Version unspecified
OS Windows NT

Extended Description

Detect when C-style /.../ block comments are used to create a single-line comment. Replace those block-style comments with // style comments.

Possible false positives:

/* ....\ */

comments could result in a // comment like this:

// ...\

which would escape the newline and be a problem.

研究方向
The issue proposes a clang tidy check to replace C style single line block comments with // comments. Implementation requires creating a new check using AST matchers. Review existing checks in clang tidy for patterns, e.g., in clang tools extra/clang tidy/. Special attention needed for the false positive case where /* ...\ */ could become // ...\ and break line continuation. Start by examining the comment related checks and understanding the Lexer or SourceManager APIs for comment detection.
