❗ NXWM is currently in alpha status, expect crashes/hangs and constant API change

NXWM 0.0.1

Neovim X11 Window Manager allows you to use x11 windows as if they were buffers. When entering a x-window-buffer, you'll need to start insert-mode to focus the x-window (unless some configurations are set to do this automatically).

Requirements

libx11
glibc
Terminal supporting TIOCGWINSZ
- Recommended terminal is kitty
- Run :lua= require'nxwm'.term_supported() to check
  - NOTE: some terminals may support TIOCGWINSZ while still not working (like neovim-qt)

Installation

Use whichever package manager you like.
It is recommended to lock/pin the plugin to one version because of API changes.

Configuration

Using require("nxwm").setup({}) is not required, it is only there if you want to change the default config.

{
    --What happens when a new x-window is created
    on_win_open=function (buf,xwin)
        vim.cmd.vsplit()
        vim.api.nvim_set_current_buf(buf)
    end,
    --Configuration to pass to window
    --`conf` is global config
    on_win_get_conf=function (conf,xwin) return conf end,
    --How to handle when multiple windows in the same tabpage has the x-window-buffer open
    on_multiple_win_open=function (vwins,buf,xwin)
        for k,vwin in ipairs(vwins) do
            if k~=1 then
                local scratchbuf=vim.api.nvim_create_buf(false,true)
                vim.bo[scratchbuf].bufhidden='wipe'
                vim.api.nvim_win_set_buf(vwin,scratchbuf)
            end
        end
    end,
    --Whether to be more verbose
    verbal=false,
    --Map to unfocus a window
    unfocus_map='<A-F4>',
    --Create your own mappings
    --IMPORTANT: the x-window needs to be focused for such mappings to work
    maps={
        --{'<C-A-del>',function () vim.cmd'quitall!' end},
        --Or you could also have lhs as a table
        --{{mods={'control','mod1'},key='Delete'},function () vim.cmd'quitall!' end},
    },
    --Window-opt: auto focus x-window when entering x-window-buffer
    autofocus=false,
    --Window-opt: try-delete x-window if no vim-window shows buffer (similar to `bufhidden=wipe`)
    delhidden=true,
    --Window-opt: when click on x-window, goto that buffer (may not focus x-window)
    clickgoto=true,
}

Usage (simple)

Start

Install sx.
Run sx {NXWM} in a tty where {NXWM} is path to a terminal which runs Neovim and starts NXWM.
NOTE: the terminal should have it's start in the top left, have zero padding, have no title bar...
Examples of what {NXWM} could be:
- kitty: kitty -c NONE -o placement_strategy=top-left -e nvim -c 'lua require("nxwm").start()'
- alacritty: alacritty --config-file /dev/null -e nvim -c 'lua require("nxwm").start()'
- wezterm: wezterm -n --config enable_tab_bar=false --config window_padding='{left=0,right=0,top=0,bottom=0}' start nvim -c 'lua require"nxwm".start()'

Use

Open up a terminal (with :term) and run your wanted GUI. NOTE: x-windows aren't auto focused by default, so start insert (by pressing i or similar) and then you'll focus the window. To unfocus an x-window, either click into another buffer, or press alt-F4(unless the default config has been changed).
