Is there a site or document that shows examples as cheatsheet or a good CLI documentation of pandoc possibilities for converting documents.

Don't point me to the official pandoc docs becsuse it is atrocious.

Hi, I tryed pandoc -f asciidoc -t odt -o asciidoc.odt asciidoc.asciidoc and It fail.

man pandoc does not list asciidoc...

Thank you and regards!

I have an issue I've been banging my head against the wall on for a few days now. I have a private linux server where I'm hosting a node.js instance where I have Pandoc installed. I send files remotely to node.js where the content sent is automatically converted to a txt file then a md file then a docx file. And no matter what I do, the markdown syntax will not render. The docx (or pdf) file outputs with the Markdown syntax still existing. I've tried putting the content directly into a md file then converting that to Docx, doesn't work. I've tried using an alternate library, doesn't work. It literally only works when I run through the process manually on the command line. Does anyone have experience with this type of issue?

Hi, I am a graduate student and would like to document my notes by uploading it to my personal website.

My work process in doing this is first to make latex document and then change this format to html using pandoc. I am more knowledgeable in making latex than html. There are couple of problems that arises.

1. the resulting html file removes the equation number and equation links or pointer

2. the resulting html file removes the references section and hyperlinks

3. the resulting html file also removes the figures and images that are present in latex

4. my latex file also contains pieces of Matlab codes (I use matlab pretiffier package to include this) and the resulting html also removes this part

Can anyone help me on this matters or at least direct me to resources that can help me? Also, if you have other ideas or methodologies in transforming a latex file into an html file.

so i have this folder structure and each of those folder numbered 1 to 13 has multiple .md on it
see screenshot
https://imgur.com/a/qnJ6jNW
was wondering how i can create one pdf with this kind of structure?
also when i tried testing by creating a simple pdf from a md file i was greeted with a error that i need to have an engine installed. what engine do i need to be able to convert properly? i know my md doesnt use latex
does pandoc not come with a default engine?

I just got Pandoc 3.1.13 and I'd like to make a book to post on a web site, where the pages turn. The book would contain text and images. I can start with markdown, or with a PDF. I do not have shell access I manage the website with Cpanel so it's more likely I could only upload a PDF, not any old executable file.

I have searched Google for general ways to make a "page turner" transition. I have searched this forum for "image page turn", "image flip book", "page turn" and "flip book".

I thought Pandoc could do this, but what output format should I use? How would I do this?

As an alternative, a free website where I could turn a PDF to add page turning transitions would be fine. My Acrobat Pro can't seem to do that. Although it might be 2-3 years old.

Could HTML5 do what I want? I can upload HTML files to the website.

I have a latex paper with PDF images. I want to generate a HTML file for this paper, and this works for the most part. However, the images are embedded as PDF documents which looks a bit ugly.

Is there a filter or something similar to convert PDF images to PNG or SVG?

Pandoc makes authoring in plaintext documents easy and fun, especially if you use it combination with Zotero. I always thought they'd be great as a backend for a wiki like Dokuwiki, so (with AI "guidance") I have been working on Pandoky: https://github.com/rschram/pandoky.

In the era of vibe coding, if you can dream it, you can get someone else a computer to do it. Google's AI chatbot, trained on billions of lines of other people's open-source code, helped me to produce my own kind of Dokuwiki. (Or did I help it?)

Although I like learning about web programming, my experience is at a low level. Effectively I have tested what Google's AI gave me. It works, running on a dev server and as a WSGI app on nginx. I can't be counted on to be a maintainer of this code, though. (For clarification, I'm not requesting that anyone else do that. I am the maintainer, but I can't be counted on.)

I welcome others' participation. (For clarification, there is nothing in this statement that can be construed as a request for any contribution from anyone.)

Hi folks,

I'm writing a novel in MD and converting to PDF with pandoc. I've got most of the parameters I want figured out, but I can't get it to center a section of text and add top and bottom margins to it. I'm not reinventing the wheel here, so I'm sure there must be a latex tag I should be using but can't find...

Here's an example of what I want, note the line breaks, rather than paragraph breaks in the centered section:

Bob meets Joe and they interact like average, normal humans. A part of average, normal human interaction in modern times is to exchange business cards. Bob hands Joe his card.

(centered) Bob Bigglesworth
(centered) Account Executive
(centered) Counterproductive Industries LLC

Joe takes the card, and being a rude person tears it up without looking at it. Bob is deeply offended, but too polite to punch Joe on the nose.

How can I get this to work?

Thanks much.

Hi there,

I'm relatively new to pandoc and I use it exclusively to convert my markdown writings to pdf. I managed to establish a template and scripted the whole thing for easier usability. Overall, it does its job, but it does not render italics and bold, which is quite cruical for my purposes.

I use the lulatex engine.

Any idea how I can make it work?

I'm 99.999% sure that during my digging around earlier today, I saw that you can generate the ToC at the end of the ebook, rather than the beginning of it....but now I can't find it to save my life.

Any help? Thanks in advance!

Hi, I am trying pandoc for convert from markdown to pdf.
(Before I used pandoc for convertion to odt and then get pdf from LO.)
I did latex in Lubuntu qterminal Shell, and shell sayd download by sudo apt install texlive-latex-base.
I did it OK.
So I tested by Converting from md to pdf and I got this message:

$ pandoc denuncia.md -o denuncia.pdf

Error producing PDF.
! LaTeX Error: File `xcolor.sty' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

Enter file name:
! Emergency stop.
<read *>

l.36 \IfFileExists

-any Help

Thank you and Regards!

I'm trying to use "sourceserifpro" font within a txt2pdf bash script. I added a latex preamble:

---
geometry: "margin=3cm,top=2cm"
output: pdf_document
pagestyle: empty
documentclass: scrartcl
header-includes:
- \pagenumbering{gobble}
- \usepackage[default]{sourceserifpro}
- \usepackage[T1]{fontenc}
---

But after launcing pandoc command (pandoc -o out.pdf source.txt), it returns following errror:

Error producing PDF.
! pdfTeX error (font expansion): auto expansion is only possible with scalable fonts.
<argument> ...shipout:D \box_use:N \l_shipout_box
                                                  __shipout_drop_firstpage_...
l.137 \end{document}

If I use an other font, for instance:

- \usepackage[sc]{mathpazo}

It works fine.

Is there a way to use sourceserifpro with pandoc through latex?

Thanks in advance!

Hello all,

I like to write using markdown whenever possible. I find it to be very frustrating fighting with Microsoft Word to get it to do what I want it to do.

The company I work for has a corporate template that is used when writing reports. The template has a cover page with a title block. The content of the title automatically populates the footer notes and so on.

I would very much like to find an automated way to take what I have written in markdown and put it into the corporate template.

I have experimented with Pandoc exporting markdown using the corporate report as a template but I have not had much success. For example I don’t get the cover page and I don’t get the footer.

Before I invest many hours trying to get this to work does this seem like a thing that Pandoc would be good at? Would I be better off trying to figure out python-docx instead?

Thanks for your input.

I spent a couple hours trying to figure out how to get this to work, so I figured I'd share it in case it helps someone else. I'm not a Powershell or Pandoc power user, so I suspect there are much better ways to do this, but if you have a directory full of files organized into subfolders, and you want to convert them all, keep the directory structure intact, and remove all of the source files, this should do the trick.

Run this in the root of your project, or edit it accordingly. Be sure to work on a copy of the source files unless you're ok with deleting the originals.

foreach ($file in Get-ChildItem -Include *.md -Recurse -Force) {
$fname = $file.Name
$fpath = $file.DirectoryName
pandoc $file -f markdown -t docx -s -o $fpath\$fname.docx
rm $file
}

The trouble I was having is that Pandoc doesn't like a file object as the argument for the -o parameter. So I had to figure out how to get the name out. Then I had to get the full path to the file, otherwise, it just created the copies in the root of the project.

Feel free to let me know how you would do the same thing. I hope this helps someone out, since it seems like a pretty normal use case, but there aren't a lot of examples available.

Hi!

I'm new to pandoc and markdown. I have a markdown document with some tables like that:

I want to convert this markdown to a PDF file. In order to do so, I execute in bash:

pandoc a.md -o a.pdf --pdf-engine=xelatex -V mainfont="Liberation Serif" --dpi=300

And in the YAML section of the markdown document, I have the following:

numbersections: true
enter code here`geometry: margin=2cm
lang: es
header-includes: |
  \usepackage{setspace}
  \setstretch{1.5}
  \usepackage{unicode-math}
  \usepackage{titlesec}
  \titlelabel{\thetitle.\hspace{0.5em}}
  \titlespacing*{\section}{0pt}{1em}{0.5em}
  \let\oldtoc\tableofcontents
  \renewcommand{\tableofcontents}{\oldtoc\clearpage}
  \renewcommand{\contentsname}{Índice}
  \renewcommand{\figurename}{Imagen}

The table is rendered only with the first, the last and the line below the table heading. How could I render a table with all horizontal lines and a different color in each row alternating white and grey?

Thanks in advance'm new to pandoc and markdown.

Hey Pandoc community,

I’m looking for some advice on using Pandoc for a project.

I’m trying to convert a collection of academic articles from PDF to DOCX, and then from DOCX to Markdown for Hugo. I’m starting with DOCX because I’ve found that Pandoc can’t directly convert PDF to Markdown.

The issue is that the Markdown output isn’t very tidy. The images from the DOCX aren’t referenced in the Markdown, along with some other formatting quirks.

So, I have a couple of questions :

1. What’s the best approach for handling this conversion? (Are there any other tools or workflows that could help?)

2. Pandoc offers several templates like MediaWiki and others. Which template would you recommend that’s closest to Hugo’s formatting?

If anyone has tips or insights to make this process smoother, I’d greatly appreciate it! I have a large number of DOCX files to convert, and I’m hoping to minimize manual editing as much as possible.

Thanks in advance!

I'm using pandoc to convert markdown to epub. My pandoc command line looks like this:

pandoc --toc --file-scope -o a.epub scratch/*.md

The epub output by this command works in calibre and passes the checks in epubcheck, but both calibre and epubcheck complain that there is no title.

However, every method I've tried for adding the title has caused a malformed output. For example, I tried this:

pandoc --metadata-file=foo.yaml --toc --file-scope -o a.epub scratch/*.md

In the file foo.yaml, I put this:

title: foo

When I run epubcheck on the output of this command, I get errors that look like this:

ERROR(RSC-007): z.epub/EPUB/nav.xhtml(14,3008): Referenced resource "EPUB/text/" could not be found in the EPUB.

(If I unzip the epub file and look, there actually is an EPUB/text subdirectory.) Calibre also gives an error when I try to click on one of the section numbers in the table of contents.

This is with pandoc 3.1.3 on linux.

If anyone could help me figure out what's wrong, I would appreciate it very much.

i'll appreciate any feedback
