【WSL2】 zsh-syntax-highlighting Very low speed on WSL2

@BigTear

In /etc/wsl.conf (create if it doesn't exist) add:

[interop]
appendWindowsPath=false

Afterwards run wsl --shutdown and open a new session for the changes to take effect. Note that this will mean Windows executables are no longer in your PATH, e.g., commands like code will no longer work. I think this is better anyway bc it unclutters your WSL PATH and could prevent any problems arising from using the Windows version of something accidentally when you meant to use the Linux version. However, you will manually need to re-add all the Windows executables you care about, like code either:

by creating an alias for the executable

alias code="/mnt/c/[your vscode installation directory]/bin/code"

or by creating a new script that redirects code to the executable

#!/usr/bin/env bash

/mnt/c/[your vscode installation directory]/bin/code "$@"

Also if you do that latter, remember you need to run chmod +x on it and make it available in your PATH for it to be executable from anywhere.

e.g.

# assuming "$HOME/.local/bin" exists and is on your PATH...
echo -e '#!/usr/bin/env bash\n/mnt/c/[your vscode installation directory]/bin/code "$@"' > "$HOME/.local/bin/code"
chmod +x "$HOME/.local/bin/code"

You could also just re-add the executable directory to your PATH variable, but I think that defeats the purpose of cleaning /mnt/* entries from your PATH.
