Thanks Patrick, Greg!
Hi everyone,
I have written a GNUmakefile. The main obstacle is the pasteboard
functionality.
GNUstep implements the OpenStep/pre-10.5 OSX pasteboard (see the GNUstep
docs
<https://www.gnustep.org/resources/documentation/Developer/Gui/Reference/NSPasteboard.html>
and the Apple docs
<https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/CopyandPaste/CopyandPaste.html>);
I have no idea how it integrates with the system's clipboards. This
pasteboard contains a single item, which may have multiple representations.
Modern macOS implements the post-10.6 OSX pasteboard (see the Apple docs
<https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/PasteboardGuide106/Introduction/Introduction.html#//apple_ref/doc/uid/TP40008099>
- "Pasteboard Concepts" is the most important part), and OpenOutliner
expects this to work. This pasteboard is a list of items (for example,
if you copy a selection of a webpage which contains an image it should
put a rich text and an image onto the pasteboard), each of which may
have multiple representations. Additionally, it starts using Uniform
Type Identifiers (UTIs) in order to refer to types rather than use the
old pasteboard type strings (at least in 10.6 those old strings were
still supported but were deprecated).
It looks kind of complicated to implement the new pasteboard API, so
maybe we could try porting OpenOutliner to the old pasteboard API or
temporarily disabling all the features which need the pasteboard. Do any
of you have opinions on this?
The Uniform Type Identifiers framework, part of LaunchServices, seems to
be implemented by Boron so we could probably do that. (However, that
would make gnustep-gui depend on Boron, which may or may not be wanted.)
We might want to implement in Boron the new Uniform Type Identifiers
framework
<https://developer.apple.com/documentation/uniformtypeidentifiers?language=objc>
introduced in macOS 11 Big Sur, which is object-oriented (UTIs are of
type `UTType*` rather than `NSString*`, and it provides an Objective-C
API). Although OpenOutliner doesn't use the new UTI APIs, it would be
useful to implement in case newer apps need it, and regardless it seems
to be a cleaner API.
Thanks,
Ethan

Ethan,
Mine is gcasa. I would like to help a little if I can. Also,
expanding libs-xcode, if it needs it, to handle it.
