cmake-start 1.0.1

The missing CMake project initializer

cmake-init

🚀 Generate modern CMake projects with best practices built-in

Powered by UV - the fast Python package manager.

Quick Start

# 1. Install UV
curl -LsSf https://astral.sh/uv/install.sh | sh

# 2. Clone & Setup
git clone https://github.com/Guo-astro/cmake-start.git
cd cmake-start
./tasks.sh setup

# 3. Create a project
uv run cmake-init my-project

# 4. Build it
cd my-project
cmake --preset=dev
cmake --build --preset=dev

---

Usage

# C++ executable (default)
uv run cmake-init my-app

# C++ library
uv run cmake-init -s my-lib

# C++ header-only library
uv run cmake-init -h my-headers

# C project
uv run cmake-init --c my-c-app

# C++20 standard
uv run cmake-init --std 20 my-modern-app

# With Conan/vcpkg
uv run cmake-init -p conan my-app

Important: Project names must be lowercase (e.g., my-project, not MyProject)

Installing Code Quality Tools (Optional)

These tools are auto-detected - your project will build fine without them, but they provide extra code checking:

clang-tidy

# macOS
brew install llvm

# Ubuntu/Debian
sudo apt install clang-tidy

# Fedora
sudo dnf install clang-tools-extra

# NixOS
nix-env -iA nixpkgs.clang-tools

# Windows
choco install llvm

cppcheck

# macOS
brew install cppcheck

# Ubuntu/Debian
sudo apt install cppcheck

# Fedora
sudo dnf install cppcheck

# NixOS
nix-env -iA nixpkgs.cppcheck

# Windows
choco install cppcheck

When you run cmake --preset=dev, you'll see:

-- Found clang-tidy: /path/to/clang-tidy
-- Found cppcheck: /path/to/cppcheck
-- Code quality tools status:
--   clang-tidy: ON
--   cppcheck:   ON

If tools aren't found, they're automatically disabled with installation instructions.

Making Changes

# 1. Edit source files
vim cmake-init/cmake_init.py
vim cmake-init/templates/common/cmake/code-quality.cmake

# 2. Rebuild (copies files + creates template ZIP)
python build.py

# 3. Test
uv run cmake-init test-project

Single source of truth: Always edit files in cmake-init/, then run python build.py

Common Issues

"ModuleNotFoundError"

./fix-editable.sh

"Changes not working"

python build.py  # Run after editing cmake-init/

"Invalid project name"

# Bad:  uv run cmake-init MyProject
# Good: uv run cmake-init my-project

NixOS build errors

export CXX=clang++
cmake --preset=dev

---

Releasing to PyPI

# Quick release (patch/minor/major)
python release.py patch  # 0.42.0 → 0.42.1

# See RELEASE.md for full documentation

The script handles: version bump, build, git tag, PyPI publish, and GitHub push.

What Makes This Different?

✅ Auto-detects clang-tidy and cppcheck - no build failures
✅ Latest vcpkg - automatically fetches current baseline hash
✅ Fast - powered by UV (10-100x faster than pip)
✅ Modern - CMake presets, FetchContent-ready
✅ Developer-friendly - helpful error messages
✅ Cross-platform - macOS, Linux, Windows, NixOS
✅ Single source - edit cmake-init/, run build.py
