Actually, the code "branches" four times. Three times you introduce possible failure, the original parse as well as each call to flatMap. It flattens each of these possible failures into one, though, so you don't have to thin

Nice because it is readable but I generally dislike clever/elegant solutions for fizzbuzz. Here is my own clever haskell solution: module Raindrops (convert) where import Control.Monad (liftM2) import Data.Foldable(fold) impo

Also, when using his amazing git plugin (fugitive) to commit you get very useful highlighting when you break these conventions. http://i.imgur.com/8ix5JGa.png

There were also some games where the player just runs faster when holding both w and up arrow on the keyboard plus forward on the controller. Not that anyone but speed runners actually would do this to themselves.

In rust you can use pattern matching in arguments: struct Foo { x: f64, y: f64, z: f64 } fn length(Foo {x, y, z}: Foo) -> f64 { (x*x + y*y + z*z).sqrt() } ...Doesn't work with `self` because that would be im

It is basically a hack to export the type but not the type constructor. It stops people from doing things like let new_socket = OpenSocket { port: 12 };

I mean, pressing the button to collapse the documentation isn't very hard http://i.imgur.com/rcI3JG5.jpg I never had to print an osstr yet but it seems fairly straightforward when looking at the docs? There are three o

There are basically three ways to do meta programming in nim. Simple replacement of tokens: const debug = true template log(msg: string) = if debug: stdout.writeLine(msg) You could also use other concrete types, generics

It gives a pretty facinating point of view onto computation in general. You only the ability to define and call functions. Functions can only recombine their input. And somehow it is still as powerful as, say, python! Don't need some b

Very cool. I always wanted to play around with a git provider for powershell. Powershell's syntax is great for queries and you could use everything that works on the normal file system with anything that has the abstractions implemente

The simplest example would be a persistent list. Think you first create a list [c,d,e]. You can safely share references to that. Then you attach a to one version and b to another: a \ c-d-e b / The memory for the o

But at least they shouldn't use phrases like `persistent sets` in the documentation. I confused that with the datatype on my first reading. Technical details are necessary but that is just creating unnecessary confusion. Compare that t

It is very close to vi/vim's philosophy - different modes for different task, key bindings are mnemonics, you combine basic commands to more complex tasks. Even window manipulation is the same with the hierarchy of content->s

Do you happen to know how japanese input methods generally work? I have seen chinese and japanese steno machines before, e.g. chorded strokes that cover one or more sillables. That takes specific hardware and a bunch of training, though, so

It is much more like haskell's pattern matching. Notably it handles tagged unions (in rust enum). Here is a good example from the [book]( https://doc.rust-lang.org/book/match.html ): enum Message { Qui

I think for many that is a hard drive thing combined with dozens of tool bars, though. Phones have solid state memory so that shouldn't be a major problem.

That is odd, powershell shells out to cmd.exe if you try to pipe binary or text data. It goes back to powershell only if you use powershell commands in the pipeline. If you don't pass the flags zo handle it as binary in those cases stu

Currently powershell just shells out to cmd.exe to run normal command line apps And handle text streams anyway. How would that work?

I only used nim for some side projects but the only times I saw this used anywhere is in FFI bindings. That way you can mirror, say, C style while writing the bindings either manually or automatically and use them as if they were normal nim

Didn't this happen for spellings in various ortography reforms? I think german had the largest one in recent years and iirc there was a deprecation period for old spellings. An English spelling reform would be a blessing but almost cer

It is more that unix shells are built on piping and piping is systematically broken in unix shells. It just becomes extremely obvious after using for powershell for any time which doesn't require most of the work to scrap and rewrite o
