bugprone-argument-comment¶
Checks that argument comments match parameter names.
The check understands argument comments in the form /*parameter_name=*/
that are placed right before the argument.
void f(bool foo);
...
f(/*bar=*/true);
// warning: argument name 'bar' in comment does not match parameter name 'foo'
The check tries to detect typos and suggest automated fixes for them.
Options¶
-
StrictMode
¶
When zero (default value), the check will ignore leading and trailing underscores and case when comparing names – otherwise they are taken into account.
-
CommentBoolLiterals
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the boolean literal argument.
Before:
void foo(bool TurnKey, bool PressButton);
foo(true, false);
After:
void foo(bool TurnKey, bool PressButton);
foo(/*TurnKey=*/true, /*PressButton=*/false);
-
CommentIntegerLiterals
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the integer literal argument.
Before:
void foo(int MeaningOfLife);
foo(42);
After:
void foo(int MeaningOfLife);
foo(/*MeaningOfLife=*/42);
-
CommentFloatLiterals
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the float/double literal argument.
Before:
void foo(float Pi);
foo(3.14159);
After:
void foo(float Pi);
foo(/*Pi=*/3.14159);
-
CommentStringLiterals
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the string literal argument.
Before:
void foo(const char *String);
void foo(const wchar_t *WideString);
foo("Hello World");
foo(L"Hello World");
After:
void foo(const char *String);
void foo(const wchar_t *WideString);
foo(/*String=*/"Hello World");
foo(/*WideString=*/L"Hello World");
-
CommentCharacterLiterals
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the character literal argument.
Before:
void foo(char *Character);
foo('A');
After:
void foo(char *Character);
foo(/*Character=*/'A');
-
CommentUserDefinedLiterals
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the user defined literal argument.
Before:
void foo(double Distance);
double operator"" _km(long double);
foo(402.0_km);
After:
void foo(double Distance);
double operator"" _km(long double);
foo(/*Distance=*/402.0_km);
-
CommentNullPtrs
¶
When true, the check will add argument comments in the format
/*ParameterName=*/
right before the nullptr literal argument.
Before:
void foo(A* Value);
foo(nullptr);
After:
void foo(A* Value);
foo(/*Value=*/nullptr);
