Set selection inside a function or class

Hello,

The best way to locate types/members is if you use the resolver or iterate an IAssembly to get the ITypeDefinition or ITypeMemberDefinition you want.  For instance, IProjectAssembly has a SourceFiles collection.  Each ISourceFile has a TypeDefinitions collection.  ITypeDefinition has a SourceFileLocations collection where each ISourceFileLocation has a NavigationOffset (usually points to the name of the type) and the TextRange (full text range).  ITypeDefinition also has a Members collection that lets you get to nested types or ITypeMemberDefinitions, which also have SourceFileLocations.

Once you know an offset for the type or member, you'd get the document's ParseData and the DotNetParseData in it.  Then call parseData.Ast.FindDescendantNode(offset) to locate the AST node for the target definition.  Note that you may need to move up an AST node level if it ends up on like the SimpleName for the the type/member name.

Then go into the Body AST node off the type/member (e.g., ClassDeclaration.Body) and look at the first child AST node if there is one.  The start offset of that AST node is where you'd want to move your cursor.

Thanks, indeed this works. However, when body is empty, there will be no childs. But I still need to set the cursor in between the brackets and after the indent.

public int Add(int x, int y)
{
     (selection should be here)
}

Hello,

If there are no child AST nodes, then you'd need to get a snapshot reader and start at the body's start offset.  Do some text scanning at that point to skip over any first "{" (if in C#) and find the appropriate offset by examining what whitespace comes after.
