sciolyff-js

Test Status Coverage Status npm

sciolyff-js is a JS port of SciolyFF, a standardized file format to represent Science Olympiad tournament results. SciolyFF is a subset of YAML.

SciolyFF powers Duosmium Results, a tournament results archive/viewer.

Installation

npm install sciolyff

Usage

The default entrypoint exports a Interpreter class and a valid() function.

Validation

async function valid(
  repOrYaml: string | Record<string, unknown>,
  options: { abortEarly?: boolean; canonical?: boolean } = {}
): Promise<{
  valid: boolean;
  success: boolean;
  validWithWarnings: boolean;
  status: string;
  errors?: Error[];
}>;

Arguments:

  • repOrYaml: a string or object representing a sciolyff representation
  • options:
    • abortEarly (default: false): abort validation on first error
    • canonical (default: true): throw warnings on non-canonical school/event names

Returns:

  • valid: is sciolyff valid?
  • success: was validation successful?
  • validWithWarnings: are there warnings (if valid)?
  • status: human readable status messages
  • errors?: validation errors (if any)

To parse the returned errors list, we provide a sciolyff.format function.

function format(errors?: Error[], filename?: string, colors?: boolean): string;

Arguments:

  • errors: the errors property returned by sciolyff.valid
  • filename: the original filename (used for line numbers/linking)
  • colors: whether to color the output (recommended if you're outputting to a terminal)

Returns:

The formatted error messages (string).

The sciolyff-js package also has a command line utility that can validate if a given file meets the spec.

$ npx sciolyff-js -h
Usage: npx sciolyff-js [options] <file>

Arguments:
  file               file to check

Options:
  -n, --no-canon     Disable canonical name checks.
  -a, --abort-early  Abort on first error.
  -h, --help         display help for command

Parsing

The Interpreter class can be used to parse SciolyFF. Validation is not performed, so make sure you're passing in valid SciolyFF (which you can validate with valid()).

import fs from "fs";
import sciolyff from "sciolyff";

const file = fs.readFileSync("2022-01-08_national_invitational_c.yaml", "utf8");
const interpreter = new sciolyff.Interpreter(file);

let anat = interpreter.events.find((e) => e.name === "Anatomy and Physiology");
console.log(anat.trialed); // false

let team_one = interpreter.teams.find((t) => t.number == 1);
console.log(team_one.placingFor(anat).points); // 62
console.log(team_one.points); // 1090
console.log(team_one.school); // Adlai E. Stevenson High School
console.log(team_one.suffix); // Gold

// sorted by rank
console.log(interpreter.teams.slice(0, 3));
// [ { school: 'Mountain View High School', suffix: 'Black', number: 87, state: 'CA' ... }, ... ]

Development

Install dependencies with npm install. Build the project with npm run build. The dist directory contains the built files.

To publish the package to NPM, use npm run release. This will run tests, build the package, and publish it to NPM.

Testing

Tests run automatically before releasing (with npm run release), as well as with GitHub Actions on push. You can manually run tests using npm test.

We use AVA as a test runner, and most of our tests are snapshot tests. However, since our snapshots are quite large and AVA displays the full file, it may be difficult to find differences when they occur. If you find a difference, you can use npm run update-snapshots to update the snapshot, then inspect the output with git diff tests/interpreter/snapshots/test.ts.md (or the appropriate path for validator snapshots). After inspecting the snapshot diff and verifying that everything is expected, commit the snapshot files.

Legacy Tests

Note: We have updated our tests, so this information is here for reference only.

To ensure that the output of this package matches the output of the previous Ruby-based package, we have a couple of testing scripts to run.

First, ensure that Ruby is installed (versions between 2.7 and 2.5). You may want to use asdf to manage your Ruby versions.

Next, install the sciolyff-duosmium gem by cloning the sciolyff-ruby repo.

git clone https://github.com/Duosmium/sciolyff-ruby.git
cd sciolyff-ruby
gem build sciolyff.gemspec
gem install sciolyff-duosmium-0.13.1.gem

You will also need to install psych 3.3.2.

gem install psych -v 3.3.2

Get the latest data files by cloning the duosmium repository in the same parent folder as this current repository (sciolyff). The duosmium- directory should be accessible from this current directory by moving one layer up (../duosmium).

git clone https://github.com/Duosmium/duosmium.git

You are now ready to generate the test files. Create new directories to place the generated json files.

mkdir compare/js
mkdir compare/ruby

To generate files:

node compare/generateJs.js
ruby compare/generateRuby.rb

When running the Ruby script, you may see the following error:

sciolyff-duosmium-0.13.1/lib/sciolyff/interpreter.rb:20:in `initialize': uninitialized constant SciolyFF::Interpreter::Psych (NameError)

If this occurs, you'll need to manually patch the interpreter.rb file. Navigate to the full path displayed in the error message and add the following lines to the file:

  # ...
  require 'sciolyff/interpreter/track'

+ require 'psych'
+ require 'date'

  attr_reader :tournament, :events, :teams, :placings, :penalties, :tracks

  def initialize(rep)
      if rep.instance_of? String
  # ...

After the test files have been generated, run the following script to compare results:

node compare/compare.js

Any files containing differences will be printed to the console. If such files exist, you'll need to manually inspect them. Use a service like Diffchecker to compare the two files and find where exactly they differ.
