Overview
PyWinpty allows creating and communicating with Windows processes that receive input and print outputs via console input and output pipes. PyWinpty supports both the native ConPTY interface and the previous, fallback winpty library.
Dependencies
To compile pywinpty sources, you must have Rust installed.
Optionally, you can also have Winpty's C header and library files available on your include path.
Installation
You can install this library by using conda or pip package managers, as it follows:
Using conda (Recommended):
conda install pywinpty
Using pip:
pip install pywinpty
Building from source
To build from sources, you will require both a working stable or nightly Rust toolchain with
target x86_64-pc-windows-msvc
, which can be installed using rustup.
Optionally, this library can be linked against winpty library, which you can install using conda-forge:
conda install winpty -c conda-forge
If you don't want to use conda, you will need to have the winpty binaries and headers available on your PATH.
Finally, pywinpty uses Maturin as the build backend, which can be installed using pip
:
pip install maturin
To test your compilation environment settings, you can build pywinpty sources locally, by
executing:
maturin develop
This package depends on the following Rust crates:
- PyO3: Library used to produce Python bindings from Rust code.
- WinPTY-rs: Create and spawn processes inside a pseudoterminal in Windows from Rust.
- Maturin: Build system to build and publish Rust-based Python packages.
Package usage
Pywinpty offers a single python wrapper around winpty library functions.
This implies that using a single object (winpty.PTY
) it is possible to access to all functionality, as it follows:
from winpty import PtyProcess
proc = PtyProcess.spawn('python')
proc.write('print("hello, world!")\r\n')
proc.write('exit()\r\n')
while proc.isalive():
print(proc.readline())
from winpty import PTY
cols, rows = 80, 25
process = PTY(cols, rows)
process.spawn(br'C:\windows\system32\cmd.exe')
process.read()
process.write(b'Text')
new_cols, new_rows = 90, 30
process.set_size(new_cols, new_rows)
alive = process.isalive()
del process
Running tests
We use pytest to run tests as it follows (after calling maturin develop
), the test suite depends
on pytest-lazy-fixture, which can be installed via pip:
pip install pytest pytest-lazy-fixture flaky
All the tests can be exceuted using the following command
python runtests.py
