I'm currently writing an IntelliJ plugin. This plugin should handle HTML, Java (sometimes also JavaScript) and rythm (a template engine) I followed the plugin documentation of JetBrains.
My lexer (I use JFlex) matches everything and recognizes the matched code as HTML.
For the rythm code parts I have regular expressions in my lexer.
I also want to implement some Java Language features like the completion of packages and classes.
Also I don't know if my approach is correct. Because my lexer splits HTML at some points:
@, (, ), {, }
The regex to match the complete code and recognize it as HTML is:
TEXT = [^@*(){}]+
This regex causes the problem that my HTML Code is splitted at points where the code starts with @, (, ), {, and } If I don't except these characters my plugin doesn't reconize my other regular expressions and my brace matcher would not work anymore because it would match everything.
Is there a better way to support multiple languages and how do I implement Java language features in my plugin?
