rustlings watch halts when starting to edit file with emacs

[tanj]

When ever I start to edit a file with emacs rustlings watch ends with ★ All exercises completed! ★

GNU Emacs 27.1 (build 1, x86_64-w64-mingw32) on Windows 10 Pro Version 10.0.19042 Build 19042

Steps to reproduce:

1. % /c/Program\ Files/Emacs/x86_64/bin/runemacs.exe -Q
2. Run rustlings watch in external shell (not in emacs)
3. Open rustlings/exercises/variables/variables1.rs
4. Insert any text (no save needed)
5. rustlings watch ends with ★ All exercises completed! ★

Looks like it is related to this https://stackoverflow.com/questions/5738170/why-does-emacs-create-temporary-symbolic-links-for-modified-files

Seems this is as issue for npm as well.

It seems to be fine if the file exists when rustlings watch starts. So it must have something to do with the creation of the symlink that causes the program to end.

The solution seems to be to not create lock files by setting (setq create-lockfiles nil) in .emacs or other init file locations.

I'm not sure if there is a way to handle this in the rustlings app. If you don't feel it's in your scope to fix feel free to close this.

What's the filename of those symlinks? Do they still have a .rs extension by any chance? If that's the case, it would confuse rustlings watch.

[tanj]

the symlinks named with the file name and prepended with .# So variables1.rs would create a symlink as .#variables1.rs

Sorry, should have asked before: which version of rustlings are you using?

Could you please try the latest release? We introduced some changes in #599 that I think will fix your issue.

Oh, I didn't realize you weren't using the master branch and had switched to main.

I originally installed via the command curl -L https://git.io/rustlings | bash which I got from this repo's README.md

that git.io link currently points to https://raw.githubusercontent.com/rust-lang/rustlings/master/install.sh

Tested with the head of main 0d894e6 and the problem is resolved.

Thanks for your help
