I want to "pipe" the output of the cat
command into an Elixir Mix Task and hold it in a variable as a binary.
I have already tried using the IO.gets/1
, but it reads just the first line of the output.
cat textfile.txt | mix print
defmodule Mix.Tasks.Print do
use Mix.Task
def run(_argv) do
Task.async(fn -> IO.gets("") end)
|> Task.await(t)
|> IO.puts() # prints the first line
end
end
I want to get hold of the whole file's contents in a binary variable in Elixir and print it to the console, but I get just the first line. I'd expect Elixir to have some built-in solution, to end on EOF.
There is a IO.read/2 function I was looking for.
defmodule Mix.Tasks.Print do
use Mix.Task
def run(_argv) do
IO.read(:all)
|> IO.puts() # prints all lines
end
end
