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!On Tuesday, December 6, 2022 at 11:00:09 a.m. UTC+1 denis...@unibe.ch wrote:Sorry, I haven’t been following from the beginning.

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!

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 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?

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:

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')
else
return elem
end
end,
}
}

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
```

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

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!
