See: https://meta.discourse.org/t/bundling-more-popular-plugins-with-discourse-core/373574 Adds the ability to create a dynamic calendar in the first post of a topic. Topic discussing the plugin itself can be found here: [https://meta.discourse.org/t/discourse-calendar/97376](https://meta.discourse.org/t/discourse-calendar/97376) ## Customization ### Events - `discourse_post_event_event_will_start` this DiscourseEvent will be triggered one hour before an event starts - `discourse_post_event_event_started` this DiscourseEvent will be triggered when an event starts - `discourse_post_event_event_ended` this DiscourseEvent will be triggered when an event ends ### Custom Fields Custom fields can be set in plugin settings. Once added a new form will appear on event UI. These custom fields are available when a plugin event is triggered. ### Holidays See an incorrect or missing holiday? Familiarize yourself with the [holiday definition Syntax](vendor/holidays/definitions/doc/SYNTAX.md). Then make your updates in the `vendor/holiday/definitions` directory. Generate updated holidays as follows. ```sh cd vendor/holidays # Generate holiday definitions rake generate:definitions ``` Install the plugin and switch to the discourse root(not the plugin directory). ```sh # Collect all holiday regions into assets/javascripts/lib/regions.js bin/rails javascript:update_constants ``` ### Interactions with Other Plugins You can use an element of this plugin with the [Right Sidebar Blocks](https://github.com/discourse/discourse-right-sidebar-blocks) component. You'll want to ensure the desired route is enabled via the `events calendar categories` setting. In Right Sidebar Block's settings, the block name will be `upcoming-events-list`, and the params use this [syntax](https://momentjs.com/docs/#/displaying/format/), for example `MMMM D, YYYY`. ", Assign "at most 3 tags" to the expected json: {"id":"13629","tags":[]} "only from the tags list I provide: []" returns me the "expected json"
