In the screenshot, you can see that the selected IndexerExpression " args" has the child identifier " args" in the Target role, and the child " 0" in the Argument role. The titles describing the nodes in the demo's tree view follow the pattern "node.Role: node.GetType().Name". A child node's role describes the relation between the parent node and the child - it explains where in the parent the node appears. (the term "AST" stands for Abstract Syntax Tree)Įvery node has a list of children, and each child has a role. The base class of the syntax tree is the AstNode – every item in the demo application's tree view is one AstNode. The syntax tree can be visualized using the NRefactory.Demo application: Syntax errors detected while parsing can be retrieved using the parser.Errors collection. SyntaxTree syntaxTree = parser.Parse(programCode) To understand the different stages, consider this simple piece of code:Ĭollapse | Copy Code CSharpParser parser = new CSharpParser() NRefactory offers APIs for accessing syntax trees, semantic information, and the type system. NRefactory is also used in the ILSpy decompiler, in Unity's IL-to-Flash converter, and as a front-end in the C#-to-JavaScript compiler Saltarelle. NRefactory 5.0 has recently shipped with MonoDevelop 3.0. This allows us to share them between SharpDevelop and MonoDevelop. The goals of the rewrite were to have a more accurate syntax tree (including exact token positions), and to integrate the IDE-specific semantic analysis features and refactorings into the NRefactory library.
This article describes NRefactory 5, a complete rewrite that was started in July 2010.
It is quite similar to Microsoft's Roslyn project except that it is not a full compiler – NRefactory only analyzes C# code, it does not generate IL code.
It allows applications to easily analyze both syntax and semantics of C# programs. NRefactory is the C# analysis library used in the SharpDevelop and MonoDevelop IDEs. Get the latest NRefactory version on NuGet: ICSharpCode.NRefactory.
