Instead\n * all changes to the view state should be done using the StateManager which\n * will generate a new version of the view state with the requested changes.\n *\n * After any changes to the view state the module will call the render function\n * to ask the renderer to update the UI.\n *\n * General rules for this module:\n * 1.) Never modify viewState directly. All changes should be via the StateManager.\n * 2.) Call render() with the new state when you want to update the UI\n * 3.) Never modify the UI directly in this module. This module is only concerned\n * with the data in the view state.\n *\n * The general flow for a user interaction will be something like:\n * User interaction: User clicks \"confirm block\" button to block the other user\n * 1.) This module is hears the click\n * 2.) This module sends a request to the server to block the user\n * 3.) The server responds with the new user profile\n * 4.) This module generates a new state using the StateManager with the updated\n * user profile.\n * 5.) This module asks the Patcher to generate a patch from the current state and\n * the newly generated state. This patch tells the renderer what has changed\n * between the states.\n * 6.) This module gives the Renderer the generated patch. The renderer updates\n * the UI with changes according to the patch.\n *\n * @module core_message/message_drawer_view_conversation\n * @copyright 2018 Ryan Wyllie \n * @license http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later\n */\ndefine(\n[\n 'jquery',\n 'core/auto_rows',\n 'core/backoff_timer',\n 'core/custom_interaction_events',\n 'core/notification',\n 'core/pending',\n 'core/pubsub',\n 'core/str',\n 'core_message/message_repository',\n 'core_message/message_drawer_events',\n 'core_message/message_drawer_view_conversation_constants',\n 'core_message/message_drawer_view_conversation_patcher',\n 'core_message/message_drawer_view_conversation_renderer',\n 'core_message/message_drawer_view_conversation_state_manager',\n 'core_message/message_drawer_router',\n 'core_message/message_drawer_routes',\n 'core/emoji/auto_complete',\n 'core/emoji/picker'\n],\nfunction(\n $,\n AutoRows,\n BackOffTimer,\n CustomEvents,\n Notification,\n Pending,\n PubSub,\n Str,\n Repository,\n MessageDrawerEvents,\n Constants,\n Patcher,\n Renderer,\n StateManager,\n MessageDrawerRouter,\n MessageDrawerRoutes,\n initialiseEmojiAutoComplete,\n initialiseEmojiPicker\n) {\n\n // Contains a cache of all view states that have been loaded so far\n // which saves us having to reload stuff with network requests when\n // switching between conversations.\n var stateCache = {};\n // The current data representation of the view.\n var viewState = null;\n var loadedAllMessages = false;\n var messagesOffset = 0;\n var newMessagesPollTimer = null;\n var isRendering = false;\n var renderBuffer = [];\n // If the UI is currently resetting.\n var isResetting = true;\n // If the UI is currently sending a message.\n var isSendingMessage = false;\n // If the UI is currently deleting a conversation.\n var isDeletingConversationContent = false;\n // A buffer of messages to send.\n var sendMessageBuffer = [];\n // These functions which will be generated when this module is\n // first called.

Instead\n * all changes to the view state should be done using the StateManager which\n * will generate a new version of the view state with the requested changes.\n *\n * After any changes to the view state the module will call the render function\n * to ask the renderer to update the UI.\n *\n * General rules for this module:\n * 1.) Never modify viewState directly. All changes should be via the StateManager.\n * 2.) Call render() with the new state when you want to update the UI\n * 3.) Never modify the UI directly in this module. This module is only concerned\n * with the data in the view state.\n *\n * The general flow for a user interaction will be something like:\n * User interaction: User clicks \"confirm block\" button to block the other user\n * 1.) This module is hears the click\n * 2.) This module sends a request to the server to block the user\n * 3.) The server responds with the new user profile\n * 4.) This module generates a new state using the StateManager with the updated\n * user profile.\n * 5.) This module asks the Patcher to generate a patch from the current state and\n * the newly generated state. This patch tells the renderer what has changed\n * between the states.\n * 6.) This module gives the Renderer the generated patch. The renderer updates\n * the UI with changes according to the patch.\n *\n * @module core_message/message_drawer_view_conversation\n * @copyright 2018 Ryan Wyllie \n * @license http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later\n */\ndefine(\n[\n 'jquery',\n 'core/auto_rows',\n 'core/backoff_timer',\n 'core/custom_interaction_events',\n 'core/notification',\n 'core/pending',\n 'core/pubsub',\n 'core/str',\n 'core_message/message_repository',\n 'core_message/message_drawer_events',\n 'core_message/message_drawer_view_conversation_constants',\n 'core_message/message_drawer_view_conversation_patcher',\n 'core_message/message_drawer_view_conversation_renderer',\n 'core_message/message_drawer_view_conversation_state_manager',\n 'core_message/message_drawer_router',\n 'core_message/message_drawer_routes',\n 'core/emoji/auto_complete',\n 'core/emoji/picker'\n],\nfunction(\n $,\n AutoRows,\n BackOffTimer,\n CustomEvents,\n Notification,\n Pending,\n PubSub,\n Str,\n Repository,\n MessageDrawerEvents,\n Constants,\n Patcher,\n Renderer,\n StateManager,\n MessageDrawerRouter,\n MessageDrawerRoutes,\n initialiseEmojiAutoComplete,\n initialiseEmojiPicker\n) {\n\n // Contains a cache of all view states that have been loaded so far\n // which saves us having to reload stuff with network requests when\n // switching between conversations.\n var stateCache = {};\n // The current data representation of the view.\n var viewState = null;\n var loadedAllMessages = false;\n var messagesOffset = 0;\n var newMessagesPollTimer = null;\n var isRendering = false;\n var renderBuffer = [];\n // If the UI is currently resetting.\n var isResetting = true;\n // If the UI is currently sending a message.\n var isSendingMessage = false;\n // If the UI is currently deleting a conversation.\n var isDeletingConversationContent = false;\n // A buffer of messages to send.\n var sendMessageBuffer = [];\n // These functions which will be generated when this module is\n // first called.
