dap-utils.nvim

Utilities to provide a better experience for using nvim-dap.

More neovim plugins

Dependencies

• niuiic/core.nvim
• mfussenegger/nvim-dap
• rcarriga/nvim-dap-ui
• nvim-telescope/telescope.nvim

Usage

continue

• Safely inject custom operations before start to debug.
• Replace the original continue with require("dap-utils").continue(), and start to debug with this function.

Async functions or some ui operations may cause error if they are called in program function.

store_breakpoints

• Store all breakpoints to a file.
• require("dap-utils").store_breakpoints(file_path, root_pattern)
• root_pattern is .git by default.

Use it with a session manager, see niuiic/multiple-session.nvim.

restore_breakpoints

• Restore all breakpoints from a file.
• require("dap-utils").restore_breakpoints(file_path, root_pattern)
• root_pattern is .git by default.

search_breakpoints

• Search breakpoints with telescope.nvim.
• require("dap-utils").search_breakpoints(opts)
• opts is optional, it's same to telescope picker opts.

toggle_breakpoints

• Enable/Disable all breakpoints.
• require("dap-utils").toggle_breakpoints(root_pattern).
• Breakpoints disabled can be stored by store_breakpoints.
• require("dap").clear_breakpoints() cannot remove disabled breakpoints, use require("dap-utils").clear_breakpoints() instead.

store_watches

• Store all watches to a file.
• require("dap-utils").store_watches(file_path)

restore_watches

• Restore all watches from a file.
• require("dap-utils").restore_watches(file_path)

remove_watches

• Remove all watches.
• require("dap-utils").remove_watches()

Config

Here is an example to debug rust in a workspace.

require("dap-utils").setup({
	-- filetype = function while returns dap config
	rust = function(run)
		-- nvim-dap start to work after call `run`
		-- the arguments of `run` is same to `dap.run`, see :h dap-api.
		local config = {
			-- `name` is required for config
			name = "Launch",
			type = "lldb",
			request = "launch",
			program = nil,
			cwd = "${workspaceFolder}",
			stopOnEntry = false,
			args = {},
		}
		local core = require("core")
		vim.cmd("!cargo build")
		local root_path = core.file.root_path()
		local target_dir = root_path .. "/target/debug/"
		if core.file.file_or_dir_exists(target_dir) then
			local executable = {}
			for path, path_type in vim.fs.dir(target_dir) do
				if path_type == "file" then
					local perm = vim.fn.getfperm(target_dir .. path)
					if string.match(perm, "x", 3) then
						table.insert(executable, path)
					end
				end
			end
			if #executable == 1 then
				config.program = target_dir .. executable[1]
				run(config)
			else
				vim.ui.select(executable, { prompt = "Select executable" }, function(choice)
					if not choice then
						return
					end
					config.program = target_dir .. choice
					run(config)
				end)
			end
		else
			vim.ui.input({ prompt = "Path to executable: ", default = root_path .. "/target/debug/" }, function(input)
				config.program = input
				run(config)
			end)
		end
	end,
})

You can also pass multiple configurations into run.

require("dap-utils").setup({
	javascript = function(run)
		local core = require("core")
		run({
			{
				name = "Launch project",
				type = "pwa-node",
				request = "launch",
				cwd = "${workspaceFolder}",
				runtimeExecutable = "pnpm",
				runtimeArgs = {
					"debug",
				},
			},
			{
				name = "Launch cmd",
				type = "pwa-node",
				request = "launch",
				cwd = core.file.root_path(),
				runtimeExecutable = "pnpm",
				runtimeArgs = {
					"debug:cmd",
				},
			},
			{
				name = "Launch file",
				type = "pwa-node",
				request = "launch",
				program = "${file}",
				cwd = "${workspaceFolder}",
			},
			{
				name = "Attach",
				type = "pwa-node",
				request = "attach",
				processId = require("dap.utils").pick_process,
				cwd = "${workspaceFolder}",
			},
		})
	end,
})
