cli + matching-brackets: Exercise files are not downloaded

[nkanderson]

Running exercism download --exercise=matching-brackets --track=rust on my computer does not seem to download any of the exercise files, like the src and test directories, README.md, etc. I've been able to download other exercises successfully.

The matching-brackets directory itself is created, as is the .exercism directory within it. I don't get any error message, just the typical Downloaded to <my exercism rust track directory>/matching-brackets.

I initially encountered the issue with the exercism cli version 3.0.11. Tried upgrading and hit the same thing with 3.0.12. My OS info as reported by exercism troubleshoot is the following:

Operating System
----------------
OS:           darwin
Architecture: amd64

I'm not sure if this issue belongs on the project for the exercism CLI - it seems specific to this one exercise, so I thought I'd start here.

Hmm. I couldn't replicate this locally:

There is one possibility I can think of which might be causing this behavior for you: in #819, the exercise was renamed to bracket-push. It should have retained backwards compatibility, though.

It may be worth trying exercism download --exercise=bracket-push --track=rust. If that also fails, then I would suggest moving this issue to https://github.com/exercism/configlet.

[nkanderson]

Oh, that renaming is interesting, and definitely seems like it could be related. My initial setup of exercism is fairly old (first installed Oct 2017), and I've downloaded all the Rust exercises over time. But since there are fairly regular updates, I usually download again just before working on one.

And as it turns out, I already have a bracket-push exercise downloaded. I tried moving the bracket-push directory out of my exercism directory, and I get the same result as above when attempting to download matching-brackets.

I may try to replicate this on another machine, and I'll take a look at that configlet project as well.

[coriolinus]

Don't worry about configlet; that was a mistake on my part. I meant to link you to https://github.com/exercism/cli.

[nkanderson]

Ok, thanks. I've confirmed this is an issue on another system, with a fresh install of exercism, so I'll create an issue on the cli project.
