converting links to footnotes... including page number in footnote??

converting links to footnotes... including page number in footnote??

[-- Attachment #1.1: Type: text/plain, Size: 1427 bytes --]

Using pandoc with weasyprint pdf engine to turn the markdown files from a 
blog (static site generator does the html conversion) into a pdf for print.

Would it be possible, perhaps with a custom lua filter or some other 
mechanism, to add the page number of the linked-to page? The page numbers 
won't be known until pandoc has already created the document, and I don't 
know where in 'the pipeline' the lua filter intervenes compared to when the 
pages exist...?  And If the pages exist with their numbers earlier enough, 
is there an object or something from which lua can get the page number?

I haven't found anything about page numbers in 
https://pandoc.org/lua-filters.html#module-pandoc.utils ...am I looking in 
the wrong place? Can anyone tell me anything about this?

It's an intimidating rabbit hole for me, particularly because I see no 
mention of "page  number" there in the docs, which makes it seem kinda 
hopeless actually. But maybe one of you know the way and could point me in 
that direction?

[Bastien DUMONT]

The problem is that Pandoc does not produce the PDF document: it produces the intermediary HTML document that is processed by weasyprint to produce the PDF. So you cannot get page numbers in a Lua filter.

However, you can inject raw HTML code in the intermediary file (or in your CSS) that will make weasyprint print the page numbers. The question is whether such HTML code exists. It certainly would be possible to do this if you converted to PDF via LaTeX, ConTeXt or groff, but I don't know if it is possible via weasyprint.

Thanks! Yeah injecting html in the intermediary document doesn't sound very 
promising either (again, because the pages have to be built first before 
footnotes updated with page #s) so maybe I'll abandon weasyprint in this 
case, if this would be easy to do with a *Tex pdf engine. In that case... 
how would one go about this? Would a lua filter be more capable with a 
different pdf engine or would a different mechanism be used?

Re: converting links to footnotes... including page number in footnote??

['Håkon Wium Lie' via pandoc-discuss]

If you use Prince as the PDF generator, you can produce quite advanced footnotes:

  https://css4.pub/2022/footnotes/

Also, Prince supports sidenotes, aiming for the holy grail of Tufte-like layout:

  https://css4.pub
  https://css4.pub/2022/sidenotes/

To add the page number of the linked-to page (which was the original
question), Prince supports the "target-counter" feature in CSS.

  https://www.princexml.com/doc/gen-content/

This is often used to create ToCs:

  https://css4.pub/2022/toc/

(Prince is a commercial product, but free for non-commercial use. I work for the company.)

Prince looks decent, but I'm reluctant to use anything that's not freedom 
software.

Please find attached a basic implementation. As in the attached sample HMTL file, I suppose that the targets are marked with ids on spans and that you link to it via empty <a> elements. If you have a LaTeX installation, simply do `pandoc -L links-with-page-number.lua -o test.pdf test.html` to see the result.

Re: converting links to footnotes... including page number in footnote??

[user account]

[-- Attachment #1.1: Type: text/plain, Size: 5882 bytes --]

Thanks I wish that worked. I don't know what I'm doing wrong, here's what 
I've got…

`pandoc --version` says user data dir is `~/.local/share/pandoc` so I 
placed this file there as 
`~/.local/share/pandoc/links-with-page-number.lua` and did (just in case) 
`chmod +x` on it.

`pandoc -o test.pdf test.html` produces a 2page pdf as expected with no 
footnotes.

`pandoc -L links-with-page-number.lua -o test.pdf test.html` fails to 
produce pdf file with:
```
Error running filter links-with-page-number.lua:
links-with-page-number.lua: openBinaryFile: does not exist (No such file or 
directory)
```

There's no typo in my script name or command invocation. Using ~/.pandoc 
instead of ~/.local/share/pandoc doesn't make any difference, still get 
that same error.

Any ideas?

Re: converting links to footnotes... including page number in footnote??

[Bastien DUMONT]

Place the file under `~/.local/share/pandoc/filters`. You don't need the executable flag.

Re: converting links to footnotes... including page number in footnote??

[user account]

[-- Attachment #1.1: Type: text/plain, Size: 9281 bytes --]

oh a 'filters' subdir! Thanks. So now the pdf gets created w/o error, but 
there are not footnotes.

neither of these:
    pandoc -L links-with-page-number.lua -o test.pdf test.html
    pandoc -V links-as-notes -L links-with-page-number.lua -o test.pdf 
test.html
...creates pdf w/ footnotes, so there's no footnote to contain the page 
number of the linked-to page.

Something undesireable does happen though... I changed the paragraph with 
the link to:
<p>Here is a link to <a href="#thetarget">important words about the 
target</a>.</p>
...and the "important words about the target" get removed altogether. Those 
should not be removed, just the <a> tags around them should be removed.

Thanks for the help so far. I'm excited to see a lua filter in action for 
my first time. Very curious about the api... I presume pandoc is looking 
for functions with particular names like Link and Span? Would you mind 
confirming... this https://pandoc.org/lua-filters.html#type-link is the 
proper spot in the docs for referencing Link in this context... right?

I imagine this working example produce footnotes w/ page numbers for you in 
your environment...? Any idea what I could inspect to try to get it working 
in mine?

Re: converting links to footnotes... including page number in footnote??

[Bastien DUMONT]

My filter only shows how one can inject raw code to get references by page number in LaTeX. Without any example, I don't really understand what you say about footnotes and so on, but the basic mechanism is here, now you can adapt the filter to your needs.

Re: converting links to footnotes... including page number in footnote??

[user account]

[-- Attachment #1.1: Type: text/plain, Size: 13171 bytes --]

Ok, gotcha! Could you point me to an example of how that page number could 
be printed somewhere?

My goal is this, HTML:
<p>Here's text with <a href="/some-blog-post">anchor text</a>.</p>

Becomes a paragraph in the pdf document:
Here's text with anchor text[1].

And then in the footer, is a footnote:
1) See <scripted caption> one page #7.

...where page 7 is the where the /some-blog-post is now located in this pdf.

Does that make sense?

Re: converting links to footnotes... including page number in footnote??

[-- Attachment #1.1: Type: text/plain, Size: 18818 bytes --]

That is AWESOME - thank you!!!

I see that the function `function Span(span)` turns
    1 See on page #??.
in to
    1 See on page #2.
but I can't for the life of me figure out how.

Would you mind explaining that?

I've been digging through the docs, but got a lot of headscratching going 
on, many more questions than answers.

TeX (LaTeX or ConTeXt) has no information about pages and their contents
