Add support for UDL

[EuropeanDeveloper]

Notepad++ supports creation of custom syntax-highlighting files, so-called UDL (User Defined Languages). If user has such file created, this language can't be used as Language for doc when snippet starts a new document. UDL can't be also set as library language.

I have considered this, especially since Markdown is UDL. But so far I haven't been able to find a reliable way to support UDL. The main problem is to find out what definitions are installed and how to link that to a library.

As an alternative solution (or as a feature), it would be nice if NPPSnippets had a parameter that switches the visibility of snippet libraries depending on the syntax of the current file. I installed custom UDL for SPARQL files, but after creating library I can't get access to this - there aren't SPARQL in "Language for doc:" list

Could you be a bit more specific what you mean?

There is no way that I am aware of to get the UDL languages that are installed. How should I add them to the list of languages?

This is not a direct solution, but it might help.
As I understand, two things depend on the choice of syntax (including UDL): which libraries will be displayed and which syntax will be (for a new document). If you can't get a list of installed UDLs, you can improve one of the corollaries of this: allow the user to choose which libraries should be displayed
