improve open cmd #788

Smarticles101 · 2019-01-07T17:04:17Z

This pull request aims to improve the open command.

I start by solving #460, while diving into the open command, I found that it could be improved in a few various ways.

cmd/open.go

I think this is ready for review now, I've made the changes I feel best for consistency with the download command. I'll add tests after it's reviewed to make sure everything is how we want.

+				continue
+			}

+			if meta.Team != teamID {


Initially, I tried teamID != "" && meta.Team != teamID, but the current boolean statement is more in line with how the api handles team exercises.

Would you mind extracting this change into a separate PR? (We should probably include tests for the change).

I completely failed to keep up with my Exercism notifications, and I'm inexcusably late to the party. To add to this, my laptop crashed and is now in for repair, and as of today I have a loaner that I've not quite gotten set up to be usable. So. My apologies (first) and (second)... my goal is to get through all the open PRs in the CLI track over the course of the next week. So sorry to leave you hanging!

Don't worry about it too much! Things happen and I'm pretty sure most people here are guilty of ignoring notifications for a long time. Completely understandable

Hey @Smarticles101 -- overall it looks like what you have here is much better.

In order to help me review this properly, would you summarize exactly what changed, and how this will change the usage of the command?

Smarticles101 · 2019-02-26T23:49:57Z

@kytrinyx
The old open command worked in a way similar to this:

exercism open ./path/to/exercise/folder

The new command, rather than using an exercise path, follows a style similar to the other commands. Now instead of passing an exercise directory, you pass a slug.

exercism open --exercise slug

I also added support for --team, --track, and --remote from #460 .

kytrinyx · 2019-02-27T00:39:41Z

Thank you, that's really helpful!

In order to not break people's work flow we'll need to support the original usage as well, though... at least until we do a major version bump.

Smarticles101 · 2019-02-27T02:36:46Z

@kytrinyx That sounds good, I can add that back in when I have free time tomorrow

Smarticles101 · 2019-02-28T14:32:03Z

@kytrinyx original usage is supported now :)

Smarticles101 · 2019-02-28T14:51:28Z

No idea why the build is failing, I haven't changed anything that should make it fail, and I've rebased against master and compiled it locally and it seems to work?

kytrinyx · 2019-02-28T15:13:34Z

w000p!!!!

I'll take a look.

This needs to be meta.ExerciseSlug to pass the tests (see #815)

This is looking really good. I have a few suggestions, but overall I think this is doing the right thing!

+	teamID, _ := flags.GetString("team")


I know error checking seems tedious, but I'd rather we did it for completion. If it gets really bad we can extract it into a validator type, but for now let's just do it inline.

Let's name this exerciseSlug for consistency with the rest of the codebase (we don't currently call it exerciseID anywhere).

Cat we go with just team as the variable name? We don't call this teamID anywhere else.

How about extracting args[0] into a variable path up at the start where we're also extracting from flags?

var path string if args.length > 0 { path = args[0] }

That way down here we can say if path != "" {

If we want to be really explicit, we could also have a validation on path != "" and exerciseSlug != "" and explain that you need one or the other.

Let's extract the remote flag up top as well, and check the error.

Would it make sense to use the api error decoder helper?

cli/cmd/cmd.go

Line 78 in c3525cf

func decodedAPIError(resp *http.Response) error {

I need to decode the json anyways for the solution url. The helper only returns the error. Would it be beneficial to introduce a helper that decodes the entire api response?

Hm. Maybe, but let's hold off on that for now.

I wonder if we can make the error decoder helper smarter and add this logic into it.

cli/cmd/cmd.go

Line 78 in c3525cf

func decodedAPIError(resp *http.Response) error {

(If so, let's do that in a separate PR and get that into master quickly so we can use it elsewhere).

Let's open the URL and return here so that we can out-dent the else.

I made a mess of my git tree today and ended up having to cherry-pick my commits out.

I updated it to use ExerciseSlug now so the build passes. I'll see when I have time to look into your other comments. I should get some time early next week

kytrinyx · 2019-03-03T16:54:17Z

@Smarticles101 just a quick note to say that I think the next step here is to rebase onto master before I do another review. If I'm wrong about that please let me know :-)

now you just give the exercise name instead of path

kytrinyx · 2019-03-15T15:49:00Z

@Smarticles101 Is this ready for another round of review?

kytrinyx

The current logic around path or slug is a bit confusing, so I've suggested an improvement there.

We're also going to need to fix the long description for the command.

kytrinyx · 2019-03-15T15:54:22Z

+			return fmt.Errorf("must provide an --exercise slug or an exercise path")

I think that this would be easier to understand if we did something like this:

if exerciseSlug == "" && path == "" { return fmt.Errorf... } if path != "" { // get metadata and open the url } // etc

Smarticles101 · 2020-10-22T01:19:46Z

I know it's been nearly two years, but I thought I would get this finished up. I've addressed the last changes requested. If everything looks good I will write some tests.

@ekingery if you'd like to take a look at this and let me know if you see anything that's off, I'd appreciate it :)

Thanks @Smarticles101! We're fully focused on getting configlet updated for V3 right now, but this change looks like something we should be able to get merged as soon as we can bring some focus back to the CLI and get a new version out. It looks like the build is broken at the moment, any ideas on that?

Smarticles101 · 2020-10-23T03:17:00Z

@ekingery yes, like in #957, it fails on older versions of go presumably due to outdated modules. It builds correctly on the latest version

ErikSchierboom · 2024-05-02T10:15:55Z

This is quite an old PR and has some merge conflicts. @Smarticles101 do you still want to work on this?

Smarticles101 · 2024-06-25T21:20:02Z

@ErikSchierboom thanks for checking on this. I've been out of the loop of exercism for a few years and recently started my first full-time job out of college so I don't have much time to pick this up again.

I'll go ahead and close this. If anyone comes across this in the future, feel free to keep working on it :)
