footnote trouble with email in return-address

[rnuske]

Sometimes it seems useful to include an email address in the return-address block (maybe to suggest a way for faster exchange of messages or ...).

linl seems to get confused if an email address is added to the return-address. It marks the email address with a superscript 1 indicating a footnote but does not print a footnote (eg. email_in_return_address.pdf)

As far as I understood the process: pandoc's "markdown to latex" converts all email address to \href{mailto:...}{\nolinkurl{...}} and the linl template.tex tries to do footnotes instead of hotlinks.

I think there is no need for a footnote in case of email addresses but couldn't come up with a solution. I guess even the mailto and nolinkurl stuff could be done away with but have no clue how communicate this to pandoc

Reproducible example, please, or the bug report may not exist...

alright, based on the linl-skeleton:

---
author:
- Aaron Wolen
opening: Dear Dirk,
closing: Sincerely,
address:
- Dirk Eddelbuettel
- 123 Street Rd
- Chicago, IL
return-address: 
- 456 Road St.
- New York, NY
- somebody@somewhere.tld
output: linl::linl

Oh, I see now. That may be a pandoc interaction.

I guess we can add 'allow for email address' as a feature request. I suspect it may be easiest to make it a new frontmatter idem rather than shoehorning it into address. But I just guessing at this point...

[rnuske]

that would be cool, thanks.

yep, the first half (converting somebody@somewhere.tld to \href{mailto:somebody@somewhere.tld}{\nolinkurl{somebody@somewhere.tld}}) absolutly. The second half (turning all \href{} into foontotes) is at least controlled by linl's template.tex. That's my guess.

[eddelbuettel]

That latter one has a toggle. You could turn that off for a start.

[eddelbuettel]

Tested and verified. Just add

inline-links: true

to your front-mastter. Now the link is part from the from address just as you specified.

We could close this, or keep it open as a 'wishlist' for a from-email field. May as well go with it and make the email a wee bit more visually distinctive. Thoughts, @aaronwolen ?

[rnuske]

just tried it. It works for the email but kills the other link in the example above [egestas fringilla](http://example.com)

[aaronwolen]

That's an interesting problem.

I agree it should be possible to include an email address and use the links as footnotes option but I'm not sure how best to make that happen.

One option would be to move the line redefining \href to the line following \opening in the template:

...
\opening{$opening$}
\renewcommand{\href}[2]{#2\footnote{\url{#1}}}
...

It's not pretty but it works. The question is would the change have any unintended side effects.

Let's leave this open for now.

We need a better long term solution but in the mean time we can workaround this by disabling Pandoc's autolink_bare_uris extension

output: 
  linl::linl:
    md_extensions: "-autolink_bare_uris"

[rnuske]

The md_extensions: "-autolink_bare_uris" approach looks promising.
My little tests showed good results and others seemed to have come up with the same solution for this problem.

Actually, I would prefer to put it into the linl function in R/linl.R, for instance in line 64:

base <- inherit_pdf_document(..., template = template, keep_tex = keep_tex,  md_extensions = "-autolink_bare_uris")
