if you have to do it, you can try and make refinements work for you:

http://yehudakatz.com/2010/11/30/ruby-2-0-refinements-in-practice/

but just a fair warning, they're basically useless because any class worth monkey patching is probably being constructed through some factory module or something, and the factory wont be aware of any of your refinements (unless you like, monkey patch the factory) so it's basically worthless imo

in this case the class that's getting monkey patched doesn't even need to be aware of the poo poo that's being patched into it, so best thing is to keep it all in the module that would actually use it and leave the original class alone

the team here at redhat seems to like ruby a lot. I'm excited to see whether that's because ruby is OK when used responsibly, or whether that's because they haven't gone very far down the rabbit hole yet.

here's hoping it's the former. i like ruby as long as nothing i'm using abuses the hairer language features too much (qv our last few posts)

that's probably true of any language, though. especially dynamic ones

ruby seems great at first. the hash syntax seems really nice, the higher order functional methods are nice and work well, yield syntax is legitimately pretty great.

then you realize that there are actually two hash syntaxes and { 'foo' => 'butts' } and { foo: 'butts' } seeming more or less the same, since in both cases you're defining a key foo that points to butts, they are actually two totally different keys. and then 5 monhts later you're calling hash.with_indifferent_access! on everything and getting really comfortable with the idea of your code being generally nondeterministic,

lol if ur hash keys are strings instead of symbols

sure i can do that if i'm implementing a new thing I am free to do that, or just use like something besides restclient (i mean lol at not using faraday anyhow), but that doesn't fix all of the things using restclient where I know the people who implemented them had no idea the money patches existed but were using the patches anyhow. it means i have to go and track all of those people down and be like 'hey did you know all calls to restclient sometimes have a timeout of 100s and sometimes have a timeout of 0s, depending on whether or not this code has been sourced??? what should i Do??

sorry for your interfaces and bad coworkers

the real question isn't if operators should be surrounded by whitespace but whether the full unicode category for spaces [Zs], including the OGHAM SPACE MARK (  ) such that a-b is an identifier but a - b is actual subtraction

# ? Jun 6, 2015 23:49

sarehu: Apr 20, 2007; (call/cc call/cc)

a - b is an identifier, a − b is subtraction.

# ? Jun 7, 2015 00:11

sarehu: Apr 20, 2007; (call/cc call/cc)

Also a – b is a closed range, a — b is a half-open range.

Back on the topic of unary minus, my biggest Haskell pet peeve is the difference between map (+1) [1,2,3] and map (-1) [1,2,3].

# ? Jun 7, 2015 01:36

sarehu: Apr 20, 2007; (call/cc call/cc)

There's a simple workaround: map ((0-) . (+ 1) . (0-)) [1,2,3]

this is incredibly ugly and its not at all obvious what it does. map (+ (-1)) [1,2,3] is much better

# ? Jun 7, 2015 02:52

VikingofRock: Aug 24, 2008

I think the best workaround is map (subtract 1) [1,2,3] (no symbolic operators; shoutout to NBSD!). Still pretty annoying IMO.

IEnumerable is also lazily evaluated.

code:

//select returns an IEnumerable<int> which features lazy evaluation
//some basic type inference allows you to not explicitly specify the type here in a local scope
var someEnumerable = new List {1, 2, 3}
    .Select(x => x - 1);

//do some stuff. someList hasn't evaluated yet. someList doesn't evaluate until you need to iterate over it to produce some value(s)
...

var firstValue = someEnumerable.First(x => x > 0); //enumerate only until the first matching is found and then stop enumerating

the "correct" way to monkey patch poo poo in ruby is to use ruby 2.1 "refinements." it's like a monkey patch, scoped to files that include the refinement

the evaluation order and behavior are predictable, and it can't gently caress up code that isn't yours

yeah but they're useless for any class that you dont instantiate directly, eg. most classes.

you shouldn't be altering classes you don't/can't instantiate

make a wrapper instead i guess

i agree with you but that doesn't stop people from doing it, and if they're going to do it, i'd like them to be doing it through refinements rather than breaking poo poo for everyone in the codebase
