MMC Pro 1.4 does not create an epub file even though it says it did.

MMC Pro 1.4 does not create a complete LaTeX file even though the checkbox to do so is checked.

The multimarkdown 6.05 command line tool, coincidentally does not emit an epub file when tasked to do so, it emits an HTML file.

The multimarkdown 6.05 command line tool, coincidentally, does not emit a complete LateX file when tasked to do so.

Clearing settings and rebooting does not effect the MMC Pro problem. This happens both on El Capitan and Sierra.

    Sorry you're having trouble -- sounds like there is something wrong with
    the file or settings you're using, as I have not had trouble with
    creating LaTeX/EPUB files and have not heard any other reports.

    Can you send me:

    1. The file(s) you're having trouble converting

    2. A screenshot of the settings you're using in MMD Converter

    3. A screenshot of the terminal command you tried that failed

    4. A copy of the incorrect output (EPUB and LaTeX) that you received so
    I can compare it to what I get

    If you send that I'll take a look and try to track down the problem.

    While I did email you the requested samples directly let me also include them here for your convenience, in archived form.

    Thanks for sending the files -- I did not receive any other email from you, so not sure what happened there.

    1. I can confirm there is something strange going on with EPUB output -- I am out of town for a couple of days but will fix it when I return and release an update. Thanks for pointing this out.

    2. The file you sent doesn't have enough metadata to generate a working LaTeX file. At a minimum you need a valid latex config metadata (such as article or tufte-handout). has an example. You also need to be sure you have installed the latex support files

    3. Command line does create epubs -- mmd2epub is the easiest shortcut, but can also use multimarkdown -b -t epub file.txt. Epub is a binary file, not a text file, so you can't pipe the output. You have to use batch mode.

    Thanks again!

    I'm back in town and working on the EPUB issue. I tracked down the issue (I think) -- long story short, EPUBs are created directly with the MMD library code(C), whereas other formats are returned as plain text and written to files from the application code (Objective-C).

    Apparently the two routines are handled differently by the macOS Sandbox -- and apparently, the difference appears differently depending on exactly how the app was compiled.

    I'm digging into it further, and hope to fix by later today or tomorrow.

    I think I've got this fixed. It works on my machine, but then again, so did earlier versions.

    1.0.5 has been submitted to the app store, and should be approved by tomorrow if not today.

    Let me know if it doesn't work!!

    The tips you shared educated me (for example to equate YAML with metadata) and made a bunch of things in MultiMarkdown6 work.

    I'll look for the updated MultiMarkdown Converter Pro application in the Mac App Store and test it out when it drops.

    Converter 1.5 was approved on the App Store. It seems to work fine for me -- including EPUBs.

    Let me know if you have any trouble, and thanks again for pointing this out!

    Converter 1.05 produced an ePub on the first try.
    And I see you've updated it with MultiMarkdown to version 6.07.

    It's my pleasure to work with you. I'm a huge fan of Markdown tools and open source in general. Finding software issues and interacting with the developer to resolve them is enjoyable for me.

    MultiMarkdown's raw speed is also quite impressive. Since you just updated MultiMarkdown to version 6.07 I cloned its source from your GitHub repository and compiled/installed it very easily and successfully on my Raspberry Pi 3. That is sweet code!

    I haven't gone back to do benchmark testing lately, but one of my goals in MMD v6 was performance. Commonmark managed to push the envelop quite a bit in that area, so I had something to shoot for.

    Glad you have found MMD helpful, and I hear you about the open source community and interactions!
