How do I replace a string in all text that pandoc converts, i.e. how do I do this with a filter?

[-- Attachment #1.1: Type: text/plain, Size: 802 bytes --]

I've been trying to replace markdown/Obsidian highlights "==" either with 
something that LaTeX can use e.g. \hl or just delete it/replace it with 
nothing, but I can't figure out how to do this.

I've tried this:
function Str (str)  
str.text = string.upper(str.text) 
return str 
end

But I can't even figure out where I'm meant to put my own text?

How do I rpelace == with " "?

Thanks!

I've tried this: 

return {
  {
    Para = function (elem)
      if elem.content[1].text == "{{helloworld}}" then
        return pandoc.RawBlock('html','<div>abc</div>')
      else
        return elem
      end
    end,
  }
}

but that only gets rid of {{helloworld}}, it doesn't replace it with 
anything. Sadly this doens't work for "==", i.e. those don't disappear.

What exactly are you doing? Your output format is html? I’ve just tested this and it seems to work.

```cmd
C:\Users\denis\Downloads\filter>cat test.md
asf

{{helloworld}}

asf
C:\Users\denis\Downloads\filter>pandoc test.md
<p>asf</p>
<p>{{helloworld}}</p>
<p>asf</p>

C:\Users\denis\Downloads\filter>pandoc test.md -L filter.lua
<p>asf</p>
<div>abc</div>
<p>asf</p>
```

No, my intended output is a PDF file. Does that change anything? Could you 
tell me what exactly you put in filter.lua?
Thanks!

AW: How do I replace a string in all text that pandoc converts, i.e. how do I do this with a filter?

[denis.maier-NSENcxR/0n0]

[-- Attachment #1: Type: text/plain, Size: 4537 bytes --]

Just your example filter:

```lua
return {
  {
    Para = function (elem)
      if elem.content[1].text == "{{helloworld}}" then
        return pandoc.RawBlock('html','<div>abc</div>')
      else
        return elem
      end
    end,
  }
}
```

The problematic line is this: return pandoc.RawBlock('html','<div>abc</div>')
This adds a raw block that will only come in to effect when your output format is html.

If your target ist latex, you’ll need something like this: return pandoc.RawBlock('latex','\\whatever{abc}')

```cmd
pandoc test.md -L filter.lua -t latex
asf

\whatever{abc}

asf
```

AW: How do I replace a string in all text that pandoc converts, i.e. how do I do this with a filter?

[denis.maier-NSENcxR/0n0]

You are matching against the whole paragraph (para). So, when the first element in your paragraph matches your search string, you'll replace the whole paragraph with the return value of your function. (Which is a block element, not an inline element.)

Use the example from here instead:
https://pandoc.org/lua-filters.html#macro-substitution

YES! that works! But can you tell me why it replaces the whole line? Can't I do this in running text?
Thanks!
return {
  {
    Para = function (elem)
      if elem.content[1].text == "{{helloworld}}" then
        return pandoc.RawBlock('latex','abc')

Just your example filter:

```lua
return {

        return elem

    end,

}
```

The problematic line is this: return pandoc.RawBlock('html','<div>abc</div>')
This adds a raw block that will only come in to effect when your output format is html.

If your target ist latex, you’ll need something like this: return pandoc.RawBlock('latex','\\whatever{abc}')

```cmd
pandoc test.md -L filter.lua -t latex
asf

\whatever{abc}

asf
```

No, my intended output is a PDF file. Does that change anything? Could you tell me what exactly you put in filter.lua?
Thanks!

Betreff: Re: How do I replace a string in all text that pandoc converts, i.e. how do I do this with a filter?

I've tried this:

return {
  {
    Para = function (elem)
      if elem.content[1].text == "{{helloworld}}" then
        return pandoc.RawBlock('html','<div>abc</div>')
      else
        return elem
      end
    end,
  }
}

but that only gets rid of {{helloworld}}, it doesn't replace it with anything. Sadly this doens't work for "==", i.e. those don't disappear.

But I can't even figure out where I'm meant to put my own text?

How do I rpelace == with " "?

Thanks!

I just tried that, thanks! That works :) But this doesn't appear to work 
for characters, like "==" which was the original goal. Am I missing some 
sort of escape characters?

Barring that, can't I use something like "> = string.gsub("Hello banana", 
"banana", "Lua user")", if so how would I do that? I got that example from 
http://lua-users.org/wiki/StringLibraryTutorial

I've narrowed it down! The issue isn't the characters but that they're 
technically "part" of the word. How do I replace PART of a word?
Thanks!

```

The problematic line is this: return pandoc.RawBlock('html','<div>abc</div>')
This adds a raw block that will only come in to effect when your output format is html.

If your target ist latex, you’ll need something like this: return pandoc.RawBlock('latex','\\whatever{abc}')

```cmd
pandoc test.md -L filter.lua -t latex
asf

\whatever{abc}

asf

Re: How do I replace a string in all text that pandoc converts, i.e. how do I do this with a filter?

[-]

[-- Attachment #1.1: Type: text/plain, Size: 9793 bytes --]

OK, so I have markdown text that includes ==highlighted== words like that. 
I would like to convert ==highlighting== either to \hl{highlighting} so 
LaTeX can handle it, or to highlighting, i.e. remove the symbols, so that 
they just don't appear.

Thanks to you, I now have a working filter that looks like this:

return {
  {
    Str = function (elem)
      if elem.text == "highlighting" then
        return pandoc.Emph {pandoc.Str "highlighting"}
      else
        return elem
      end
    end,
  }
}

This filter takes all instances of highlighting and turns them into 
*highlighting*. However, ONLY if that's a whole word. If it's 
==highlighting== it doesn't touch it because that's seemingly technically 
another word as it contains other characters. In my case I would like to 
replace only the "==" but since they're attached to other characters, i.e. 
the actual word, the filter doesn't touch them.

That's where I'm at right now. I'm now looking for a modification of that 
filter so it also applies to parts of a word.
Any ideas on that?

Thanks!

Re: How do I replace a string in all text that pandoc converts, i.e. how do I do this with a filter?

[-]

[-- Attachment #1.1: Type: text/plain, Size: 10557 bytes --]

IT HAS BEEN SOLVED :)
Using the lua.filter here: 
https://gist.github.com/tarleb/a0646da1834318d4f71a780edaf9f870 and this 
filter:
function Span (span) 
 if span.classes:includes 'mark' then 
 return {pandoc.RawInline('latex', '\\hl{')} .. span.content .. 
{pandoc.RawInline('latex', '}')
} 
end 
end
And now it works, but only because I updated pandoc. In the version that 
Linux Mint's repo had it wouldn't work.
