Diff the Contents of the Last Two Clipboards

Frustrated by Magento? Then you’ll love Commerce Bug, the must have debugging extension for anyone using Magento. Whether you’re just starting out or you’re a seasoned pro, Commerce Bug will save you and your team hours everyday. Grab a copy and start working with Magento instead of against it.

Updated for Magento 2! No Frills Magento Layout is the only Magento front end book you'll ever need. Get your copy today!

The title pretty much says it all. This Applescript will use BBEdit’s (or TextWrangler’s) internal diff functionality to compare the last two bits of text that have been copied to the clipboard. Tested in 10.5, not 10.6 (because I have work to do while all of you beta test Snow Leopard for me)

tell application "BBEdit"
    set text_1 to (the contents of current clipboard)
    set clip_index to the index of current clipboard
    set clip_index to clip_index - 1

    if clip_index is 0 then
        set clip_index to 1
    end if

    set text_2 to the contents of clipboard clip_index
    do shell script "rm /tmp/bbclipdiff_1.txt;touch /tmp/bbclipdiff_1.txt"
    do shell script "rm /tmp/bbclipdiff_2.txt;touch /tmp/bbclipdiff_2.txt"
    set file_1 to POSIX file "/tmp/bbclipdiff_1.txt"
    set file_2 to POSIX file "/tmp/bbclipdiff_2.txt"
    write text_1 to file_1 as text
    write text_2 to file_2 as text
    set the_result to compare file_1 against file_2
    if not the differences found of the_result then
        display dialog "Last Two Clipboards are Identical"
    end if
    return the_result
end tell

What if I Wrangle?

If you’re using the cheap-as-free TextWrangler just change the first line to read

tell application "TextWrangler"

Identical Text from Outside BBEdit

This uses BBEdit’s clipboard history feature (Edit ->> Show Clipboard). Things should work seamlessly for text copied in BBEdit itself, but if you’re copying text from another application there’s one quirk you’ll want to watch out for.

When you copy text outside of BBEdit, BBEdit will usualy shift its history accordingly. I have noticed a few instances when you’re copying identical text where BBEdit won’t shift it’s history, meaning that instead of two identical items being in the history, the second item never gets added. Normally this isn’t a problem, but since the point of the script is, in part, to quickly determine if two bits of text are the same or not, you’ll want to be aware of this quirk.
