Build?

[jamesstout]

How do yuo build this? I'm getting missing deps for the linked binaries/frameworks, pngquant, pngnq, posterizer and sparkle. And probably liblibpng. Could they be added as git sub-modules?

Just out of interest, why did you decide to use PyObjC?

thanks

Sorry about that. You'll find libpng and Sparkle project in ImageOptim. The
rest create as cli tool and just add all C files.

regards, Kornel

Have you managed to build it?

[jamesstout]

Not yet - not had time.

Somehow - I got it building...

[kornelski]

Great. I suppose you had to change project file or some other bits? Is that something you could contribute to the project?

What steps need to be documented?

Just an excuse to learn Python :)

It thought it'd be easier to work in higher-level language than ObjC (only 1.0, no GC when I started), but PyObjC wasn't as fun as I hoped:

• lousy runtime error reporting with no Xcode integration.
• no compile-time error checking, and regular python linters I've tried didn't like objc imports.
• there was a time when users were installing custom Python version that wasn't PyObjC-compatible, so I had crash reports that I couldn't do anything about.
• type conversions and memory management require knowledge of both pythonisms and Cocoa patterns, to the point I couldn't get layer-backed patterns to work in PyObjC without crashes (I'm still not sure if that's bug/missing bridge in PyObjC or I missed something. Same code in plain ObjC works fine.)
• in addition to forgetting explicit self in method declarations I keep forgetting trailing underscore in method names that PyObjC requires. Python's syntax can't handle Cocoa's method names well.

In the meantime ObjC went a long way with GC, ARC, properties, iterators, blocks, etc. so I probably won't write another PyObjC app.

It was a lot of trial and error. Not sure I can remember the steps.

I'll start afresh and document....

I made some (private) changes to sabnzb and CouchPotato to learn Python :-)
