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.

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

Looks as if emacs has internal functionality to determine start and end of elisp expressions, which rainbow-delimiters relies of.

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.
