# Documentation
|
|
|
|
[`cmkr`](https://github.com/build-cpp/cmkr), pronounced "cmaker", is a modern build system based on [CMake](https://cmake.org/) and [TOML](https://toml.io).
|
|
|
|
`cmkr` parses `cmake.toml` files and generates a modern, idiomatic `CMakeLists.txt` for you. A minimal example:
|
|
|
|
```toml
|
|
[project]
|
|
name = "cmkr_for_beginners"
|
|
|
|
[target.hello_world]
|
|
type = "executable"
|
|
sources = ["src/main.cpp"]
|
|
```
|
|
|
|
`cmkr` can bootstrap itself, and you only need CMake and a C++ compiler to use it.
|
|
|
|
## Getting started
|
|
|
|
To get started, run the following commands from your project directory:
|
|
|
|
```sh
|
|
curl https://raw.githubusercontent.com/build-cpp/cmkr/main/cmake/cmkr.cmake -o cmkr.cmake
|
|
cmake -P cmkr.cmake
|
|
```
|
|
|
|
After the bootstrapping process finishes, customize [`cmake.toml`](./cmake-toml) for your project and run CMake:
|
|
|
|
```sh
|
|
cmake -B build
|
|
cmake --build build
|
|
```
|
|
|
|
Once bootstrapped, `cmkr` does not introduce extra steps to your workflow. After modifying `cmake.toml` you simply build/configure your CMake project and `cmkr` will automatically regenerate `CMakeLists.txt` when necessary.
|
|
|
|
<sub>**Note**: The `cmake.toml` project file, generated `CMakeLists.txt` and `cmkr.cmake` bootstrapping script are all intended to be added to source control.</sub>
|
|
|
|
In CI environments the `cmkr` bootstrapping process is skipped, so there is no additional overhead in your pipelines.
|
|
|
|
## Template repositories
|
|
|
|
Another way to get started is to use the [cmkr_for_beginners](https://github.com/build-cpp/cmkr_for_beginners) template repository. Either open it in [Gitpod](https://gitpod.io/#https://github.com/build-cpp/cmkr_for_beginners), or clone the repository and run:
|
|
|
|
```sh
|
|
cmake -B build
|
|
cmake --build build
|
|
```
|
|
|
|
Check out the [cmkr topic](https://github.com/topics/cmkr), the [build-cpp organization](https://github.com/build-cpp) or the [tests](https://github.com/build-cpp/cmkr/tree/main/tests) for more examples and templates.
|
|
|
|
## Command line
|
|
|
|
Optionally you can put a [`cmkr` release](https://github.com/build-cpp/cmkr/releases) in your `PATH` and use it as a utility from the command line:
|
|
|
|
```
|
|
Usage: cmkr [arguments]
|
|
arguments:
|
|
init [executable|library|shared|static|interface] Create a project.
|
|
gen Generates CMakeLists.txt file.
|
|
build <extra cmake args> Run cmake and build.
|
|
install Run cmake --install.
|
|
clean Clean the build directory.
|
|
help Show help.
|
|
version Current cmkr version.
|
|
```
