Emacs: press F5 to reload Firefox browser

this is great for web developers. Press a key in Emacs to save your work, then reload a page in a real browser!  If you're doing debugging with Python logging, this is all you need to do for rapid development.



(require 'net-utils)

(defun save-buffers-reload-browser ()
  (interactive)
  (save-some-buffers t)
  (run-network-program "Firefox" "localhost" 32000 "reload"))

(global-set-key (kbd "") 'save-buffers-reload-browser)

Web Editing with Emacs tricks

this is awesome and very useful:

C-c C-f

Skip across a balanced tag group (which extends from an opening tag through its corresponding closing tag) (sgml-skip-tag-forward).   (Backward = C-c C-b)

C-c C-d

Delete the tag at or after point, and delete the matching tag too (sgml-delete-tag). If the tag at or after point is an opening tag, delete the closing tag too; if it is a closing tag, delete the opening tag too.       

C-c /

Insert a close tag for the innermost unterminated tag (sgml-close-tag). If called within a tag or a comment, close it instead of inserting a close tag.

all test test-fast:
 ./$(RECENT_PY)

after installing Flymake, create this Makefile:

all:
