Failure to run about pandoc-crossref HOT 14 CLOSED

Pandoc 1.14 (a.k.a. repo version) has changed API interface. pandoc-1.14 branch contains some work w.r.t. this change. You may want to try it and see if it works. I think it doesn't support external yaml settings as of yet though.

from pandoc-crossref.

And please do check your pandoc version, since PandocError type is introduced in 1.14, and should not be present in 1.13.2. If it is, then we messed up badly somewhere...

from pandoc-crossref.

If I have 1.13.2 (in /usr/local/bin) and 1.14 (in ~/.cabal/bin) installed simultaneously, but I don't include 1.14 in the $PATH, shouldn't it not try to run 1.14 (and give me 1.14 errors)?

Even if I explicitly tell it to use 1.13.2, I get the same errors:

~/.../filters/pandoc-crossref : /usr/local/bin/pandoc --version
pandoc 1.13.2
...

~/.../filters/pandoc-crossref : /usr/local/bin/pandoc -F pandoc-crossref.hs -i demo.md -o blah.html

    Couldn't match expected type ‘Pandoc’

Ooh. Switching to the 1.14 branch almost fixes it. There's only one error left. Still strange that 1.13.2 is giving all those 1.14-related errors, though.

pandoc: Error running filter pandoc-crossref.hs

It's likely 1.13.2 binary using 1.14 library from your ~/.ghc, where cabal installed it. I'm not sure how to fix it, but I'd advise to simply use a sandbox for pandoc-1.14, which does not pollute ghc package set in any way.

As for other error, what ghc version do you run?

from pandoc-crossref.

I'm using GHC 7.10.1.

I'd never heard of cabal sandboxes before (I live with Python; never touched Haskell). Reinstalling 1.14 now.

from pandoc-crossref.

Can't really test with ghc 7.10, but I can try to specify type, so maybe it helps. One moment.

from pandoc-crossref.

Ok, tried specifying type conservatively. Also merged support for settings file into pandoc-1.14 branch. See if this helps.

from pandoc-crossref.

Ack. Finally emerged from cabal hell with freshly sandboxed 1.14 install, and the binary seems to work fine. However, when using pandoc-crossref.hs as a filter, I get errors about Text.Pandoc and other libraries not existing. I'm absolutely sure this is because ghc isn't looking at the sandbox path (despite it being in my $PATH—when the filter is run, it doesn't know where to look for the import Text.Pandoc, etc. commands).

So this is totally off topic from this bug, but I have no idea how to connect the sandboxed version of 1.14 to the filter. Sorry! :)

from pandoc-crossref.

You can build an executable from within cabal sandbox and use that:

cabal --sandbox-config-file=/full/path/to/pandocs/cabal.sandbox.config exec -- ghc --make pandoc-crossref.hs

This will create pandoc-crossref executable, which you can then use with pandoc-1.14 as usual (i.e. pandoc -F pandoc-crossref ...). I will be adding cabal build file later, but for now this should do.

from pandoc-crossref.

Getting closer! I can compile pandoc-crossref just fine, but then it complains about not finding a file:

~/.../filters/pandoc-crossref : cabal --sandbox-config-file=/Users/andrew/Research/Markdown\ magic/pandoc_dev/cabal.sandbox.config exec -- ghc --make pandoc-crossref.hs

Try pandoc -F ./pandoc-crossref ..., since it's not in PATH.

from pandoc-crossref.

THAT'S IT. I hadn't thought to include ./, since I figured the command would see it in the current folder. Thanks so much!

In other news, it ran perfectly fine with no errors, so your conservative type specification worked.

from pandoc-crossref.

Glad to hear it. Closing this as resolved then.
