@jckarter The LSP spec has modifiers (including defaultLibrary - https://t.co/1euMesQLug) which you could use to do things like this, but you'd need a theme to go with it

@Muirey03 @interface @end @implementation Yep

[David Goldman @DavidJGoldman]

TIL of the following valid ("deprecated") Objective-C:

@interface MyObject : NSObject
- readValue:(int)value, id object;
@end
@implementation MyObject
- readValue:(int)value, id object {
return [self readValue:value, object] ?: self;
}
@end

[David Goldman @DavidJGoldman]

C-style parameters is deprecated but still works although it currently confuses Xcode and crashes clangd. More importantly it leads Clang to be confused when a user accidentally puts a "," in a normal method declaration:

@interface MyObject
- (void)a:(id)a, b:(id)b;
@end

@stroughtonsmith Reminds me of the quality of service docs (see debugging tools at the bottom) https://t.co/i8V53Kjol3

[David Goldman @DavidJGoldman]

@King_Mordecai Just released an update to fix

[David Goldman @DavidJGoldman]

@ashfurrow @steipete @stroughtonsmith This is potentially unsafe e.g. if you check https://t.co/BHI79XxPIh, call a method which mutates https://t.co/BHI79XxPIh, and then access it

[David Goldman @DavidJGoldman]

@lagart30 Nope the shape change is from a theme, ColorBadges will color whatever badge shape your theme has

[David Goldman @DavidJGoldman]

@kastiglione Congrats! That's awesome

[David Goldman @DavidJGoldman]

@rockbruno_ What about debugging times?

@steipete from https://t.co/YgEKf7NdxL page 21 and 50 you might need to store %rax for var args

[David Goldman @DavidJGoldman]

@steipete Haha the debugger is definitely your friend... But it will just give you more assembly

[David Goldman @DavidJGoldman]

@mpweiher @steipete Guessing also arm64_32? Does va_arg also work for x64/i386?

[David Goldman @DavidJGoldman]

@steipete @gparker Yep you'll need to cast to the exact type or wrap it in arch-specific assembly like https://t.co/Qs4vBmLpzT

[David Goldman @DavidJGoldman]

@steipete What are you using va_list for? IIUC va_list is only for variadic arguments (not objc_msgSend which needs to cast to the proper type), does that work on arm?

[David Goldman @DavidJGoldman]

@steipete Haha looks like you're deep in the rabbit hole, great write up!
