecurity_ssl brouhaha, I experimented with giving clang a -Windent that warns on strange indent. For performance and other reasons, it it only compares the indent of the first statement after a non-composite if/for/while with the indent of the if/for/while itself, and warns if the statement following the if/for/while (not the child of the if/for/while, but the statement after that) has a higher indent than the if/for/while. So it'd warn on this:</div>
<div><br></div><div> if (1)</div><div> do_stuff();</div><div> do_stuff(); // Has higher indent than the if</div><div><br></div><div>This works better than I thought it would – I tried it on chromium, and while it fires quite a bit, when it fires it's justified most of the time. It's probably too loud to be enabled by default, but it should do well in nicely-formatted codebases such as llvm, webkit, chromium's non-third-party code, etc.</div>
<div><br></div><div>I'm away for the next week, but maybe someone wants to pick it up. The patch and many code snippets that are tricky are in <a href="http://llvm.org/bugs/show_bug.cgi?id=18938">http://llvm.org/bugs/show_bug.cgi?id=18938</a> .</div>
