    • startGagging

      Declaration

      nothrow uint startGagging();

      Start ignoring compile errors instead of reporting them.

      Discussion

      Used for speculative compilation like __traits(compiles, XXX), but also internally to e.g. try out an alias this rewrite without comitting to it.

      Works like a stack, so N calls to startGagging should be paired with N calls to endGagging.

      Return Value

      the current number of gagged errors, which should later be passed to endGagging

    • endGagging

      Declaration

      nothrow bool endGagging(uint oldGagged);

      Stop gagging, restoring the old gagged state before the most recent call to startGagging.

      Parameters

      uint oldGagged

      the previous number of errors, as returned by startGagging

      Return Value

      true if errors occurred while gagged.

    • increaseErrorCount

      Declaration

      nothrow void increaseErrorCount();

      Increment the error count to record that an error has occurred in the current context.

      Discussion

      An error message may or may not have been printed.

    • deinitialize

      Declaration

      nothrow void deinitialize();

      Deinitializes the global state of the compiler.

      Discussion

      This can be used to restore the state set by _init to its original state.

    • versionNumber

      Declaration

      nothrow uint versionNumber();

      Return Value

      the version as the number that would be returned for __VERSION__

    • versionString

      Declaration

      nothrow string versionString();

      Return Value

      compiler version string.

    • versionChars

      Declaration

      nothrow const(char*) versionChars();

      Return Value

      compiler version as char string.

    • finalDefaultlibname

      Declaration

      const nothrow const(char)[] finalDefaultlibname();

      Return Value

      the final defaultlibname based on the command-line parameters

  • Loc

    Declaration

    struct Loc;

    A source code location

    Discussion

    Used for error messages, __FILE__ and __LINE__ tokens, __traits(getLocation, XXX), debug info etc.

    • filename

      Declaration

      const(char)* filename;

      zero-terminated filename string, either absolute or relative to cwd

    • linnum

      Declaration

      uint linnum;

      line number, starting from 1

    • charnum

      Declaration

      uint charnum;

      utf8 code unit index relative to start of line, starting from 1

    • initial

      Declaration

      static immutable Loc initial;

      use for default initialization of const ref Loc's

    • equals

      Declaration

      const nothrow bool equals(ref const(Loc) loc);

      Checks for equivalence by comparing the filename contents (not the pointer) and character location.

      Note:

      • Uses case-insensitive comparison on Windows
      • Ignores charnum if global.params.showColumns is false.

    • opEquals

      Declaration

      const pure nothrow @nogc @trusted bool opEquals(ref const(Loc) loc);
      const pure nothrow @trusted size_t toHash();

      opEquals() / toHash() for AA key usage

      Discussion

      Compare filename contents (case-sensitively on Windows too), not the pointer - a static foreach loop repeatedly mixing in a mixin may lead to multiple equivalent filenames (foo.d-mixin-<line>), e.g., for test/runnable/test18880.d.

    • isValid

      Declaration

      const pure nothrow bool isValid();

      Return Value

      true if Loc has been set to other than the default initialization
