Convert to Asciidoc does nothing (visible)

[lefou]

Observed vs. expected behavior

After selecting a rather large readme.md file and clicking on "Convert to AsciiDoc", nothing happens, not conversion, not error message, no noticable CPU work.

I expected that the file gets converted (as it does in other cases).

Steps to reproduce

• Checkout project https://github.com/com-lihaoyi/os-lib
• Select the readme.md file in the project view
• Open the context menu and select "Convert to AsciiDoc"

Environment

Plugin Version: 0.37.54
IntelliJ IDEA Version: 2022.2.3 (Community Edition) and 2021.2.4 (Ultimate Edition)
Up-to-date Gentoo Linux on AMD64 with Kernel 5.15.59 on X11

Sorry to see this happend in that project, and thank for raising the issue.

I can reproduce the problem locally; instead of the conversion the IDE logs an error (there should be a small red blinking exclamation mark at the lower right corner of your IDE).

There seems that the following regex is causing some problems:

https://github.com/bodiam/markdown-to-asciidoc/blob/79096394029812b234c4546b126cda6041d2c6ac/src/main/java/nl/jworks/markdown_to_asciidoc/Converter.java#L44-L46

        if (markdown.contains("```")) {
            markdown = markdown.replaceAll("(?m)(?<!\n\n)(\\s*)```(\\w*\n)((?:\\1[^\n]*\n)+)\\1```", "\n$1```$2$3$1```");
        }

With the example you provided above, this leads to the following exception below. I won't have the time to dig into this in more details over the next days, still I hope to be able to analyze this soon.

As a workaround, please consider converting it with PanDoc.

Thanks for your fast response. In the meantime, I converted the file with kramdown-asciidoc, which works reasonable well. I had to edit cross-references though.
