- adds "Email" card to the card menus when developer experiments is turned on
- adds `<KoenigTextReplacementHtmlInput>` implementing most of Koenig except:
- uses html as it's input/output format
- replaces backtick "code" formatting with `{replacement}`
- no headings
- no cards at all
- minimal toolbar but all formatting is still available using markdown text expansions or keyboard shortcuts
no issue
- the card wrapper component was registering an event handler for keyboard events when entering edit mode. This was a problem because those events were also picking up the initial ctrl/cmd+enter and then immediately toggling back out of edit mode
- added a 20ms timeout for registering the event handlers so that they're not working cross-purposes
no issue
- when the mobiledoc spec changes due to a mobiledoc-kit version bump, any posts created with that version will fail to load in the editor if a rollback to an earlier Ghost version occurs
- use an explicit version to avoid the problem - we should only be bumping the mobiledoc spec version if we start using features from that version and mark it as a breaking change
closes https://github.com/TryGhost/Ghost/issues/10240
- intercept known macOS content-modifying keyboard shortcuts and simulate the "normal" keyboard events that they map to
- `ctrl+h`: `Backspace`
- `ctrl+d`: `Delete`
closes https://github.com/TryGhost/Ghost/issues/10090
- when mobiledoc-kit replaces the selection the caret window selection is temporarily set to the whole editor element which was causing our scroll-cursor-into-view routine to scroll incorrectly
- adding the guard allows the first replacement cursor change to be ignored but the second cursor change to be picked up which will do nothing if the text is on-screen, or scroll if it's off screen as normal
closes https://github.com/TryGhost/Ghost/issues/9792
- use `getClientRects()` to get separate rectangles for each line of a link and use the mouse position to find the closest one so that the toolbar can be positioned relative to that link section on that line rather than always in the middle of the editor canvas
- pass the rectangle used for positioning the link toolbar through to the link input component so that there is no jumping of position when clicking the edit button
no issue
- removes number of clicks required to insert images, especially when using the `/image` shortcut
- strips `triggerBrowse` property from the payload after inserting to avoid triggering file browse when a post with blank image cards is rendered/re-rendered
no issue
- the `willDestroyElement` hook is referencing event handlers that aren't used in the bookmark card
- stopped setting `type` in the card payload as it's not used anywhere (possible hangover from when bookmarks were a type of embed card)

Ember is migrating to `<AngleBracketSyntax />` for component invocation, see https://github.com/emberjs/rfcs/blob/master/text/0311-angle-bracket-invocation.md
We were in a half-way situation where some templates used angle bracket syntax in some places, this PR updates templates to use the syntax everywhere.
This simplifies the rules for what template code is referring to...
`<Component>` = a component
`{{helper}}` = a helper (or locally assigned handlebars variable)
`{{this.foo}}` = data on the template backing context (a component/controller)
`{{@foo}}` = a named argument passed into the component that the component backing class has not modified (note: this commit does not introduce any named arguments)
- ran codemod https://github.com/ember-codemods/ember-angle-brackets-codemod on the following directories:
- `app/templates`
- `lib/koenig-editor/addon/templates`
- removed positional params from components as angle bracket syntax does not support them
- `gh-feature-flag`
- `gh-tour-item`
- `gh-cm-editor`
- `gh-fullscreen-modal`
- `gh-task-button`
- updates some code that was missed in 3c851293c1 to use explicit this
no issue
- convert relative links to absolute based on the configured blog url when displaying URLs in the link toolbar and when manually setting a relative link
- converting to absolute in the editor prevents the in-memory mobiledoc getting out of sync with the server response when it converts relative urls to absolute
requires https://github.com/TryGhost/Ghost/pull/11024
With the bookmark card you can present links in a much richer format, similar to Twitter cards. If the URL points to a page with right meta information it can show the page title, excerpt, author, publisher and even a preview image.
Bookmark cards can be created in two ways:
1. pasting a link as the first thing in blank paragraph - we'll check to see if we can create an embed, if we can't then we'll create a bookmark card instead
2. manually selecting the bookmark card from the (+) menu or by typing "/bookmark<kbd>Enter</kbd>" or "/bookmark {url}<kbd>Enter</kbd>" for short (you might want to do this if you want the bookmark version instead of a full embed)
Pressing <kbd>Ctrl/Cmd+Z</kbd> after pasting will convert the bookmark card back to a link if that's preferred, alternatively a URL can be pasted with <kbd>Ctrl/Cmd+Shift+V</kbd> to avoid any automatic transformation to an embed/bookmark.
---
- adds "bookmark" card that functions similarly to the embed card
- if the oembed API request returns `type: "bookmark"` then the metadata is used to create a bookmark card
no issue
- adds an "Alt" button that is displayed in the caption input whilst an image card is selected, clicking it toggles between the rich-text caption input and a plain-text alt text input
no issue
- adjust drag handlers in the editor and gallery card to handle drag/drop of image cards as well as straight images
- adjust drag handlers in the gallery card to handle image inserts as well as re-orders
- add `onDragEnd` event/action to the Koenig drag-n-drop handler so that containers can perform cleanup if one of their draggables was successfully dropped into a different container
- change ghost element when dragging an image card to be an image rather than a card icon
- allow `createGhostElement` function passed in when registering a drag-n-drop container to fall back to the default behaviour by returning a falsy value

- `@tryghost/kg-parser-plugins` contains the parser plugins used by the editor and was extracted so that they can be used in server-side html-to-mobiledoc conversion
no issue
- `cleanBasicHtml` has been extracted to an external package so that it can be used inside the extracted `@tryghost/kg-parser-plugins` package server-side
no issue
- Added a language indicator when in rendered mode and a language input when in edit mode
- Allow code card language to be set with <code>```lang</code>+<kbd>Space/Enter</kbd> expansion
- previously <code>\`\`\`</code> would immediately create a code card, the <kbd>Space/Enter</kbd> is now necessary for the insertion to occur
- lang is optional <code>\`\`\`</code>+<kbd>Space/Enter</kbd> will insert a code card with no language selected
- requires <kbd>Enter</kbd> to be pressed to finalise the expansion and insert the card
- added hook for text expansions to skip newline creation for when they are triggered with <kbd>Enter</kbd>
- Set the code card editor's language mode based on selected language
- set the CodeMirror mode based on the code card payload language
- add a basic map of language short codes to their respective CodeMirror modes
- observe `mode` property in `{{gh-cm-editor}}` so that the mode is properly set when it's changed after initial render
closes https://github.com/TryGhost/Ghost/issues/9847
- the text expansion is triggered twice in this situation, the first time with `""` and the second with `"/"`. The second trigger was trying to match cards to `"/"` which returned an empty card set
- added a quick workaround that ensures we never include a leading `/` in the card selection query
closes https://github.com/TryGhost/Ghost/issues/10677
- adjusted the basic markdown text expansion behaviour to delete the MD chars and add a markup to the resulting range rather than deleting the whole range and re-adding it
- extracted basic markdown format behaviour into a helper function
- fixed the link markup expansion so that `[](https://example.com)` is recognised and creates a link with the URL as the text
no issue
- `**bold**` would sometimes result in any further typing keeping bold formatting
- switching to a fixed number of milliseconds helps with timing so mobiledoc-kit does not reset the internal format state _after_ the actions queue had already run
no issue
- added `page` model
- removed `page` param from Post model
- added pages screen with associated links
- added `:type` param to editor screens to work with the right models
- removed post<->page toggle and associated tour item
closes https://github.com/TryGhost/Ghost/issues/10399
- added a data attribute `data-koenig-dnd-disabled` which will prevent the element or any of it's children from initiating a koenig drag event
- applied the data attribute to `{{koenig-basic-html-input}}`'s outer tag so that captions never initiate a card re-order
- disabled card re-ordering when a card is in edit mode
- allows text selection within a markdown/html card without triggering the card re-order behaviour
- clicking another card will exit edit mode and re-enable drag before the drag behaviour is initiated so you can still re-order other cards if you've left a card in edit mode
no issue
- the polyfill is no longer required for latest browsers (tested on Chrome, FF, and Safari)
- Edge may have problems but it's not currently supported

- use [`chai-dom`](https://github.com/nathanboktae/chai-dom) assertions where in some places (still a lot of places in the tests that could use these)
- pin `ember-in-viewport` to 3.0.x to work around incompatibilities between different versions used in `ember-light-table`, `ember-infinity`, and `ember-sticky-element`
- incompatibilities manifested as "Invalid value used as weak map key" errors thrown when using `ember-light-table` (subscribers screen)
- pin `ember-power-datepicker` to unreleased version that contains a move from global acceptance test helpers to modern test helpers
no issue
- add vertical drop position indicator handling to `koenig-drag-drop-handler` service
- fixed issues with nested drag-and-drop containers
- register card drag/drop handler in `koenig-editor`
- add drag icon creation
no issue
Adds auto-scroll if the mouse is placed near the top or bottom of the window whilst dragging an image to re-order it within a gallery. Useful when the position you want to drag to is not currently on screen.
- append drop indicator element to `.koenig-editor` element to account for scrolling (also fixes indicator positioning bug with current implementation if you use mouse-wheel or keyboard to scroll the page whilst dragging)
- generalise `getParent` util to accept a
- switch to using selectors rather than dataset for finding parent draggable/droppable/container
- add a `ScrollHandler` class that is used by the `koenigDragDropHandler` service to trigger scrolling whilst dragging
no issue
- https://github.com/TryGhost/Ghost-Admin/pull/1081 introduced a bug where the `insertIndex` was being cleared every time we showed the drop position indicator because we hide the indicator as a reset every time we show the indicator. This meant every drop was missing the required insertIndex.
- added a flag to the `_hideDropIndicator` function so that a reset when showing the indicator doesn't clear the required information
no issue
- clear the cached `insertIndex` when hiding the drop position indicator
- update the gallery card's `_isDropAllowed` function to return `false` if the `droppabeIndex` (`insertIndex`) doesn't exist
no issue
- when dragging an image, if you dragged out of the gallery then back in directly over the space between images then no indicator was shown
- switch to using padding around images rather than margin so that the mouse can be detected over the gap. Added classes to the image overlays to account for the change in sizing
no issue
- first pass at implementation of drag-and-drop re-ordering of images within a gallery
- adds a `koenig-drag-drop-handler` service that allows consumers (editor and cards) to hook into drag and drop behaviour without interfering with each other and allows for future possibilities such as dragging images between galleries or into/out of galleries
no issue
- use `URL.createObjectURL(file)` to get a blob url rather than using `FileReader.readAsDataURL` which generates a very large data attribute
- speeds up the display of previews and associated browser hangs when an upload finishes, especially noticeable with large images and fast connections where multiple uploads finish around the same time
closes https://github.com/TryGhost/Ghost/issues/9840
- added error on uploading an invalid image format
- updated to use overall error method(`onFailed`) to set error message instead of individual upload failures(`onUploadFailure`)

- update `{{koenig-card}}` component to compare payload values and create a snapshot when exiting edit mode for container cards (markdown, html, code)
- update image card to trigger snapshots on image upload/selection and width change
no issue
- we were throttling word count updates but not taking into consideration the editor components could have been destroyed by the time the throttle timeout occurred
closes https://github.com/TryGhost/Ghost/issues/9852
- Ember was throwing an error because we weren't using `.set` to set properties on the editor component which halted execution whilst the component cards were being re-rendered
closes https://github.com/TryGhost/Ghost/issues/9825
- the <code>`</code> key on German keyboard layouts is a dead key and so does not trigger the typical keyboard events our editor relies on
- added custom keyboard event listeners to watch for specific keyboard event sequences triggered by using the dead key + spacebar to insert a <code>`</code>
- trigger text input handlers when we detect a <code>`</code> insertion
- Linux unfortunately does not trigger events that can be used to track the sequence so this will not work there although it is easier to set up keyboard layouts without dead keys on Linux
- moved modifier key tracking into global event handlers from ember event handlers
- reduce confusion from duplicated event handling
- allows modifier key handlers to fire when keys are pressed without the editor element having focus
no issue
- added `onUploadStart` action to `{{gh-uploader}}` that is triggered when individual files start uploading
- will not be triggered for any files that fail client-side validation
- changed `{{koenig-card-gallery}}` to only add images to the local gallery display when the uploader starts an upload
no issue
- moved all payload building into single function
- only put fully valid images into mobiledoc
- extracted image data reading and width/height reading into a separate function
- fixed re-ordering when deleting an image

- the "paste url on a selection to make it a link" feature from the main editor was missing in caption inputs
- copied functionality across (shared functionality needs extracting at some point)

- `clean-basic-html` was being overzealous with it's empty element removal, often contenteditable (especially when pasting) will result in HTML such as `<span> </span>` which was being completely removed
- if an empty element has any spaces in it, replace the element with a textNode containing a single space
refs https://github.com/TryGhost/Ghost/issues/9724
- focus was not being returned to the editor after the Unsplash modal was closed so although the image card looked selected the editor was not responding to any key commands
refs https://github.com/TryGhost/Ghost/issues/9724
- mobiledoc-kit's `key.isPrintable()` returns true for <kbd>Enter</kbd> but in this instance we don't want to capture newlines as printable chars
- swapped insertion of `event.key` for `key.toString()` for better handling of named keys that output characters (eg. when `event.key` === `Enter` which prints `\n`)
refs https://github.com/TryGhost/Ghost/issues/9724
- we call `koenig.cleanup` when setting a post in the editor controller but the call will happen before `componentCards` has been populated so none of our "delete if empty" routines were being run
- calls to `.cleanup` now schedule the cleanup after the next editor render which should mean cards are populated before we try to remove them
refs https://github.com/TryGhost/Ghost/issues/9724
- standardised `{{gh-unsplash}}` actions and action arguments to better represent a generic "image source"
- added `{{gh-unsplash searchTerm="ghosts"}}` parameter
- added `payload` param to `card` definitions used for plus/slash menus so that default payload params can be passed to cards
- added a concept of "image selectors" to image card
- if a `payload.imageSelector` param is received by the card it will look it up in it's list of known selectors and display the appropriate image selection component
- if the card was created with an image selector param and the image selector is closed without selecting an image then the card will be removed
- delete image cards during cleanup if they were created via selector but have no src

- extract html sanitisation into a Koenig helper `{{sanitise-html}}` (all markdown handling will eventually move into Koenig too)
- render sanitised html in the html card
no issue
- re-org of the text-expansions code meant that the smart hyphens expansion was being picked up before the divider card expansion and blocking it
refs https://github.com/TryGhost/Ghost/issues/9724
- add a `data-kg-allow-clickthrough` attribute so that it's possible to explicitly allow non-input elements to be clicked immediately when clicking on a card
refs https://github.com/TryGhost/Ghost/issues/9724
- added `{{koenig-basic-html-input}}` component
- uses a stripped down version of Koenig
- supports all inline formatting that Koenig supports
- supports inline text expansions
- supports inline key commands
- limited to a single paragraph
- serialises and deserialises from HTML rather than mobiledoc
- updated `{{koenig-caption-input}}` to use `{{koenig-basic-html-input}}`
- updated image and embed cards to calculate word counts correctly for html captions
- bumped Spirit dependency to fix styling of toolbars within the editor canvas
- fixed positioning in toolbar components to account for `parentElement` not necessarily being the closest element to position against
refs https://github.com/TryGhost/Ghost/issues/9724
- selecting the embed card as soon as it's created causes problems with the caption input grabbing focus which interferes with being able to continue typing
- if content exists after the paste move the cursor to the beginning of the next section, otherwise create a blank paragraph and move the cursor into that
refs https://github.com/TryGhost/Ghost/issues/9724
- if a URL is pasted in a blank paragraph, insert an embed card configured to switch immediately to a link if the embed fails
- if <kbd>Shift</kbd> is pressed when pasting insert a linked URL with no auto-embed
- added `payload.linkOnError` handling to the embed card
- if that option is set, immediately convert the embed card section to a linked URL on embed failure
- skip adding an undo step when auto-converting to a URL so that no undo loop is created. Without this an undo would convert from link to embed card which would automatically look up the url then convert back to a link meaning it's impossible to undo back past the URL paste
- ensure that the cursor position doesn't jump if the user has continued writing whilst the oembed lookup is in progress
refs https://github.com/TryGhost/Ghost/issues/9724
- `card.handlesDragDrop` was never accessible, it would have had to be registered through `card.koenigOptions.handlesDragDrop` when the drop handling was first added
- as of cc2e20a486 properties on card components are directly accessible so we can use `card.component.handlesDragDrop` to guard against the editor handling drops on cards that handle their own drops
refs https://github.com/TryGhost/Ghost/issues/9724
- adjust `insertImageCards()` to handle the editor not having an active section

- `event.code` represents physical key location rather than the associated key value. Eg, `event.code` could be `NumpadEnter` rather than the expected `Enter` value
- ensure we use `event.key` anywhere that we are acting on the key value so that re-mapped or virtual keys still work as expected
refs https://github.com/TryGhost/Ghost/issues/9724
- leaving the editor could result in the plus menu being removed from DOM before teardown has fully cleared up the event handlers resulting in an error being thrown in the mousemove handler where we assumed the element is present

- add `registerComponent` hook to cards so that `{{koenig-editor}}` can fetch properties from card components directly
- add word count and reading time utilities
- add throttled word count update routine to `{{koenig-editor}}` that walks all sections and counts text words or fetches word/image counts from card components
- add `wordCountDidChange` hook to `{{koenig-editor}}` so that word count + reading time can be exposed

- add guard to check for `event` presence before attempting to stop propagation
refs https://github.com/TryGhost/Ghost/issues/9724
- the click event from clicking on the /-menu items continued propagating after the card was initialised which meant it was picked up by the card as a "click off the card" so certain cards such as the Markdown/HTML cards would then remove themselves as if they were deselected with empty content
- changed the icon click handler to use the DOM `onclick` syntax so that the click can be captured immediately rather than waiting for it to bubble up to Ember's global event handler
- updated the /-menu `itemClicked` action to use the now-accessible MouseEvent to stop it propagating any further and triggering unwanted card behaviour
refs https://github.com/TryGhost/Ghost/issues/9724
- `element.contains(target)` was not reliably picking up the `<span>` inside the `<button>` element
- added a fallback that searches the event path for the card component's ID

- `{{koenig-menu-content}}` does not pass any params through when an item is clicked
- move the `params` fetching via the query string from `_performAction()` to `actions.itemClicked` so that it works for both <kbd>Enter</kbd> and icon clicks
refs https://github.com/TryGhost/Ghost/issues/9724
- if the editor was reloaded by changing the post model either through clicking "New story" or using the search from the editor screen the /-menu would stop working
