vim-dirtytalk: spellcheck dictionary for programmers 📖

This (neo)vim plugin is a dynamically updateable spellcheck dictionary, to be used in conjunction with Vim's native spell checking feature. It is meant to aid with writing technical documentation (such as project's READMEs, runbooks, code comments, etc.), by providing you with a list of commonly used programming-related words, to supplement Vim's built-in English word list. Does your screen turn all red as soon as you :set spell on your project's README? You might want to give vim-dirtytalk a try!

Included word lists

Currently the plugin comes bundled with following word lists, compiled into one big list at installation time:

List name	Example words
acronyms	API, JSON, PaaS
algorithms	quicksort, subtree, memoization
brands	GitHub, AdSense, DynamoDB
comments	TODO, FIXME, XXX
cpp	const, enum, lvalue
docker	Dockerfile, cgroups, ENTRYPOINT
file-extensions	.js, .yaml, .lua
git	submodule, worktree, rebase
html	h1, iframe, fieldset
kubernetes	ConfigMap, CSIDriver, HorizontalPodAutoscaler
lorem-ipsum	Lorem, ipsum, dolor
nerd-fonts	 ,  , 
prometheus	PromQL, Alertmanager, Pushgateway
python	docstring, iterable, awaitable
unix	SIGTERM, chroot, grep
versions	v1, v2, v3

You can disable lists you don't want to use. See the customization section for details.

Installation

Install the plugin using your favorite plugin manager. Ensure that the :DirtytalkUpdate command is executed after install and update. Example for vim-plug:

Plug 'psliwka/vim-dirtytalk', { 'do': ':DirtytalkUpdate' }

Then include your freshly-compiled programming dictionary in your spelllang setting. Example:

set spelllang=en,programming

Alternatively you can do both steps via your plugin manager. Example for lazy.nvim:

{
    "psliwka/vim-dirtytalk",
    build = ":DirtytalkUpdate",
    config = function()
        vim.opt.spelllang = { "en", "programming" }
    end,
}

Usage

Once installed, the plugin integrates seamlessly with Vim's native spell checking (see :h spell for details on how to use it). Make sure you've enabled spell checking with :set spell!

Customization

To disable a word list, add it to g:dirtytalk_blacklist variable. Example:

let g:dirtytalk_blacklist=['lorem-ipsum']

Remember to re-run :DirtytalkUpdate after changing the blacklist.

Known issues

• Nerd fonts symbols are marked as rare words, to exclude them from spell suggestions (z= and friends). This is needed, because otherwise their large amount grinds Vim's spell suggestions algorithm to a halt. As a side effect, all nerd fonts symbols are highlighted with SpellRare group (but at least not with SpellBad, as they would if they hadn't been included in the wordlist at all). If it bothers you, you can disable highlighting rare words entirely with :highlight clear SpellRare as a workaround.

You are encouraged to submit new word lists and other improvements to this project. See CONTRIBUTING for details.
