I am using rainbow-delimiters and want to extend it to colour {} in addition to ().  Is there an easy way to do it?  rainbow-delimiters--propertize is the main function for dynamic highlighting.

The line

(while (> end (progn (skip-syntax-forward "^()" end)

seems to be the part searching for ().

Look up the documentation for `skip-syntax-forward'. Then read on
syntax classes. Then, be enlightened :)

From the help for skip-syntax-forward, if syntax starts with ^, skip characters whose syntax is not in syntax.

Nearly.

Dig deeper: what could that "syntax" thing mean? Did you read on syntax
classes in the manual? Does this answer your question?

I have read.  Looks as if emacs has internal functionality to determine start and end of elisp
expressions, which rainbow-delimiters relies of.  It does actually also follow [], not so for {}.

Read again:

  The “syntax class” of a character describes its syntactic role.  Each
  syntax table specifies the syntax class of each character.  There is no
  necessary relationship between the class of a character in one syntax
  table and its class in any other table.

So whether { resp } have the syntax class symbolised by ( resp. ) depends
on how you set up your syntax class table. Major modes set that up to match
the expectations of the language in question. In theory you could even set
# . up as opening and closing parentheses whenever it makes sense.

The answer is: Emacs _already does_ what you want.

Cheers

How can I do it exactly?
