Ah, sorry, here’s the latest version of the LexerInputCharStream file:

(This one avoids the Google Guava dependency.)

I have used both JavaCC and ANTLR in the past, and I highly recommend using 
ANTLR for new projects.

You can use the following adapter class to hook ANTLR’s 
org.antlr.v4.runtime.CharStream interface up to NetBeans’ 
org.netbeans.spi.lexer.LexerInput interface:

Hello,

latest tutorial I found is at
https://platform.netbeans.org/tutorials/nbm-javacc-lexer.html - but
JavaCC seems to be no longer actively supported. I'm also not sure, if
this is using latest language infrastructure: Though it states "Requires
NetBeans 8.1", it uses e.d. "org.netbeans.spi.lexer.LanguageHierarchy".
IIRC this is older than GSF/CSL API, which is used e.g. for the
(netbeans-internal) YAML module.

Which API should I use?

Kind regards
Peter
