Writing is arguably the most important activity for an academic. An academic’s job is to create and disseminate knowledge, and this cannot be done without effective writing. Thus, it is important to pick the right tools for the job. These tools are split into the categories of editor, typesetting language, and support tools. In this post, I explain my academic writing workflow with Neovim, Pandoc and LaTeX, and a curated set of plugins for writing tasks.

If you already use my combination of Neovim, Pandoc, and LaTeX, you’ll probably want to skip ahead to the last section.

## Writing with Neovim

In the programmer community, the “Emacs or Vim” debate is an unending flame war. I have no intent of entering this debate1. Use whichever editor works for you; Vim (specifically Neovim) works for me. However — particularly in computer science — there seems to be a bias toward Emacs, so I’ll explain my preference.

For formal academic writing (especially in fields outside of computer science), tools like Microsoft Word or a specialized LaTeX editor are popular. There are good reasons to use these programs, but using Vim2 is often the better choice. Work in computer science and other STEM fields involves writing in a blend of formats — coding in various languages, writing formal papers with formulae, graphics, and ordinary text, and (for some of us) making detailed research notes for planning. Given this diversity of formats, there’s a benefit to using the same editor for them all, if that editor can adequately support them. Fortunately, Vim, Emacs, and most other common programming editors have excellent support for all the formats an academic will regularly need to use.

Assuming you buy my argument for using a programming editor instead of Word, I still need to argue for my choice of Vim in particular. In my experience, though Vim has a much higher learning curve than Emacs, Sublime, etc., the investment of time in learning Vim’s modal editing language pays dividends. Other editors provide means of rapidly changing and navigating text; I find Vim’s language of modifiers and movement operators the most expressive and flexible. It’s worth noting that most text editors have decent plugins for emulating Vim3; if you already use another editor and want to try Vim’s editing paradigm, these can be a good option.

Finally, I favor Vim over Emacs for its plugin ecosystem, ease of use in the terminal4, and speed. Vim’s customization language (Vim script) is admittedly horrible compared to Emacs Lisp, but Neovim fixes some of this deficiency through its remote plugin API. Given that Neovim also adds an asynchronous job API5, cleans up the Vim source code, and offers greater future maintainability with no regressions from Vim’s functionality, it is the best choice of Vim-family editors.

## Pandoc Markdown and LaTeX

Regardless of the editor you choose, it is important to give thought to the right language6 to use for writing. There are many options — popular ones include plain text, Markdown of various flavors, Wiki format, Emacs’ org-mode, and LaTeX — but I think Pandoc and LaTeX form the best pairing for academic writing. I’ll give some background on both and explain why I have this preference.

Pandoc is a wonderful tool for converting text written in one of many formats to an even larger set of output formats. It takes as input Markdown, Emacs Org-Mode syntax, Microsoft Word files, and several other formats7, and outputs PDFs, LaTeX, HTML, and others. In typical use, you write in Pandoc Markdown — ordinary Markdown8 extended with some useful features (including footnotes, tables, definition lists, embedded math, etc.) — and output whatever format you need. Pandoc is great for academic writing because it allows you to easily make professional-looking documents with figures, tables, automatically-processed citations, and math. Further, because Pandoc can convert Markdown to many output formats, it’s trivial to write your content once and publish it in several forms (e.g. in a PDF for submission to a journal or conference, in HTML for publication on a website, etc.). Plus, Markdown is so easy and natural to write that you can complete documents very quickly. In fact, I wrote this entire post in Markdown.

With all that said, Markdown does have some shortcomings: Though the “default” is usually very nice, it does not give you enough expressive power to customize every aspect of your document’s appearance and typesetting. For that, you need something like LaTeX. To quote the project’s “About” page9, “LaTeX…is a document preparation system for high-quality typesetting.” It is already heavily used in several areas of academia (CS, mathematics, and physics in particular), but is suitable for any form of academic writing. LaTeX’s “best known” strength is its phenomenal typesetting of math symbols, but it also provides rich facilities for controlling the layout and appearance of your document. Using LaTeX has an associated learning curve, but there are more good learning resources10 now than ever. Moreover, mastering LaTeX is well worth the work - the most beautiful academic documents I’ve seen use LaTeX for formatting.

So, why are Pandoc and LaTeX together a great setup for academic writing? Pandoc is very easy to write, and very easy to use to get an attractive result — including math, figures, and the like. However, it isn’t easy to tweak appearance in Pandoc Markdown — but it is in LaTeX. Fortunately, Pandoc can convert from Markdown straight to LaTeX. This functionality presents an attractive workflow: You can start a project writing in Markdown. Use it for your notes, your planning, and your early paper drafts. When you reach the stage of a project where the content is largely done and it is time to focus on tweaking the appearance and making everything “just so”, you can run Pandoc on your Markdown file to output LaTeX source and continue editing with greater control.

Thus, by starting your writing in Markdown and ending with LaTeX, you get a nice balance of ease of use for the 80% of the work that doesn’t require tremendous power, and all the typesetting power you could want for the remaining 20%.

## Support Tools

The final piece pulling together the elements of my academic writing setup is a curated set of writing plugins for Neovim. These fall loosely into three categories: language plugins, focus plugins, and editing plugins. I do use many plugins other than these; you can see the full set in my dotfiles repo.

### Language Plugins

Language plugins are plugins which add support to Neovim for new languages. While Neovim offers basic syntax highlighting support for many languages out of the box, there’s a lot more that these plugins have to offer.

I use the following plugins for Pandoc Markdown:

• vim-pandoc: Adds several integrations between Vim and Pandoc
• the ones I rely on are auto-completion of bibliography entries and correct handling of hard and soft line wraps.
• vim-pandoc-syntax: Provides syntax highlighting for Pandoc Markdown files. In particular, it also integrates with Vim’s conceal feature, which makes certain elements of Pandoc’s formatting syntax render in more visually appealing ways.
• vim-pandoc-after: Adds integrations with unite.vim11 and UltiSnips.

I also use12 a plugin I wrote, buildit.nvim to compile my Markdown into PDF form using a Makefile. While vim-pandoc can asynchronously run the Pandoc program, I find it easier to type the options I want to pass just once into a Makefile and know that my collaborators can also easily build the text without having to type the exact same invocation.

For LaTeX, I am a big fan of vimtex. vimtex offers auto-compilation on every save, completion of citation and file names, text objects for LaTeX environments, commands, etc., better LaTeX syntax highlighting, and new mappings for working with LaTeX.

### Focus Plugins

A focus plugin is a plugin designed to help you focus on what you’re writing. While working on a large document, it can be easy to become distracted by sections other than the one you’re currently writing, indicators of length or other metrics in the editor, and other extraneous information. The two focus plugins I use help to eliminate these distractions and let you pay attention to the writing at hand.

The first of these focus plugins is goyo.vim. goyo essentially hides all the unnecessary parts of the editor while you’re writing: Line numbers, status displays, etc. It focuses the text in the center of the screen. While this functionality sounds simple, it’s surprisingly nice for writing.

My second focus plugin is limelight.vim. limelight works very well with goyo, as it brightens the color of the current paragraph of text, and dims everything else. In other words, everything but what you need to be focused on fades to the background.

### Editing Plugins

The final set of plugins I use for writing falls into the category of editing plugins. An editing plugin is one designed to help make your writing better — things like grammar checks, word usage, and style issues.

For the first of these issues, I use vim-grammarous. vim-grammarous, as the name implies, checks your writing for grammar errors using LanguageTool. It can also use the suggested fixes from LanguageTool to automatically edit your writing. It’s as simple as that, but very useful.

vim-ditto helps to avoid using the same words ad nauseam in your writing13. If it detects that you’ve used the same word too many times too close to one another (ignoring, of course, very common words), it will highlight the overused term in red. This plugin is another great example of a simple piece of functionality that can drastically improve your writing.

Finally, for more advanced checks of usage and style, I like vim-wordy. While I’m a relatively new user of vim-wordy myself, and thus still learning all it can do, it is a very powerful plugin for writers. It can check for things like weak and lazy words, redundant or problematic usage, weasel words, the passive voice, and much, much more. I typically run vim-wordy once I’ve finished my first draft, to highlight areas in need of special editing attention.
