winpty
|
|
======
|
|
|
|
winpty is a Windows software package providing an interface similar to a Unix
|
|
pty-master for communicating with Windows console programs. The package
|
|
consists of a library (libwinpty) and a tool for Cygwin and MSYS for running
|
|
Windows console programs in a Cygwin/MSYS pty.
|
|
|
|
The software works by starting the ``winpty-agent.exe`` process with a new,
|
|
hidden console window, which bridges between the console API and terminal
|
|
input/output escape codes. It polls the hidden console's screen buffer for
|
|
changes and generates a corresponding stream of output.
|
|
|
|
The Unix adapter allows running Windows console programs (e.g. CMD, PowerShell,
|
|
IronPython, etc.) under ``mintty`` or Cygwin's ``sshd`` with
|
|
properly-functioning input (e.g. arrow and function keys) and output (e.g. line
|
|
buffering). The library could be also useful for writing a non-Cygwin SSH
|
|
server.
|
|
|
|
Prerequisites
|
|
=============
|
|
|
|
You need the following to build winpty:
|
|
|
|
* A Cygwin or MSYS installation
|
|
* GNU make
|
|
* A MinGW 32-bit g++ toolchain, v4 or later, to build ``winpty.dll`` and
|
|
``winpty-agent.exe``
|
|
* A g++ toolchain targeting Cygwin or MSYS, v3 or later, to build
|
|
``console.exe``
|
|
|
|
Winpty requires two g++ toolchains as it is split into two parts. The
|
|
binaries winpty.dll and winpty-agent.exe interface with the native Windows
|
|
command prompt window so they are compiled with the native MinGW toolchain.
|
|
The console.exe binary interfaces with the MSYS/Cygwin terminal so it is
|
|
compiled with the MSYS/Cygwin toolchain.
|
|
|
|
MinGW appears to be split into two distributions -- MinGW (creates 32-bit
|
|
binaries) and MinGW-w64 (creates both 32-bit and 64-bit binaries). Either
|
|
one is acceptable, but the compiler must be v4 or later and produce 32-bit
|
|
binaries.
|
|
|
|
Cygwin packages
|
|
---------------
|
|
|
|
The default g++ compiler for Cygwin targets Cygwin itself, but Cygwin also
|
|
packages MinGW compilers from both the MinGW and MinGW-w64 projects. As of
|
|
this writing, the necessary packages are:
|
|
|
|
* Either ``mingw-gcc-g++`` or ``mingw64-i686-gcc-g++`` (but not
|
|
``mingw64-x86_64-gcc-g++``)
|
|
* ``gcc4-g++``
|
|
|
|
MinGW packages
|
|
--------------
|
|
|
|
The default g++ compiler for MinGW targets native Windows, but the MinGW
|
|
project also packages compilers to target the MSYS environment itself. The
|
|
required packages are:
|
|
|
|
* ``mingw32-make``
|
|
* ``g++``
|
|
* ``msys-dvlpr``
|
|
|
|
|
|
Build
|
|
=====
|
|
|
|
In the project directory, run ``./configure``, then ``make``.
|
|
|
|
This will produce three binaries:
|
|
|
|
* ``build/winpty.dll``
|
|
* ``build/winpty-agent.exe``
|
|
* ``build/console.exe``
|
|
|
|
Using the Unix adapter
|
|
======================
|
|
|
|
To run a Windows console program in ``mintty`` or Cygwin ``sshd``, prepend
|
|
``console.exe`` to the command-line::
|
|
|
|
$ build/console.exe c:/Python27/python.exe
|
|
Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32
|
|
