structDiagnostics;
Contains aggregated diagnostics information.
immutable uinterrors;
Number of errors diagnosed
immutable uintwarnings;
Number of warnings diagnosed
boolhasErrors() immutable;
Returns:
true if errors have been diagnosed
boolhasWarnings() immutable;
Returns:
true if warnings have been diagnosed
enumContractChecking: CHECKENABLE;
Indicates the checking state of various contracts.
default_
Initial value
disabled
Never do checking
enabled
Always do checking
enabledInSafe
Only do checking in@safe functions
structContractChecks;
Indicates which contracts should be checked or not.
ContractCheckingprecondition;
Precondition checks (in contract).
ContractCheckinginvariant_;
Invariant checks.
ContractCheckingpostcondition;
Postcondition checks (out contract).
ContractCheckingarrayBounds;
Array bound checks.
ContractCheckingassert_;
Assert checks.
ContractCheckingswitchError;
Switch error checks.
voiddeinitializeDMD();
Deinitializes the global variables of the DMD compiler.
This can be used to restore the state set byinitDMD to its original state.Useful if there's a need for multiple sessions of the DMD compiler in the sameapplication.
voidaddImport(const(char)[]path);
Add import path to theglobal.path.
Parameters:
const(char)[]pathimport to add
voidaddStringImport(const(char)[]path);
Add string import path toglobal.filePath.
Parameters:
const(char)[]pathstring import to add
stringfindDMDConfig(const(char)[]dmdFilePath);
Searches for admd.conf.
Parameters:
const(char)[]dmdFilePathpath to the current DMD executable
Returns:
full path to the founddmd.conf,null otherwise.
stringfindLDCConfig(const(char)[]ldcFilePath);
Searches for aldc2.conf.
Parameters:
const(char)[]ldcFilePathpath to the current LDC executable
Returns:
full path to the foundldc2.conf,null otherwise.
stringdetermineDefaultCompiler();
Detect the currently active compiler.
Returns:
full path to the executable of the found compiler,null otherwise.
autoparseImportPathsFromConfig(const(char)[]iniFile, const(char)[]execDir);
Parses admd.conf orldc2.conf config file and returns defined import paths.
Parameters:
const(char)[]iniFileiniFile to parse imports from
const(char)[]execDirdirectory of the compiler binary
Returns:
forward range of import paths found ininiFile
autofindImportPaths();
Finds admd.conf and parses it for import paths.This depends on the$DMD environment variable.If$DMD is set toldmd, it will try to detect and parse aldc2.conf instead.
Returns:
A forward range of normalized import paths.
