Delve is a debugger for the Go programming language.

Synopsis

Delve is a source level debugger for Go programs.

Delve enables you to interact with your program by controlling the execution of the process, evaluating variables, and providing information of thread / goroutine state, CPU register state and more.

The goal of this tool is to provide a simple yet powerful interface for debugging Go programs.

Pass flags to the program you are debugging using --, for example:

dlv exec ./hello -- server --config conf/config.toml

Options

      --accept-multiclient   Allows a headless server to accept multiple client connections.
      --api-version int      Selects 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.
      --check-go-version     Checks that the version of Go in use is compatible with Delve. (default true)
      --headless             Run debug server only, in headless mode.
      --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)
      --wd string            Working directory for running the program. (default ".")
