Sort List elements in Elixir Lang


Tag: elixir

I have a list of strings that I want to order in two ways.

  1. Alphabetically
  2. By string length


To sort a list of strings alphabetically, you can just use Enum.sort/1, which will order items by their default order (which is alphabetic ordering for strings).

iex> Enum.sort(["b", "aaa", "cc"])
["aaa", "b", "cc"]

To sort a list by a different property, such as string length, you can use Enum.sort_by/2, which takes a mapper function as second argument. The values will then be sorted by the result of this function applied to each element.

iex> Enum.sort_by(["b", "aaa", "cc"], &String.length/1)
["b", "cc", "aaa"]


Step List With Elixir

Can someone please provide a suggestion on how to iterate a list BUT with a batch of x at a time? For example: If the functionality existed: ["1","2","3","4","5","6","7","8","9","10"].step(5)|> IO.puts Would produce in two iterations: 12345 678910 I believe Stream.iterate/2 is the solution but my attempts to do so given an...

When to use compile-only dependencies in Elixir

Why Rem operator in Elixir returns negative numbers?

How does Polymorphic association work with Ecto?

Ecto seems to support polymorphic association as I read through https://github.com/elixir-lang/ecto/issues/389 and its related issues linked from it. Let's say I need a Comment model association on Task and Event models. If my understanding of Ecto association with custom source is right, then we need four tables and three models,...

Most efficient way to search file for byte patterns in Elixir

I am searching for id3 tags in a song file. A file can have id3v1, id3v1 extended tags (located at the end of the file) as well as id3v2 tags (usually located at the beginning). For the id3v1 tags, I can use File.read(song_file) and pull out the last 355 bytes...

Where does Elixir/erlang fit into the microservices approach? [closed]

Lately I've been doing some experiments with docker compose in order to deploy multiple collaborating microservices. I can see the many benefits that microservices provide, and now that there is a good toolset for managing them, I think that it's not extremely hard to jump into the microservices wagon. But,...

What is the number that shows up after you define an anonymous function in elixir?

When you define an anonymous function in elixir you get a result like this. #Function<6.90072148/1 in :erl_eval.expr/5> What I've noticed is that the number is based on the arity of the function. So a 1 arg function is always #Function<6.90072148/1 in :erl_eval.expr/5> A two arg function is always #Function<12.90072148/2 in...

Why the syntax for defining sigils in Elixir doesn't use “defsigil”?
