marked 2 hangs when file is saved twice quickly

When I edit my markdown (MD) text in my favorite text editor, I noticed marked 2 hangs when i do a "double" save quickly one after another. I think it hangs when it is not done rendering, visually, the first save.

For example, I might write a new paragraph in a MD document. When I am done, I save it. Then, I noticed a typo (like a missing period). I quickly fix it and then save it. I think if the MD document is "big" and marked 2 is taking a little extra time rendering the first save and a 2nd save comes in, marked 2 hangs indefinitely (or rather I run out of patience). I close the document in Marked 2. Then, I try to quit/exit/close the Marked 2 app. At that point, my Mac tells me it is not responding and I will have to do a force quit.

I am using MacOS Mojave version 10.14.6.

    If you could please open Marked and select Help->Report an Issue from
    the menu bar, pasting the results of that into this thread will help me
    simulate your environment for testing. If possible, please also attach a
    file that causes the behavior for you. You can set this thread to
    private if you're willing to share with me but not publicly.

    I cannot share the document, unfortunately.

    Also, I noticed this is becoming more frequent. The initial save does not present any issues. But a subsequent save can cause Marked 2 to show a "blank" and completely white window. The time between each subsequent save makes a difference in how easily reproducible this is but I do notice as well that even if the time delta is long, marked 2 can get into this funky mode. It is easy to reproduce if the time delta is small.

    When I get into this situation, my MacBook's fan grows louder as that indicates that perhaps the Marked 2 code is in a tight loop which is heating up the CPU. I have to force quit that app.

    I use MacVIM as my editor. Just FYI.

    It's possible that something specific in the document is throwing Marked
    for a loop. Does this happen with any document?

    I don't know if this happens with other documents as I have only one document to edit at this time.

    Is there a way to isolate where in the document this problem is occurring? I can then go see that section. A document containing over thousands of line can be hard to figure out which line that is causing the problem.

    To help debug this problem, I did an "strace" or rather in MacOS lingo, dtruss, of the active process and capture that output into a file. I like to deliver the files to you in a private manner with some description of it. I see an "attach file" button below but I am not sure that is private. How do I deliver files to you in a private manner? The files are in plain text.

    Also, I went through the HTML generated form of the MD and used an HTML syntax analyzer on it. There were lots of warnings and some errors like duplicate ids and some minor typos. I fixed those but the problem still occurs.

    If you set this conversation to "Private", any attachment will only be
    seen by me and never indexed in search. If you need an alternate method,
    you can send it directly to [email blocked], but I'd ask that the
    conversation remain here and not in an email exchange.

    I don't think the issue will be cleared up by any process trace, nor
    would it be anything to do with the output markup. The easiest way to
    test with your large file is to create a copy and delete half the text.
    Test with that file and see if the issue persists. If not, you can try
    testing with the other half. If the issue then shows up, you know it's
    something in that half of the file and can start removing parts from
    there. If it doesn't, then it's likely being caused just by the size of
    the file, which would be odd but not unheard of and we could debug from

    Hi Brett,

    Okay. Thanks. Let me do that. The MD file is 101,389 bytes in size.
    However, our MD file contains a lot of HTML tags as well such as tables
    (where markdown cannot address), <p>, <a>. Mostly they are <p>'s and <a>'s.

    I am not sure that makes a difference.

    I will do your suggestion and try to isolate the problem by removing
    text. Please give me a few days to see if this method helps isolate the
    problem further.
