Added

• Adds addCommunitySectionLink which allows plugins to add a navigation link to the Sidebar community section under the "More..." links drawer.

• Adds registerUserCategorySectionLinkCountable which allows plugins to register a new countable for section links under Sidebar Categories section on top of the default countables of unread topics count and new topics count.

• Adds registerCustomCategorySectionLinkLockIcon which allows plugins to change the lock icon used for a sidebar category section link to indicate that a category is read restricted.

• Adds registerCustomTagSectionLinkPrefixValue which allows plugins to register a custom prefix for a sidebar tag section link.

• Adds refreshUserSidebarCategoriesSectionCounts which allows plugins to trigger a refresh of the counts for all category section links under the categories section for a logged in user.

• Adds addSidebarSection which allows plugins to add a Sidebar section.

• Adds registerNotificationTypeRenderer which allows plugins to register a custom renderer for a notification type or override the renderer of an existing type. See lib/notification-types/base.js for documentation and the default renderer.

• Adds registerModelTransformer which allows plugins to apply transformation using a callback on a list of model instances of a specific type. Currently, this API only works on lists rendered in the user menu such as notifications, bookmarks and topics (i.e. messages), but it may be extended to other lists in other parts of the app.

• Adds addUserMessagesNavigationDropdownRow which allows plugins to add a row to the dropdown used on the userPrivateMessages route used to navigate between the different user messages pages.

[1.6.0] - 2022-12-13

[1.5.0] - 2022-11-21

Added

• Adds addComposerSaveErrorCallback, which allows users to register custom error handling for server-side errors when submitting on the composer.

[1.4.0] - 2022-09-27

Added

• Adds registerHighlightJSPlugin, which allows users to register custom HighlightJS plugins. See https://highlightjs.readthedocs.io/en/latest/plugin-api.html for documentation.

[1.3.0] - 2022-05-29

Added

• N/A - Mistakenly bumped.

[1.2.0] - 2022-03-18

Added

• Adds registerCustomLastUnreadUrlCallback, which allows users to register a custom function that returns a last unread url for a topic list item. When multiple callbacks are registered, the first non-null value that is returned will be used.

[1.1.0] - 2021-12-15

Added

• Adds addPosterIcons, which allows users to add multiple icons to a poster. The addition of this function also makes the existing addPosterIcon now an alias to this function. Users may now just use addPosterIcons for both one or many icons. This function allows users to now return many icons depending on an attrs.

[1.0.0] - 2021-11-25

Removed

• Removes the addComposerUploadProcessor function, which is no longer used in favour of addComposerUploadPreProcessor. The former was used to add preprocessors for client side uploads via jQuery file uploader (described at https://github.com/blueimp/jQuery-File-Upload/wiki/Options#file-processing-options). The new addComposerUploadPreProcessor adds preprocessors for client side uploads in the form of an Uppy plugin. See https://uppy.io/docs/writing-plugins/ for the Uppy documentation, but other examples of preprocessors in core can be found in the UppyMediaOptimization and UppyChecksum classes. This has been done because of the overarching move towards Uppy in the Discourse codebase rather than jQuery fileupload, which will eventually be removed altogether as a broader effort to remove jQuery from the codebase.

Changed

• Changes addComposerUploadHandler's behaviour. Instead of being only usable for single files at a time, now multiple files are sent to the upload handler at once. These multiple files are sent based on the groups in which they are added (e.g. multiple files selected from the system upload dialog, or multiple files dropped in to the composer). Files will be sent in buckets to the handlers they match.
