filename variable

filename variable

Hi all,

this is a very silly question but I don't find the answer in the
documentation.

Is there a filename variable that can be accessed in the templates?

I have two output files: html and pdf.

Can I do something like this in the output html?

<a href="$filename$.pdf">Download as PDF</a>

I know that I can set a metadata variable in the yaml part of the input
file, but I would like to avoid manual setting.

I'm not sure if there's an existing template variable for this (I don't see
one) but I think that this lua filter will work:

function Pandoc(pandoc)
  pandoc.meta.output_file = PANDOC_STATE.output_file
  return pandoc
end

Thanks a lot.

I tried to strip the extension like this:

function Pandoc(pandoc)
   pandoc.meta.output_file = PANDOC_STATE.output_file:sub(0, - 5)
   return pandoc
end

But this only works with a three character extension.

I guess it should be easy to strip everything after the colon with 
regexp, if one is not a regexp illiterate like me.

something like this perhaps?

local name = file:gsub('%.[a-z]*$', '')

(perhaps also allow digits in the extension, or anything other than dots)

but no there's a better way; see
https://pandoc.org/lua-filters.html#pandoc.path.split_extension

thanks a lot for this code snippet. It works.

I found this in the documentation but cannot apply this. I'll dig deeper 
into Lua.

Re: filename variable

[John MacFarlane]

The outputfile variable is set automatically and you can use it in your template.

However, you can't substitute the extension in the template itself; for that you need a filter.

Sorry, I missed that! For some reason I only searched for output-file.
