3. [NSWorkspace -launchApplication:] does not work correctly. The

That might be a bug as you suggest... how does OpenStep/MacOS-X do
it? I thought it counted 'launch' as meaning that that it had
started the new task rather than as meaning that the application had
completed all its startup. It's very simple to change this of
course, but we need to be sure what the correct behavior is.
Further investigation seems to be quite clear that the current
implementation is correct (ie the way MacOS-X does it).
Yes, if you consider that the way MacOSX does it is the correct way.
Other thing is that how would you expect it to behave.
It behaves the way MacOS-X behaves.
It behaves the way I expected it to behave.
I do not think is is reasonable to introduce incompatibilities unless
MacOS-X is *OBVIOUSLY* wrong. In other words, not only must your
opinion of how it should work be different from the MacOS-X version,
but your opinion should be overwhelmingly agreed with by other people.
Perhaps it might be worth making the GSContactApplication() function
from GSServicesManager.m public, since it
wraps the code for contacting an application already?
This is something I wanted and was asking for. I knew that there are
some methods in -gui for doing the sutff and I just wanted them to be
public. Thereis also a method -_connectApplication: in NSWorkspace.m,
but it seems to be different from GSConnectApplication.
GSConnectApplication is good method, but it requires some NSPort and a
NSDate to be passed. Would it be possible to create a simple wrapper
fot that method which takes just one argument? like public gnustep
extension method in NSWorkspace -listenerForApplication:(NSString
*)name ?
Sure it's possible, but my vote is against doing this.
I don't believe that this would be a good extension...
Keeping APIs as small and simple as possible should be a major aim for
GNUstep.
Additional APIs should add really useful functionality, either useful
for *lots* of people, or providing important features that can't
reasonably be handled another way. This doesn't qualify.
The problem is, people work on their own code, and see a feature they
want for what they happen to be doing now. Psychologically, it's hard
to step back from the current work and look at whether the feature will
be used. Over the past few years I have removed a *lot* of
non-standard stuff from the base library (some things that I added
myself in earlier days) as it became clear that nobody was using it and
it was just confusing newbies.
The code to handle launching and connecting to an application is pretty
simple really, and very few applications ever need to use it ... so
adding a public convenience method to do it is IMO a bad thing.
Also, I think that most inter-application communications can (and
probably should) be done using services rather than direct messaging,
so that services provided by applications are advertised to other
applications in a uniform manner ... direct messaging is a pretty
special case for closely cooperating apps which can't use the standard
services mechanism for some reason.
