@brightspace-ui-labs/input-duration v2.0.0
@brightspace-ui-labs/input-duration
Note: this is a "labs" component. While functional, these tasks are prerequisites to promotion to BrightspaceUI "official" status:
- Design organization buy-in
 - design.d2l entry
 - Architectural sign-off
 - Continuous integration
 - Cross-browser testing
 - Unit tests (if applicable)
 - Accessibility tests
 - Visual diff tests
 - Localization with Serge (if applicable)
 - Demo page
 - README documentation
 
An input component for tracking durations of time. It supports various configurations from weeks to seconds.


Installation
Install from NPM:
npm install @brightspace-ui-labs/input-durationUsage
<script type="module">
    import '@brightspace-ui-labs/input-duration/input-duration.js';
</script>
<d2l-labs-input-duration
    label="Duration"
    units="hours:minutes"
></d2l-labs-input-duration>Properties:
| Property | Type | Description | 
|---|---|---|
label | String, required | Label for the input | 
label-hidden | Boolean | Hides the label visually | 
units | String, required | A colon (:) delimited list of the units to use (ex: hours:minutes). Supported units are weeks days hours minutes seconds. | 
largest-unit-max | Number, default: 99 | Sets the max number for the largest unit of the selected set | 
weeks | Number | Value of weeks for the input | 
days | Number | Value of days for the input | 
hours | Number | Value of hours for the input | 
minutes | Number | Value of minutes for the input | 
seconds | Number | Value of seconds for the input | 
disabled | Boolean | Disables the input | 
error | Boolean | Sets the input into an error state | 
Accessibility:
To make your usage of d2l-labs-input-duration accessible, use the following properties when applicable:
| Attribute | Description | 
|---|---|
label | REQUIRED  Acts as a primary label on the input. Visible unless label-hidden is also used. | 
label-hidden | Use if label should be visually hidden but available for screen reader users | 
Events:
change: Dispatched whenever a value changes for any of the units within the input. The event detail (event.detail) is an object containing the updated values for each unit (ex: an input withweeks:days:hours:minutes:secondsmight have anevent.detaillike this:{ weeks: 2, days: 5, hours: 10, minutes: 30, seconds: 0 }).

This repo uses the @brightspace-ui/visual-diff utility to compare current snapshots against a set of golden snapshots stored in source control.
The golden snapshots in source control must be updated by the visual-diff GitHub Action. If a pull request results in visual differences, a draft pull request with the new goldens will automatically be opened against its branch.
To run the tests locally to help troubleshoot or develop new tests, first install these dependencies:
npm install @brightspace-ui/visual-diff@X mocha@Y puppeteer@Z  --no-saveReplace X, Y and Z with the current versions the action is using.
Then run the tests:
# run visual-diff tests
npx mocha './test/**/*.visual-diff.js' -t 10000
# subset of visual-diff tests:
npx mocha './test/**/*.visual-diff.js' -t 10000 -g some-pattern
# update visual-diff goldens
npx mocha './test/**/*.visual-diff.js' -t 10000 --goldenRunning the demos

npm startVersioning & Releasing
TL;DR: Commits prefixed with
fix:andfeat:will trigger patch and minor releases when merged tomain. Read on for more details...
The sematic-release GitHub Action is called from the release.yml GitHub Action workflow to handle version changes and releasing.
Version Changes
All version changes should obey semantic versioning rules: 1. MAJOR version when you make incompatible API changes, 2. MINOR version when you add functionality in a backwards compatible manner, and 3. PATCH version when you make backwards compatible bug fixes.
The next version number will be determined from the commit messages since the previous release. Our semantic-release configuration uses the Angular convention when analyzing commits:
- Commits which are prefixed with 
fix:orperf:will trigger apatchrelease. Example:fix: validate input before using - Commits which are prefixed with 
feat:will trigger aminorrelease. Example:feat: add toggle() method - To trigger a MAJOR release, include 
BREAKING CHANGE:with a space or two newlines in the footer of the commit message - Other suggested prefixes which will NOT trigger a release: 
build:,ci:,docs:,style:,refactor:andtest:. Example:docs: adding README for new component 
To revert a change, add the revert: prefix to the original commit message. This will cause the reverted change to be omitted from the release notes. Example: revert: fix: validate input before using.
Releases
When a release is triggered, it will:
- Update the version in 
package.json - Tag the commit
 - Create a GitHub release (including release notes)
 - Deploy a new package to NPM
 
Releasing from Maintenance Branches
Occasionally you'll want to backport a feature or bug fix to an older release. semantic-release refers to these as maintenance branches.
Maintenance branch names should be of the form: +([0-9])?(.{+([0-9]),x}).x.
Regular expressions are complicated, but this essentially means branch names should look like:
1.15.xfor patch releases on top of the1.15release (after version1.16exists)2.xfor feature releases on top of the2release (after version3exists)
