I still remember my horror when I saw the pain of something as simple as string concatenation in Objective-C. The community literally has to write special micros to make joining a string palatable [1]. I salute the brave souls who made OSX/iOS apps before Swift. NSString *myString = @"Hello"; NSString *second = [myString stringByAppendingString:@" World"]; [1]: https://stackoverflow.com/questions/510269/shortcuts-in-…

I never felt like this was too terrible...

  NSString* result = [NSString stringWithFormat:@"%@ %@", @"Hello", @"World"];

NSString *foo = [@"foo" stringByAppendingString:@"bar"]; It's not that bad.

I must be missing something here. "foo" + "bar"

It's more like compile-time concatening of literals like in C when doing

  const char *s = "foo" "bar";

Yep. Still working on it. Suggestions?

Definitively not that one!

This is hugely interesting!

So it creates a runtime directly on the silicon? no VM no GC?

How does free memory? Automatic reference counting?

to me thats whats cool about obj-c, not the syntax or whatever, but the runtime

that you can construct classes and methods at runtime just like a "vm" but much simpler and lightweight... its amazing to me that apple never made a construct-the-app-while-its-running type of rapid development tool... the pieces were all there afaik

If you can build Objective-S in a language then isn't the language that contains the set of Objective-S and other languages in theory more general purpose? I'm not sure I get the definition.

I guess it's the same question as whether the ability to implement an Erlang VM in C makes C a functional and/or concurrency-oriented language.

C is a functional language[1]. That’s one of the finer examples of Haha, Only Serious I’ve seen for programming.

My two pence: It’s not a very sexy name for a language compared to the competition.

General Purpose Language, since it is the world’s first general purpose language.

It's not obvious how Objective-S handles unreliable resources.

I ask because every remote resource is unreliable on several levels, and it's often both important and impossible to figure out which level is misbehaving. (Is AWS down, Comcast, my router? Or did I fat-finger some part of the URI?)

While this syntax is indeed popular in several languages it's deeply weird, it's like how English uses apostrophe S to do two very different things at the end of words.

The Add operation has a whole bunch of properties and this not only isn't most of them, it's arguably not any of them, the main argument for + as a string concatenate operator is "Well, people seem to like it". Which, I guess I/O streams doesn't even have that going for it, but it's a pretty terrible rationale.

Look, just grow string interpolate and write f"{foo}{bar}" or whatever as much as you like don't abuse unrelated operators.

Arguably, it should be First General Purpose Language then. Might also help avoiding confusion if the implementation isn’t GPL.
