Description
I use following pandoc-vim-syntax settings:
let g:pandoc#modules#disabled = ['menu', 'spell']
let g:pandoc#syntax#codeblocks#embeds#langs = ['vim', 'tex', 'sh', 'cpp']
let g:pandoc#formatting#textwidth = 80
let g:pandoc#folding#fold_fenced_codeblocks = 1
let g:pandoc#folding#fdc = 0
let g:pandoc#after#modules#enabled = ["tablemode"]
let g:pandoc#biblio#sources = "b"Imagine that there is an URL with double underscores within (a bit stupid and certainly rare, but for example links to C++ boost docs that I used may contain them). Here is an example:
# Example
Some [stupid link](http://exampe.com/stupid__link).
```vim
echo "Enjoy broken code block"
```
End.(I had to indent this example by 4 because I do not know how to write markdown in markdown, probably this is the only possible way :) )
In this example folding will be totally broken because pandocReferenceUrl has attribute display, i.e. it is getting skipped while the double underscores are accepted by the vim syntax engine.
Vim doc says:
Generally, you can use "display" for match and region items that meet these
conditions:
...
- The item does not allow other items to match that didn't match otherwise,
and that item may extend the match too far. Example for C: A match for a
"//" comment can't use "display", because a "/*" inside that comment would
match then and start a comment which extends past the end of the line.
As soon as display attribute of the pandocReferenceUrl exposes double underscores within URL and they do match, the folding gets broken.
Here is a little patch against it:
