auxtools

auxtools is a Rust-based successor to the extools project.

Currently, it implements some of the features such as the debug server, but is planned to supplant most functionality (maptick, etc.).

Code Documentation: https://auxtools.willox.dev

Features

Code Coverage - A tool to generate cobertura code coverage XML reports for a codebase. Note that, due to a BYOND issue it requires some additional work to have properly un-mangled file names in the report.

Debug Server - Working with SpaceManiac's SpacemanDMM, Auxtools interfaces with the debugger frontend to provide debugger information and management of breakpoints.

Dissassembly - When currently stopped at a breakpoint, enter the #dis command into the Debug Console in VSC to see the DM bytecode for the current proc. You can also provide it any arbitrary proc path like #dis /mob/proc/Life.

Dependencies

These instructions were taken directly from tgstation's rust-g documentation.

The Rust compiler:

  1. Install the Rust compiler's dependencies (primarily the system linker):

  2. Use the Rust installer, or another Rust installation method, or run the following:

    curl https://sh.rustup.rs -sSfo rustup-init.sh
    chmod +x rustup-init.sh
    ./rustup-init.sh
    
  3. Add the 32-bit compilation target:

    # Clone the `auxtools` repository to a directory of your choice
    git clone https://github.com/willox/auxtools
    # in the `auxtools` directory...
    cd auxtools
    # Linux
    rustup target add i686-unknown-linux-gnu
    # Windows
    rustup target add i686-pc-windows-msvc
    

System libraries:

  • Ubuntu and Debian users run:

    sudo dpkg --add-architecture i386
    sudo apt-get update
    sudo apt-get install build-essential g++-multilib libc6-i386 libstdc++6:i386
    
  • Other Linux distributions install the appropriate 32-bit development and 32-bit runtime packages.

Compiling

The Cargo tool handles compilation, as well as automatically downloading and compiling all Rust dependencies. To compile in release mode (recommended for speed):

Linux:

export PKG_CONFIG_ALLOW_CROSS=1
cargo build --release --target i686-unknown-linux-gnu
# output: target/i686-unknown-linux-gnu/release/libauxtools.so

Windows:

cargo build --release --target i686-pc-windows-msvc
# output: target/i686-pc-windows-msvc/release/auxtools.dll,debug_server.dll,auxcov.dll

For when BYOND is not enough. Probably often.
