## dlv dap Starts a headless TCP server communicating via Debug Adaptor Protocol (DAP). ### Synopsis 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. ``` dlv dap [flags] ``` ### Options ``` --client-addr string host:port where the DAP client is waiting for the DAP server to dial in -h, --help help for dap ``` ### Options inherited from parent commands ``` --accept-multiclient Allows a headless server to accept multiple client connections via JSON-RPC or DAP. --allow-non-terminal-interactive Allows interactive sessions of Delve that don't have a terminal as stdin, stdout and stderr --api-version int 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. (default 1) --backend string Backend selection (see 'dlv help backend'). (default "default") --build-flags string Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v" --check-go-version Exits if the version of Go in use is not compatible (too old or too new) with the version of Delve. (default true) --disable-aslr Disables address space randomization --headless Run debug server only, in headless mode. Server will accept both JSON-RPC or DAP client connections. --init string Init file, executed by the terminal client. -l, --listen string Debugging server listen address. (default "127.0.0.1:0") --log Enable debugging server logging. --log-dest string Writes logs to the specified file or file descriptor (see 'dlv help log'). --log-output string Comma separated list of components that should produce debug output (see 'dlv help log') --only-same-user Only connections from the same user that started this instance of Delve are allowed to connect. (default true) -r, --redirect stringArray Specifies redirect rules for target process (see 'dlv help redirect') --wd string Working directory for running the program. ``` ### SEE ALSO * [dlv](dlv.md) - Delve is a debugger for the Go programming language.
