lpty is a module that allows a program written in lua to open the master side of a PTY and start a program with the slave side of the PTY as its controlling terminal. The PTY may then be read from and written to, thus controlling the remote program.
added getfd method to retrieve the file descriptor of the pty's master side. This has been contributed by Matthew Wild (mwild1 at gmail dot com).
His rationale, which I can completely get behind, is this:
Having the method name 'getfd' is good, as it makes the pty objects compatible with LuaSocket objects. This means you can pass the pty directly to socket.select()! (it probably works with LuaEvent too, but I haven't tested).
I have tested it with luaposix' poll() and that works fine.
You may also want to read up on how PTYs work by consulting the pty(7) manpage. A more extensive treatment of the matter can be found here
You can get lpty-1.1 by clicking on this link, or by installing it from the luarocks repository. If you fetch it from here, the included README gives hints on how to build it.
