Delve – debugger for the Go programming language

Delve is a source level debugger for the Go programming language.

The goal of the project is to provide a simple, full featured debugging tool for Go. Delve makes every attempt to be user-friendly, ensuring the user has to do the least amount of work possible to begin debugging their program.

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.

Available Commands:
attach Attach to running process and begin debugging.
connect Connect to a headless debug server.
core Examine a core dump.
dap [EXPERIMENTAL] Starts a TCP server communicating via Debug Adaptor Protocol.
debug Compile and begin debugging main package in current directory, or the package specified.
exec Execute a precompiled binary, and begin a debug session.
help Help about any command
run Deprecated command. Use 'debug' instead.
test Compile test binary and begin debugging program.
trace Compile and begin tracing program.
version Prints version.

Delve is free and open source software.

Features include:

  • Understands the Go runtime, data structures and expressions better than a general purpose debugger.
  • Aware of goroutines and other Go features.
  • Attach to a running process by simply specifying the process ID. Once attached to the process, you can do things such as switch goroutines, jump to a certain stack frame, and inspect state.
