py

oh. my. god. i just learned about pymacs, which allows two-way communication between Emacs Lisp and Python. I'm moving from Ruby to Python, and this sound spectacular.

ani-fcsh.el fix

Here's a little fix for the awesome ani-fcsh.el mode for Emacs that let's you efficiently compile Flex in Emacs. For me on Emacs 23, ani-fcsh.el wouldn't restore compile correctly, this fixes it.

(defun fcsh-restore-compile ()
"See `fcsh-compile', `*fcsh-compile-active*' for more info."
(interactive)
(if *fcsh-compile-active*
(progn
(setq *fcsh-compile-active* nil)
(fset 'compilation-start (symbol-function '*fcsh-compile-old-compilation-start*))
)
))

eval

C-x C-e runs the command eval-last-sexp


I can never remember the keystroke for this, I always look for something starting with C-c.

flex compile

Emacs and the Flex Compiler Shell

Nice.

To get it to run, first go:

fcsh-compile

Then just compile normally with:

M-x compile

or

M-x recompile

emacs + flex builder = ftw

Holy, I am running Windows 7 host with Ubuntu guest inside of VirtualBox. Works amazing. Anyways, got Flex Builder running on Windows, it's really sweet, much better than the Linux Alpha version. So, I mounted my Windows drive to be accessible by my user id in /etc/fstab:

sness /winsness vboxsf uid=500,gid=500,convertcp=iso8859-1 0 0

Then you just have to edit files in Emacs on Ubuntu and the changes show up automagically in Eclipse. In Emacs on Ubuntu you will want to revist the files you change on Eclipse with:

C-x C-v - runs the command find-alternate-file

But Emacs will warn you about this if you try editting them. Eclipse seems to figure out when files have changed and automatically rebuilds them. Nice, but spooky!
