I have a Mojo repository with uv: [GitHub - gonsolo/mojo\_gpu\_raytracer](https://github.com/gonsolo/mojo_gpu_raytracer)

To edit: “uv run vim file.mojo”

In ~/.vimrc:

> if executable(‘uv’)  
> au User lsp\_setup call lsp#register\_server({  
> \ ‘name’: ‘Mojo Language Server’,  
> \ ‘cmd’: {server\_info → [‘uv’, ‘run’, ‘–’, ‘.venv/lib/python3.13/site-packages/max/bin/mojo-lsp-server’, ‘-I’, ‘.venv/lib/python3.13/site-packages/max/lib/mojo’]},  
> \ ‘whitelist’: [‘mojo’],  
> \ })  
> endif  
> autocmd FileType mojo nnoremap \<C-]\> :LspDefinition  
> autocmd FileType mojo setlocal omnifunc=lsp#complete
