Highlighting EBNF ISO/IEC 14977:1996(E) syntax

Unread post by Andrey Bushman »

It would be great if Help and Manual can highlight standardized variant of EBNF syntax according ISO/IEC 14977:1996(E). Is it possible? At current time any EBNF syntax is absent in the list of languages on the Customize Syntax Highlighters window. As I understand by documentation - I can edit highlighting only of already existing languages, but I can't add new ones. Am I right?

Thank you.

Hi Andrey,

You can create customized highlighters to a certain extent. You will have to see whether the options are enough for what you need here, however. See this chapter in the help for details (user-defined highlighters):

I already read it. Maybe I incorrect unerstand you... To change highlighting is not a problem... But highlighting shall be executed according to the necessary syntax. For example, how the program of syntax highlighting learns, what in standard EBNF the comment is the text framed with characters (* and *)? How highlighting will be able to define, where in my code is the terminal character or where is the non-terminal character? Problem not with highlighting but the problem with parsing. Look the attached screen. The list has not EBNF item.

Hi Andrey,

That's what I meant when I wrote that it may not be flexible enough to cover your needs. I'm afraid there are no additional options at the moment.
