Driver

dotty.tools.dotc.Driver
class Driver

Run the Dotty compiler.

Extending this class lets you customize many aspect of the compilation process, but in most cases you only need to call process on the existing object Main.

Concrete methods

def main(args: Array[String]): Unit
final def process(args: Array[String], simple: SimpleReporter | Null, callback: CompilerCallback | Null): ReporterResult

Entry point to the compiler that can be conveniently used with Java reflection.

Entry point to the compiler that can be conveniently used with Java reflection.

This entry point can easily be used without depending on the dotty package, you only need to depend on dotty-interfaces and call this method using reflection. This allows you to write code that will work against multiple versions of dotty without recompilation.

The trade-off is that you can only pass a SimpleReporter to this method and not a normal Reporter which is more powerful.

Usage example: https://github.com/lampepfl/dotty/tree/master/compiler/test/dotty/tools/dotc/InterfaceEntryPointTest.scala

Value parameters

args

Arguments to pass to the compiler.

callback

Used to execute custom code during the compilation process. No callbacks will be executed if this is null.

simple

Used to log errors, warnings, and info messages. The default reporter is used if this is null.

Attributes

final def process(args: Array[String], reporter: Reporter | Null, callback: CompilerCallback | Null): Reporter

Principal entry point to the compiler.

Principal entry point to the compiler.

Usage example: https://github.com/lampepfl/dotty/tree/master/compiler/test/dotty/tools/dotc/EntryPointsTest.scala.disabled in method runCompiler

Value parameters

args

Arguments to pass to the compiler.

callback

Used to execute custom code during the compilation process. No callbacks will be executed if this is null.

reporter

Used to log errors, warnings, and info messages. The default reporter is used if this is null.

Attributes

Returns

The Reporter used. Use Reporter#hasErrors to check if compilation succeeded.

def process(args: Array[String]): Reporter

Entry point to the compiler with no optional arguments.

Entry point to the compiler with no optional arguments.

This overload is provided for compatibility reasons: the RawCompiler of sbt expects this method to exist and calls it using reflection. Keeping it means that we can change the other overloads without worrying about breaking compatibility with sbt.

Attributes

def process(args: Array[String], rootCtx: Context): Reporter

Entry point to the compiler using a custom Context.

Entry point to the compiler using a custom Context.

In most cases, you do not need a custom Context and should instead use one of the other overloads of process. However, the other overloads cannot be overridden, instead you should override this one which they call internally.

Usage example: https://github.com/lampepfl/dotty/tree/master/compiler/test/dotty/tools/dotc/EntryPointsTest.scala.disabled in method runCompilerWithContext

Value parameters

args

Arguments to pass to the compiler.

rootCtx

The root Context to use.

Attributes

Returns

The Reporter used. Use Reporter#hasErrors to check if compilation succeeded.

def setup(args: Array[String], rootCtx: Context): Option[(List[AbstractFile], Context)]

Setup context with initialized settings from CLI arguments, then check if there are any settings that would change the default behaviour of the compiler.

Setup context with initialized settings from CLI arguments, then check if there are any settings that would change the default behaviour of the compiler.

Attributes

Returns

If there is no setting like -help preventing us from continuing compilation, this method returns a list of files to compile and an updated Context. If compilation should be interrupted, this method returns None.
