I've released version 2.0.4 of PyFilesystem.

PyFilesystem is an abstraction layer for filesystems (or anything that resembles a filesystem). See this post for more details.

This version adds support for Python3.6 os.pathlike to the OSFS class. This is in oft-requested feature, but it only affects the OSFS constructor; since FS methods use a standardized path format.

Also in the version is a contribution by Martin Larralde which implements an elegant extension mechanism. Essentially, if you layout your filesystem implementation according to the convention, then PyFilesystem will be aware of it automatically. So open_fs('awesomefs://foo/bar') would work without explicitly adding awesomefs to the core library. continue reading…

I'd like to announce the first official release of Lomond, a new WebSocket client library for Python. The development was sponsored by Dataplicity.

Lomond is not the first websocket client for Python, so why go to the effort of building another one? For our purposes, we needed a stand alone client that didn't need a framework to run. So that excludes the websocket client support in Tornado, aiohttp etc. The two libraries that were suitable for our product, websocket-client and ws4py, both had show-stopper bugs with ssl support; websocket-client would sometimes refuse to processes packets until additional data was received, and ws4py could lose entire packets. I'm sure both libraries could be fixed, but neither project appears to be actively maintained. continue reading…
