Add Header Guard

Add Header Guard/Amend Header Guard can be found in the Source Actions... menu.

The Add Header Guard command adds a header guard to the current header file. Based on the Header Guard: Style setting, C-mantic will insert either a conditional #define block, #pragma once, or both. #define names are generated based on the setting Header Guard: Define Format.

If the file already has a header guard that does not match your configured style, then the Add Header Guard command will “amend” the existing one to match your configuration. Additionally, if you select the header guard with your cursor, then Amend Header Guard will be suggested as a Quick Fix.
