New range tag for local dates with syntax like:
```
[date-range from=2022-01-06T13:00 to=2022-01-08 timezone=Australia/Sydney]
```
Previously, 2 dates in one line were considered as range. It was hard to decide if 2 dates are range when they were in separate lines or have some content between them.
New explicit tag should clearly distinguish between single date and range.
Common code from `addLocalDate` is extracted to `addSingleLocalDate`.
Both `addLocalDate` and new `addLocalRange` are using `addSingleLocalDate`.
Also, `defaultDateConfig` was extracted to have one place for all possible parameters.
* FIX: do not display add to calendar for past dates
There is no value in saving past dates into calendar
* FIX: remove postId and move ICS to frontend
PostId is not necessary and will make the solution more generic for dates which doesn't belong to a specific post.
Also, ICS file can be generated in JavaScript to avoid calling backend.
- Stop looking up the topic title from the DOM. On long topics, the topic title may not be present. Instead, we can store the topic title in a data-title attribute during decorateCookedElement, and then access it later. This approach would also allow us to add customize titles per-local-date in future. If there is no topic title available (e.g. when local dates are used elsewhere in the UI), we use the site name to build a sensible default
- Don't require a postId for creating calendar events. We don't have postIds in non-post contexts. At the moment, the 'download ICS' function will fail without a valid postId, so that will need to be fixed in a future commit.
When there is a blank space in the end of date, moment is returning a different value:
```javascript
console.log(moment.tz("2021-09-09 ", "Australia/Sydney").toISOString());
// 2021-09-09T00:00:00.000Z
console.log(moment.tz("2021-09-09", "Australia/Sydney").toISOString());
// 2021-09-08T14:00:00.000Z
```
It allows saving local date to calendar.
Modal is giving option to pick between ics and google. User choice can be remembered as a default for the next actions.
When start/end was missing the time component the string passed to `moment()` would have a space at the end. This was causing these warnings:
```
Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.
```
If parent element for range does not exists, range calculator should
return empty array. In that case duration calculations will stop because
of:
```
if (_rangeElements(element).length === 2) {
opts.duration = _calculateDuration(element);
}
```
This PR is introducing 2 changes.
1. Date popup is displayed on click instead on hover
2. If the range is given then the whole range is always displayed for both startDate and endDate
3. For range, short time is displayed for end if the range is < 24 hours
This adds a new property, `pluginId` which you can pass to `modifyClass`
which prevent the class from being modified over and over again.
This also includes a fix for polls which was leaking state between tests
which this new functionality exposed.
- prefers insertAdjacentHTML over innerHTML as it's much faster in this case (about 5x)
- memoizes tz.guess()
- memoizes list of timezones
- inlines template
- applies main element class in one pass
All in all for a very edge case of about 80 dates it should be faster of about 15/20ms.
* Remove long-deprecated method
* FIX: Memory Leaks when decorating posts
Previously we'd keep creating mixins dynamically when decorating the
same class.
This code changes the API to recommend an `id` parameter for each
decorator which will avoid leaks. All plugins should be updated to
include this parameter, although if they don't in the meantime it'll
just mean a warning in the console (and a continued leak.)
