Error when run command by pandoc.pipe with no output

[etclub]

Here is an example
pandoc.pipe('sh', {}, 'ls | grep none')

It reports

Error running sh (error code 1): <no output>
stack traceback:
        stdin:1: in main chunk

You can work around this by wrapping your call into a pcall (which is documented in the Lua manual). For instance: local success, value = pcall(pandoc.pipe, 'sh', {}, 'ls | grep none')

Good to know it.

@tarleb presumably this shouldn't raise an error; can the code be modified so it doesn't?

The command ls | grep doesnotexist exits with error code 1 and doesn't print anything, so the behavior of pandoc.pipe seems to be correct.
