Nostr + Post = Nost

Only write and save on Neovim (or Vim). You can post an event to Nostr!

Preparation

nvim config/nsec.txt # Input nsec1...
chmod 600 config/nsec.txt

nvim config/relays.txt # Input relay URLs
# Example
<<EOF
wss://nostr.example.com
wss://another-relay.example.com
# wss://invalid-relay.example.com
# The line starting with # is ignored.
wss://third-relay.example.com
EOF

docker container run -d --restart=always \
-v $PWD/config:/workspace/config:ro \
-v $PWD/data:/workspace/data \
-u $UID \
-e RUST_LOG=info \
kaosf/nost:latest

nvim data/content.txt

Edit and :w to publish an event of kind 1.

The container detects your WatchMask::MODIFY event of data/content.txt, and post it to Nostr.

My Vim script example

function! s:nost()
  if expand("%:p") != "/path/to/data/content.txt"
    return
  endif
  w
  sleep 1
  goto 1
  d 9999
  redraw
endfunction
nnoremap <silent> sn :call <SID>nost()<CR>

Lua version:

local function nost()
	if vim.fn.expand("%:p") ~= "/path/to/data/content.txt" then
		return
	end
	vim.cmd("w")
	vim.cmd("sleep 1")
	vim.cmd("goto 1")
	vim.cmd("d 9999")
	vim.cmd("redraw")
end
vim.keymap.set("n", "sn", nost, { silent = true })

Log viewer

# Version 1 style
docker run -d ... --name nost kaosf/nost:latest
# Run with --name option.

docker logs -f nost
