clang-format破坏了lint注释 [英] clang-format breaks lint annotations

问题描述

在C/C ++的工作中，我们在代码库中使用了lint，我也在尝试将clang格式集成到我的工作流中.

We use lint in our codebase at work for C/C++, I'm trying to start integrating clang-format in my workflow as well.

不幸的是，皮棉偶尔需要使用注释来忽略特定的检查，格式如下:

Unfortunately, lint occasionally requires annotations to ignore a specific check, either of the format:

/*lint -[annotation] */

或

//lint -[annotation]

具体来说，如果注释的开始标记和'lint'之间有空格，则不会将其识别为注释指令.不幸的是，我为clang-format设置的默认设置将其视为错误并有益地插入了空格.

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.

是否有任何方法可以让clang格式识别与该模式匹配的注释并将其保留?现在我正在使用3.4，但可以根据需要进行升级.

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.

推荐答案

Clang格式的"CommentPragmas"选项为

Clang-format has a `CommentPragmas' option that is

描述具有特殊含义的注释的正则表达式，不应将其拆分成几行或进行其他更改.

A regular expression that describes comments with special meaning, which should not be split into lines or otherwise changed.

当我在.clang格式的文件中添加以下行时，我的Lint注释保持不变.

When I put the following line in my .clang-format file, my Lint comments remain untouched.

CommentPragmas:  '^lint'

其他注释中仍然包含"lint"但不是Lint的注释仍会被格式化.

Other comments that still have "lint" in them, but are not Lint comments still get formatted.
