pandoc calls connect on Windows?

pandoc calls connect on Windows?

[Peter Wang]

Hi,

I'm using pandoc as part of a build system to generate API
documentation.  When pandoc is called within an MS Visual Studio build,
it produces this error message:

pandoc.exe: connect: failed (Cannot assign requested address (WSAEADDRNOTAVAIL))

Is it too far fetched that pandoc (or one of the libraries it depends on)
calls connect, and Visual Studio runs build commands in a restricted
environment?

Peter

I have no idea what could be causing this... I'm completely
ignorant of Windows programming.  It might help to know what
options pandoc was called with, though.

No options are required.

However, I have discovered that the problem does not occur with
pandoc 1.4 and earlier versions.

In 1.5, I added a dependency on network libraries, so pandoc
could take a URI as parameter.  My guess is that this is the
root of your problem...

Maybe the build system calls pandoc on something which looks like an 
URI, and pandoc tries to fetch it, instead of accessing a local file?

Indeed.  Thanks to you and John; I had forgotten about this new feature
in pandoc.

      readSource src = case parseURI src of
                            Just u  -> readURI u
                            Nothing -> UTF8.readFile src

parseURI parses "c:/bar.txt" as if the drive was a URI scheme, so
readURI is called.  Perhaps pandoc should limit itself to "http:" schemes?

In the meantime, I can work around this by using native Windows syntax
(backslashes) when on Windows.

Peter

PS. My testing was a bit hasty before.

Thanks for the help debugging this, everyone.
