chunkedhtml - metadata variable for template reset after first chunk

chunkedhtml - metadata variable for template reset after first chunk

[Martin Post]

[-- Attachment #1.1: Type: text/plain, Size: 1476 bytes --]

I’m running Pandoc from a shell script, with multiple passes. The HTML 
template I am using here is fairly complex and should be used both for html 
and chunkedhtml output.

In the template, I have placed a navigation in a conditional (simplified 
here):

$-- $if(document-type-chunked)$
<nav class="sitenav">
<a href="$next.url$">$next.title$</a>$ <a 
href="$previous.url$">$previous.title$</a>
</nav>
$-- $endif$

In the shell script, I set this meta variable (document-type-chunked):

pandoc --standalone $(basename $file) --to=chunkedhtml --metadata 
document-type-chunked=true --output=${outputname%.*}

The metadata variable is still true for the first page of the chunked 
output (index.html), but not for the remaining chunks, so they get no 
navigation.

Am I making a mistake?

I realize I could also put conditionals around each single navigation item 
($if(next.url)$), but it would be easier to build complex templates if I 
could pass a variable to the template.

Could this be resolved differently?

Thank you.

I haven't used chunked html, but did notice this in the manual. Not sure
whether this affects you here...


*The navigation links can be customized by adjusting the template. By
default, a table of contents is included only on the top page. To include
it on every page, set the toc variable manually.*

No, the toc is different from the chunkedhtml nav links (top, next.url, 
previous.url). And these are available. It’s just that the metadata 
variable that I use to conditionally place the navigation section is lost 
with --to=chunkedhtml.

Re: chunkedhtml - metadata variable for template reset after first chunk

[Martin Post]

I just built a from scratch test. Unfortunately, it seems that with output 
to chunkedhtml, variables are only used on the first page and then lost, so 
it’s not possible to do conditionals or use metadata in a template. But I 
may be missing something, so I’m not reporting this as a bug yet.

I’m using this, with a simple template:

pandoc
--standalone
--from=markdown
--to=chunkedhtml
--toc
--split-level=2
--template=chunking_test_template.htm
--defaults=chunking_test_metadata.yml
--metadata metavar1fromcommandline="This is the value of 
metavar1fromcommandline"
chunking_test_source.md
--output=chunking_test_output_folder

As seen in the attached screenshot, the variables set (1) in the Markdown 
file, (2) the YAML defaults file and (3) on the command line are present on 
“index.html”, but not on the following pages.
