Hi,

I've read, that it is possible from M8 on to use the AST independently.
Trying "AST ast = new AST()" does not work because of dependencies.

Could someone give me some link with the description of how to set up
the use of the AST outside of a plugin.

TIA

Frank

It doesn't work outside of a plugin, because it requires JavaCore
plugin to be initialized.

The following code runs untill the end, without initialized JavaCore.

How can I put the CompilationUnit into a file?

Frank

Hashtable hashtable = new Hashtable();
hashtable.put("org.eclipse.jdt.core.compiler.source","1.4 ");
AST ast = new AST(hashtable);
CompilationUnit unit = ast.newCompilationUnit();
PackageDeclaration mrk = ast.newPackageDeclaration();
mrk.setName(ast.newSimpleName("mrk"));
unit.setPackage(mrk);
ImportDeclaration imp_fo_core = ast.newImportDeclaration();
imp_fo_core.setName(ast.newQualifiedName(
ast.newSimpleName("fo"),
ast.newSimpleName("core")) );
imp_fo_core.setOnDemand(true);
unit.imports().add(imp_fo_core);
TypeDeclaration myType = ast.newTypeDeclaration();
myType.setInterface(false);
myType.setModifiers(Modifier.PUBLIC);
myType.setName(ast.newSimpleName("MyType"));
MethodDeclaration method_1 = ast.newMethodDeclaration();
method_1.setConstructor(false);
method_1.setModifiers(Modifier.PUBLIC);
method_1.setName(ast.newSimpleName("actionWriteMessage"));
method_1.setReturnType(ast.newPrimitiveType(PrimitiveType.VO ID));
Block block = ast.newBlock();
MethodInvocation invoc_1 = ast.newMethodInvocation();
invoc_1.setExpression(ast.newQualifiedName(
ast.newSimpleName("System"),
ast.newSimpleName("out")) );
invoc_1.setName(ast.newSimpleName("println"));
InfixExpression infix_1 = ast.newInfixExpression();
infix_1.setOperator(InfixExpression.Operator.PLUS);
StringLiteral literal = ast.newStringLiteral();
literal.setLiteralValue("Ciao");
infix_1.setLeftOperand(literal);
literal = ast.newStringLiteral();
literal.setLiteralValue(" world");
infix_1.setRightOperand(literal);
invoc_1.arguments().add(infix_1);
ExpressionStatement expression_1 =
ast.newExpressionStatement(invoc_1);
block.statements().add(expression_1);
method_1.setBody(block);
myType.bodyDeclarations().add(method_1);
unit.types().add(myType);
String str = unit.toString();
System.out.println(str);

This is because you provide a hashtable for the options and you don't
convert existing source code. As soon as you need to get the options
from JavaCore, JavaCore needs to be initialized.

I believe that no commitment was made to support DOM AST outside Eclipse. If
this works now, this could not work in the future.

no they are right, but AFAIK serialization only works within Eclipse
with IDocument objects
