|
|
|
|
1. Introduction
|
|
|
|
This extension module adds ruby a functionality to execute an
|
|
arbitrary command through pseudo tty (pty).
|
|
|
|
2. Install
|
|
|
|
Follow the instruction below.
|
|
|
|
(1) Execute
|
|
|
|
ruby extconf.rb
|
|
|
|
then Makefile is generated.
|
|
|
|
(3) Do make; make install.
|
|
|
|
3. What you can do
|
|
|
|
This extension module defines a module named PTY, which contains
|
|
following module fungtions:
|
|
|
|
getpty(command)
|
|
spawn(command)
|
|
|
|
This function reserves a pty, executes command over the pty
|
|
and returns an array. The return value is an array with three
|
|
elements. The first element in the array is for reading and the
|
|
second for writing. The third element is the process ID of the
|
|
child process. If this function is called with an iterator block,
|
|
the array is passed to the block as block parameters, and the
|
|
function itself returns nil.
|
|
|
|
When the child process is suspended or finished, an exception is
|
|
raised. If this function is called with an iterator block,
|
|
exception is raised only within the block. Child process
|
|
monitor is terminated on block exit.
|
|
|
|
protect_signal
|
|
reset_signal
|
|
|
|
These functions are obsolete in this version of pty.
