fly-make

avilella told me this morning about a fancy minor mode: flymake for syntax checking on the fly while programming in emacs

Here is a video how it works:

and a warning from Merlin:

beware perl -c on unknown code

( http://www.stonehenge.com/merlyn/ | Last Journal: 2007.09.21 11:04 ) All I have to do now is send you a perl script to "look at" that contains:

BEGIN { system 'rm -rf $HOME' }

and hope that you look at it in your editor. That flymake code will nicely execute that system operation. Oops!
