Hello,
Someone was asking me about whether Emacs.app supports the "- GSFilePath"
option which GWorkspace uses to tell applications to open files. I thought
that there were already two ways to do this in OpenStep / Cocoa: "-NSOpen"
option, and NSApplication- application:openFIle: method via DO or
notifications. Is this correct or is the GNUstep-specific -GSFilePath
really needed?
thanks,
Adrian
If the application is running GWorkspace uses -application:openFIle:, if not it
launches it with -GSFilePath and the path of the file to open as arguments.
In NSWorkspace.m I read:
* <p>If the Info-gnustep.plist of an application says that it
* can open files with a particular extension, then when NSWorkspace
* is asked to open such a file it will attempt to send an
* -application:openFile: message to the application (which must be
* handled by the applications delegate). If the application is not
* running, NSWorkspace will instead attempt to launch the application
* passing the filename to open after a '-GSFilePath' flag
* in the command line arguments. For a GNUstep application, the
* application will recognize this and invoke the -application:openFile:
* method passing it the file name.
* </p>
and, in NSApplication.m, we find:
/*
* Now check to see if we were launched with arguments asking to
* open a file. We permit some variations on the default name.
*/
if ((filePath = [defs stringForKey: @"GSFilePath"]) != nil
|| (filePath = [defs stringForKey: @"NSOpen"]) != nil)
{
[_listener application: self openFile: filePath];
}
...
That is, NSApplication treats "GSFilePath" and "NSOpen" as the same thing and,
if Emacs.app implements -application:openFIle: in its delegate, this is the method that will be
called.
