twoslash-queries.nvim

Written in lua for nvim

Inspired by vscode-twoslash-queries, this plugin allows you to print typescript types as inline virtual text and dynamically update it instantly without having to move the cursor over the inspected variable

This is particularly useful when you are playing with complex typescript types:

"Added @typescript twoslash support to vscode with this little extension and I couldn't be happier with it"

How to install it

Packer

use("marilari88/twoslash-queries.nvim")

Make sure you have typescript language server properly installed and configured (personally I use Mason and Lspconfig plugins)

Then attach it on your tsserver in lspconfig setup

require("lspconfig")["tsserver"].setup({
    on_attach = function(client, bufnr)
       require("twoslash-queries").attach(client, bufnr)
    end,
})

Optionally you can define a custom keymap for TwoslashQueriesInspect command

vim.api.nvim_set_keymap('n',"<C-k>","<cmd>TwoslashQueriesInspect<CR>",{})

Config

You can override default config use setup function:

use({
   "marilari88/twoslash-queries.nvim",			
    config = function()
        require("twoslash-queries").setup({
            multi_line = true, -- to print types in multi line mode
            is_enabled = false, -- to keep disabled at startup and enable it on request with the TwoslashQueriesEnable 
            highlight = "Type", -- to set up a highlight group for the virtual text
	   })
    end,
})

Default config:

multi_line = false
is_enabled = true

Usage

Write a // ^? placing the sign ^ under the variable to inspected:

const variableToInspect = ....
//      ^?

Custom commands

:TwoslashQueriesEnable Enable the plugin for the current session
