[Feature Request] Support for iOS 14 In-Line replies

[sabogalc]

Even if it starts off as view only, this would be a cool feature to have on the web client

@iandwelker in case you want to implement this:

1. To render replies, you'd want to pull the thread_originator_guid column from chat.db. You can kinda see in here (the line renderer), here (the message bubble itself that decides whether the line should get rendered), and here (code that does some of the processing of whether the message is a reply, whether it should show the reply line, how that reply line is gonna look, etc)

2. To send replies, refer to the following objc code:

// get the chat
    IMChat *chat = [BlueBubblesHelper getChat: data[@"chatGuid"]];
// get the message text
    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString: data[@"message"]];
// get the subject line, if any
    NSMutableAttributedString *subjectAttributedString = nil;
    if ([data objectForKey:(@"subject")] != [NSNull null]) {
        subjectAttributedString = [[NSMutableAttributedString alloc] initWithString: data[@"subject"]];
    }
// get the effect ID, if any
    NSString *effectId = nil;
    if ([data objectForKey:(@"effectId")] != [NSNull null]) {
        effectId = data[@"effectId"];
    }
    
// helper function to create a message
    void (^createMessage)(NSAttributedString*, NSAttributedString*, NSString*, NSString*) = ^(NSAttributedString *message, NSAttributedString *subject, NSString *effectId, NSString *threadIdentifier) {
// init an IMMessage with the text, subject, and effect ID
        IMMessage *messageToSend = [[IMMessage alloc] init];
        messageToSend = [messageToSend initWithSender:(nil) time:(nil) text:(message) messageSubject:(subject) fileTransferGUIDs:(nil) flags:(100005) error:(nil) guid:(nil) subject:(nil) balloonBundleID:(nil) payloadData:(nil) expressiveSendStyleID:(effectId)];
// add the thread ID for the reply
        messageToSend.threadIdentifier = threadIdentifier;
// send it
        [chat sendMessage:(messageToSend)];
    };
    
    if ([data objectForKey:(@"selectedMessageGuid")] != [NSNull null]) {
// get the message being replied to
        [BlueBubblesHelper getMessageItem:(chat) :(data[@"selectedMessageGuid"]) completionBlock:^(IMMessage *message) {
// get the specific IMMessagePartChatItem out of the message
            IMMessageItem *messageItem = (IMMessageItem *)message._imMessageItem;
            NSObject *items = messageItem._newChatItems;
            IMMessagePartChatItem *item;
            // sometimes items is an array so we need to account for that
            if ([items isKindOfClass:[NSArray class]]) {
                for(IMMessagePartChatItem* imci in (NSArray *)items) {
                    if([imci._item.guid isEqualToString:(data[@"selectedMessageGuid"])]) {
                        DLog(@"BLUEBUBBLESHELPER: %@", data[@"selectedMessageGuid"]);
                        item = imci;
                    }
                }
            } else {
                item = (IMMessagePartChatItem *)items;
            }
            NSString *identifier = @"";
// either reply to an existing thread or create a new thread
            if (message.threadIdentifier != nil) {
                identifier = message.threadIdentifier;
            } else {
                identifier = IMCreateThreadIdentifierForMessagePartChatItem(item);
            }
            createMessage(attributedString, subjectAttributedString, effectId, identifier);
        }];
    }

If you got more questions lmk!

@tneotia, your third link is now dead (the one that comes before "code that does some of the processing of whether the message is a reply, whether it should show the reply line, how that reply line is gonna look, etc"). Is this link a correct/updated one, or no?
