Prelude.!!: negative index

Prelude.!!: negative index

[Greg Bullock]

[-- Attachment #1.1: Type: text/plain, Size: 983 bytes --]

I'm just trying out pandoc for the first time.  The idea really appeals.  

Using

pandoc 1.19.2.1
Compiled with pandoc-types 1.17.0.4, texmath 0.9, skylighting 0.1.1.4

to convert my docx file to rst gives the subject error message:

C:\Users\Greg\Documents\Codes>pandoc --from=docx --to=rst --output=gug.rst 
gug.docx
pandoc: Prelude.!!: negative index


What might be happening?  How can I work around this?

That's certainly a bug in pandoc, not a mistake on your part!

I have a guess about what's going on.  It would be easiest
to test if you could send or link to an input docx file
sufficient to reproduce the problem.  If you can't do that,
could you try the following experiment?

    pandoc -f docx -t native -o gug.native gug.docx

Then search gug.native to see if it contains

    Header 0

at any point...

Thank you for the reply.

I'll try to create a small input docx file to demonstrate the problem.

Indeed gug.native contains two instances of Header 0, as seen in this 
snippet:

...
,BlockQuote
 [Para [Str "Appendix"]]
,Para [Str "A",Space,Str "Instructions",Space,Str "for",Space,Str "Adding",
Space,Str "an",Space,Str "Appendix",Space,Str "29"]
,Header 0 ("figures",[],[]) [Str "FIGURES"]
,Para [Strong [Str "Figure",Space,Str "Page"]]
,Para [Strong [Str "No",Space,Str "table",Space,Str "of",Space,Str "figures"
,Space,Str "entries",Space,Str "found."]]
,Header 0 ("tables",[],[]) [Str "TABLES"]
,Para [Strong [Str "Table",Space,Str "Page"]]
,Para [Strong [Str "No",Space,Str "table",Space,Str "of",Space,Str "figures"
,Space,Str "entries",Space,Str "found."]]
...

In a re-post of the original message, I reported that the problem seems to 
occur only when writing a reStructuredText file.  Converting the same docx 
file to another format (e.g., odt or html) works without complaint. (I'd 
tried to delete the original post and leave only the re-post, but it seems 
that didn't take effect, or didn't take effect in time.)

Thanks!  I've created an issue to track this:
https://github.com/jgm/pandoc/issues/3830
Please submit the docx file there, if you come up with it.
That would be helpful indeed.

I've uploaded to issue at github a simple input docx file demonstrating the 
behavior.  

The docx includes two lists, still empty, to show page numbers and 
reference links for tables and figures, should those ever get added to the 
document.
