Class GoloCompiler

java.lang.Object

org.eclipse.golo.compiler.GoloCompiler

public class GoloCompiler
extends java.lang.Object

The Golo compiler.

Instances of this class may be reused to compile several sources.

Several methods are made public while they do not necessarily need so for the needs of the Golo compiler. Such deviations from a "good and clean" design are on-purpose, as this facilitates the implementation of Golo support in IDEs.

Method Detail

setExceptionBuilder

public final void setExceptionBuilder(GoloCompilationException.Builder builder)

Initializes an ExceptionBuilder to collect errors instead of throwing immediately. This method is made public for the requirements of IDEs support.

Parameters:

builder - the exception builder to add problems into.

initParser

public final GoloParser initParser(java.lang.String goloSourceFilename,
                                   java.io.InputStream sourceCodeInputStream)
                            throws GoloCompilationException

Initializes a parser from an input stream. This method is made public for the requirements of IDEs support.

Parameters:

sourceCodeInputStream - the source code input stream.

Returns:

the parser.

Throws:

GoloCompilationException

initParser

public final GoloParser initParser(java.io.Reader sourceReader)

Initializes a parser from a reader. This method is made public for the requirements of IDEs support.

Parameters:

sourceReader - the source code reader.

Returns:

the parser.

compile

public final java.util.List<CodeGenerationResult> compile(java.lang.String goloSourceFilename,
                                                          java.io.InputStream sourceCodeInputStream)
                                                   throws GoloCompilationException

Compiles a Golo source file from an input stream, and returns a collection of results.

Parameters:

goloSourceFilename - the source file name.

sourceCodeInputStream - the source code input stream.

Returns:

a list of compilation results.

Throws:

GoloCompilationException - if a problem occurs during any phase of the compilation work.

getProblems

public java.util.List<GoloCompilationException.Problem> getProblems()

Returns the list of problems encountered during the last compilation

Returns:

a list of compilation problems.

compileTo

public final void compileTo(java.lang.String goloSourceFilename,
                            java.io.InputStream sourceCodeInputStream,
                            java.io.File targetFolder)
                     throws GoloCompilationException,
                            java.io.IOException

Compiles a Golo source file and writes the resulting JVM bytecode .class files to a target folder. The class files are written in a directory structure that respects package names.

Parameters:

goloSourceFilename - the source file name.

sourceCodeInputStream - the source code input stream.

targetFolder - the output target folder.

Throws:

GoloCompilationException - if a problem occurs during any phase of the compilation work.

java.io.IOException - if writing the .class files fails for some reason.

compileToJar

public final void compileToJar(java.lang.String goloSourceFilename,
                               java.io.InputStream sourceCodeInputStream,
                               java.util.jar.JarOutputStream jarOutputStream)
                        throws java.io.IOException

Compiles a Golo source fila and writes the resulting JVM bytecode .class files to a Jar file stream. The class files are written in a directory structure that respects package names.

Parameters:

goloSourceFilename - the source file name.

sourceCodeInputStream - the source code input stream.

jarOutputStream - the output Jar stream

Throws:

java.io.IOException - if writing the .class files fails for some reason.

GoloCompilationException

java.io.IOException

check

public final GoloModule check(ASTCompilationUnit compilationUnit)
