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.
Let's stay consistent with previous behavior, and run these on "internal route change" (same component handles different route) as well as on initial render of a page component.
Currently, the controls are on a new line due to the container div. We want to wrap ALL children of the alert, including the controls, in the container div.
We need to split it into a separate class so that we can add modify the alert vnode AFTER the alert component's `view` logic has been applied.
During the frontend rewrite, we introduced mithril patches for a `route` attr, and for `m.stream`. Later, we decided not to go that route, but not to remove the patches yet to avoid breaking extensions while we were finalizing the replacements. We can now remove these.
Other BC layers are for things from before beta 14, so those remain in place.
- Use Mithril.Attributes as base for ComponentAttrs, remove =any from class signature for Component
- Convert Alert to TypeScript, introduce AlertAttrs interface
- Convert AlertManagerState to TypeScript, add overload signatures for `show`, introduce AlertState interface for stored Alerts.
- Set ComponentAttrs as default T for Component
- Make attrs in AlertAttrs optional
- Add AlertIdentifier interface, simplify show type signature
- Remove mithril patch shim, as all patches onto m are now deprecated
- Use Mithril.Static for shim
- Ensure that the discussion list is cleared before it is updated with fetched results
- Rename `clear` to `deferClear`, improve documentation to make its purpose clearer.
- Call onNewRoute when page changed with same component in DiscussionPage and UserPage
- Make app.previous and app.current changed in onNewRoute, not in oninit. This way, when the route is changed, but still handled by the same component, a new PageState object will still be created.
While more pleasant from an FSM standpoint, comparing the current targetPost to the previous one does not work if goToNumber is called twice in a row for the same post. For instance, if a user clicks the mentions link to a post twice, the post stream breaks.
In some cases, such as if we've stickied a post, an event post
may have been added / removed.This means that `this.visibleEnd`
and`this.count()` will be out of sync by 1 post, but we are still
"viewing the end" of the post stream, so we should still reload
all posts up until the last one.
Because the Slidable class was always added on creation, it was lost every time the class list changed (in this case when the discussion was hidden/unhidden which added/removed DiscussionListItem--hidden class). So by determining the Slidable class's presence in elementAttrs() method, it guarantees it always properly set.
While seemingly correct, an onremove method in Modal that triggers animateHide is problematic, because if one modal is opened from another, the one currently open will be removed from the DOM, triggering animateHide, and closing the new modal.
To compensate, an onupdate method now closes a modal if one is open but shouldn't be; this supports the functionality of the old method when the modal is closed not from the modal instance itself (e.g. app.modal.close())
This is not ideal, but necessary. We should consider eventually expanding the modal system to support showing multiple modals at the same time (stacked over each other). Then, we can move this back to individual modals.
When the page is scrolled, goToIndex is called, or the page is loaded,
various listeners result in the scrubber being updated with a new
position and values. However, if goToNumber is called, the scrubber
will not be updated. Accordingly, we add logic to the scrubber's
onupdate to update itself, but only when needed, as indicated by this
This saves us a LOT of unnecessary calls, and makes scrubber movement smoother.
* Update frontend to Mithril 2
- Update Mithril version to v2.0.4
- Add Typescript typings for Mithril
- Rename "props" to "attrs"; "initProps" to "initAttrs"; "m.prop" to "m.stream"; "m.withAttr" to "utils/withAttr".
- Use Mithril 2's new lifecycle hooks
- SubtreeRetainer has been rewritten to be more useful for the new system
- Utils for forcing page re-initializations have been added (force attr in links, setRouteWithForcedRefresh util)
- Other mechanical changes, following the upgrade guide
- Remove some of the custom stuff in our Component base class
- Introduce "fragments" for non-components that control their own DOM
- Remove Mithril patches, introduce a few new ones (route attrs in <a>;
- Redesign AlertManagerState `show` with 3 overloads: `show(children)`, `show(attrs, children)`, `show(componentClass, attrs, children)`
- The `affixedSidebar` util has been replaced with an `AffixedSidebar` component
Challenges:
- `children` and `tag` are now reserved, and can not be used as attr names
- Behavior of links to current page changed in Mithril. If moving to a page that is handled by the same component, the page component WILL NOT be re-initialized by default. Additional code to keep track of the current url is needed (See IndexPage, DiscussionPage, and UserPage for examples)
- Native Promise rejections are shown on console when not handled
- Instances of components can no longer be stored. The state pattern should be used instead.

This is needed to have access to the newly created SuperTextarea
instance (app.composer.editor) directly after calling show().
Discovered when making ext-mentions work with the Composer state
changes. As far as I could reconstruct, a synchronous redraw was also
triggered in this situation before the changes in #2161.
This commit fixes the method `abbreviateNumber` so that it behaves as stated in the JSDoc.
Previously, an input of `1234` would have produced `1K`. With this change, the output will be `1.2K`.
* Fix closing the composer with ESC key
Regression from #2161.
* Remove obsolete method
Regression from #2162.
* Mark method as protected
* Fade in posts in post stream using CSS
This also avoids a double-fade from the JavaScript code, which was
probably introduced in #2160.
* Fix fadeIn for post stream items
