@PeterJones I have tried the HiddenLexer plugin and I am impressed. I tried to add another lexer though failing to style for some unknown reason. When the plugin progresses from the Alpha state then may try again. The “Hello Notepad++” works too though Notepad++ does not seem to respond back with a “Hello Plugin” :). The plugin has some good potential to access the other 1/3 of lexers that Lexilla provides. The plugin is looking good so far with the setup of AsciiDoc. I checked the history and the AsciiDoc lexer was added and released in December of 2021. This is probably the first time that I have seen AsciiDoc working as I have no previous experience with using the format.
