nothrow void error(const ref 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(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(const ref 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(const ref 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(const ref 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(const ref 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(const ref 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(const ref 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 verrorReport 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 verrorReport(const ref Loc loc, const(char)* format, va_list ap, ErrorKind kind, const(char)* p1 = null, const(char)* p2 = null);

Implements error, warning, deprecation, message, and tip. Report a diagnostic error, taking a va_list parameter, and optionally additional message prefixes. Whether the message gets printed depends on runtime values of DiagnosticReporting and global gagging.

Parameters:

Loc loc	location of error
const(char)* format	printf-style format specification
va_list ap	printf-style variadic arguments
ErrorKind kind	kind of error being printed
const(char)* p1	additional message prefix
const(char)* p2	additional message prefix

nothrow void verrorReportSupplemental(const ref Loc loc, const(char)* format, va_list ap, ErrorKind kind);

Implements errorSupplemental, warningSupplemental, and deprecationSupplemental. Report an addition diagnostic error, taking a va_list parameter. Whether the message gets printed depends on runtime values of DiagnosticReporting and global gagging.

Parameters:

Loc loc	location of error
const(char)* format	printf-style format specification
va_list ap	printf-style variadic arguments
ErrorKind kind	kind of error being printed

alias FatalErrorHandler = bool delegate() nothrow;

The type of the fatal error handler

Returns:

true if error handling is done, false to do exit(EXIT_FAILURE)

FatalErrorHandler fatalErrorHandler;

The fatal error handler. If non-null it will be called for every fatal() call issued by the compiler.

nothrow void fatal();

Call this after printing out fatal error messages to clean up and exit the compiler. You can also set a fatalErrorHandler to override this behaviour.

nothrow @safe void halt();

Try to stop forgetting to remove the breakpoints from release builds.

enum HIGHLIGHT: ubyte;

Embed these highlighting commands in the text stream. HIGHLIGHT.Escape indicates a Color follows.
