slimux.nvim

Send cursor_line from the current Neovim buffer to a configurable tmux pane.

Example setup (and installation)

Via lazy:

require("lazy").setup({
  {
    'mokanfar/slimux.nvim',
    config = function()
      local slimux = require('slimux')
      slimux.setup({
        target_socket = slimux.get_tmux_socket(),

        -- This is targetting tmux window 2 and will send command there
        target_pane = string.format('%s.2', slimux.get_tmux_window()),
      })
      vim.keymap.set('n', '<leader>r', ':lua require("slimux").capture_current_line_text()<CR>',
        { desc = 'Send cursor_line as cmd to a tmux window' })
    end
  }
})

The target pane that text is sent to follows the standard send-keys format, so e.g. the second pane in the first window would be denoted as 0.1. This target pane can be configured initially in the setup function shown above, but also on the fly via the provided configure_target_socket function, like in the below snippet:

:lua require('slimux').configure_target_pane('0.1')

Additionally, some effort is taken to automatically escape input to send it to its destination intact. The array of escaped strings can be overridden in the above setup function, with the default setting being the below:

escaped_strings = { '\\', ';', '"', '$', '\'' }

Also, a reminder that pane numbers can be shown via prefix + q, which in a standard install will be C-b + q.
