Improves calculations for determining whether we are at the bottom of the notifications panel (which would trigger infinite scroll). This should be particularly effective in fixing issues on smaller screens.
We previously used the tobscure/m.attrs.bidi github repo, but that repo was recently taken offline. We decided to integrate it as a util instead of publishing it as a separate package since we seem to be the only project using it, and adopting it into a new project requires barneycarroll/mattr, which does not seem to be used anywhere.
The code added here was taken from https://github.com/askvortsov1/m.attrs.bidi, a fork (without changes) of the tobscure repo. Support for alternative module systems and ways of registering bidi were removed, and the file was formatted in compliance with our prettier config.
- Anchor scroll when inserting post placeholders
- Indicate that pages are loading at start of `loadPage`, which allows `onscroll` to not request that multiple pages be loaded at the same time
These changes are particularly applicable to firefox, where previously, dozens of posts could be skipped at a time if scroll up was held while at the top of the viewport.
- Support slug drivers for core's sluggable models, easily extends to other models
- Add automated testing for affected single-model API routes
- Fix nickname selection UI
- Serialize slugs as `slug` attribute
- Make min search length a constant
Although native browser scroll restorations have become quite powerful, it interferes with Flarum's PostStream, so if we're on a DiscussionPage, we use manual scroll restoration.
In the PostStream, `this.visibleEnd` represents the index of the last post + 1, but `loadNearIndex` treated it as if it was the index of the last post. This means that executing `goToIndex` on the post stream's current `this.visiblePost` didn't load new posts, and as a result, the requested scrolling did not occur.
This prevents an edge case where `app.discussions` is considered empty while the new page is loading, and as a result, the side pane isn't set as "enabled". Then, if the pane has previously been pinned, when the page loads and the side pane appears, it covers up part of the discussion page.
Fixes https://github.com/flarum/core/issues/2471
- Extensions now have their own pages
- The API for extensions to register permissions and settings has been overhauled via the `flarum/admin/utils/ExtensionData` util
- An extension grid has been added as a widget to the Dashboard page
- Reintroduce cancellable scroll top on page change
- IndexPage: rely on browser to retain scroll position on page reload
- Remove obsolete browser hack
- Fix broken selector
- When on mobile, only retain scroll for IndexPage if we're coming from a discussion
- Move app.cache.scrollTop save into `onbeforeremove` so we make sure to do it before DOM is detached
The default first post number is '1', so we scroll to that if we're calling `m.route.set` without a `near` parameter, as that means we're scrolling to the top.
This was present in beta 13's implementation, but accidentially omitted in 988b6c9.
We also remove unnecessary typecasting for simpler logic and increased consistency with beta 13.
The current implementation for checking whether we are on a discussion page, and going to a discussion page, checks the route we are going to. This is problematic, because the route resolver represents the route being considered, not the route we are currently on. So, if we are currently using a DiscussionPageResolver, we must be going to a route handled by DiscussionPage. Instead, we need to check the route that we are currently on, which is done via `app.current.matches(DiscussionPage)`.
- mapRoutes: don't wrap components in resolvers if they are already resolvers
- Extract defaultResolver into its own class
- Allow either route resolver instances, or components with an optional resolverClass which should accept the component and route name in its constructor.
- Introduce a resolver for DiscussionPage, so that routing from one post to another on the same discussion triggers a scroll instead of rerendering
- Add an index to reply placeholder so we can scroll to it directly when replying.
- Stop pretending that the currently broken `bottom` scroll functionality works, and explicitly call it `reply` scrolling to be clearer
- Directly get target from state
- Explicitly scroll to placeholder on reply
- Clean up scrollToItem code a bit
- Account for edge case where index is undefined when scrolling to post

Essentially, whenever a route is loaded, we add a key to that component. If the key changes, the page completely rerenders. Switching between different routes handled by the same key triggers those rerenders.
- If the fadeIn animation is specified on the PostStream class itself, any time we add/remove another animation, it will redo fadeIn. To avoid this, we move fadeIn into it's own css class, which is applied, and then immediately removed after the animation is completed to ensure it only runs once.
- The "fix" for flashItem was actually broken, as it resulted in 'flash' never being removed, so we never went back to .PostStream's fadeIn. We adjust flashItem to ensure that '.flash' is removed. We also remove 'fadeIn' in case it hasn't yet been removed in oncreate.
Make header and navigation components redraw after page components. Page components manipulate the header (state), but the header redraws before the page on route change. By changing the mount order, we change also the redraw order.
If the error isn't a 409, we'll want to re-throw the error so it'll be handled by the default system (showing an alert).
For simplicity, we can also move 409-handling logic out of setTimeout.
Finally, we adjust the timeout to 300 milliseconds to match the modal transition animation length.
* Revert "Fix header contents moving when opening modal (#2131)"
* Fix header contents moving when modal opened/closed.
Conditionally apply the navbar-fixed-top class only when needed, so that we can take advantage of it without always having the navbar in position:fixed, as was done in the previous solution. That resulted in a clash with custom headers.
* Show header on refresh of scrolled page
Due to some magic in Mithril 0.1's context:retain flag, some DOM elements were cached across page reloads. Since that has been eliminated, if we refresh the page and we are scrolled down, the "affix" class which makes the header fixed (and as a result, visible) isn't applied until the first scroll. We fix this by running ScrollListener.update() immediately to set initial navbar state.
When on a discussion page, the URL changing doesn't always mean we've moved to a different page. In our custom rerender logic, we only want to call `this.onNewRoute()` if the page has actually changed.
After we scroll to a post, we redraw to render post content. We then update the scrubber again so its height is accurate. This commit moves that update to AFTER our adjustment of scroll position, so that scrubber height is based on actual post heights. This fixes some subtle scrubber glitches.
