an example of narrow region implementation for nvim

feature/limits

• aimed to selection lines, not range
• no nested nag
• only one nag for one buffer
• hard to properly maintain the original buffer's &modifiable, so let user concern it
• no syntax/filetype nor treesitter/lsp support
• diff+patch

status

• just work

prerequisites

• linux
• nvim 0.12.*
• haolian9/infra.nvim

usage

• select text then :lua require'nag'.tab() or nag.split(side: 'right'|'left'|'above'|'below')
• an example for adding a usercmd, requiring haolian9/cmds.nvim

do --:Nag
  local function action(args)
    local open = args.open
    local nag = require("nag")
    if open == "tab" then return nag.tab() end
    nag.split(open)
  end
  local comp = cmds.ArgComp.constant({ "tab", "left", "right", "above", "below" })

  local spell = cmds.Spell("Nag", action)
  spell:enable("range")
  spell:add_arg("open", "string", false, "tab", comp)
  cmds.cast(spell)
end

thanks
