Add list command #1113

baduker · 2023-09-19T08:43:26Z

List all Exercism tracks, exercises implementation, and download selected exercises.

What does this PR do?

The PR implements a feature in the exercism-cli for listing all the available Exercism tracks and exercises based on the given track and difficulty level. It also allows the users to download the list of exercises for a specific track and difficulty level.

Changes Made:

Added a new command, list, to the CLI. This command can take the following flags --track, --all, --level, and --download.
Implemented validation of the track names and difficulty levels using predefined maps and sets.
Added a new feature to download all the exercises for a given track and difficulty level, provided the user is eligible for given exercises
Implemented sorting of exercises based on difficulty.
Updated the CLI documentation to add the usage of the list command.
Refactored downlaod.go command for readability
Added new function MakeRequest to api.go

Related Issue:

Resolves #992
Resolves #718

How to test it?

Check out the feature branch (on my fork): add-list-command
Run go build exercism/main.go
Run ./main configure --token=YOUR_TOKEN_VALUE

Start testing the new command.

Note: the results will be different because the CLI shows tracks and exercises available to a given user.

List your tracks: Run ./main list

This should return:

Hello. Thanks for opening a PR on Exercism. We are currently in a phase of our journey where we have paused community contributions to allow us to take a breather and redesign our community model. You can learn more in this blog post. As such, all issues and PRs in this repository are being automatically closed.

That doesn't mean we're not interested in your ideas, or that if you're stuck on something we don't want to help. The best place to discuss things is with our community on the Exercism Community Forum. You can use this link to copy this into a new topic there.

Note: If this PR has been pre-approved, please link back to this PR on the forum thread and a maintainer or staff member will reopen it.

iHiD

Thanks for your work on this. I've reopened the PR :)

I have three general comments:

I really like the list functionality. I'm 👍 on adding that.
I don't love the download all functionality, as that has the downside of marking all those exercises in progress. I'd like to have a wider community discussion about that first, and also take time to consider it from a product perspective.
There are quite a few other changes in this PR that make it hard to see exactly what's going on where. I've added questions to those for clarification.

Action suggestions:

I think there are three seperate PRs here.
a) The refactorings
b) The addition of List
c) The addition of Download

I'd like to see a PR just for (b) and potentially one for (a) to start with. Those will be more manageable to review. In its current state, there's so much happening in this PR, I think it will take a long time to get a proper review. I'd like to get the List stuff reviewed properly instead and be ale to deploy that, without waiting on the rest to get reviewesd.

The List functionality also needs a comprehensive test adding.

Thanks for your work on this. I hope that makes sense!

Why does this change?

This and all the other changes you mention below is a poor attempt at "fixing" the broken tests on master. Additionally, I need to revert some of the changes that fix deprecated code, mostly from the io/ioutil to io and os packages.

As far as I can see, all tests on main are green: https://github.com/exercism/cli/actions/runs/6098825660/job/16549554194

According to CONTRIBUTING.MD you can run tests locally with go test ./... and this fails on a clean clone and master. I get this:

pwd && go test ./... /Users/baduker/Downloads/cli ? github.com/exercism/cli/browser [no test files] ? github.com/exercism/cli/exercism [no test files] ok github.com/exercism/cli/api 0.254s ok github.com/exercism/cli/cli 0.315s --- FAIL: TestSubmitFiles (0.01s) Error Trace: submit_test.go:275 Error: Not equal: "This is file 2."

Do you mean master or main? The primary branch on this repo is main.

Yes, I meant main, not master.

Hmmm, I don't know why that's not working on your machine when it is working on our CI. Maybe a different version of Go? CCing @junedev, @andrerfcsantos, @kytrinyx and @ErikSchierboom to see if they have any ideas :)

@iHiD @ErikSchierboom the failing tests happen when using a version of Go 1.17 and above. There was a change to the mime/multipart pkg that changes the file path information being returned for any files included in the mocked request. It looks like there's an open PR for this issue #1066 that can be merged in.

I've replied there. I'd appreciate eyes on that too pls :)
