I think we have similar problem, then. 2. and 3. I could do easily as that is basic coding or Lua knowledge.You need to attach an event handler to editor:Connect(wxstc.wxEVT_STC_UPDATEUI, function(event) end) or editor:Connect(wxstc.wxEVT_STC_STYLENEEDED, function(event) end) events; at that time GetEndStyled() should return the correct value needed for that function to work. Scintilla documentation has bit more information, although the styling process is missing some details: http://www.scintilla.org/ScintillaDoc.html#SCN_STYLENEEDED I'd try to do this in three steps: 1. Take unmodified MarkupStyle and make it work for the text in Reference panel. It will require several things: (1) attaching an event handler (as described above); (2) calling MarkupStyle with the right parameters, and (3) applying styles to your editor (see StylesApplyToEditor). These styles will only be applied to markup in comments. 2. Provide "fake" editor.spec.iscomment to make it work with markup not in comments. You'd need to set editor.spec.iscomment[style] to true for all the styles you want to style it on; the simplest way is to set it to "true" for values 0..30 (at least for now). 3. Update markup symbols to make it work for your markup (similar to what you've done). Since UPDATEUI and STYLENEEDED can't be triggered directly, which makes it a bit difficult to test, you can use editor:Colorise(startpos, endpos) method to force restyling of a fragment of the document. Please keep me updated as I'm interested in getting this to work, but don't have time to try myself at the moment. Thank you.
But 1. and all those events and Scintilla functions require in-depth Scintilla and wxWidgets knowledge, two things I do not have. Honestly, I would not know where to start. On what editor to call connect? What should be the content of the attached function? How do Scintilla events even work? What does GetEndStyled() even do? What are "right" parameters for MarkupStyled? etc... I am used to working with interface libraries like Qt, OpenFL/Flash, haxeui, Mono, librocket, all of which allow you to style via HTML/CSS. This kind of effort just to have something written bold honestly scares me away :)
While that sounds like an interesting thing to to toy around with, unfortunately I do not have the time to learn Scintilla/wxWidgets right now, especially for such a "small" gain. Having that permanent documentation window with full content control is already a HUGE help.
Having it styled would "only" be the icing on the cake ;)
