Changing LaTeX output for citations inside footnotes

Changing LaTeX output for citations inside footnotes

[Lyndon Drake]

[-- Attachment #1.1: Type: text/plain, Size: 1404 bytes --]

Hi,

So this is a slightly odd request, which really comes because of the 
unusual behaviour of the specific BibLaTeX bibliography style I'm using. In 
that style, \textcite inside a footnote produces an unwanted result. \cite 
produces the expected output. I have generally just gone through and 
hand-edited my Pandoc-produced LaTeX files when they get to the final copy 
stage, but that's painful, and I also thought that maybe this is possible 
to do in a Lua filter.

But I don't quite know where to start - obviously this is a bit different 
from the internal Pandoc citations. I'm going to begin the filter with this:

if FORMAT:match 'latex' then <https://pandoc.org/lua-filters.html#cb9-3> 
function 

but what would the function be? If it is Footnote, then I don't really want 
the AST, I want the LaTeX that forms the footnote contents, and I suppose 
then I can just replace any occurrences of the string \textcite with the 
string \cite?

Any help would be awesome!

Best,
Lyndon

AW: Changing LaTeX output for citations inside footnotes

[denis.maier-NSENcxR/0n0]

I can't come up with a code example now, bit you can use the walk function (https://pandoc.org/lua-filters.html#type-block:walk) to modify the citations with a given mode inside notes. You'll need to build the citation via Pandoc.RawInline
Maybe that would be a good example of a new style Lua writer.

Thanks for this. I can see how that could work.

Can you point me to another example that uses the walk function?

Regarding a new-style Lua writer, is there a way to get the current LaTeX 
writer as Lua code? Or is it just the Haskell code? (I once knew Haskell 
but that was rather a long time ago.)

AW: Changing LaTeX output for citations inside footnotes

[denis.maier-NSENcxR/0n0]

[-- Attachment #1: Type: text/plain, Size: 4782 bytes --]

What kind of example do you need? I only know about the examples in the documentation.

I think this here is a nice one :
https://pandoc.org/lua-filters.html#modifying-pandocs-manual.txt-for-man-pages

Or : the new style writer
https://pandoc.org/custom-writers.html#example-modified-markdown-writer

So, something like this here could be start:

```
function Writer(doc, opts)
  local filter = {
    Note = function(el)
        return el:walk {
          Cite = function(el)
            -- processing logic
           return pandoc.RawInline('latex', '\\cite[prenote][postnote]{key}')
          end
      }
    end
  }
  return pandoc.write(doc:walk(filter), 'latex', opts)
end
```

I don’t think you can get the current writer in Lua.

Thanks for this - exactly what I needed. I've added my attempt at the code 
below, but I must be missing some basic part of it because it doesn't do 
anything. I added a couple of print statements that never get executed:

```
function Writer(doc, opts)
    print "got here"
    local filter = {
        Note = function(el)
            return el:walk {
                Cite = function(el)
                    -- processing logic
                    print "got further"
                    local citation = ""
                    if #el.citations > 1 then
                        if citations[1].mode == "AuthorInText" then
                            citation = '\\textcites*'
                        elseif citations[1].mode == "SuppressAuthor" then
                            citation = '\\cites*'
                        elseif citations[1].mode == "NormalCitation" then
                            citation = '\\cites'
                        end
                    else
                        if citations[1].mode == "AuthorInText" then
                            citation = '\\textcite*'
                        elseif citations[1].mode == "SuppressAuthor" then
                            citation = '\\cite*'
                        elseif citations[1].mode == "NormalCitation" then
                            citation = '\\cite'
                        end
                    end
                    for c in el.citations do
                        if c.prefix ~= "" then
                            citation = citation .. '[' .. c.prefix .. ']'
                        end
                        if c.suffix ~= "" then
                            citation = citation .. '[' .. c.suffix .. ']'
                        end
                        citation = citation .. '{' .. c.id .. '}'
                    end
                    return pandoc.RawInline('latex', citation)
                end
            }
        end
    }
    return pandoc.write(doc:walk(filter), 'latex', opts)
end
```

Apologies for what must be a very basic question, but what am I missing 
here?

AW: Changing LaTeX output for citations inside footnotes

How do you run this ?
I’ve tested with a minimal markdown file :

```markdown
asdf
```

Run with :
pandoc asdf.md -t mylatex.lua

Result :
got here
asdf

So, it prints the first print statement of the writer.

I think this here is a nice one :

Or : the new style writer
https://pandoc.org/custom-writers.html#example-modified-markdown-writer

So, something like this here could be start:

```
function Writer(doc, opts)
  local filter = {
    Note = function(el)
        return el:walk {
          Cite = function(el)
            -- processing logic
           return pandoc.RawInline('latex', '\\cite[prenote][postnote]{key}')
          end
      }
    end
  }
  return pandoc.write(doc:walk(filter), 'latex', opts)
end
```

I don’t think you can get the current writer in Lua.

Thanks for this. I can see how that could work.

Can you point me to another example that uses the walk function?

Regarding a new-style Lua writer, is there a way to get the current LaTeX writer as Lua code? Or is it just the Haskell code? (I once knew Haskell but that was rather a long time ago.)

Maybe that would be a good example of a new style Lua writer.

Betreff: Changing LaTeX output for citations inside footnotes

Hi,

So this is a slightly odd request, which really comes because of the unusual behaviour of the specific BibLaTeX bibliography style I'm using. In that style, \textcite inside a footnote produces an unwanted result. \cite produces the expected output. I have generally just gone through and hand-edited my Pandoc-produced LaTeX files when they get to the final copy stage, but that's painful, and I also thought that maybe this is possible to do in a Lua filter.

But I don't quite know where to start - obviously this is a bit different from the internal Pandoc citations. I'm going to begin the filter with this:

if FORMAT:match 'latex' then <https://pandoc.org/lua-filters.html#cb9-3> function

but what would the function be? If it is Footnote, then I don't really want the AST, I want the LaTeX that forms the footnote contents, and I suppose then I can just replace any occurrences of the string \textcite with the string \cite?

Any help would be awesome!

Best,
Lyndon

My command line is:

pandoc -dbookends-latex --template 
/Users/lyndon/.local/share/pandoc/templates/book.latex 
--lua-filter=/Users/lyndon/.local/share/pandoc/filters/latex-footcite.lua 
-s -o thesis_jeremiah_32.tex jer-32-thesis.md

It's definitely picking up the lua file because if I have a syntax error, 
pandoc tells me. But I don't get any output.

AW: Changing LaTeX output for citations inside footnotes

[denis.maier-NSENcxR/0n0]

That's the problem. This is a writer, not a filter. So you need to call it via
-t latex-footcite.lua

I’ve tested with a minimal markdown file :

```markdown

Run with :
pandoc asdf.md -t mylatex.lua

Result :
got here
asdf

So, it prints the first print statement of the writer.

Thanks for this - exactly what I needed. I've added my attempt at the code below, but I must be missing some basic part of it because it doesn't do anything. I added a couple of print statements that never get executed:

```

        Note = function(el)
            return el:walk {

                    -- processing logic
                    print "got further"
                    local citation = ""
                    if #el.citations > 1 then

Apologies for what must be a very basic question, but what am I missing here?

I think this here is a nice one :

Or : the new style writer
https://pandoc.org/custom-writers.html#example-modified-markdown-writer

So, something like this here could be start:

```
function Writer(doc, opts)
  local filter = {
    Note = function(el)
        return el:walk {
          Cite = function(el)
            -- processing logic
           return pandoc.RawInline('latex', '\\cite[prenote][postnote]{key}')
          end
      }
    end
  }
  return pandoc.write(doc:walk(filter), 'latex', opts)
end
```

I don’t think you can get the current writer in Lua.

Thanks for this. I can see how that could work.

Can you point me to another example that uses the walk function?

Regarding a new-style Lua writer, is there a way to get the current LaTeX writer as Lua code? Or is it just the Haskell code? (I once knew Haskell but that was rather a long time ago.)

Maybe that would be a good example of a new style Lua writer.

Betreff: Changing LaTeX output for citations inside footnotes

Hi,

So this is a slightly odd request, which really comes because of the unusual behaviour of the specific BibLaTeX bibliography style I'm using. In that style, \textcite inside a footnote produces an unwanted result. \cite produces the expected output. I have generally just gone through and hand-edited my Pandoc-produced LaTeX files when they get to the final copy stage, but that's painful, and I also thought that maybe this is possible to do in a Lua filter.

But I don't quite know where to start - obviously this is a bit different from the internal Pandoc citations. I'm going to begin the filter with this:

if FORMAT:match 'latex' then <https://pandoc.org/lua-filters.html#cb9-3> function

but what would the function be? If it is Footnote, then I don't really want the AST, I want the LaTeX that forms the footnote contents, and I suppose then I can just replace any occurrences of the string \textcite with the string \cite?

Any help would be awesome!

Best,
Lyndon

Re: Changing LaTeX output for citations inside footnotes

[Lyndon Drake]

[-- Attachment #1.1: Type: text/plain, Size: 9977 bytes --]

So I have the citation prefix, which I guess I have to convert to a valid 
LaTeX string. How can I take an Inlines and LaTeX-ify it to a string?

Re: Changing LaTeX output for citations inside footnotes

[Sukil Etxenike arizaleta]

[-- Attachment #1: Type: text/plain, Size: 12619 bytes --]

I don't know, but the building blocks you'll need are `pandoc.stringify` 
which takes any object and converts it into a string, and 
`pandoc.RawBlock` or `pandoc.RawInline` which convert a string into a 
raw block or inline, and take the format as first argument and the 
string as second.

Hth,

Sukil

Re: Changing LaTeX output for citations inside footnotes

[Lyndon Drake]

[-- Attachment #1.1: Type: text/plain, Size: 14584 bytes --]

Thanks for all the help - definitely getting somewhere now!

I guess what I want to avoid is replicating in my not-great-Lua code all 
the work Pandoc already has to take a string of Markdown and convert it to 
LaTeX. I'm using pandoc.write to attempt that, and it seems to be working 
to some degree. The code as it is now is below. I have two problems:

1. This Markdown input [@Haran1982 165 n. 9, 172] gets converted by my 
calling of pandoc.write into:

```
\cite[165

n.~9,

172]{Haran1982}
```

and I can't figure out why the blank lines are turning up. I imagine I need 
to do something more clever with the Inlines?


2. Despite the fact that my output in the terminal shows that I am 
constructing the citetext variable as I am intending to, and I have this 
line of code:

                    return pandoc.RawInline('latex', citetext)

The output .tex file still has the normal Pandoc citations. In other words, 
my writer is constructing a nice LaTeX string with what I want in it, and 
then discards it in favour of the normal Pandoc code, which is a little bit 
depressing.

Can anyone spot what I'm missing now?

Best,
Lyndon

Re: Changing LaTeX output for citations inside footnotes

[Sukil Etxenike arizaleta]

[-- Attachment #1: Type: text/plain, Size: 19137 bytes --]

Hi,

For your first problem, when you do pandoc.write, as a minimum a block 
is created, which, I believe, is normally a paragraph. So, don't call 
pandoc.write. I guess you can concatenate the prefix, citation and 
suffix and pass them to the pandoc.RawInline function.


For your second problem, I am guessing you are using --citeproc in your 
defaults file. If that is the case, try: 1) putting the defaults file 
after the filter; or 2) specifying --citeproc manually, also after the 
filter.

Hth,

Sukil

Re: Changing LaTeX output for citations inside footnotes

[Lyndon Drake]

[-- Attachment #1.1: Type: text/plain, Size: 16988 bytes --]

Hi Sukil,

Thanks, you were quite correct about the second problem. I've amended that 
and it now works, at least in the sense that it is altering the output in 
the general way I want.

On the first problem, I can just pandoc.stringify the prefix and suffix, 
and concatenate. The problem with that is I will then lose any Markdown 
formatting, which is not entirely uncommon in a prefix, and even 
occasionally in a suffix. I can work around it for this document, I guess, 
by just being careful not to use any Markdown formatting in these 
instances, but I'd love to find a way to take a set of Inlines and convert 
it to a format without adding a block.

Re: Changing LaTeX output for citations inside footnotes

[Sukil Etxenike arizaleta]

[-- Attachment #1: Type: text/plain, Size: 22867 bytes --]

I believe you can't create a pandoc document without any block. Two 
possibilities come to mind:

1. Round tripping: After fixing the citation, read it as LaTeX, and 
maybe, run pandoc.utils.blocks_to_inlines. (Hey, I never said it 
wouldn't be messy). May not work, even.

2. Simply delete all paragraph markers: in your case with: 
citetext:gsub("\n*", " ")

Hth,

Sukil

Nice, the :gsub does the trick (once I replaced \n* with \n+).

Thanks again, really appreciate the help with all this. Hopefully I can

Re: Changing LaTeX output for citations inside footnotes

[Lyndon Drake]

[-- Attachment #1.1: Type: text/plain, Size: 20849 bytes --]

Not really, because the issue is that Pandoc returns a doc, not a list of 
blocks. So blocks_to_inlines doesn't actually work. But the gsub trick 
works well enough to get around the issue, thankfully.

Re: Changing LaTeX output for citations inside footnotes

[Lyndon Drake]

[-- Attachment #1.1: Type: text/plain, Size: 26149 bytes --]

Well, below is the code as it is at the moment… I still need a Pandoc 
object to pass to pandoc.write, so even if I use blocks_to_inlines, I'm not 
sure what I'd then do to produce the output I'm after?

```
function Writer(doc, opts)
    local filter = {
        Note = function(el)
            return el:walk {
                Cite = function(el)
                    -- processing logic
                    local citetext = ""
                    if #el.citations > 1 then
                        if el.citations[1].mode == "AuthorInText" then
                            citetext = '\\cites'
                        elseif el.citations[1].mode == "SuppressAuthor" then
                            citetext = '\\parencites*'
                        elseif el.citations[1].mode == "NormalCitation" then
                            citetext = '\\parencites'
                        end
                    else
                        if el.citations[1].mode == "AuthorInText" then
                            citetext = '\\cite'
                        elseif el.citations[1].mode == "SuppressAuthor" then
                            citetext = '\\parencite*'
                        elseif el.citations[1].mode == "NormalCitation" then
                            citetext = '\\parencite'
                        end
                    end
                    for _, c in pairs(el.citations) do
                        if #c.prefix > 0 then
                            local doc = pandoc.Pandoc(c.prefix)
                            local citeprefix = pandoc.write(doc, 'latex')
                            citetext = citetext .. '[' .. citeprefix .. ']'
                        end
                        if #c.suffix > 0 then
                            local doc = pandoc.Pandoc(c.suffix)
                            local citesuffix = pandoc.write(doc, 'latex')
                            citetext = citetext .. '[' .. citesuffix .. ']'
                        end
                        citetext = citetext .. '{' .. c.id .. '}'
                    end
                    citetext = citetext:gsub("\n+", " ")                    
                    print(citetext)
                    return pandoc.RawInline('latex', citetext)
                end
            }
        end
    }
    return pandoc.write(doc:walk(filter), 'latex', opts)
end
```

Betreff: Re: Changing LaTeX output for citations inside footnotes

Well, below is the code as it is at the moment… I still need a Pandoc object to pass to pandoc.write, so even if I use blocks_to_inlines, I'm not sure what I'd then do to produce the output I'm after?

```
function Writer(doc, opts)
    local filter = {
        Note = function(el)
            return el:walk {
                Cite = function(el)
                    -- processing logic
                    local citetext = ""
                    if #el.citations > 1 then
                        if el.citations[1].mode == "AuthorInText" then
                            citetext = '\\cites'
                        elseif el.citations[1].mode == "SuppressAuthor" then
                            citetext = '\\parencites*'
                        elseif el.citations[1].mode == "NormalCitation" then
                            citetext = '\\parencites'
                        end
                    else
                        if el.citations[1].mode == "AuthorInText" then
                            citetext = '\\cite'
                        elseif el.citations[1].mode == "SuppressAuthor" then
                            citetext = '\\parencite*'
                        elseif el.citations[1].mode == "NormalCitation" then
                            citetext = '\\parencite'
                        end
                    end
                    for _, c in pairs(el.citations) do
                        if #c.prefix > 0 then
                            local doc = pandoc.Pandoc(c.prefix)
                            local citeprefix = pandoc.write(doc, 'latex')
                            citetext = citetext .. '[' .. citeprefix .. ']'
                        end
                        if #c.suffix > 0 then
                            local doc = pandoc.Pandoc(c.suffix)
                            local citesuffix = pandoc.write(doc, 'latex')
                            citetext = citetext .. '[' .. citesuffix .. ']'
                        end
                        citetext = citetext .. '{' .. c.id .. '}'
                    end
                    citetext = citetext:gsub("\n+", " ")
                    print(citetext)
                    return pandoc.RawInline('latex', citetext)
                end
            }
        end
    }
    return pandoc.write(doc:walk(filter), 'latex', opts)
end

But doc.blocks, which is the actual content of the doc, is a list of blocks, which you can pass to blocks_to_inlines. Don't forget to pass `{pandoc.Space()}` as the second argument!

Not really, because the issue is that Pandoc returns a doc, not a list of blocks. So blocks_to_inlines doesn't actually work. But the gsub trick works well enough to get around the issue, thankfully.

Nice, the :gsub does the trick (once I replaced \n* with \n+).

Thanks again, really appreciate the help with all this. Hopefully I can start to build some more Lua filters/writers now. It's a great system (thanks John MacFarlane!).

I believe you can't create a pandoc document without any block. Two possibilities come to mind:

1. Round tripping: After fixing the citation, read it as LaTeX, and maybe, run pandoc.utils.blocks_to_inlines. (Hey, I never said it wouldn't be messy). May not work, even.

2. Simply delete all paragraph markers: in your case with: citetext:gsub("\n*", " ")

Hi Sukil,

Thanks, you were quite correct about the second problem. I've amended that and it now works, at least in the sense that it is altering the output in the general way I want.

On the first problem, I can just pandoc.stringify the prefix and suffix, and concatenate. The problem with that is I will then lose any Markdown formatting, which is not entirely uncommon in a prefix, and even occasionally in a suffix. I can work around it for this document, I guess, by just being careful not to use any Markdown formatting in these instances, but I'd love to find a way to take a set of Inlines and convert it to a format without adding a block.

Hi,

For your first problem, when you do pandoc.write, as a minimum a block is created, which, I believe, is normally a paragraph. So, don't call pandoc.write. I guess you can concatenate the prefix, citation and suffix and pass them to the pandoc.RawInline function.



For your second problem, I am guessing you are using --citeproc in your defaults file. If that is the case, try: 1) putting the defaults file after the filter; or 2) specifying --citeproc manually, also after the filter.

Hth,

Sukil

Thanks for all the help - definitely getting somewhere now!

I guess what I want to avoid is replicating in my not-great-Lua code all the work Pandoc already has to take a string of Markdown and convert it to LaTeX. I'm using pandoc.write to attempt that, and it seems to be working to some degree. The code as it is now is below. I have two problems:

1. This Markdown input [@Haran1982 165 n. 9, 172] gets converted by my calling of pandoc.write into:

```
\cite[165

n.~9,

172]{Haran1982}
```

and I can't figure out why the blank lines are turning up. I imagine I need to do something more clever with the Inlines?


2. Despite the fact that my output in the terminal shows that I am constructing the citetext variable as I am intending to, and I have this line of code:

                    return pandoc.RawInline('latex', citetext)

The output .tex file still has the normal Pandoc citations. In other words, my writer is constructing a nice LaTeX string with what I want in it, and then discards it in favour of the normal Pandoc code, which is a little bit depressing.

Can anyone spot what I'm missing now?

Best,
Lyndon

I don't know, but the building blocks you'll need are `pandoc.stringify` which takes any object and converts it into a string, and `pandoc.RawBlock` or `pandoc.RawInline` which convert a string into a raw block or inline, and take the format as first argument and the string as second.

My command line is:

pandoc -dbookends-latex --template /Users/lyndon/.local/share/pandoc/templates/book.latex --lua-filter=/Users/lyndon/.local/share/pandoc/filters/latex-footcite.lua -s -o thesis_jeremiah_32.tex jer-32-thesis.md

It's definitely picking up the lua file because if I have a syntax error, pandoc tells me. But I don't get any output.

I’ve tested with a minimal markdown file :

Run with :
pandoc asdf.md -t mylatex.lua

Result :
got here

So, it prints the first print statement of the writer.

Betreff: Re: Changing LaTeX output for citations inside footnotes

Thanks for this - exactly what I needed. I've added my attempt at the code below, but I must be missing some basic part of it because it doesn't do anything. I added a couple of print statements that never get executed:

```
function Writer(doc, opts)
print "got here"
local filter = {
Note = function(el)
return el:walk {
Cite = function(el)
-- processing logic
print "got further"
local citation = ""
if #el.citations > 1 then
if citations[1].mode == "AuthorInText" then
citation = '\\textcites*'
elseif citations[1].mode == "SuppressAuthor" then
citation = '\\cites*'
elseif citations[1].mode == "NormalCitation" then
citation = '\\cites'
end
else
if citations[1].mode == "AuthorInText" then
citation = '\\textcite*'
elseif citations[1].mode == "SuppressAuthor" then
citation = '\\cite*'
elseif citations[1].mode == "NormalCitation" then
citation = '\\cite'
end
end
for c in el.citations do
if c.prefix ~= "" then
citation = citation .. '[' .. c.prefix .. ']'
end
if c.suffix ~= "" then
citation = citation .. '[' .. c.suffix .. ']'
end
citation = citation .. '{' .. c.id<http://c.id><http://c.id> .. '}'
end
return pandoc.RawInline('latex', citation)
end
}
end
}
return pandoc.write(doc:walk(filter), 'latex', opts)
end
```

Apologies for what must be a very basic question, but what am I missing here?

I think this here is a nice one :

Or : the new style writer
https://pandoc.org/custom-writers.html#example-modified-markdown-writer

So, something like this here could be start:

```
function Writer(doc, opts)
local filter = {
Note = function(el)
return el:walk {
Cite = function(el)
-- processing logic
return pandoc.RawInline('latex', '\\cite[prenote][postnote]{key}')
end
}
end
}
return pandoc.write(doc:walk(filter), 'latex', opts)
end

I don’t think you can get the current writer in Lua.

Thanks for this. I can see how that could work.

Can you point me to another example that uses the walk function?

Regarding a new-style Lua writer, is there a way to get the current LaTeX writer as Lua code? Or is it just the Haskell code? (I once knew Haskell but that was rather a long time ago.)

Maybe that would be a good example of a new style Lua writer.

Betreff: Changing LaTeX output for citations inside footnotes

Hi,

So this is a slightly odd request, which really comes because of the unusual behaviour of the specific BibLaTeX bibliography style I'm using. In that style, \textcite inside a footnote produces an unwanted result. \cite produces the expected output. I have generally just gone through and hand-edited my Pandoc-produced LaTeX files when they get to the final copy stage, but that's painful, and I also thought that maybe this is possible to do in a Lua filter.

But I don't quite know where to start - obviously this is a bit different from the internal Pandoc citations. I'm going to begin the filter with this:

if FORMAT:match 'latex' then <https://pandoc.org/lua-filters.html#cb9-3> function

but what would the function be? If it is Footnote, then I don't really want the AST, I want the LaTeX that forms the footnote contents, and I suppose then I can just replace any occurrences of the string \textcite with the string \cite?

Any help would be awesome!

Best,
Lyndon

Yes, and I have been using it successfully now for a little while. Thank

(using the gsub trick) as below. I should probably take all the `print`

            return el:walk {
