TigerBeetle C++ client (Header only)

TigerBeetle is a financial accounting database designed for mission critical safety and performance to power the future of financial services.

Prerequisites

C++ version: 20

Libraries

• fmtlib v11.0
• TigerBeetle C client library (latest version - branch main)

Tools

• cmake v3.14 or higher
• zig v0.13.0 (tigerbeetle compatible)

How to Build and Run

Another C++ toolchain

$> cmake -B build # (tb_client.[a|lib])
# OR
$> cmake -B build -DTIGERBEETLE_BUILD_SHARED_LIBS=ON # (tb_client.[so|dll|dylib])
# Build and test - build client examples
$> cmake --build build -DBUILD_EXAMPLES=ON --target run_with_tb # run TigerBeetle server + your client 

Zig toolchain

# Linux/MacOS
$> cmake -B build -DCMAKE_CXX_COMPILER=scripts/zigcxx.sh
# Windows
$> cmake -B build -DCMAKE_CXX_COMPILER=scripts/zigcxx.cmd

How to use

• Add on your cmake project:

include(FetchContent)

find_package(TigerBeetle 0.3.1 QUIET)
if (NOT TigerBeetle_FOUND)
    FetchContent_Declare(TigerBeetle GIT_REPOSITORY https://github.com/kassane/tigerbeetle-cpp.git
        GIT_TAG main)
    FetchContent_GetProperties(TigerBeetle)
# required
    set(APP_TARGETS ${PROJECT_NAME}) # executable or executables (need foreach) names
# optional
#   set(TB_VERSION 0.13.137) # tigerbeetle branch/tag repo (default: main)
#   set(TB_ADDRESS 3000) # tb_server port (default: 3001)
    FetchContent_MakeAvailable(TigerBeetle)
endif()

# linking your app to tb_client library
target_link_libraries(${PROJECT_NAME}
    PRIVATE tb_client
)
target_include_directories(${PROJECT_NAME} PUBLIC ${TigerBeetle_SOURCE_DIR}/include)
target_link_directories(${PROJECT_NAME} PUBLIC ${TigerBeetle_BINARY_DIR})

Note: zig c++ equal to clang++ -stdlib=libc++ -fuse-ld=lld for all targets (builtin), except to MacOS target, replacing lld to zld!!

TODO

• zig 0.11.0 - missing zig-pkg (choose cmake or zig only) to c_client support.

Frequently Asked Questions

Do I need to install Zig to compile this project?

A: No! You can use the C and/or C++ compiler of your choice.

However, as mentioned in issue #3, it will only be possible to link dynamically. The Zig static library does not include compiler-rt library, it only includes executables and shared libraries.

• undefined reference to __zig_probe_stack - Fixed.

It is also not limited to C++, you just need to modify the CMakeLists.txt to use it with other languages supported by CMake.

:information_source: CMake: Supported languages are C, CXX (i.e. C++), CSharp (i.e. C#), CUDA, OBJC (i.e. Objective-C), OBJCXX (i.e. Objective-C++), Fortran, HIP, ISPC, Swift, ASM, ASM_NASM, ASM_MARMASM, ASM_MASM, and ASM-ATT.

See: cmake docs

Is this project an official binding for TigerBeetleDB?

A: No! It's only a community project. But there's nothing stopping the main developers from porting it to the official repository if they want to.

What is the goal of tigerbeetle-cpp?

A: Firstly, to provide a simple C++ solution derived from the C binding (thanks to @batiati).

Also, to demonstrate that it's possible to use Zig with CMake to build the tb_client library without the user needing to use the Zig toolchain (C and/or C++). They don't even need to learn it if they don't want to. (I suggest reconsidering this matter!!)

Another important point is that TigerBeetle is a product in the early stages of development, subject to flaws and mistakes. The best way to improve this new tool is by testing, and that's where the relevance of the clients (language bindings) comes into play.
