[Question] Anything like <Plug>VimspectorBalloonEval

[ioperations]

vimspector allow mouse hover to popup variable value , is there any thing like this or can it be implemented ?

[rcarriga]

As vimspector states, it uses the balloons feature of Vim which Neovim doesn't have so no mouse hover cannot be implemented.

actually there do have a snippet , but i cannot locate mouse position and pass the right expression to dapui,

local hover_time = 500
local hover_timer = nil
vim.o.mousemoveevent = true

local mousemove_str = vim.api.nvim_replace_termcodes("<MouseMove>", false, false, true)
local dap = require "dap"
local dapui = require "dapui"
   
 vim.on_key(function(str)
     if str == mousemove_str then
         if hover_timer then
             hover_timer:close()
         end
         hover_timer = vim.defer_fn(function()
             hover_timer = nil
             if dap.session() ~= nil then
             --  print("looping " .. vim.loop.now())
             --  pop()
                  dapui.eval()
             end
         end, hover_time)
     end
 end)

and there do have other issue, (when moving the mouse to float window that dapui managed, no new float window should be produced)

popup function that may reminds you

local function pop()
    local expr
    local args
    local async = require "dapui.async"
    local dapui = require "dapui"
    local util = require "dapui.util"

    async.run(function()
        if not dap.session() then
            return
        end
        args = args or {}
        if not expr then
            expr = util.get_current_expr()
        end
        if open_float then
            if prev_expr == expr then
                open_float:jump_to()
                return
            else
                open_float:close()
            end
        end
        prev_expr = expr
        local elem = dapui.elements.hover
        elem.set_expression(expr, args.context)
        local v = vim.fn.getmousepos()
        local line_no = v.line
        local col_no = v.column

        local position = { line = line_no, col = col_no }
        open_float = require("dapui.windows").open_float("hover", elem, position, args)
        if open_float then
            open_float:listen("close", function()
                open_float = nil
            end)
        end
    end)
end
