Exercism 8th Track

Exercism exercises in 8th.

CONTRIBUTING

Caution: CI will fail for PRs coming from forked repos

This track uses its own test runner for CI. This requires a secret token to grant access. I'm not sure how this mechanism works, but it means that, for PRs originating from a fork of this repo, access cannot be granted and CI will fail: CI will only pass for PRs merging an exercism/8th branch. Thus only people in the exercism/8th team (i.e. those with write access to this repo) can successfully create a branch, submit a PR, and have CI pass.

Testing

To test the exercises, run ./bin/test. This command will iterate over all exercises and check to see if their exemplar/example implementation passes all the tests.

Track linting

configlet is an Exercism-wide tool for working with tracks. You can download it by running:

$ ./bin/fetch-configlet

Run its lint command to verify if all exercises have all the necessary files and if config files are correct:

$ ./bin/configlet lint

The lint command is under development.
Please re-run this command regularly to see if your track passes the latest linting rules.

Basic linting finished successfully:
- config.json exists and is valid JSON
- config.json has these valid fields:
    language, slug, active, blurb, version, status, online_editor, key_features, tags
- Every concept has the required .md files
- Every concept has a valid links.json file
- Every concept has a valid .meta/config.json file
- Every concept exercise has the required .md files
- Every concept exercise has a valid .meta/config.json file
- Every practice exercise has the required .md files
- Every practice exercise has a valid .meta/config.json file
- Required track docs are present
- Required shared exercise docs are present

Failing test name not printed when stack is not of expected size

When a test fails and the stack is not of the size expected by the tests, the test name is not printed.

E.g., try using this (wrong) implementation for sieve:

: primes \ n -- a
  [1]
;

 []  ... FAIL
    Actual:    « [1]»
    Expected:  «1»

However, changing it to:

: primes \ n -- a
  drop [1]
;

does output the test name:

no primes under two  ... FAIL
    Actual:    « [1]»
    Expected:  « []»

@axtens is this something you can fix?

Building a training set of tags for 8th

Hello lovely maintainers 👋

We've recently added "tags" to student's solutions. These express the constructs, paradigms and techniques that a solution uses. We are going to be using these tags for lots of things including filtering, pointing a student to alternative approaches, and much more.

In order to do this, we've built out a full AST-based tagger in C#, which has allowed us to do things like detect recursion or bit shifting. We've set things up so other tracks can do the same for their languages, but its a lot of work, and we've determined that actually it may be unnecessary. Instead we think that we can use machine learning to achieve tagging with good enough results. We've fine-tuned a model that can determine the correct tags for C# from the examples with a high success rate. It's also doing reasonably well in an untrained state for other languages. We think that with only a few examples per language, we can potentially get some quite good results, and that we can then refine things further as we go.

I released a new video on the Insiders page that talks through this in more detail.

We're going to be adding a fully-fledged UI in the coming weeks that allow maintainers and mentors to tag solutions and create training sets for the neural networks, but to start with, we're hoping you would be willing to manually tag 20 solutions for this track. In this post we'll add 20 comments, each with a student's solution, and the tags our model has generated. Your mission (should you choose to accept it) is to edit the tags on each issue, removing any incorrect ones, and add any that are missing. In order to build one model that performs well across languages, it's best if you stick as closely as possible to the C# tags as you can. Those are listed here. If you want to add extra tags, that's totally fine, but please don't arbitrarily reword existing tags, even if you don't like what Erik's chosen, as it'll just make it less likely that your language gets the correct tags assigned by the neural network.

---

To summarise - there are two paths forward for this issue:

1. You're up for helping: Add a comment saying you're up for helping. Update the tags some time in the next few days. Add a comment when you're done. We'll then add them to our training set and move forward.
2. You not up for helping: No problem! Just please add a comment letting us know :)

If you tell us you're not able/wanting to help or there's no comment added, we'll automatically crowd-source this in a week or so.

Finally, if you have questions or want to discuss things, it would be best done on the forum, so the knowledge can be shared across all maintainers in all tracks.

Thanks for your help! 💙

Possible small documentation change

The instructions that are shown with every exercise include this section (example from hello-world):

From a REPL

Start 8th loading test-words.8th and your solution file: 8th -f test-words.8th -f hello-world-tests.8th This will start a CLI session where you can run tests interactively by copying and pasting them in from hello-world-tests.8th or by entering your own.

Running 8th -f test-words.8th -f hello-world-tests.8th throws an exception on my CLI session because the hello-world word has not been loaded, of course. I presume this ought to be 8th -f test-words.8th -f hello-world.8th and hello-world-tests.8th should not be loaded so that you can follow the instruction later in the paragraph to copy and paste in code from that file.

If my presumption is correct and you agree that this ought to be changed I can bang through all the /exercises/practice/*/.docs/instructions.append.md files and make a PR changing them if that would be helpful. (It would only be a small contribution: I have found the documentation on this track particularly useful.)

Extra space displayed in test output for array values

When a test fails for an array value, the actual and expected value have a leading space that isn't there for other data types:

no primes under two  ... FAIL
    Actual:    « [1]»
    Expected:  « []»

Compared to:

1 is decimal 1  ... FAIL
    Actual:    «1»
    Expected:  «2»

@axtens is this something you can fix?

Actual and expected values are swapped

When a test fails, the actual and expected values are swapped.

E.g., try using this (wrong) implementation for sieve:

: primes \ n -- a
  drop [1]
;

The output is:

    Actual:    « [1]»
    Expected:  «1»

@axtens is this something you can fix?
