Elisp: Regex Patterns and Syntax Table
here's a demo, that some regex depend on syntax table.
;; here's a demo, that some elisp regex pattern depend on elisp syntax table. ;; save this file as test.el, and open it. ;; M-x emacs-lisp-mode ;; put cursor right after the paren, and M-x eval-last-sexp (re-search-forward "[[:space:]]") ;; it'll move cursor to a space ;; now, set space to have word syntax. Eval this (modify-syntax-entry 32 "w" emacs-lisp-mode-syntax-table) ;; try the search above again. Now it won't find any
After the above, you'll need to restart emacs. Because, now cursor moving commands will consider space as part of word.
