cmakefmt

A Rust replacement for cmake-format.

Before

CMAKE_MINIMUM_REQUIRED(VERSION 3.20)
Project(myproject LANGUAGES CXX)

set(SOURCES src/main.cpp
src/utils.cpp
  src/parser.cpp)

target_link_libraries(mylib PUBLIC
Boost::filesystem Boost::system    fmt::fmt
  PRIVATE
    spdlog::spdlog)

IF(WIN32)
MESSAGE(STATUS "building on Windows")
ENDIF()

After $ cmakefmt -i CMakeLists.txt

cmake_minimum_required(VERSION 3.20)
project(myproject LANGUAGES CXX)

set(SOURCES src/main.cpp src/utils.cpp src/parser.cpp)

target_link_libraries(
  mylib
  PUBLIC Boost::filesystem Boost::system fmt::fmt
  PRIVATE spdlog::spdlog)

if(WIN32)
  message(STATUS "building on Windows")
endif()

On average 100× faster than cmake-format, with 150+ command specs audited against CMake 4.3. Ships an LSP server with format-on-save support in VS Code, Neovim, Helix, Zed, and Emacs, plus workflow flags (--check, --diff, --staged, --explain) for editor and CI use. Distributed as a single dependency-free binary; no Python toolchain required.

oomph-lib build system

Modern CMake migration of a 1M+ line C++ finite element library.

Replaced the legacy Autotools stack with a modern CMake build that's cleaner to contribute to, faster to configure, and easier to keep third-party dependencies up to date. Most of the work landed in a few months; iterative refinement continued for years after as the surrounding ecosystem matured.
