Extending Your Editor: Edit Extender DA

If you’ve programmed for awhile, you’re bound to to encounter one or two text editors you really feel comfortable with. Be it EMACS on a mainframe or QUED on a Mac, a good editor has a way of growing on you. You savor the power, the flexibility, and all of those little features that really make it stand out. Then comes the day, for some reason or another, when you’re forced to use another editor. You click on the menu bar and your favorite feature isn’t there. A keyboard command just puts a non-ASCII character on the screen. You grit your teeth and code away, wishing your preferred editor was around.

I was rudely awakened to this predicament when I started to use MPW and Lightspeed C. QUED had long been my editor of choice on the Mac, and I suddenly found a few of my favorite features weren’t around anymore. Granted, I could continue to use QUED or even be more ambitious and write my own editor with a little help from Symantec’s CAPPS, but I really like the notion of an integrated programming environment. To me, it’s a hassle to transfer from your editor into your main development environment all of the time.

Ah, but that’s the joy of being a programmer. You’re not forever an end user, hoping and praying the software gods will deliver you from want. You can rise above the masses with an idea and a compiler. The problem of creating an extendible editor can easily be solved by simply writing a desk accessory.

The theory goes like this. You have a chunk of text you want to manipulate within your editor. You just select the text, copy it into the clipboard, capitalize/count/do whatever to it, and then paste the altered text back in, replacing the previous selection. You let the text editor do all of the work, while you sit on top, adding your own features through the DA. No sweat, DA spell checkers like Thunder! do it all the time. Just combine the concepts of the sample “Windows” desk accessory included with Lightspeed C with some clipboard related code, and viola, a few quick hours of programming gives you the features of your favorite editor in a least favored one. Specifically, in the following example, capitalization, changing case, word counting, time and date insertion, and saving a selected region to a text file.

The Clipboard, Fake Keydowns, and Timing

The obvious storage location for storing text to be manipulated is the clipboard, alias the desk scrap. Once the text is there, it can be twiddled with to your heart’s content. So, the first thing to do is get the selected text into it. Now being somewhat lazy in not wanting to menu select Copy or Paste or type their keyboard equivalents all of the time, I decided there must be a better way, more in tune with the Mac interface. Something along the lines of having the text selected, pulling down the DA’s menu, and having the command executed.

The solution is to post a Command “C” (the non-case sensitive, universal Mac key command for “Copy”), and fake the editor into thinking the user had just done a copy into the clipboard. It’s a pretty easy task to post a keydown event with the PostEvent trap, but unfortunately you don’t have any control over the modifiers. If you pass in an ASCII “c” eventCode, and a “keyDwnEvt” eventMsg, all you’ll get is a lower case “c” on the screen. There are no provisions for specifying that the command/option/shift/caps lock keys may also be pressed. There are two choices in dealing with this problem: (1) Post some mousedown events with the locations of the “Edit” menu and “Copy” position, essentially faking a menu selection with the mouse. A risky proposition since you rely on the editor following Apple’s interface guidelines of where things should be. (2) Fake the Mac into thinking a command modifier key has been pressed.

The quick and dirty way is to pick door number 2 and modify the event queue. Using TMON, the location of the key modifiers are readily apparent. (Snoop around at $174 and start pressing keys.) Just change a byte here and there, and presto, the keydown “c” event is turned into a Command “C” copy event. The same technique can be used when replacing text, by posting a Command “V” for paste. You just select a menu item, Edit Extender posts a Command “C,” and the text is sitting in the clipboard ready for manipulation.

At this point, things begin to get a bit murky. If you were to implement the above method in a desk accessory, you’d see the menu bar flash, signalling the Command “C” had been posted, but no text would be copied into the clipboard. What’s going on here? The solution is a matter of timing. The DA has to tell the operating system that it’s finished, have the application take control again to do the copy, and then signal it wants to take control again. This can be accomplished with the desk accessory’s csCode parameter. Just pass in an integer in the accRun message and branch as required. With the timing problem solved, Edit Extender worked great. I now had some of my favorite features up and running. Then I was in for a rude surprise. Out of curiosity, I decided to try running it with MacWrite and Microsoft Word. It didn’t work at all. Something strange was going on. The DA worked fine with MPW, Lightspeed C, miniEdit, and QUED, but fell flat on its face when it came to “real” word processors.

Private Scraps

Despite having the same purpose, when it comes to using the clipboard and copying and pasting, text editors and word processors are two different critters. Most word processors that do any kind of text formatting (bolding, underlining, italicizing, etc.) keep the text they are dealing with in what “Inside Macintosh” refers to as a “private scrap.” This is simply a private clipboard where the application stores text and formatting information for internal use. For the sake of speed and efficiency, when the user selects some text and copies or cuts it, more than likely it’s going to end up someplace other than the desk scrap. On the other hand, virtually every text editor that deals strictly with text, will use the desk scrap for storage. This is why you can access copied text through the clipboard from the Lightspeed or MPW editor, but not from MacWrite or Word.

The Scrap Manager section of “Inside Macintosh” enlightens you to the fact that it is good and required programming etiquette for an application to transfer its private scrap to the common access desk scrap whenever a user quits the program or when a desk accessory becomes active. In doing so, formatted data should be converted into a form readable by either another application or the desk accessory. That means text turns it into a type ‘TEXT’ resource (simply a series of ASCII characters), graphics become a ‘PICT’ type, and optionally, any formatted information can be kept with its own unique resource type.

I fought off the temptation to cop-out and use Edit Extender exclusively with text editors. After all, it might be nice to have it work with word processors or even desktop publishing applications. So, what determines if a desk accessory is activated or not? Simple, if a window that is owned by the DA is brought to the front and becomes the active window, the desk accessory becomes activated. If another non-DA window comes to the front, the DA is deactivated. Not wanting to splash an ugly window on the screen, I decided to make my window appear offscreen at the upper left corner. Now when Edit Extender got a command, it brought the offscreen window to the front, the application received a message that a DA had become active and converted its private scrap into the desk scrap. The DA goes away, and presto, text now awaits us in the desk scrap.

With the window code working, Edit Extender was in business with MacWrite. With the exception of one small detail. If you had some formatted text (say italicized Geneva 10) selected, and used Edit Extender to capitalize it, when it was pasted back in, it came back as Geneva 12 plain. Clearly a case of WYDWISYG (What you don’t want is what you get!). Remember that when the private scrap is converted, it can also place formatted data in the desk scrap. That’s exactly what MacWrite is doing. In addition to the ‘TEXT’ resource, MacWrite is placing a ‘MWRT’ resource in the desk scrap that contains the text with formatting information. When MacWrite pastes back in, it will first look in the scrap for a ‘MWRT’ resource, and if it’s there, paste it in with all formatting intact. If there’s none to be found, ‘TEXT’ will be pasted in at Geneva 12. The solution to this problem is to get the clipboard format of the ‘MWRT’ text. In this case, look at Tech Note #13, MacWrite Clipboard Format. Although this version of Edit Extender doesn’t support formatted text, to do so would be fairly trivial. After you’ve posted the copy event, just scan the desk scrap for a resource with the type ‘MWRT.’ If you find it, then based on the data structure, go in and find the text and manipulate it.

Microsoft machinations

Hmmm. Now it was working with MacWrite, but wasn’t with Word. Ack! The simple DA was turning into a frustrating programming exercise. Oh well, when in doubt, get your debugger out. TMON revealed an interesting characteristic in Word. In addition to requiring the desk accessory to be activated, it also needed a Copy (Command “C”) or Paste (Command “V”) event before it would convert its private scrap to the desk scrap. Picky, picky, picky. After sliding in the appropriate code, and seeing no problems with using it for other applications, Edit Extender now seemed to work just fine. (Be advised though, that unlike MacWrite, the current version 3.0_whatever doesn’t place any formatted text into the clipboard. Rumor has it that future versions will place RTF into the desk scrap along with unformatted text.)

MultiFinder considerations

With any desk accessory that interacts directly with an application, you need to keep in mind MultiFinder and its buddy the DA Handler. Since Mr. DA Handler treats a desk accessory like an individual program, I was expecting some major complications. I know, Apple says to write small applications instead of DAs, but I still like interactive desk accessories. Fortunately in their infinite wisdom, the creators of MultiFinder left a nice loophole for DAs like Edit Extender. The solution is to hold down the Option key when initially selecting and launching the desk accessory. That means click on the apple menu, hold down the Option key, and select the DA. (If you hold down the option key before you select the apple menu, MultiFinder won’t display any DAs.) This little known technique bypasses the DA Handler, and installs Edit Extender (or any other DA for that matter) directly into the application’s heap.

(MultiFinder Caveats: In using the Option key method be aware of two things. (1) If you get out of memory errors, quit the program and increase the application’s memory size. (2) This technique allows you to run the desk accessory within only one application at a time. If you wanted to run Edit Extender in (i.e) MacWrite and PageMaker at the same time, just create a duplicate of Edit Extender and use ResEdit to give it a different DRVR resource name. Font DA/Mover will give it a unique resource I.D. when you install it, and you’ll be set.)

Conclusion

Edit Extender was built so I could have some features available no matter which Mac editor I had to use. It demonstrates some neat tricks like posting copy and paste events and converting text for DA use. But for the most part, it’s pretty much of a base to work off of. I included my pet features, and with a bit of coding, so can you. Some other options that could easily be incorporated include: sorting, search and replace, paragraph numbering, selected text printing, or indexing. Happy editor constructing!
