different Last separator in for loop template

different Last separator in for loop template

Hi all, 

In pandoc template, I often use for loop and separator to define a list of 
author

Example with latex template : 

\author{by $for(author)$$author.name$$sep$, $endfor$}

Ideally I would like to have last author separated from the preivous one by 
"and" not ", "

\author{author1 and author2}

Is this possible in some way to have a different separator at the end or is 
it a feature request for https://github.com/jgm/doctemplates ? 

Thank you ! 

Christophe

It is possible to do this using the `allbutlast` and `last` filters.

E.g.

    \author{ by $for(author/allbutlast$$author.name$$sep$, $endfor$
             and $author/last$ }

The only downside is that it will produce weird results if there is only
a single author.

Oh thank you! I did not know those one. According to release note, this 
would require pandoc 2.10+
I am still lock to 2.7.3 in the editor though...

You could probably put the whole

   and $author/last$

inside $if(author/last)$...$endif$ to avoid the weird results.
