Pipes

Unix pipes are a powerful tool. In Emacs we don't have much support for them so this package aims to add such support.

API

The Pipe API consists of a few functions and macros to spawn processes and communicate with them in the Pipe style.

pipe

A macro allowing piping to be represented simply:

(pipe "ls -la"
  (catch :eof
    (with-current-buffer somebuf
      (-each
       (->> (pipe-read)
         (-keep (lambda (a) a)))
       (lambda (x) (print x)))

pipe takes a command as a string and a body of code which is executed with (pipe-read) providing a line from the command.

pipe-eof proc

Has proc been marked EOF?

pipe-shell-command command thunk &optional name

Pipe the shell command to the thunk function.

Within thunk the function pipe-read is bound to deliver whatever came over the pipe.
