Re: NSAppleScript and System Events

Programmatically, not AppleScript, and that of course is still only valid for running processes.

For the running Finder, ProcessManager process types something like...

#include <Processes.h>

#include <Files.h>

#include <sys/types.h>

/**

    Compile with...

   

gcc -I/System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Headers -I/System/Library/Frameworks/ApplicationServices.framework/Frameworks/HIServices.framework/Headers -framework CoreServices -framework ApplicationServices -o mps mps.c

*/

int main(void) {

    mps();

}

int mps() {

    ProcessSerialNumber psn;

    ProcessInfoRec        info;

    Str255                 name;

    FSSpec                 appspec;

    short                 err;

    pid_t                pid = 0;

   

    info.processName = name;

    info.processInfoLength = sizeof(ProcessInfoRec);

    info.processAppSpec = &appspec;

    err = noErr;

    psn.highLongOfPSN = 0; psn.lowLongOfPSN = kNoProcess;

    for (;;) {

        err = GetNextProcess(&psn);

        if (err == procNotFound) break;

        if (err != 0)

            printf("mps: error getting process. err: %i\n",err);

        else {

            err = GetProcessInformation(&psn,&info);

            if (err == noErr) {

                printf("Name: %s\n",p2cstr(info.processName));

            }

            else printf("mps: error getting process info. err - %i. continuing...\n",err);

        }

    }

}

should work. Although again thats not AppleScript.

Where I've had problems since I think 10.2 is finding non-running applications by creator OSType. I think I went with a dummied up supported file extension which I think worked as a fallback even if the application wasn't running. Although I haven't verified real recently that it is actually a valid fallback. This is code I pretty much just use myself as far as I know, so I've gotten into the habit of always just making sure the application I'm looking for is already running which will work including by creator type I think. 

It would be nice if I could get it to reliably launch when needed.
