About the typos source code spell checker

typos is a source code spell checker written Rust that’s useful for finding typos in code comments and variable names.

On MacOS you can install from Homebrew:

brew install typos-cli

and run with:

typos

It does tend to yield some false positives but it’s still useful.

Fixing typos in a project

I use it to populate Vim’s quickfix list via:

:cexpr system('typos --format=brief')

then use ,z to replace the word under cursor with the top spelling suggestion, which is usually right:

" ~/.vimrc

" Replace word under cursor with top spelling suggestion
nnoremap <leader>z 1z=

Haven’t tried it as a pre-commit hook or CI step yet but will investigate.
