crpty

Use forkpty(3) from Crystal.

Note: this library is only an experiment/learning project for now. Only tested on Ubuntu 20.04 LTS 64-bit. Requires gcc to compile.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     crpty:
       github: federicotdn/crpty
   

2. Run shards install

Usage

require "crpty"

result = CrPty.fork_pty()

if result.pid == 0
  # Child process!
  # Do something like e.g. exec() to Bash
else
  # Parent process!
  # `result.master_fd` points to the master side of the pseudoterminal
  master_fd = IO::FileDescriptor.new result.master_fd
  
  # e.g. Copy bytes from STDIN to master_fd and from master_fd to STDOUT
end
