# DBG
|
|
|
|
### What is DBG?
|
|
|
|
DBG is a Go debugger, written primarily in Go. It really needs a new name.
|
|
|
|
### Building
|
|
|
|
Currently, DBG requires the following [patch](https://codereview.appspot.com/117280043/) to be applied to your Go source to build.
|
|
|
|
### Features
|
|
|
|
* Attach to (trace) a running process
|
|
* Ability to launch a process and begin debugging it
|
|
* Set breakpoints
|
|
* Single step through a process
|
|
* Next through a process (step over / out of subroutines)
|
|
* Never retype commands, empty line defaults to previous command
|
|
|
|
### Usage
|
|
|
|
The debugger can be launched in two ways:
|
|
|
|
* Provide the name of the program you want to debug, and the debugger will launch it for you.
|
|
|
|
$ dbg -proc path/to/program
|
|
|
|
* Provide the pid of a currently running process, and the debugger will attach and begin the session.
|
|
|
|
$ dbg -pid 44839
|
|
|
|
Once inside a debugging session, the following commands may be used:
|
|
|
|
* `break` - Set break point at the entry point of a function, or at a specific file/line. Example: `break foo.go:13`.
|
|
|
|
* `step` - Single step through program.
|
|
|
|
* `next` - Step over to next source line.
|
|
|
|
### Upcoming features
|
|
|
|
* Handle Gos multithreaded nature better (follow goroutine accross thread contexts)
|
|
* In-scope variable evaluation
|
|
* In-scope variable setting
|
|
* Readline integration
|
|
* Ability to launch debugging session from debugged program, with breakpoint set correctly
|
|
* Support for OS X
