From dcd76fd3e1073155fce7c7cd00bf9a2ba32295fc Mon Sep 17 00:00:00 2001 From: heinrich5991 Date: Wed, 19 Oct 2022 23:46:06 +0200 Subject: [PATCH] Add support for Rust code in DDNet The glue is done using the [cxx crate](https://cxx.rs/) on the Rust side. As a proof-of-concept, only a small console command (`rust_version`) printing the currently used Rust version was added. You can generate and open the Rust documentation using `DDNET_TEST_NO_LINK=1 cargo doc --open`. You can run the Rust tests using `cmake --build --target run_rust_tests`, they're automatically included in the `run_tests` target as well. Rust tests don't work on Windows in debug mode on Windows because Rust cannot currently link with the debug version of the C stdlib on Windows: https://github.com/rust-lang/rust/issues/39016. --- The stuff in `src/rust-bridge` is generated using ``` cxxbridge src/engine/shared/rust_version.rs --output src/rust-bridge/engine/shared/rust_version.cpp --output src/rust-bridge/engine/shared/rust_version.h cxxbridge src/engine/console.rs --output src/rust-bridge/cpp/console.cpp --output src/rust-bridge/cpp/console.h ``` --- .cargo/config.toml | 2 +

You also need to install [Rust](https://rustup.rs/). Start CMake and select the source code folder (where DDNet resides, the directory with `CMakeLists.txt`). Additionally select a build folder, e.g. create a build subdirectory in the source code directory. Click "Configure" and select the Visual Studio generator (it should be pre-selected, so pressing "Finish" will suffice). After configuration finishes and the "Generate" reactivates, click it. When that finishes, click "Open Project". Visual Studio should open. You can compile the DDNet client by right-clicking the DDNet project (not the solution) and select "Select as StartUp project". Now you should be able to compile DDNet by clicking the green, triangular "Run" button. diff --git a/cmake/FindRust.cmake b/cmake/FindRust.cmake new file mode 100644 index 000000000..9c2bf7ca7 --- /dev/null +++ b/cmake/FindRust.cmake @@ -0,0 +1,29 @@ +find_program(RUST_RUSTC rustc) +find_program(RUST_CARGO cargo) + +if(RUST_RUSTC) + execute_process(COMMAND ${RUST_RUSTC} --version --verbose OUTPUT_VARIABLE RUSTC_VERSION_OUTPUT) + string(REPLACE "\n" ";" RUSTC_VERSION_OUTPUT "${RUSTC_VERSION_OUTPUT}") + set(RUST_NIGHTLY OFF) + foreach(line ${RUSTC_VERSION_OUTPUT}) + if(NOT DEFINED RUST_VERSION_STRING) + set(RUST_VERSION_STRING ${line}) + endif() + if(line MATCHES "^([^:]+): (.*)$") + set(KEY ${CMAKE_MATCH_1}) + set(VALUE ${CMAKE_MATCH_2}) + if(KEY STREQUAL "release") + set(RUST_VERSION ${VALUE}) + if(VALUE MATCHES "nightly") + set(RUST_NIGHTLY ON) + endif() + elseif(KEY STREQUAL "host") + set(RUST_TARGET_HOST ${VALUE}) + endif() + endif() + endforeach() +endif() + +include(FindPackageHandleStandardArgs) +find_package_handle_standard_args(Rust DEFAULT_MSG RUST_RUSTC RUST_CARGO) +mark_as_advanced(RUST_RUSTC RUST_CARGO) diff --git a/cmake/toolchains/Emscripten.toolchain b/cmake/toolchains/Emscripten.toolchain index 0ed57443b..09c75e0b9 100644 --- a/cmake/toolchains/Emscripten.toolchain +++ b/cmake/toolchains/Emscripten.toolchain @@ -35,3 +35,4 @@ set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread -D_REENTRANT -g -O3 ${WASM_CXX_ set(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS} -pthread -D_REENTRANT -g -O3 ${WASM_CXX_ENGINE_FLAGS}") set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -pthread ${WASM_ENGINE_FLAGS}") set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} ${WASM_ENGINE_FLAGS}") +set(CMAKE_RUST_COMPILER_TARGET wasm32-unknown-emscripten) diff --git a/cmake/toolchains/darwin-arm64.toolchain b/cmake/toolchains/darwin-arm64.toolchain index 2801912cd..cc3ee909b 100644 --- a/cmake/toolchains/darwin-arm64.toolchain +++ b/cmake/toolchains/darwin-arm64.toolchain @@ -11,6 +11,7 @@ set(CMAKE_C_COMPILER oa64-clang) set(CMAKE_CXX_COMPILER oa64-clang++) set(CMAKE_INSTALL_NAME_TOOL aarch64-apple-$ENV{OSXCROSS_TARGET}-install_name_tool) set(CMAKE_OTOOL aarch64-apple-$ENV{OSXCROSS_TARGET}-otool) +set(CMAKE_RUST_COMPILER_TARGET aarch64-apple-darwin) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) diff --git a/cmake/toolchains/darwin-x86_64.toolchain b/cmake/toolchains/darwin-x86_64.toolchain index d6824e772..f4a7ec3b1 100644 --- a/cmake/toolchains/darwin-x86_64.toolchain +++ b/cmake/toolchains/darwin-x86_64.toolchain @@ -11,6 +11,7 @@ set(CMAKE_C_COMPILER o64-clang) set(CMAKE_CXX_COMPILER o64-clang++) set(CMAKE_INSTALL_NAME_TOOL x86_64-apple-$ENV{OSXCROSS_TARGET}-install_name_tool) set(CMAKE_OTOOL x86_64-apple-$ENV{OSXCROSS_TARGET}-otool) +set(CMAKE_RUST_COMPILER_TARGET x86_64-apple-darwin) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) diff --git a/cmake/toolchains/mingw32.toolchain b/cmake/toolchains/mingw32.toolchain index c4c065b7e..e920543d6 100644 --- a/cmake/toolchains/mingw32.toolchain +++ b/cmake/toolchains/mingw32.toolchain @@ -3,6 +3,7 @@ set(CMAKE_SYSTEM_NAME Windows) set(CMAKE_C_COMPILER i686-w64-mingw32-gcc) set(CMAKE_CXX_COMPILER i686-w64-mingw32-g++) set(CMAKE_RC_COMPILER i686-w64-mingw32-windres) +set(CMAKE_RUST_COMPILER_TARGET i686-pc-windows-gnu) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) diff --git a/cmake/toolchains/mingw64.toolchain b/cmake/toolchains/mingw64.toolchain index bec41e944..a43605b2a 100644 --- a/cmake/toolchains/mingw64.toolchain +++ b/cmake/toolchains/mingw64.toolchain @@ -3,6 +3,7 @@ set(CMAKE_SYSTEM_NAME Windows) set(CMAKE_C_COMPILER x86_64-w64-mingw32-gcc) set(CMAKE_CXX_COMPILER x86_64-w64-mingw32-g++) set(CMAKE_RC_COMPILER x86_64-w64-mingw32-windres) +set(CMAKE_RUST_COMPILER_TARGET x86_64-pc-windows-gnu) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) diff --git a/deny.toml b/deny.toml new file mode 100644 index 000000000..bb2881b17 --- /dev/null +++ b/deny.toml @@ -0,0 +1,6 @@ +[licenses] +allow = [ + "Apache-2.0", + "MIT", + "Zlib" +] diff --git a/scripts/check_header_guards.py b/scripts/check_header_guards.py index 4cd926c0f..275ee6e9d 100755 --- a/scripts/check_header_guards.py +++ b/scripts/check_header_guards.py @@ -6,9 +6,9 @@ os.chdir(os.path.dirname(__file__) + "/..")
