问题
We use lint in our codebase at work for C/C++, I'm trying to start integrating clang-format in my workflow as well.
Unfortunately, lint occasionally requires annotations to ignore a specific check, either of the format:
/*lint -[annotation] */
or
//lint -[annotation]
Specifically, if there's a space between the opening token for the comment and 'lint', it doesn't recognize it as an annotation directive. Unfortunately, the default settings I have for clang-format see that as an error and helpfully insert the space.
Is there any way to get clang-format to recognize comments matching that pattern and leave them alone? Right now I'm using 3.4, but could upgrade if needed.
回答1:
Clang-format has a `CommentPragmas' option that is
A regular expression that describes comments with special meaning, which should not be split into lines or otherwise changed.
When I put the following line in my .clang-format file, my Lint comments remain untouched.
CommentPragmas: '^lint'
Other comments that still have "lint" in them, but are not Lint comments still get formatted.

You can disable clang-format for that section of your file by using:
int formatted_code;
// clang-format off
void unformatted_code ;
// clang-format on
void formatted_code_again;
See the Disabling formating on a piece of code section.
