LLDBINIT

A gdbinit clone for LLDB aka how to make LLDB a bit more useful and less crappy

No original license by Deroko so I guess this is do whatever you want with this as long you keep original credits and sources references.

Original lldbinit code by Deroko @ https://github.com/deroko/lldbinit
gdbinit available @ https://github.com/gdbinit/Gdbinit

Huge thanks to Deroko for his original effort! Without it this would not exist.

Most of gdbinit functions are converted, and a bunch of new functions added.
Some of the commands that were passed to lldb command line were converted to internal API.

Ported to Python 3.x
Added xinfo, tele , mbp, vmmap, xnu_ commands supporting to debug XNU kernel, objective C.
Added iokit_print to display readable OSObject
Bug fixed for lldb with Python3 on newest macOS.
Support aarch64.
Improve better color to determinte region of an address

Requirements

Tested with lldb out of Xcode 9.2, should work with older versions (but not that old).
Optional Keystone Engine (https://www.keystone-engine.org) for assembler support.

How to install

cp lldbinit.py ~
echo "command script import  ~/lldbinit.py" >>~/.lldbinit

cp lldbinit.py /Library/Python/2.7/site-packages
echo "command script import lldbinit" >>~/.lldbinit

just copy it somewhere and use command script import path_to_script when you want to load it.

How to use

List all implemented commands with 'lldbinitcmds'

Configuration

There are some user configurable options on the header. You can also use the enable/disable commands to real time configure some options.

Features

The flow window shows the destination of calls, jmps, and returns, and also the class and selectors for Objective-C calls.

The crack family of commands allow you to automate return from functions with a value and skip code (for all your cracking isRegistered: and malware reversing needs) or breakpoint an address and set a given register to a value (also for all your cracking needs).

You can set the value of any register using its name, which is basically a shortcut for register write LLDB command.

The data window allows you to display the data of a certain memory location that you set with datawin command. Useful if you want to observe the contents of a string decryption routine for example.

The skip command allows you to skip exactly one instruction to next instruction (ignoring control flow!).
