Yeah, that's fair. Technically, the markdown spec doesn't require a newline, but many parsers do, so we should probably just add a line there to be more widely compatible.

[marekkowalczyk]

A workaround is to disable the requirement for Pandoc to have a blank line before a heading. The extension to be blocked is blank_before_header with a - (dash) before its invocation.

The entire command is:

pandoc --from=markdown-blank_before_header jrnl.txt -o jrnl.pdf.

[marekkowalczyk]

In case you need a pandoc-compatible MD file with \n\n before headers:

pandoc --from=markdown-blank_before_header jrnl.txt -o jrnl.md

[MinchinWeb]

This is happening because the entries don't end with a newline. To fix it, it's a oneline addition to add a blank line after each entry.

But does the "fix" need to turn itself "off" for entries that do end with a newline? If we don't do that, then you're bound to get a mix of single and double empty lines above the level 3 headers...

[marekkowalczyk]

@MinchinWeb You might want to use sed after adding a newline to remove superfluous newlines. A bit crude but guarenteed to work.
