Avi, For my use 1) the salutation and email address (always with an '@') are sequential and 2) I'm developing the script to extract both from the same file. Regards, Rich

PyDev 12.0.0 Released
by Fabio Zadrozny Feb. 4, 2024

Feb. 4, 2024

PyDev 12.0.0 Release Highlights - *Debugger* - *sys.monitoring* is now used in Python 3.12 (and it's *much* faster than any previous version). - A new setting was added in the *Preferences > PyDev > Debug* to debug *just my code* (meaning that when stepping it will just step into files under PyDev source folders). - Improved the step into function (activated with *Ctrl+Alt* then *Click function* to step into). - Support for Python 3.6 and 3.7 was dropped (only Python 3.8 onwards is now supported). - *Ruff* - Ruff can now be used as a code formatter. - The latest ruff (*0.1.x*) is now supported (as it broke backward compatibility in its *0.1.0* version). - *Code Analysis* - Fixes in semantic analysis to better determine if strings in annotations should be checked for symbols or not. Note: *Only Python 3.8 onwards is now supported* * *Python 3.6* and *3.7* support is now *dropped* (please use *PyDev 11.0.3* if you still use it). About PyDev PyDev is an open-source Python IDE on top of Eclipse for Python (also available for Python on Visual Studio Code). It comes with goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, interactive console, etc. It is also available as a standalone through LiClipse with goodies such as multiple cursors, theming and support for many other languages, such as Django Templates, Jinja2, Html, JavaScript, etc. Links: PyDev: http://pydev.org PyDev Blog: http://pydev.blogspot.com PyDev on VSCode: http://pydev.org/vscode LiClipse: http://www.liclipse.com PyVmMonitor - Python Profiler: http://www.pyvmmonitor.com/ Cheers, Fabio Zadrozny

Thomas, A bash shell script looks easier for me and more promising. Using a while loop (one for the name file the other for the address file), and sed for putting the name at the head of the message replacing a generic placeholder should work with the existing for loop script. Thanks, Rich

The docu tells me: Windows loop.add_reader() and loop.add_writer() only accept socket handles (e.g. pipe file descriptors are not supported). https://docs.python.org/3/library/asyncio-platforms.html Alternatives are aiofiles and anyio and maybe more, but not sure whether they span all platforms, i.e. unix, windows and mac or whether they have similar restrictions. Theoretically on Windows IOCP should also cover file handles: https://en.wikipedia.org/wiki/Input/output_completion_port Its use by libuv the basis for node.js.

I am still waiting for async files in the style of nodejs that works on windows and is bundled with the main python distribution. I am not very fond on doing something like adding listeners to a file descriptor, in nodejs async files are based on callbacks not on listeners. Whats the roadmap here?
