Python streamexpect, truly cross-platform expect library

In plain words

Python streamexpect is a library that provides expect-like functionality for generic Python streams and sockets across platforms. Unlike similar tools that require underlying files or TTYs, streamexpect uses duck-typing and only needs a read or recv method, making it more flexible. It works with any Python stream, includes extensive unit testing, and is installed via pip. The library is designed for developers who need to automate interactions with streams and sockets in a cross-platform way.

streamexpect is a library providing cross-platform "expect-like" functionality for generic Python streams and sockets . It is similar to the Pexpect library, except where Pexpect explicitly requires an underlying file (usually a TTY), streamexpect uses duck-typing and requires only a read or recv method. The original version of streamexpect was generously donated by Digi Wireless Design Services . The software is provided as Alpha software and has not undergone formal testing. It does, however, ship with extensive unit testing. Installation is performed using pip. The latest released version of streamexpect can be obtained with the following command: The following example shows opening a…from pypi.python.org

  Hi HN! This is my pet project, written from scratch because there is so much to discover and learn in the process. The focus is on simplicity and incremental updates. Progress is slow because I do not have much spare time to work on this, but I would love to hear some feedback. Regards

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
