oh crap, does concat create a new object, or mutate the current one? is it the same as using + or do they handle objects differently....? should I be using << here maybe? I agree with you that the verbosity of ObjC makes it harder to mentally parse fast, but I also think there is a lot of clarity to it when you read it slow. Where I see ObjC fall down is more in terms of command verbosity. For example in Ruby, File.open("readfile.rb", "r") do |infile|
while (line = infile.gets)
puts "#{line}"
end
end
...would be ~150 lines of code in ObjC (Dave DeLong: http://stackoverflow.com/a/3711079/196358). Which is not really a failing of the language, actually. It's a failing of the libraries that come with the language.Apple chose to give you a couple ways to read a file. The easy way is `stringWithContentsOfFile:encoding:error:error`, but the next level of control is way to low level. Dave DeLong's solution to reading a file line by line exposes an api that looks like this: DDFileReader * reader = [[DDFileReader alloc] initWithFilePath:pathToMyFile];
[reader enumerateLinesUsingBlock:^(NSString * line, BOOL * stop) {
NSLog(@"%@", line);
}];
Not actually much more complex or verbose than the ruby. |
