nothrow void error(ref const Loc loc, const(char)* format, ...);
Print an error message, increasing the global error count.
Parameters:
Loc loc location of error
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void error(Loc loc, const(char)* format, ...);
Same as above, but allows Loc() literals to be passed.
Parameters:
Loc loc location of error
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void error(const(char)* filename, uint linnum, uint charnum, const(char)* format, ...);
Same as above, but takes a filename and line information arguments as separate parameters.
Parameters:
const(char)* filename source file of error
uint linnum line in the source file
uint charnum column number on the line
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void errorSupplemental(ref const Loc loc, const(char)* format, ...);
Print additional details about an error message. Doesn't increase the error count or print an additional error prefix.
Parameters:
Loc loc location of error
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void warning(ref const Loc loc, const(char)* format, ...);
Print a warning message, increasing the global warning count.
Parameters:
Loc loc location of warning
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void warningSupplemental(ref const Loc loc, const(char)* format, ...);
Print additional details about a warning message. Doesn't increase the warning count or print an additional warning prefix.
Parameters:
Loc loc location of warning
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void deprecation(ref const Loc loc, const(char)* format, ...);
Print a deprecation message, may increase the global warning or error count depending on whether deprecations are ignored.
Parameters:
Loc loc location of deprecation
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void deprecationSupplemental(ref const Loc loc, const(char)* format, ...);
Print additional details about a deprecation message. Doesn't increase the error count, or print an additional deprecation prefix.
Parameters:
Loc loc location of deprecation
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void message(ref const Loc loc, const(char)* format, ...);
Print a verbose message. Doesn't prefix or highlight messages.
Parameters:
Loc loc location of message
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void message(const(char)* format, ...);
Same as above, but doesn't take a location argument.
Parameters:
const(char)* format printf-style format specification
... printf-style variadic arguments
alias DiagnosticHandler = bool delegate(ref const(Loc) location, Color headerColor, const(char)* header, const(char)* messageFormat, __va_list_tag* args, const(char)* prefix1, const(char)* prefix2) nothrow;
The type of the diagnostic handler see verrorPrint for arguments
Returns:
true if error handling is done, false to continue printing to stderr
DiagnosticHandler diagnosticHandler;
The diagnostic handler. If non-null it will be called for every diagnostic message issued by the compiler. If it returns false, the message will be printed to stderr as usual.
nothrow void tip(const(char)* format, ...);
Print a tip message with the prefix and highlighting.
Parameters:
const(char)* format printf-style format specification
... printf-style variadic arguments
nothrow void verror(ref const Loc loc, const(char)* format, va_list ap, const(char)* p1 = null, const(char)* p2 = null, const(char)* header = "Error: ");

Parameters:
Loc loc location of error
const(char)* format printf-style format specification
va_list ap printf-style variadic arguments
const(char)* p1 additional message prefix
const(char)* p2 additional message prefix
const(char)* header title of error message
