LexHTML does not define any specific state for
operators inside a VBScript section (i.e. something
like SCE_HJ_SYMBOLS and SCE_HJA_SYMBOLS).
For that purpose, I have added two more states
(SCE_HB_OPERATOR and SCE_HBA_OPERATOR).
In the attached zip, you can see the files I have
changed from release 1.70.

Maybe this (adding SCE_HB_OPERATOR and SCE_HBA_OPERATOR) can be implemented now as more styles can be used and VBScript is dead, so it's no longer need to reserve styles.

SCE_HB_OPERATOR isn't needed if client-side VBScript is removed.

Reclaiming the client-side VBScript and client-side Python style IDs needs a plan and possibly a separate new lexer.

There still appears to be some use of server-side VBScript so I don't know if that can be removed.

keep sync client/server side VBScript styles just to make the lexer simple.

Reclaiming the client-side VBScript and client-side Python style IDs needs a plan and possibly a separate new lexer.

for backward compatibility reason, they probably needs to be kept for a while.

possibly a separate new lexer.

Current HTML lexer can be separated by server side languages or template:
1. A base HTML/XML lexer that contains SGML, tag, JavaScript and CSS. i.e. current lexer without VBScript and server side or template handling.
2. ASP (JavaScript or VBScript) lexer: current lexer without PHP, Python and template, simplify SGML handling (only need to handle DOCTYPE).
3. PHP lexer, base HTML (DOCTYPE only SGML) with PHP highlighting.
4. JSP lexer, base HTML with Java (currently treated as JavaScript) highlighting.
5. lexers for each template (ASP.NET Razor C#, ASP.NET Razor VB.NET, Django, Mako, etc.)

Modularising the HTML lexer would be a worthwhile project. It needs a good configurable way of crossing from base to server and return. The state for the base lexer will be separate from the server state and both need to coordinated with attaching to lines and saving for future calls.

As well as determining styles, fold level may also be affected by both. It may be better to separate fold determination into a separate pass as is done by most languages.

Separating out the processing of client side JavaScript and CSS from base HTML would also improve maintainability and new feature implementation.

Modularising the HTML lexer

Will do some experiments later, as I already made a separated PHP lexer (with complete PHP styling, more JavaScript styles, also basic CSS highlighting) at https://github.com/zufuliu/notepad4/blob/main/scintilla/lexers/LexPHP.cxx

Rewrite the lexer or new lexers with StyleContext would improve readability and maintainability, but this may slow down loading large program generated HTML/XML file.
