Feature request: export regular expressions

[Reissner]

I use this piece of software mostly in the context of latex writing a build tool in latex.
But I also want to integrate with latexmk which is in perl and also with splitindex which has an implementation in Lua.
So I am interested, to read in patterns in java, but export the according in other languages,
most notably in perl, python and lua.
It would be a great help to just create a pattern in java and then export that pattern as a pattern string
as required in the various languages.
If impossible to export something equivalent, an exception shall be thrown.

This is a feature that has nothing to do with this library, but would be an additional tool, just for your specific purpose. I give programming lessons. If you want to tackle that project in a paid lesson, write an email to me ***@***.***

Hm, I feel since this library has all internal structures required,
it shall be easy to convert a pattern back to string.
This is already implemented by toString(), but of course only returns java representation.
If toString() is endowed with a parameter,
one can quite easily return pattern in any language.
Of course, sometimes not feasable throwning an exception.

On the other hand, a separate lib.. difficult,
without exposing the internal structure of a pattern.

Probably you know this: https://www.regular-expressions.info/

Another thought: Frequently, there are projects with inhomogeneous technologies and also languages.
Your library could be a means to bridge the technology gap in regex related aspects.
