Way to use wsl utilities on windows 10 with emacs windows version.

Way to use wsl utilities on windows 10 with emacs windows version.

[范凯]

Dear list,


As we known Emacs relays on many unix tools such as zip, unzip, hunspell, ispell, diff, etc.



Historically to use these kind of tools in Win32 emacs, one have to use cygwin or download them from gnu-win32 project on sf.net.



As recently MS had released the Windows Subsystem for Linux, aka. WSL. and it is able to run any linux commandline tool in windows command shell by calling "wsl" command then append the original wanted command line (include its arguments) as wsl's command arguments. eg.


say I want to get the different of filea.txt and fileb.txt in current directory, I can run following command in cmd.exe


wsl diff -u filea.txt fileb.txt


Then linux diff tool will be run and print the diff result to cmd.exe output buffer.




QUESTION: Has anyone successfully configured wsl related command in win32 emacs? Are there anyway to use this mechanism globally in win32-emacs, say prefix every command line utility with a wxl?

Several weeks ago there were headlines in the IT
news newmedia saying Microsoft has a plan for a
Terminal tool.  Apparently wsl is 2x or 5x slow

If memory serves the wsl is 5x slower and the wsl2 is 2x slower. The filesystem layer was where I.T. was swimming in the mud like a Corporate Capitalist Pig (CCP) producing onetime use plastics waste at unprecedented scale.

I mention their Terminal plan only because it makes much much more sense architecturallythan the shoehorn-vm trick.

Totally agree. Currently WSL is okfor terminal and very light stuff.

M-x rmail RET is quite slow at incorporating new mails (+ saving the
RMAIL file).

Hopefully this will change both with WSL2 & this terminal for day to
day hacking.
