An example of integrating a simple shell script into Vim

" When I'm editing some LaTeX, I use PDF files to handle any inserted images and
" LaTeX has some difficulty lining them up right, so I explicitly state the
" viewport. To get the bounding box from the PDF file, I have a script called
" 'getbb'. This function is /very/ specific to my needs. It pulls the filename
" from the current line, which always looks something like this:
"
" \includegraphics[scale=0.5, viewport = 40 39 703 153]{target/filename.pdf}
"
" Pulls out the filename (i.e. target/filename.pdf), runs 'getbb' on that and
" inserts the output back overtop of the "viewport = 40 39 703 153".

Add .error CSS class to all invalid form fields. Rails wraps them in div.fieldWithErrors, which still sucks in 3.0

// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
// ie === undefined
// If you're in IE (>=5) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}

# This is a code example for the Ruby HTTP library Typhoeus

# Including Typhoeus adds http methods like get, put, post, and delete.
# What's more interesting though is the stuff to build up what I call
# remote_methods.

You can’t perform that action at this time.
