DiagnosticHandler alias DiagnosticHandler = bool delegate(const ref Loc location, Color headerColor, const(char)* header, const(char)* messageFormat, va_list args, const(char)* prefix1, const(char)* prefix2): The type of the diagnostic handler see verrorReport for arguments
FatalErrorHandler alias FatalErrorHandler = bool delegate(): The type of the fatal error handler

Classes

ErrorSinkCompiler class ErrorSinkCompiler: Error message sink for D compiler.

Enums

Classification enum Classification: Color highlighting to classify messages
ErrorKind enum ErrorKind: Constants used to discriminate kinds of error messages.
HIGHLIGHT enum HIGHLIGHT: Embed these highlighting commands in the text stream. HIGHLIGHT.Escape indicates a Color follows.

Functions

deprecation void deprecation(Loc loc, const(char)* format, ...): Print a deprecation message, may increase the global warning or error count depending on whether deprecations are ignored.
deprecationSupplemental void deprecationSupplemental(Loc loc, const(char)* format, ...): Print additional details about a deprecation message. Doesn't increase the error count, or print an additional deprecation prefix.
error void error(Loc loc, const(char)* format, ...): Print an error message, increasing the global error count.
error 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.
errorSupplemental void errorSupplemental(Loc loc, const(char)* format, ...): Print additional details about an error message. Doesn't increase the error count or print an additional error prefix.
fatal 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.
halt void halt(): Try to stop forgetting to remove the breakpoints from release builds.
message void message(Loc loc, const(char)* format, ...): Print a verbose message. Doesn't prefix or highlight messages.
message void message(const(char)* format, ...): Same as above, but doesn't take a location argument.
tip void tip(const(char)* format, ...): Print a tip message with the prefix and highlighting.
verrorReport void verrorReport(Loc loc, const(char)* format, va_list ap, ErrorKind kind, const(char)* p1, const(char)* p2): 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.
verrorReportSupplemental void verrorReportSupplemental(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.
warning void warning(Loc loc, const(char)* format, ...): Print a warning message, increasing the global warning count.
warningSupplemental void warningSupplemental(Loc loc, const(char)* format, ...): Print additional details about a warning message. Doesn't increase the warning count or print an additional warning prefix.

Static variables

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