Does anyone know a vim plugin for StarkNet smart contracts?

Yes! I wrote a Vim plugin for Cairo, it's fully updated for Cairo v0.10.0 syntax too.

https://github.com/0xHyoga/starknet-vim

To get the full power of Starknet-Vim I recommend using vim-ale and universal c-tags. If you check out the starknet-vim repository there's a section on how to install these.

1-- Asynchronous linting

2-- Syntax highlighting

3-- Auto-format with <C-y>

4--c-tags to show the file functions according to decorators (storage_vars, events, view, external, etc.)

Here is a small demo of starknet-vim

To change keybinding for auto-format just edit ftplugin/cairo.vim

function! CairoFormat()
  silent !clear
  silent execute "!cairo-format -i " . bufname('%') | execute ':redraw!'
endfunction

command! CairoFormat :call CairoFormat()

nnoremap** <C-y> **:call CairoFormat() <CR>

Note: This is a work in progress. I am updating it as i go deeper into the Cairo rabbit hole ;)

Any questions feel free to ask!

Hey, I found one more vim extension for starknet/cairo by 0xAurelou. This plugin supports vim Syntax for cairo v0.10 and hopefully Cairo 1.0 will be supported as well. https://github.com/0xAurelou/cairo_vim

The installation instruction

Just copy paste this in your

~/.vim/syntax/cairo.vim

Be sure you have this lines in your .vimrc

"Add Cairo Support
au BufReadPost *.cairo set filetype=cairo
au Filetype cairo set syntax=cairo
