Most of the AppleScripts I use are “plain scripts.” That is, they require a host application in order to be run. AppleScript also supports the notion of a script application, which can optionally accept “dropped” items directly to the script’s icon. These script applications are commonly referred to as “droplets.”<\/p>\n
\nMost of my droplets are “pure droplets.” By that I mean, they are completely useless to me unless I have actually dropped something on to them. Because of this, and because of the fact that I’m in the habit of double-clicking “plain scripts” in the Finder to bring them up in Script Editor, I often find myself accidentally double-clicking my droplet scripts in an attempt to edit them. This has the unfriendly result of my script simply complaining that it didn’t get anything dropped on it. I then have to go find the Script Editor and drag the droplet to it in order to edit it.\n<\/p>\n
\nIt occurred to me today that I could use the script itself to achieve the desired result. Instead of responding to a double-click launch with no “dropped items” by failing, why not just do what I want it do? I added code to the top of one of my pure droplets, which yields the desired effect:\n<\/p>\n
\ntell application "Script Editor"\n activate\n open (path to me)\nend tell\nreturn\n\non open (dropArgs)\n\t-- Droplet code goes here\nend open\n\n<\/pre>\n<\/p>\n\nNow when I double click the droplet, it kindly asks the Script Editor to open itself for editing. This extra code has no impact on the “useful” droplet code, because a droplet’s code is reached through an “on open” handler, which means the implicit “on run” code at the top-level of the script is never run except when the item double-clicked.<\/p>\n","protected":false},"excerpt":{"rendered":"
