Built a tiny Neovim plugin because I got tired of constantly copy/pasting between nvim and tmux.

It’s called send-to-tmux.nvim.

The idea is simple:

Select text in Neovim → send it directly to a tmux pane.

Sounds small, but it ended up improving my workflow way more than I expected, especially for AI coding / REPL-heavy workflows.

Some things it can do:

• send current line or visual selection
• reliably send multiline content via tmux paste-buffer
• edit content in a floating window before sending
• generate file:line / file:start-end references for AI agents
• preview pane info + recent output before choosing target pane
• optional auto-enter + auto-focus behavior

I originally made it because my workflow looked like this all day:

• write code in Neovim
• run commands in adjacent tmux pane
• copy
• switch pane
• paste
• switch back
• repeat 500 times

After a while, the friction becomes surprisingly annoying.

Now it feels much more like Neovim and tmux are one environment instead of two separate tools.

Feels especially nice when working with:

• Claude Code
• Codex CLI
• Python/IPython
• Node REPL
• shell-heavy workflows
• vibe coding setups

Curious if anyone else here has built similar “micro workflow” plugins lately.
