# Logging

Debugging an application with the freedom of a rich API can lead to flows which are hard to unravel. To aid the user in the debugging process, libdebug provides logging, which can be enabled through argv parameters.

The available logging levels are: - debugger - pipe - dbg

As reported in this documentation, the argv parameters are lowercase. This choice is made to avoid conflicts with (Gallopsled/pwntools), which intercepts uppercase arguments.

## Debugger Logging

The debugger option displays all logs related to the debugging operations performed on the process by libdebug.

## Pipe Logging

The pipe option, on the other hand, displays all logs related to interactions with the process pipe: bytes received and bytes sent.

## The best of both worlds

The dbg option is the combination of the pipe and debugger options. It displays all logs related to the debugging operations performed on the process by libdebug, as well as interactions with the process pipe: bytes received and bytes sent.

## Temporary Logging

Logger levels can be temporarily enabled at runtime using a with statement, as shown in the following example.

    from libdebug import libcontext
    with libcontext.tmp(pipe_logger='INFO', debugger_logger='DEBUG'):
        r.sendline(b'gimme the flag')
