Syntactic Reader (Extension of Visual Studio 2013)

Question

By syntactically reading a language in a Visual Studio extension project I can already read the following:

<span class="myclass"></span>

It is relatively easy to manage read states InTag, AttributeNaming, AttributeValue (created these states). Make the correct color application by the Colorizer class and everything else.

The problem:

Visual Studio through its API sends me the code line by line waiting for me to return the tokens read. How do I read a broken line?

<span
      class="myclass"></span> <!-- Meu parser verá erros e textos apenas -->

Is there any way to group these lines? Code outlining helps in these cases? How do I use it?

In this case for example, reading a more complex language, how could I create the outlining and indetify the states? A; In namespace, B: class name declaration, C: in class, D,: method declaration, E: method name, F: method body, for example.

Answer 1

In his parser, if you are using regular expression to identify the tokens and C#, you must enable the option Multiline (m) when executing the match of tokens according to your standard.

I’ve had to create some parsers and I’ve always had a lot of basic problems, so I found the tool ANTLR.

This tool generates parsers from a grammar. Perhaps, in your case, it’s easier to write the grammar than you need to identify and have the ANTLR manage the parser for you.

The ASP.NET MVC Bundle uses ANTLR to interpret javascript and css and minify them. So this is a reliable tool and, let’s say, "well-tested".
