如何配置clang-format使宏定义的函数声明保持逐行显示

Alright, I've got you covered here. The key is to tell clang-format that your DECL_DigOut macro should be treated as a standalone statement—this way, it'll automatically break each invocation onto its own line.

Here's how to do it:

1. Update your .clang-format configuration
   Add the StatementMacros option to your config file, and include DECL_DigOut in the list. This tells clang-format to treat calls to this macro as individual statements, just like regular function calls or variable declarations.

   Example .clang-format snippet:

   # Other existing config options...
   StatementMacros:
     - DECL_DigOut
   

2. Run clang-format again
   With this change, your problematic line of consecutive DECL_DigOut calls will be formatted to:

   DECL_DigOut(LED0, 4, 23, 0)
   DECL_DigOut(LED1, 4, 25, 0)
   DECL_DigOut(MAIN_HW0, 3, 14, 0)
   DECL_DigOut(MAIN_HW1, 3, 15, 0)
   DECL_DigOut(MAIN_HW2, 3, 16, 0)
   

Why this works #

The StatementMacros list identifies macros that act as statements (even if they don't end with a semicolon). Clang-format will then apply statement-level formatting rules to them, including breaking each invocation onto a new line instead of keeping them all in one line.

If you have other similar macros (like DECL_GPO if you ever call it directly), you can add those to the StatementMacros list too to get the same behavior.
