### How to use the library

#### Install the package

Using NPM

```
npm install @openbeta/sandbag
```
Using Yarn
```
yarn add @openbeta/sandbag
```

#### Sample Usage

- Convert Grades to Scores

```javascript
import { French, YosemiteDecimal } from '@openbeta/sandbag'

const score = French.getScore('8a') // Output [ 84, 85 ]

// Support slash grade
const slashGradeScore=French.getScore('7c+/8a') // Output [ 83, 84 ]

// Accept +/- modifier
const plusGrade= YosemiteDecimal.getScore('5.12+') // Output [ 79, 80 ]
```

- Convert Scores to Grades

```javascript
import { Font } from '@openbeta/sandbag'

// Single score provided
Font.getGrade(80) // Output '7c'

// Support a range of scores 
Font.getGrade([79,81]) // Output'7b+/7c'

```

- Validate Grading Scales
``` javascript
import { VScale , Font }from '@openbeta/sandbag'

console.log('Is 6A a V Scale?',VScale.isType('6A'))  // Output false
console.log('Is 6A a Font Scale?',Font.isType('6A')) // Output true

```

- Convert Grades Across Scales

``` javascript
import {convertGrade , GradeScales }from '@openbeta/sandbag'

const ydsInFrench=convertGrade('5.11a',GradeScales.YDS,GradeScales.FRENCH) // Output '6b+/6c'

const fontInVScale=convertGrade('6a',GradeScales.FONT,GradeScales.VSCALE) //OutPut 'V3'

// Conversions across different disciplines are not allowed
const sportToBoulder=convertGrade('5.11a',GradeScales.YDS,GradeScales.VSCALE)
// Output: Scale: Yosemite Decimal System doesn't support converting to Scale: V Scale
// ''
```

- Get Gradeband

```javascript
import { Ewbank } from '@openbeta/sandbag'

Ewbank.getGradeBand('10') // Output: 'beginner'
Ewbank.getGradeBand('30') // Output: 'expert'
Ewbank.getGradeBand('6a') // Output: Unexpected grade format: 6a for grade scale Ewbank 'unknown'

```
- Compare Grades

```javascript

import { French, YosemiteDecimal } from '@openbeta/sandbag'

const harder = French.getScore('8a')  // Output: [ 84, 85 ]
const easier = YosemiteDecimal.getScore('5.13a') // Output: [ 82, 83 ]

console.log('Is 8a harder than 5.13a?',harder > easier) // Output: true

```

See [unit tests](./src/__tests__) for more examples.

### Development (TBD)

```
yarn install
yarn test
```

#### Generating Test Coverage Report

To generate a test coverage report using Jest run the following command in your terminal:

```sh
npx jest --coverage
```

If you're using macOS, you can directly access the coverage report in your browser by opening the following URL:

```
file:///Users/<userName>/sandbag/coverage/lcov-report/index.html
```

#### How to publish a new release to NPM
Submit a PR with commit message `[npm publish]`
