Pandoc 1016 points by otp124 3 months ago | hide | past | web | favorite | 204 comments

 I do all of my academic writing in pandoc. As compared to LaTeX this means no boilerplate (yet you can still use full LaTeX syntax for equations and the like) and, if the publisher 'needs' a Word file, you are one click away from providing it. All with plain text files that you can put under version control, get meaningful diffs, etc. It's just great.
 Sorry to be pedantic - but I didn't think that 'pandoc' was an actual document format purely a tool for converting between formats. Do you mean that you do your writing in kind of a 'pandoc flavoured' markdown? [0]
 Well, between Pandoc's markdown flavor and how it has its own way of letting you insert latex code anywhere, you're not going to be able to process your document using anything that's not trying to be compatible with pandoc documents.
 I’ve never understood the impetus for not using full LaTeX in an academic contex, given that the boiler plate is so minimal and presumably one has a built up a personal template over time.For blog posts and notes I see the appeal, since the boilerplate can be a hindrance to spontaneous writing.
 Latex can't produce web output, which is increasingly a target I want.Also, Latex can't produce any output which is accessible to blind people (other than giving them the raw LaTeX). The PDFs latex produces are probably the least accessible format available (much worse than a word proeuced pdf, or some html). This matters to me, and should matter more to other people (in my opinion).
 BUT that is what makes Pandoc powerful. You convert your latex or your whatever into: (Can we please add Racket's Scribble? It is by far the reason why Racket has the best documentation of any language. https://docs.racket-lang.org/scribble/)Markdown, reStructuredText, textile, HTML, DocBook, LaTeX, MediaWiki markup, TWiki markup, TikiWiki markup, Creole 1.0, Vimwiki markup, OPML, Emacs Org-Mode, Emacs Muse, txt2tags, Microsoft Word docx, LibreOffice ODT, EPUB, or Haddock markup toHTML formats XHTML, HTML5, and HTML slide shows using Slidy, reveal.js, Slideous, S5, or DZSlides Word processor formats Microsoft Word docx, OpenOffice/LibreOffice ODT, OpenDocument XML, Microsoft PowerPoint.

 Well, except LaTeX probably isn't the best base format to write in -- Pandoc's LaTeX parser isn't very good, it doesn't parse (from a quick check) any of the papers I've written. They've tried hard, but I think it's a losing battle, particularly once people start using a large range of packages.That's not surprising -- it's basically impossible to "parse" LaTeX, as it's defined by execution.
 iirc pandoc's markdown provides the set of functionality that one is capable of transforming back and forth. So as long as you stay within those formatting confines, you are set.This works for everything except table notes a la threeparttable
 What about htlatex? It is quite powerful. In most of the cases, it produces nice HTML pages out of the box, with automatic rendering of figures and mathematical equations into PNG. It is part of most LaTeX distributions. On Linux, for example, just type $htlatex mydoc.tex  instead of$ pdflatex mydoc.tex
 For me, at least, htlatex never works just quite right. There are a lot of edge cases where it's broken. If you want to preserve having non-PDF output, starting in something like Pandoc Markdown is a better idea. And I do most of my documents in regular LaTeX.
 >Also, Latex can't produce any output which is accessible to blind peopleThis sounds like it should definitely be a target of a grant. I guess most government organisations around the world are using Word et al, which isn't too bad these days accessibility wise (AFAIK).Can you provide a small example of a LateX document that produces an inaccessible PDF?
 If you grab any academic paper (particularly two columns) there is a good chance getting the text out will be hard, and any part of the paper with maths or tables will be unusable. Sorry. I'm away from a computer now, to make a smaller example.
 The paper "GADTs Meet Their Match" (first I had in my list) seems to work fine, but I don't know what it was generated with.
 cairo 1.13.1 is listed as the generator.http://checkers.eiii.eu/en/pdfcheck/?url=https%3A%2F%2Fwww.m...The ACM template fails more! http://checkers.eiii.eu/en/pdfcheck/?url=https://www.acm.org..., and it's generated by pdfTex-1.40.15
 I'll pick on one of my own random papers:https://www.cs.york.ac.uk/aig/projects/implied/docs/cp03.pdfTry extracting "Theorem 2" on page 5, or any text really. I just get random noise through either a PDF reader, or something like pdf2ascii / ps2ascii.We just made this with standard latex.
 Any chance you could post the source code for this? It's using bitmaps for characters instead of proper fonts, which shouldn't happen nowadays. Maybe you should put "\usepackage{lmodern}" at the start? See for example https://tex.stackexchange.com/questions/1291/why-are-bitmap-...I work with course materials made in Latex, and students sometimes need/want to copy and paste from them, so I try to avoid these kinds of problems.
 That’s interesting. Did you \usepackage[T1]{fontenc}?
 Thanks paper is from 2003, so I'm not sure.This is just an example. From experience, most PDFs at conferences and journals, generated from pdf, are not accessible to varying degrees.
 Accessibility is a big current push from the TeX Users Group. The president, Boris Veytsman, has made moving it forward a big goal. I know that a lot of people are working on aspects of that, but the name I hear the most is Ross Moore, who I have heard talk on making the output be PDF/A-3a compliant. I understood that it is a long way there.
 I hope so, because honestly, Tex generated PDFs are the single biggest problem with being a blind researcher (I'm not blind, but I know a blind researcher).
 >I’ve never understood the impetus for not using full LaTeX in an academic contex, given that the boiler plate is so minimal and presumably one has a built up a personal template over time.I don't find the boilerplate minimal at all. Contrast the following: \begin{itemize} \item First \item Second \item Third \end{itemize}  with - First - Second - Third  I won't even get into the hell that is tables.I loved LaTeX until I discovered Org Mode. Pandoc also scratches the same itch.
 I agree. If one is going to use LaTeX directly or indirectly via Pandoc, eventually one would have to build up a personal template to fine-tune the look and feel of the documents.If one is going to write LaTeX code anyway, it seems easier and cleaner to use LaTeX all the way, move all the boilerplate along with the personal template to say, a file named preamble.tex, and \input{preamble.tex} in the documents.However, there are situations where Pandoc can be convenient. For example, I wanted a document[1] to be written primarily as README.md (CommonMark format), so that GitHub could render it as the project README. At the same time I wanted to render a PDF output from a customized form of the content. Pandoc is convenient for cases like this although it takes a bit of work to fine-tune the formatting and customize the content for each output format.
 >If one is going to write LaTeX code anyway, it seems easier and cleaner to use LaTeX all the way, move all the boilerplate along with the personal template to say, a file named preamble.tex, and \input{preamble.tex} in the documents.Not sure why you think it has to be that way. I author LaTeX documents using org mode. Org mode handles most of the boilerplate, and I can still put pretty much any custom LaTeX within the org document, wherever I want it (this includes \newcommand, etc). I lose nothing by going to org mode, and I gain much in terms of reduced boilerplate.
 Yup. I’ve got a pandoc template for doing org-latex-pdf conversion, as well as some org templates for common documents that my clients need. Hack away on the document in org (which I’m probably going to be doing anyway, since the rest of my life is in there too), and then when it’s ready to hand off, turn it into a PDF using a shell script.My absolute favourite moment with that flow was a client who wanted one as a docx instead of a PDF. Pandoc obliged and they commented that I must have spent a lot of time reformatting things for them :)
 Why not use Org's built-in org->latex->pdf exporter? AFAIK Pandoc isn't compatible with many of the more interesting Org features, such as Babel.
 That's a good question! The flow started out as markdown->latex->pdf via pandoc, and then when I got back into Org, it just slid right into that workflow to replace Markdown.I'm curious now though... maybe I'm missing out!
 It isn't clear to me whether you are saying that Pandoc is necessary or if you are saying that Pandoc is unnecessary and LaTeX alone is sufficient for all purposes.I think your parent comment was saying that LaTeX alone is sufficient. You also seem to be saying that LaTeX alone is sufficient while using Org mode. Would you please clarify if I am interpreting your comment correctly or not?
 >It isn't clear to me whether you are saying that Pandoc is necessary or if you are saying that Pandoc is unnecessary and LaTeX alone is sufficient for all purposes.I'm not saying either. The parent said it's easier and cleaner to use LaTeX all the way. I was pointing out that it is easier to write in a format like Org mode and export to LaTeX (whether via Pandoc or Org mode's built-in exporter).Of course LaTeX is "sufficient". It is also, IMO, painful.
 Pretty sure they are saying pandoc is unnecessary.
 I wrote my dissertation using Pandoc. It might seem that the LaTeX boilerplate is minimal, but Markdown is even more minimal, and it preempts the urge to fuss with your layout. Writing in Markdown means that you can wave your hand at the document and say, "It's a draft, I'll fix the formatting once I'm sure I even want this material." Afterwards, fixing the layout is really easy because you can drop raw LaTeX in wherever you need to, and you haven't wasted countless hours laying out a float you later end up cutting.
 Having to use \textbf{...} is impetus enough for writing in Markdown instead.
 LaTeX editors have simple keybindings for this, like ctl-b., or C-c C-f C-b in emacs, which makes this kind of thing a non-issue for me...
 Just reading C-c C-f C-b is an issue for me and I haven't even tried to remember and type it yet.
 C-c C-f is a prefix key, you get bold with C-b, italic with C-i and so on. At least it was last time I used AucTex :)
 I agree - while pandoc is great it's usually not 'one click' to any format, especially when have html or latex-specific markups.It's not for everyone, but emacs+auctex really reduces the latex boilerplate (at least writing it) that I don't really feel it's a hindrance.
 I didn't use LaTex for years, is it still a hell to make tables? And also very difficult to use templates to generate good looking documents that doesn't like an academic paper?
 Yes! It's great to be able to put LaTeX-formatted equations directly into your pandoc-flavored markdown source file.Incidentally, I really like the thoughtful syntax additions Pandoc makes over olde Markdown (eg., tables, definition lists, and span & div syntax as well). Such a great all-around doc tool.
 What's your workflow for inserting and managing references
 Not OP, but I used +citations and pandoc-citeproc along with a bibtex file that I managed by hand for https://bernsteinbear.com/dat-paper/ (a small senior project paper). It worked pretty well for me.
 Add bibliography=path/to/library.bib (and optionally specify a csl for bibliography formatting; I like econometrica) in frontmatter yaml. Insert citations with @bibcitekey. compile with --pandoc-citeproc filter.
 It was a couple of years ago that I wrote my dissertation using Pandoc, so things may have changed. At the time, I started out using pandoc-citeproc with my BibTeX database, but eventually I needed more control over formatting and I switched to writing \cite everywhere. Even with hundreds of references, it only took an afternoon, so I'm happy I did it the way I did. My approach with Pandoc is to use it until you have to invest LaTeX-level effort into making it do what you want. At that point, swapping in LaTeX is rarely painful. Often you can get away with editing Pandoc's generated LaTeX and pasting it back in to your source.
 You can control the formatting pandoc-citeproc (which is now built in to pandoc) produces with a CSL file. That's great if your institution provides one, otherwise... you'll have to learn CSL ;-/
 I use pandoc-crossref.
 > if the publisher 'needs' a Word file, you are one click away from providing itOnce the work has moved into a Word file, isn't that where it stays? Editors and publishers often make heavy use of features like track changes and notes. Doesn't pandoc lose that information?
 It does. I think the assumption here is that the author is the only contributor to the document. Exporting into a Word doc would serve the same function as exporting to a .pdf, others could read it and even mark it up, but the author would have to make the noted changes in their original plain text document themselves.
 pandoc has a --track-changes option, so you can convert a docx file with its proposed changes back to, say, markdown.
 I tried and it didn't work for me. Pandoc's conversion functionality is good but unfortunately also fails very often, at least in my experience. I suppose with custom templates and a lot of trickery I could get it working for the kind of papers I write, but I've found it easier to convert LaTeX to Word manually when needed - which is a pain in the ass, too, of course.
 In my experience it works so long as you keep to very vanilla LaTeX code. Pandoc's support for LaTeX packages tends to be very patchy.
 I have to put in a word for Racket's Scribble. Programmiclly creating documents is powerful, and this system makes it simple. You can also basically use it as a "Markup-less" system.Scribble Code Example:#lang scribble/base@title{On the Cookie-Eating Habits of Mice}If you give a mouse a cookie, he's going to ask for a glass of milk.@section{The Consequences of Milk}That squeak'' was the mouse asking for milk. Let's suppose that you give him some in a big glass.He's a small mouse. The glass is too big---way too big. So, he'll probably ask you for a straw. You might as well give it to him.@section{Not the Last Straw}For now, to handle the milk moustache, it's enough to give him a napkin. But it doesn't end there... oh, no.Scribble -Scribble is a collection of tools for creating prose documents—papers, books, library documentation, etc.—in HTML or PDF (via Latex) form. More generally, Scribble helps you write programs that are rich in textual content, whether the content is prose to be typeset or any other form of text to be generated programmatically. - https://docs.racket-lang.org/scribble/Some languages based on ScribbleSkribilo -Skribilo is a free document production tool that takes a structured document representation as its input and renders that document in a variety of output formats: HTML and Info for on-line browsing, and Lout and LaTeX for high-quality hard copies.The input document can use Skribilo's markup language to provide information about the document's structure, which is similar to HTML or LaTeX and does not require expertise. Alternatively, it can use a simpler, “markup-less” format that borrows from Emacs' outline mode and from other conventions used in emails, Usenet and text. https://www.nongnu.org/skribilo/Pollen -Pollen is a publishing system built on top of Scribble and Racket. So far, I’ve optimized Pollen for web-based books, because that’s mainly what I use it for. But it can be used for small projects too, and non-webby things like PDF.As a publishing system, Pollen includes: A programming language. The Pollen language is a variant of Scribble, with specific dialects tailored to different kinds of source files. You don’t need to use the programming features to do useful work, but they’re available when you need them. A set of tools & libraries. Pollen can produce output in any format, but it’s especially useful for markup-style formats like XML and HTML. A development environment. Pollen works with the DrRacket IDE. It also includes a project web server so you can dynamically preview and revise your publication. http://docs.racket-lang.org/pollen/Backstory.html  They are Domain Specific languages that excel at outputting awesome HTML and PDF. They really aren't markup but really they are a Macro system that is built on top of a full Lisp (Racket) It is easier and much more powerful then anything I have seen on Pandoc and Latex (I use Latex still for specific targets but not for general papers anymore).Racket has the best documentation period and it is because the documentation

 everytime I see a project using google groups, i think it is already dead. Gladly yours seems to be used quite often. At least you can search it even years later, compared to an irc or slack channel.
 IRC channels and mailing list are excellent for informal questioning about a project. You can search for guidance, see if a feature would be well received, and receive a green light before starting to implement something.Other day I thought about contributing to Yarn, the Javascript package manager, but the only way that I found to communicate with the developers were issues in GitHub. Since I didn't know if the feature I wanted would be well received, I just quit.
 That seems a little bit extreme, why not just open the issue?
 that issue becomes part of public history.i'm not the parent, but that is the main reason i try to abstain from posting on public forums unless its under a pseudonym, which my github account isn't.I'm not trying to say that my anonymity is guaranteed with irc, its just unlikely that future employers and similar link it to me.
 Have a look at Firefox Multi-Account Containers. You can open a tab that has a different color, and it uses a different cookie database. Very useful, because you can create an extra Github account and quickly switch between those accounts.
 Agree. That's probably one of tje reasons why HN is so interesting:Requiring everyone to sign in with full, verified name limits what people can talk about.In fact I'd almost recommend against commenting online on anything using your full name.
 Aren't mailing lists even older than IRC? Anyway, whatever works, right?
 Heh, not quite. Go (the programming language) uses Google Groups (golang-nuts and golang-dev), and it's very alive.
 Hey, just a one-time contributor here (fixed a small bug in the wikitext parser), I have to say that the community is really, really great! I had never done any haskell before, but with just a little guidance from the IRC channel (#pandoc on freenode), I was put on the right track and submitted my small PR, which was merged quickly.Overall great experience. Thanks for the great tool :).
 Could we consider Pandoc a rough replacement for leanpub publishing tools?
 Probably. I'm not too familiar with leanpub, but seems like they're actually using pandoc to import docx.[0] And with pandoc you can also export to epub, pdf, docx, indesign, etc.
 My favorite pandoc hack is using it to convert word docs into markdown which can then be diffed similar to source code. Works great for legal redlining.
 Agree, and it can be nicely integrated with Git: http://blog.martinfenner.org/2014/08/25/using-microsoft-word...
 Do Word’s native diff features not work for you?
 Can you diff two Word docs with Word? Afaik you can only hit the "track changes" button, which doesn't help if you got a new version of a document from someone else.
 Tools, Track Changes, Compare Documents ...https://support.office.com/en-us/article/compare-and-merge-t...Had this forever, here's a visual on old version of Word:http://www.techyard.net/how-to-compare-two-word-documents-an...For more advanced, try legal blacklining:https://support.office.com/en-us/article/compare-document-di...Or combine multiple sources of a similar document:
 None of that is version control. At best that's a visual based manual patch file tool.That you can't concat two word files together in 2018 is ridiculous.
 > That you can’t concat two word filesOf course you can!# cat word1.doc word2.doc > word3.docSounds ludicrous? So does your statement.Setting aside the hyperbole, I believe it would be a conceptual nightmare to start defining concat of two docs. For simple cases, feel free to make copy pasta :-)
 > I believe it would be a conceptual nightmare to start defining concat of two docs.Just append the pages of document 2 to the end of document 1. Then the user can decide whether to remove the page break introduced by it. I have this in my env for doing this with PDF: $cat =concatpdf #!/bin/bash if [ "$1" = "to" ]; then shift gs -q -sPAPERSIZE=letter -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=$* else echo Usage: concatpdf to out.pdf in.pdf in2.pdf in3.pdf fi  The peculiar syntax with "to" ensures that I do not invocate it incorrectly.  $ pandoc file1.md file2.md -o file.docx  Tada, I two files into one word file.It isn't difficult. TeX and LaTeX have been doing it since the 70s and 80s respectively.
 Yes, and you can merge changes too.Classic Word workflow: I make a document and send it to my boss; he makes some changes but suggests further research etc. and sends me his altered version, but I stupidly work on my own version. Making this right takes like four clicks.
 Syncdocs [0] is also pretty good for merging and tracking changes between Word and Google Docs. It also has a feature with real-time collaboration between Google Docs and Word.
 I have been searching for this for a long time and not able to achieve it without resorting to manual copy and paste from one doc to the other.This sounds like utopia. :-) Do you have a link to a page that outlines these steps?
 It works if you don't change formatting, don't edit the same section, don't rearrange chapters and don't have lots of changes or a large document. You do any of that, and the application crashes.It's good for a small fix, but not something to rely upon in your main documentation workflow.
 Even if you can do it with Word, GUI interactions aren't composable and extensible the way shell commands are, so you're limited to the features the GUI designer thought of.
 >GUI interactions aren't composable and extensible the way shell commands areThey might not be in word, but they absolutely can be, and in fact are a superset of CLI interactions (since a GUI interaction step in e.g. Automator can invoke any shell command).>so you're limited to the features the GUI designer thought ofAnd in the traditional shell pipeline (that is, not Powershell) I'm limited to working on dumb streams from one command to another.
 Completely new to this: so you're highlighting the differences between two documents in word? say 2 terms of service 1 old and 1 new?
 Yes
 Hmmm. Wonder what "track changes" does if you Ctrl-A highlight the entire old doc, and paste the entire new doc over it.(I imagine it registers it as one huge change, rather than tracking a zillion individual changes, but it might be interesting to try.)
 It does exactly that. I don't know why someone downvoted you for that comment.
 Diff works great in Word.
 Another option I recommend comparing two Word docs (and just about anything) is Beyond Compare.[0]It's the software you would have to buy, but if you have to compare files a lot I would highly recommend it. (Runs on multiple platforms, too.)
 WinMerge does the same, and it's open source. It's only for Windows, though.
 Yeah, WinMerge a nice tool, too.Aside from multi platform, BC has things like CSV compare and marking unimportant changes are fairly robust. I do personally prefer open source myself, but BC is certainly one of the few that I didn't mind paying for.
 Trying pandoc on a word doc gives me: # pandoc test.doc -o test.pdf pandoc: Unknown reader: doc Pandoc can convert from DOCX, but not from DOC.
 As the error says, pandoc doesn't support .doc files, only .docx.
 Ok, but then they shouldn't call the tool pandoc.
 Get out :P
 Does it come up with the right semantic content for lists and tables?
 > legal redliningIs this underlining, and not redlining as defined in financial services? (redlining: differential pricing based on demographic makeup of a zip code or neighborhood)
 Attorneys and business folks use it to mean “marked up” - a redlined contract has additions in red, and removals in red with red lines through them.
 Redline as in how strikethrough appears in Word. It's a colloquial term.
 OP was referring to diffing changes between the original and modified version of a legal document (typically a contract).
 I use Pandoc to convert directories of Markdown files into static HTML websites.Here's the build command for responsive.style[1]: pandoc $file -f markdown -t html5 -H templates/header-prod.html -B templates/nav.html -A templates/footer-prod.html -o (echo "../$file" | sed '$s/\.md$/.html/') -s --data-dir=./ --highlight-style breezedark --variable=file:(echo "$file" | sed '$s/\.md$/.html/')  Works beautifully!  Nice.I wrote up a tool as well, with navigation and prev/next links: http://www.unexpected-vortices.com/sw/rippledoc/index.html  I know Blot.im as one static site generator that uses it: https://github.com/davidmerfield/Blot/blob/master/app/models...  Hakyll is another: https://jaspervdj.be/hakyll/  Another happy Pandoc user here :)I built a pipeline to convert a Markdown file to publishing-ready files for ebooks, Kindle and paperback for my novel; the whole thing is described here: http://www.gabrielgambetta.com/tgl_open_source.htmlMy website itself is static, generated from a bunch of Markdown files, some HTML templates, and a bit of postprocessing. But most of the work is done by Pandoc.  Hey. Can you give us some more context of your novel writing in Markdown? I'd be interested in your process.  Sure. The technical side of things is explained here: http://www.gabrielgambetta.com/tgl_open_source.html (same link as above). If you're more interested in the creative aspect, I wrote a bit here: http://www.gabrielgambetta.com/tgl_swiss_trains.html. If you're interested in anything not covered there, feel free to ask, I'll be happy to share :)  "Soon the structure underlying The Da Vinci Code and Angels and Demons and The Lost Symbol was laying bare before my eyes. I could see why the stories worked.I had reverse-engineered Dan Brown."Could you talk a little more in depth about what Dan Brown's pattern/structure is?  I get that request a lot, so I'll have to write something about it :)All I can offer right now is my raw notes, which are in Spanish. This is a structural analysis of Angels and Demons, The da Vinci Code, and The Lost Symbol: https://imgur.com/bX6ByJAThis is an one-page treatment of the three books, with the "blanks" filled appropriately for each: https://imgur.com/LlDVUKnI doubt any of this is groundbreaking. Story structure is a widely studied topic (and one that I find fascinating). But it seems like Dan Brown uses a very well defined, customised version of this, that makes for engaging, fast-paced books.I sort of proved (for myself, at least) that this works, by writing a novel whose structure was originally based on this pattern (although it later diverged a bit), and which causes the expected effect - a couple of readers have read it in a single sitting :)  Very interesting! Could you maybe provide those links in text form, so that we may run them through Google Translate? ;-)  Sure, good idea - https://docs.google.com/spreadsheets/d/1HdlD_tmmm1D0zX1JgXzF...  English translation done!  Thanks for the second link! This is exactly what I meant.EDIT One more question. How do you write dialogues in MD?  Maybe I'm misunderstanding your question, but there's nothing special about dialogue in MD. Quotation marks, inner thoughts in italics. "It's just some text between quotation marks", Gabriel typed. *Have I completely misunderstood his question?*  No, that's exactly that. Thank you!  The one thing it can't do is give HN posts descriptive titles.  Thanks, this made me chuckle. Its comments like these which make HN a bit more colorful :-)  Also, interesting point of trivia, the maintainer, John MacFarlane is a professor of logical philosophy at UC Berkeley.  One nice trick that I use all the time is to convert html to md and back again in order to clean it.Anyway, pandoc is great.  Would that be a good way to sanitise user input? Like removing script tags etc...  It’s usually not a good idea to “get creative” when it comes to security  Only if you trust Pandoc enough to expose it to unsanitised user input.  It appears that Pandoc generates PDF documents via LaTeX. One problem with this is that, as far as I can tell, LaTeX can't generate tagged PDFs. This is an accessibility problem. Granted, for documents that are heavy on math and/or graphics, the point is probably moot. But many technical documents that are distributed as PDFs would benefit from being tagged.Luckily, LibreOffice can produce tagged PDFs. And unoconv is a convenient utility for doing this from the command line. So you can use pandoc to convert to a format that LibreOffice can consume, then issue a command like this: unoconv -f pdf -e UseTaggedPDF=true mydoc.odt  I've tried it, and it works.  Pandoc can convert into ConTeXt which can produce PDF/A (tagging included) easily. Why this can't be done in one command like with xelatex, wkhtml2pdf and what else is supported, I don't know. Many programs can be used to create PDFs but the quality of output isn't always the same.  > Why this can't be done in one commandConTeXt is supported as well: pandoc input.md -t context -o output.pdf  Pandoc (or latex) + make + iNotifyWait work really well together for WYSIWYG like editing too: watch:$(ALL) while true; do \ clear; \ make $(WATCH); \ inotifywait -qr -e close_write .; \ done  "make watch WATCH=build" will now compile documents on every save. Works well for single documents, collections of documents or entire websites.  I've been using a JS script[1] to watch directories, but this seems neater. Would you mind sharing the whole makefile?  I sometimes use pandoc to clean up my markdown-formatted documents, especially given its abilities to "wrap" text and add indentation-style whitespace that makes plain-text documents look nearly suitable for publishing as-is (almost kinda like RFC docs but without header/footer cruft).There are a few things (in latest version, 2.2.3.2) that don't really survive round-trip from markdown back to markdown:- reference-style links (e.g. [foo][f]). They are converted to inline links e.g. [foo](http://...).- setext vs hashmark headers. foo\n===== will get converted to # foo.- markdown allows for forced-linebreak s to be added with two trailing blank spaces at the end of a line. Pandoc escapes these with a trailing \ at the end of the line.These are only occasional nuisances, but overall the documents (at least in my experience) are not butchered.I also occasionally go from markdown to docx for the purposes of uploading to google-docs and copy/pasting large sections into other docs. This is the only markdown-to-google-docs workflow I've found that works to preserve formatting. It's never really butchered anything, except a few times the syntax-highlighting for code-blocks gets confused and keywords get the wrong colors.  IIRC, there are CLI flags for your first two points. I think the latter is something like —atx-headers.You can choose whether reference links go at the end of the paragraph or the document.  Pandoc's creator, John MacFarlane, is also the lead guy on CommonMark[1].There are a small number of corner cases that need to be spec'd out before CommonMark can declare a v1.0 release[2]. If you have the skills for this kind of thing, please weigh in!  Please, please involve definition lists. They are useful. They were present on the first webpage[1].  I wrote a little utility that uses Pandoc to read Markdown files like man pages in the terminal:https://github.com/ashton314/marked-manIt's just a one-liner: pandoc -s -t man "$1" | groff -T utf8 -man | \$PAGER(That was basically stolen from an answer to one of my questions on Stack Overflow—thanks to those who answered! :)
 In a similar vein, I use pandoc to convert markdown pages to man pages, and write new/add notes to manpages. I think it's definitely easier than actually writing groff files.
 I find it easier to write man pages directly. Admittedly, I write mdoc (not the ancient "man" macros), which has been around only since the 80s. It's easier for me to remember the semantics ("Is this a flag/command/function?") than the correct traditional markup ("Should this be bold/italic/nothing?").
 I "love" how many comments are one person praising pandoc for helping them in some workflow, and then commenters ripping into them for not using some other tool. I wonder if there's a corollary to some internet rule that the more generally useful a tool is, the more detractors will push for other tools to be used? It would help explain why programming language discussions get so contentious.Pandoc is seriously a great tool! I love the way it's designed and have found it useful off and on over the years. Truly marvelous for making information available in any needed format.
 I love pandoc. I've been using it intermittently for years to turn my Markdown and org-mode documents into other formats. Just wish it would take Asciidoc as an input format.
 Asciidoctor and the other asciidoc tools do the job that I use pandoc for: tables, custom numbering, all the other markdown extensions that one needs to be able to create a highly structured document. With Asciidoc, you don't need md extensions. It's all in there.
 Ya, I've been using Asciidoctor and Asciidoctor-pdf for long time. Those are some awesome tools, too.
 I mainly use Asciidoc for two reasons. 1) Ability to include external code snippets. This is not possible in pandoc without installing the pandoc-iclude-code filter which doesn't have Windows binaries. I am on Windows. 2) Tables. Asciidoc has powerful support for tables. You can create tables that include rowspan and colspan among other features. You can even specify an external CSV file as a table.I tried creating a workflow from Asciidoc through Pandoc to MS Word but that didn't work so well. Tables being the biggest issue.
 There is useful discussion on the issue regarding Asciidoc
 Pandoc is great software for converting among file formats, such as text, markdown, HTML, PDF, etc.Example: pandoc in.md -o out.html -V pagetitle="My Title" --to=html5 --template="my.html" --css "my.css"  The example converts a markdown file to HTML, using a given title, a template file, and a stylesheet file.The pipeline is also well implemented with Haskell, which is good for writing your own fast functional transformations.
 I write fiction as a hobby, I do it in markdown and use Pandoc to turn it into epub files with a custom CSS. It works great. Thanks Pandoc!
 Is the CSS derived from the markdown, or you supplement MD to HTML with custom CSS? Definitely curious to know!
 I used a similar workflow. The CSS is for the EPUB and maps to the html elements supported. But if you get too fancy cross device support could get hairy.
 Custom CSS. Nothing fancy, I haven't really explored what's possible with epub.
 I used pandoc to format my book [0]. Not everything worked perfectly, I'm pretty happy with how everything turned out (especially the print version).It was a little work to set up the workflow with scripts etc, but being able to write the book in markdown and still having full control over the design was definitely worth it.[0] sample here: https://patricklouys.com/professional-php-sample.pdf
 You can use the Haskell-based static site generator Hakyll with Pandoc to create the best best blogging experience imho.An example of how easy this is and the styles I use for my personal blog: https://curious.observer https://github.com/davnn/curiousobserver
 Maybe I used an older version but my attempts to use pandoc usually resulted in the document being butchered because the internal representation was not as expressive as the source or target formats.
 Pandoc is also a great educational Haskell project for those looking into how it all works.
 If you don't want to install Haskell and other dependencies, several folks have developed Docker images for using pandoc:https://users.soe.ucsc.edu/~ivo/_posts/2015-03-12-repeatable...http://gbraad.nl/blog/document-generation-using-markdown-and...
 You could also just download one of the packages from the "Installing" page on the Pandoc web site, which has prebuilt binaries for Windows, macOS, and Linux. Installing a whole Docker image to do this seems like it might be overkill for a lot of uses.
 You'd only need to install Haskell if you wanted to build Pandoc. Pandoc the executable is a binary. I install it on Debian via: apt install pandoc.
 although the version in the default repo is usually quite old. You can grab a binary from https://github.com/jgm/pandoc/releases/latest
 Bonus hint: If you somehow aren't able to upgrade the binary (enterprise...), using an up to date template helps a lot (at least for LaTeX).
 Yet another pandoc user here. I built a blog engine using Pandoc as the core. Code available here : https://github.com/subinsebastien/kyll And the website built using the blog engine is available here : http://xtel.in/
 I tried to use pandoc a while ago to convert the latex-sources of arxiv.org documents to epub, since those are often much more comfortable to read on small devices than pdfs.The problem I had was that latex was turned into images, but changing the font-size of the reader did not change the size of the images, making the text readable, but the maths barely readable.This is something I would love to see happen though.
 Take a look at arxiv vanity https://www.arxiv-vanity.com/
 > latex was turned into imagesYou can add some CSS to the generated EPUB to change that. But if your EPub reader supports MathML, you can do that with pandoc. See http://pandoc.org/epub.html#math
 I've seen this problem on Kindle books with equations, is that a related problem?
 Seems like an issue with the epub reader though?
 I like pandoc. I've been using Typora [1] for all of my writing, and it's decent, but a little slow.What editor do HN folks use? I wonder if there's a leaner editor out there with an equally nice distraction-free editing interface. Thanks in advance!
 Emacs and emacs ord mode, and then you can export to html5 latex/pdf, etc. My notes, calendar, todo, data science workbooks, etc all live in emacs org mode. Especially love the ability to call programs on the fly in my data science workbooks, so I can call R, Julia, python, and bash all in one place.
 Asking what editor HN uses is a pretty loaded question, but it looks like there's a couple neo/vim plugins for live markdown preview. This one[0] says it can use pandoc as a backend. I'm pretty sure that emacs offers something similar, and org-mode may be worth consideration all on its own. I hear spacemacs and spaceneovim are nice.

 I've been really enjoying the Caret beta -- https://caret.io/Not free, but a real pleasure to use.
 I tried Caret and loved it but had to uninstall because of the huge font size on equation renders in a math-heavy document. Is there a way to fix that? I tried to look but they don't have much documentation yet.
 Even though org-mode has its own exporters, Pandoc is great for the extra bibtex integration.
 The only problem I have with pandoc is I have to lug the entire GHC around with it.
 That is not the case.https://pandoc.org/installing.html> We provide a binary package for amd64 architecture on the download page. This provides both pandoc and pandoc-citeproc. The executables are statically linked and have no dynamic dependencies or dependencies on external data files.
 There's an unofficial Arch package for it: https://aur.archlinux.org/packages/pandoc-bin/I wish I'd known about this sooner. I don't spend much time with text documents outside the web, but when I do, pandoc handles the disparate formats admirably. The only inconvenience is when I update my system, there's guaranteed to be a huge pile of Haskell libraries to download.
 Thanks! I wonder how it was built.
 What don't I use it for?+ Static websites from any input to html+ Markdown & TeX & References to pdf for academia+ Generating manpages for new tools+ Generating ebooks... Let's just say I get a bit lost when it isn't available.
 > + Generating manpages for new toolsDo any of your tools use long options (prefixed with a double dash)? If so, make sure you disable the "smart" extension, otherwise you might end up with en dashes.
 Aye. I've got several long lists of options, depending on the project. Manpages might have been the most fiddly to get right.
 OP said he doesn't use pandoc for such things. It's a list of things that have better tooling.
 Maybe he edited his post, but it now ends with "... Let's just say I get a bit lost when it isn't available. " suggesting that he actually does use pandoc for stated tasks.
 I'm sorry if it came across that way. The list is what I use pandoc for. I use it for a lot, so much that I think I use it for every project.
 I found it confusing too. You were supposed to use interrobangs (‽) instead of "?" :)
 Would that not only be applicative if I were making an exclamation? Whilst instead, I was making a statement.
 It sounded like a rhetorical question, and based on the context that you use it for a lot of things, I sensed a bit on excitement there too, and thus the exclamation.. like "Isn't that awesome‽".
 What do you use for ebooks? Asciidoc?
 A mix. Depends on the book.For novels, I tend to just use Markdown, as kerning will be done in CSS.For academics, I use LaTeX and Asciidoc together, but some paragraphs might be inserted in various other formats - whatever is easier. The build tool doesn't care what the format is, it'll take any input pandoc accepts.
 I love pandoc, but I'm very surprised that such an established tool has (at time of writing) 865 points and is #1 on HN.I guess it's not as well-known as I thought.
 i have been using catdoc and pdftotext to convert doc and pdf files, respectively. nice to see that there's an alternative that also includes a library, will be checking this out.a couple questions i have, seems firstly that old school .doc files are not supported, docx yes. unfortunately i still get a lot of docs in .doc format which seems to be microsoft's proprietary format (docx seems to be more open).my second question is whether or not there's a filter for golang, most of my development is in golang, so i either need to call your cli as a forked process or best to have a native library. i have never worked with haskell so not sure if i can import a haskell library from golang directly. i imagine there'd need to be a golang wrapper around the cli.
 You could use Libreoffice's command line interface to convert from .doc to a more manageable format. lowriter --convert-to odt some-document.doc  odt is not the only supported target, but doc --libreoffice--> odt --pandoc--> plain seems to give better results than e.g. doc --libreoffice--> txt or doc --libreoffice--> docx --pandoc--> plain.
 if that's the case, i'll stick with catdoc. my use case is to create a full text search index of the content, trading libre office cli for catdoc, i'd rather just stick with catdoc, but thanks.
 1. yes, only docx is supported. 2. for Go pandoc filters, this seems to work: https://github.com/oltolm/go-pandocfilters
 thanks, will check this out
 I write any document that doesn't need extensive custom typesetting (which is 90% of stuff) in org-mode and then use pandoc to convert it to "normal people" formats at the end. I have made a basic template for MS Word that looks pretty good.
 I wish they’d fix the md to adoc table conversion issues. Apart from that I love it.
 The core problem with Pandoc is that the internal document representation is limited to its particular flavor of Markdown. Any feature PD-MD doesn't support is ignored or loses semantics. You can see this in the poor ReST support (try converting captioned figures). It would be useful to rearchitect it with a Docbook-style semantics internally since they are more comprehensive than Markdown.
 As a guy attempting to transition from macOS to Linux:Pages to anything else, please.
 A quick Google suggests that the most straightforward way is to run an Automator script to convert everything to PDF using Pages itself.
 Yeah. But then you can't edit it. Converting it to opendoc or something would be more useful.
 Maybe this ( http://tyorex.com/iWorkConverter/ ) and then a batch doc->odt converter? (Though for the sake of sanity, I recommend avoid word processors where possible.)
 Pages will export to Word format, then use pandoc to generate markdown files. (Just one idea)
 But then I have to keep a Mac around, just to convert documents. Not ideal.
 You can do this via iCloud too (through the browser).
 Yeah, I know about that. I'm a government employee. Cloud services are mostly off limits to me.
 Pandoc is great! I use pandoc for all kinds of formal writing (conversion to PDF via LaTeX). We also run pandoc in production to produce customer-facing PDFs.
 Is there an equivalent of this for spreadsheets?
 The closest thing I'm aware of is the spreadsheet functionality in Emacs org-mode:https://orgmode.org/worg/org-tutorials/org-spreadsheet-intro...
 Sorry, I'm a little confused... How would I use org mode to convert between different spreadsheet formats?
 frustratingly slow for word docs. antiword is better for those of you who wish to convert word docs en masse
 I have used pandoc with uikit to autoconvert my markdown pages to html. Works like a charm.
 Really one of the best tool! Simple to use and makes things done.
 Where is .djvu?
 Do you need an option for that? You can convert to PDF and then pdf2djvu it.
 I believe the best you could do is extract the raw OCR'd text from the document (with some other tool). No formatting or text hierarchy is preserved in the OCR process, only the physical locations and size of the text on the page. From text, you can convert to Markdown or whatever and then manually edit to give the OCR text some structure.
 updated and secure.
 I know it's well intended and somewhat successful, but I can't help but thinking of xkcd.com/927Sorry, I couldn't resist.
 Although it does offer some useful extensions for Markdown, Pandoc doesn't attempt to establish new standards.It's a conversion tool for existing formats.
