Dap UI not working

[ray-x]

This check doesn't work for me, it keeps opening windows indefinitely

go.nvim/lua/go/dap.lua

Lines 272 to 275 in d402d9c

	local lys = require("dapui.windows").layouts
	if next(lys) and lys[1]:is_open() == false then
	require("dapui").open()
	end

@Davincible
What is your workflow? I checked debug with unit test it looks good.
Also just to be sure you are using latest dap-ui, right?

[Davincible]

Well I haven't actually gotten debugging to work yet, everytime I set a breakpoint and run GoDebug (without any arguments, just like that), I get could not remove /tmp/test/go/__debug_bin: remove /tmp/test/go/__debug_bin: no such file or directory

And the dap plugins has this notification; Error on launch: Failed to launch

[Davincible]

Everything should be latest, according to packer

[Davincible]

Just replicated everything with a very minimal config, same behavior for both.

local execute = vim.api.nvim_command
local fn = vim.fn
 
local install_path = fn.stdpath("data") .. "/site/pack/packer/start/packer.nvim"
 
if fn.empty(fn.glob(install_path)) > 0 then
        fn.system({ "git", "clone", "https://github.com/wbthomason/packer.nvim", install_path })
        execute("packadd packer.nvim")
end
 
return require("packer").startup(function()
        -- Packer can manage itself    
        use("wbthomason/packer.nvim")
 
        -- Nvim Treesitter
        use({ "nvim-treesitter/nvim-treesitter", run = ":TSUpdate" })
        use("kyazdani42/nvim-web-devicons")
 
        -- Golang
        use({
                "ray-x/go.nvim",
                requires = {
                        "mfussenegger/nvim-dap", -- Debug Adapter Protocol
                        "rcarriga/nvim-dap-ui",
                        "theHamsta/nvim-dap-virtual-text",
                        "ray-x/guihua.lua",
                },
        })
 
        local path = require("nvim-lsp-installer.core.path")
        local install_root_dir = path.concat({ vim.fn.stdpath("data"), "lsp_servers" })
        require("go").setup({
                gopls_cmd = { install_root_dir .. "/go/gopls" },
        })
 
        -- Nvim LSP
        use({ "neovim/nvim-lspconfig", "williamboman/nvim-lsp-installer", after = "go.nvim" })
end)

Your config look good. I pushed an update. Could you check if it works for you?

[Davincible]

You updated the readme? I tried GoDebug and GoDebug -c, -r, -p, all same result.

[ray-x]

Sorry, the merge was not successful, re-push a new version.
You can use init.lua in playground folder to run some tests.

[Davincible]

Yeeaahh it works now. But also the reason the UI keeps double opening is because the session failed to launch, and thus the check is session running fails, causing the UI to open again.

I can start a debug session now successfully. But if you just set your cursor on line 1 (package definition), it will fail to start the debug session as expected, but open the UI. If you then run GoDebug again, it doesn't detect a running session and re-opens another UI

Filed an issue here:
rcarriga/nvim-dap-ui#115
Also, commit a check for that as well.

Close this for now. Most parts of the issue are solved.
