[clang-format] Respect spaces in line comment section without an active column limit

Authored by HazardyKnusperkeks on Feb 17 2021, 1:19 PM.



Before line comments were not touched at all with ColumnLimit == 0, so this is a real change. But at least for me it was unexpected that the comments were not fixed with ColumnLimit == 0.

It seems to be a bug indeed.
So, basically all the changes are just adding a bunch of conditions on ColumnLimit != 0 which is a special value meaning "no limit", right? Or have I missed something?
Thining out loud... wouldn't it be easier to change ColumnLimit from 0 to numeric_limits<unsigned>::max() just before these transformations?


Is this condition on ColumnLimit (and other below) working ok when ColumnLimit == 0? Do your tests cover it?

I must admit, that I don't know for sure.
Line comments should be checked, and a string literal on one line is also covered (that's how I found that I have to disable the inner loop). I should add a new test case with multiline comments and multiline string literals.

But I think your proposal of using ::max() is sound and should be used.

  • Work with ::max instead of many checks for == 0.
  • Additional Testcase
