mkfifo

This small library monkey patches File to add two new class methods: fifo and fifo?.

I made this because:

1. I need it for my hobby project
2. I found this dicussion about it, so others need it too

It's basically a copy of Ruby's File.mkfifo, but I changed the permissions to match Crystal's default for new files.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     mkfifo:
       github: tijn/mkfifo
   

2. Run shards install

Usage

require "mkfifo"

path = File.tempname
File.mkfifo(path)
File.fifo?(path) # ==> true

# read from the fifo, for example
File.each_line(path) do |line|
  puts line
end

# or write to it:
File.open(path) do |fifo|
  fifo.puts("foo and bar")
end

Alternatives

I just found fifo.cr which takes a different approach, that is arguably somewhat cleaner since it avoids monkey patching.
