Yes. You seem to be bringing very valuable contributions that few developers are able to dedicate time to.

On the other hand, you also seem to be wanting to explore more depths in software development.

A parser should not scare any programmer, parser theory is well developed and well known. There are a lot of books, and online-lectures to learn about parsing, so you may learn about it and become able to modify or debug the parser or the parsed language.

Just use a search engine to find lectures about scanning (lexical analysers), parsing (syntactic analysers), and compilation in general, since it's usually in the context of compilers that parsing algorithms are studied.

Now the point here may be that for each component of your software, you may have to learn one more technique or one more theory to understand it and be able to contribute to it in a meaningful way. That's how it is: programmers keep learning all the time, we're not finished when we get our diploma, it's only the start.
