[Feature Request] Improve double-click detection

[beelzebielsk]

Vim/Neovim's double-click detection is frustrating. Sometimes it will miss a double-click because my finger moved slightly. I use vim often on a touchscreen device, so it's a problem for me.

Could you improve double-click detection? Do you consider that within scope of your plugin? I was thinking you could consider it a gesture. If not, let me know and I'll either make my own plugin or open an issue with neovim.

I believe the problem is both clicks have to happen in the same cell on screen. Some concrete ideas I have for improving detection:

• Track clicks, when they happen and their locations. This may be possible by mapping LeftMouse to some click logger in gesture.nvim.
• If a series of clicks, starting from the latest click, meet some criteria for being close enough and fast enough, send out a double-click. Some example criteria are clicks happen within a 3x3 box, and within some short window of time. The click could be dispatched to the midpoint of the clicks.

This can be extended for triple and quadruple clicks, too.

Thanks interesting request!

But, I think the feature should be implement by other plugin. Even if implemented in a way that fits the current interface, the accuracy may not be satisfactory.

📝 didn't work experimental code.

local gesture = require("gesture")

vim.keymap.set("n", "<LeftMouse>", function()
  gesture.draw({ length_thresholds = { x = 0, y = 0 } })
  gesture.suspend()
end, { silent = true })

gesture.register({
  name = "test",
  inputs = { gesture.up({ max_length = 3 }), gesture.up({ max_length = 3 }) },
  action = function()
    print("test")
  end,
  nowait = true,
})

Thanks! I appreciate the feedback.
