Question

I want to automatically generate an HTML document, containing docs for a Perl file. To build it I need a list functions, contained in the file. Every function has the format ‘^sub name’. Is there any function to get all function names? Or how to write it?

You can use elisp search functions:

(defun find-perl-sub ()
  (let ((subs))
    (with-current-buffer "my-perl-file.pl"
      (goto-char (point-min))
      (while (re-search-forward "^[[:blank:]]*sub[[:blank:]]+\\([a-zA-Z0-9_]+\\)" nil t)
        (push (match-string-no-properties 1) subs)))
    subs
    ))
