Paste or type in a piece of code in the CODE text area below then press the "Parse to AST" button. The system will invoke the Temporal Wave C# parser and report the timings and so on at the bottom of the page. If the parser is successful, the system will produce a graphical representation of the Abstract Syntax Tree produced by the parser.

Please note that the process of producing a dot (see the free Graphviz toolset) specification and generating a resulting PNG graphic is quite expensive. This system is a low powered web server and it can take a few seconds to produce the image for a large input. Note however that the process of lexing, parsing and walking the AST is very fast, even on this small server. You may find that you need to scroll quite some way to the bottom of this page to see parser error output etc.
