Re: Selective Font Lock Case Sensitivity

[Jacob Gerlach <jacobgerlach@gmail.com>]

I'm having trouble implementing this, I think because of some more basic lisp understanding deficiency. 

I'm constructing entries for my-font-lock-keywords by using mapc to work from a master list.

The function called by mapc adds a backquoted list to my keyword list. Before trying to adjust case sensitivity, it looked like:

(defun add-to-my-keyword-list (input)
   (add-to-list 'my-font-lock-keywords
	       `( 
		,(;;non-buggy-code here for anchor)
                ,(regexp-opt (cadr input))
                (my-pre-form)
                nil
                (0 font-lock-keyword-face))))

My trouble is getting (regexp-opt (cadr input)) to properly expand to an argument for re-search-forward.

The closest I've been able to come is to use

(lambda (limit)
  (let ((case-fold-search t))
    `(re-search-forward ,(regexp-opt ,@(cadr input)) limit t)))

In this case, (cadr input) is evaluated, but (regexp-opt is not. The constructed list reads
...
(\` (re-search-forward (\,@ (regexp-opt
...

Is this an easy fix?
