Hmm.

With the following file test.pandoc

- [] a

When I pipe it to the command that Neoformat is supposed to run, like follows:

cat test.pandoc | pandoc -f markdown+abbreviations+autolink_bare_uris+markdown_attribute+mmd_header_identifiers+mmd_link_attributes+mmd_title_block+tex_math_double_backslash+emoji -t markdown+raw_tex-native_spans-simple_tables-multiline_tables+emoji --normalize -s --wrap=auto --atx-headers | sed -e 's/\[/[/g' -e 's/\]/]/g'

I get the following output

-   \[\] a

And when I pipe the output to sed it also doesn't work.

echo "-   \[\] a" |  sed -e 's/\[/[/g' -e 's/\]/]/g'

produces

-   \[\] a

Edit: actually, I think sed is fine, but vim is escaping it weird.

sed -e 's/\\\[/[/g' -e 's/\\\]/]/g'
// goes to

sed -e 's/\[/[/g' -e 's/\]/]/g'

Will investigate further.

I think the number of backslashes in the regex may be the issue, but I can't see why that'd break now all of a sudden.

I think vim might be messing with the sed regex when it is used with system()

Docs related to system()

Some outputs to ponder

" 1. Pipe data to pandoc, which pipes to sed
let stdin = '-   [] a'
let cmd = 'pandoc -f markdown -t markdown --normalize -s --wrap=auto --atx-headers'
let sed = "sed -e 's/\\\[/[/g' -e 's/\\\]/]/g'"
let exe = cmd . ' | ' . sed
let stdout = systemlist(exe, stdin)

echom string(stdout)
" ['-   \[\] a']

" 2. Pass data to sed via stdin
let stdin = '-   \[\] a'
let sed = "sed -e 's/\\\[/[/g' -e 's/\\\]/]/g'"
let stdout = systemlist(sed, stdin)

echom string(stdout)
" ['-   \[\] a']

" 3. Echo data in shell to sed
let cmd = "echo '-   \[\] a'"
let sed = "sed -e 's/\\\[/[/g' -e 's/\\\]/]/g'"
let exe = cmd . ' | ' . sed
let stdout = systemlist(exe)

echom string(stdout)
" ['-   [] a']
