NAME

dlv-dap - Starts a headless TCP server communicating via Debug Adaptor Protocol (DAP).

SYNOPSIS

dlv dap [flags]

DESCRIPTION

Starts a headless TCP server communicating via Debug Adaptor Protocol (DAP).

The server is always headless and requires a DAP client like VS Code to connect and request a binary to be launched or a process to be attached to. The following modes can be specified via the client’s launch config: - launch + exec (executes precompiled binary, like ’dlv exec’) - launch + debug (builds and launches, like ’dlv debug’) - launch + test (builds and tests, like ’dlv test’) - launch + replay (replays an rr trace, like ’dlv replay’) - launch + core (replays a core dump file, like ’dlv core’) - attach + local (attaches to a running process, like ’dlv attach’)

Program and output binary paths will be interpreted relative to dlv’s working directory.

This server does not accept multiple client connections (--accept-multiclient). Use ’dlv [command] --headless’ instead and a DAP client with attach + remote config. While --continue is not supported, stopOnEntry launch/attach attribute can be used to control if execution is resumed at the start of the debug session.

The --client-addr flag is a special flag that makes the server initiate a debug session by dialing in to the host:port where a DAP client is waiting. This server process will exit when the debug session ends.

OPTIONS

	--client-addr=""	host:port where the DAP client is waiting for the DAP server to dial in
	-h, --help[=false]	help for dap

OPTIONS INHERITED FROM PARENT COMMANDS

	--accept-multiclient[=false]	Allows a headless server to accept multiple client connections via JSON-RPC or DAP.
	--allow-non-terminal-interactive[=false]	Allows interactive sessions of Delve that don’t have a terminal as stdin, stdout and stderr
	--api-version=1	Selects JSON-RPC API version when headless. New clients should use v2. Can be reset via RPCServer.SetApiVersion. See Documentation/api/json-rpc/README.md.
	--backend="default"	Backend selection (see ’dlv help backend’).
	--build-flags=""	Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v"
	--check-go-version[=true]	Exits if the version of Go in use is not compatible (too old or too new) with the version of Delve.
	--disable-aslr[=false]	Disables address space randomization
	--headless[=false]	Run debug server only, in headless mode. Server will accept both JSON-RPC or DAP client connections.
	--init=""	Init file, executed by the terminal client.
	-l, --listen="127.0.0.1:0"	Debugging server listen address.
	--log[=false]	Enable debugging server logging.
	--log-dest=""	Writes logs to the specified file or file descriptor (see ’dlv help log’).
	--log-output=""	Comma separated list of components that should produce debug output (see ’dlv help log’)
	--only-same-user[=true]	Only connections from the same user that started this instance of Delve are allowed to connect.
	-r, --redirect=[]	Specifies redirect rules for target process (see ’dlv help redirect’)
	--wd=""	Working directory for running the program.
