Violet is a C++26 library that extends C++'s standard library with better enriching types and provide a common framework for building C++ applications from the ground up without much effort. Violet was made to help develop our projects to bridge common code between our products and services using C++ a lot easier.

The goal of Violet is to provide a enriched version of C++'s standard library by enhancing types that are pretty finicky (std::expected, std::optional) and providing new types and libraries (because let's face it, C++ iterators and ranges suck).

Violet aims to be buildable on most popular C++ build systems, which include:

• Bazel 7.6 or higher
• CMake 3.25 or higher
• Meson 1.1 or higher

and the following compilers:

• Clang 20 or higher
• GCC 14 or higher

Violet also supports C++ 20 or higher.

Using Violet in Bazel is the most trivial and most supported build system as we use Bazel extensively at Noelware. We only support Bzlmod and not the legacy WORKSPACE system.

We also aim to have Violet avaliable on BCR soon.

bazel_dep(name = "violet", version = "25.11") # you can pin `version` to what .violet-version says
git_override(
    module_name = "violet",
    remote = "https://github.com/Noelware/violet.git",
    commit = "<pinned commit here>"
)

CMake is officially supported as of Violet 25.11. It's not usually up-to-date since at Noelware, we use Bazel but we try to.

At the moment, we don't provide pkg-config recipes yet but you can use CMake's FetchContent:

FetchContent_Declare(
    violet
    GIT_REPOSITORY "https://github.com/Noelware/violet.git"
    GIT_TAG "<git tag here>"
)

# Disable installing for Violet
set(VIOLET_INSTALL OFF CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(violet)

Meson is not supported as of this current release. We have a basic meson.build but we won't add support unless necessary or if multiple people need support.
