lldb

This crate provides a safe binding to the public API for LLDB the debugger provided by the LLVM project. LLDB provides a modern, high performance debugger framework and is the default debugger for macOS and iOS.

This builds upon a lower level crate lldb-sys.

Dual licensed under the MIT and Apache 2 licenses.

Documentation

The API is fully documented with examples: https://endoli.github.io/lldb.rs/

Installation

This crate works with Cargo and is on crates.io. Add it to your Cargo.toml like so:

[dependencies]
lldb = "0.0.11"

Linux

Install the lldb and liblldb-dev packages for your platform so that you have both LLDB itself installed as well as the headers and other support files required. For example, on Ubuntu you can run sudo apt install lldb liblldb-dev.

macOS

You will need to have 2 environment variables set to do the build:

LLVM_ROOT - This points to the root of the LLVM source tree.
LLVM_BUILD_ROOT - This points to the root of an LLVM build directory. This may be the same as the LLVM source tree, especially if you're working from a binary install.

For now, you will have to set an @rpath manually on your executables so that they can find the LLDB.framework at runtime. This can be done with install_name_tool:

install_name_tool -add_rpath /Applications/Xcode.app/Contents/SharedFrameworks target/debug/examples/barebones

Alternatively, for testing and local work, you can set the DYLD_FRAMEWORK_PATH:

export DYLD_FRAMEWORK_PATH=/Applications/Xcode.app/Contents/SharedFrameworks

Development Guidelines

The official LLDB bindings for C++ and Python maintain very strict backwards compatibility. This has resulted in them having methods that are considered to be deprecated in favor of newer methods with more comprehensive arguments. The Rust bindings don't have that problem (yet), so we should try to only write bindings for the recommended usages and not the deprecated methods.

The documentation for the official bindings is also somewhat spotty. While it would be great to contribute upstream to improve that, we should seek to have these bindings be well documented and with more examples.

People should be jealous of the quality of our bindings. Sic itur ad astra.

Status of Implementation

Things are under active development. This project is not quite usable yet as some of the basic functionality is being written.

Support and Maintenance

I am developing this library largely on my own so far. I am able to offer support and maintenance, but would very much appreciate donations via Patreon. I can also provide commercial support, so feel free to contact me.
