 # cmkr
 
-cmkr, pronounced "cmaker", is A CMakeLists.txt generator from TOML.
+`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:
 
-## Building
-cmkr requires a C++11 compiler, cmake >= 3.15.
-```
-git clone https://github.com/moalyousef/cmkr
-cd cmkr
-cmake -Bbin
-cmake --build bin --parallel
-```
-
-## Usage
-cmkr parses cmake.toml files (using toml11 by Toru Niina) at the project directory. A basic hello world format with the minimum required fields:
 ```toml
-[cmake]
-minimum = "3.15"
-
 [project]
-name = "app"
-version = "0.1.0"
+name = "cmkr_for_beginners"
 
-[[target]]
-name = "app"
+[target.hello_world]
 type = "executable"
 sources = ["src/main.cpp"]
 ```
 
-This project's cmake.toml:
-```toml
-[cmake]
-minimum = "3.15"
+`cmkr` can bootstrap itself from CMake and you only need CMake to use it.
 
-[project]
-name = "cmkr"
-version = "0.1.4"
-description = "CMakeLists generator from TOML"
+## Getting started
 
-[fetch-content]
-toml11 = { git = "https://github.com/ToruNiina/toml11" }
-filesystem = { git = "https://github.com/gulrak/filesystem" }
-mpark_variant = { url = "https://github.com/mpark/variant/archive/v1.4.0.tar.gz" }
+To get started run the following commands from your project directory:
 
-[[target]]
-name = "cmkrlib"
-type = "static"
-sources = ["src/cmake.cpp", "src/gen.cpp", "src/help.cpp", "src/build.cpp", "src/error.cpp"]
-include-directories = ["include"]
-compile-features = ["cxx_std_11"]
-link-libraries = ["toml11::toml11", "ghc_filesystem"]
-
-[[target]]
-name = "cmkr"
-type = "executable"
-sources = ["src/main.cpp", "src/args.cpp"]
-link-libraries = ["cmkrlib"]
-
-[[install]]
-targets = ["cmkr"]
-destination = "${CMAKE_INSTALL_PREFIX}/bin"
+```sh
+curl https://raw.githubusercontent.com/build-cpp/cmkr/main/cmake/cmkr.cmake -o cmkr.cmake
+cmake -P cmkr.cmake
 ```
 
-Currently supported fields:
-```toml
-[cmake] # required for top-level project
-minimum = "3.15" # required
-description = "" # optional
-subdirs = [] # optional
-build-dir = "build" # optional
-cpp-flags = [] # optional
-c-flags = [] # optional
-link-flags = [] # optional
-generator = "Ninja" # optional, only valid when run using: cmkr build
-config = "Release" # optional, only valid when run using: cmkr build
-arguments = ["CMAKE_TOOLCHAIN_FILE=/path/to/toolchain"] # optional, valid when run using: cmkr build
+After the bootstrapping process finishes, modify [`cmake.toml`](https://build-cpp.github.io/cmkr/cmake-toml) and open the project in your favorite IDE or build with CMake:
 
-[settings] # optional
-CMAKE_BUILD_TYPE = "Release"
-TOML_BUILD_TESTS = false # optional
-TOML_BUILD_DOCS = { value = false, comment = "builds dependency docs", cache = true, force = true } # optional
-OLD_VERSION = "0.1.1" # optional
-
-[project] # required per project
-name = "app" # required
-version = "0.1.0" # required
-
-[find-package] # optional, runs find_package, use "*" to ignore version
-Boost = { version = "1.74.0", required = false, components = ["system"] } # optional
-spdlog = "*"
-
-[fetch-content] # optional, runs fetchContent
-toml11 = { git = "https://github.com/ToruNiina/toml11", tag = "v3.5.0" } # optional
-
-[options] # optional
-APP_BUILD_STUFF = false # optional
-APP_OTHER_STUFF = { comment = "does other stuff", value = false } # optional
-
-[[target]] # required, can define several binaries
-name = "app" # required
-type = "executable" # required (executable || library || shared || static || interface)
-sources = ["src/*.cpp"] # required, supports globbing
-include-directories = ["include"] # optional
-alias = "" # optional
-compile-features = [] # optional
-compile-definitions = [] # optional
-link-libraries = [] # optional 
-properties = { PROPERTY1 = "property1", ... } # optional
-
-[[test]] # optional, can define several
-name = "test1" # required
-command = "app" # required
-arguments = ["arg1", "arg2"] # optional
-
-[[install]] # optional, can define several
-targets = ["app"] # optional
-files = ["include/*.h"] # optional
-dirs = [] # optional
-configs = [] # optional (Release|Debug...etc)
-destination = "${CMAKE_INSTALL_PREFIX}/bin" # required
+```sh
+cmake -B build
+cmake --build build
 ```
 
-The cmkr executable can be run from the command-line:
+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`.
+
+In CI settings the `cmkr` bootstrapping process is skipped so there is no extra configure-time 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:
@@ -133,28 +61,12 @@ arguments:

     version                                              Current cmkr version.

-The build command invokes cmake and the default build-system on your platform (unless a generator is specified), it also accepts extra cmake build arguments:
-```
-cmkr build --config Release 
-```

+# Reference
+
+This page is a reference for the options in the `cmake.toml` file. If you think anything is missing or unclear, please [edit this page](https://github.com/build-cpp/cmkr/edit/main/docs/cmake-toml.md) or open an [issue](https://github.com/build-cpp/cmkr/issues).
+
+See the [examples](/examples) section for concrete examples.
+
+## CMake configuration
+
+```toml
+[cmake]
+version = "3.15"
+cmkr-include = "cmkr.cmake"
+```
+
+## Project configuration
+
+```toml
+[project]
+name = "myproject"
+version = "1.0.0"
+description = "Description of the project"
+languages = ["C", "CXX"]
+cmake-before = """
+message(STATUS "CMake injected before the project() call")

+"""
+include-before = ["cmake/before-project.cmake"]
+include-after = ["cmake/after-project.cmake"]
+```
+
+## Conditions
+
+You can specify your own conditions and use them in any `condition` field:
+
+```toml
+[conditions]
+arch64 = "CMAKE_SIZEOF_VOID_P EQUALS 8"
+arch32 = "CMAKE_SIZEOF_VOID_P EQUALS 4"
+```
+
+This will make the `arch64` and `arch32` conditions available with their respective CMake expressions. 
+
+You can also prefix most keys with `condition.` to represent a conditional:
+
+```toml
+[target]
+type = "executable"
+sources = ["src/main.cpp"]
+windows.sources = ["src/windows_specific.cpp"]
+```
+
+The following conditions are predefined (you can override them if you desire):
+
+```toml
+[conditions]
+windows = "WIN32"
+macos = "CMAKE_SYSTEM_NAME MATCHES \"Darwin\""
+unix = "UNIX"
+bsd = "CMAKE_SYSTEM_NAME MATCHES \"BSD\""
+linux = "CMAKE_SYSTEM_NAME MATCHES \"Linux\""
+gcc = "CMAKE_CXX_COMPILER_ID STREQUAL \"GNU\" OR CMAKE_C_COMPILER_ID STREQUAL \"GNU\""
+clang = "CMAKE_CXX_COMPILER_ID MATCHES \"Clang\" OR CMAKE_C_COMPILER_ID MATCHES \"Clang\""
+msvc = "MSVC"
+root = "CMKR_ROOT_PROJECT"
+x64 = "CMAKE_SIZEOF_VOID_P EQUAL 8"
+x32 = "CMAKE_SIZEOF_VOID_P EQUAL 4"
+```
+
+## Subdirectories
+
+```toml
+[subdir.mysubdir]
+condition = "mycondition"
+cmake-before = """
+message(STATUS "CMake injected before the add_subdirectory() call"
+"""
+cmake-after = """
+message(STATUS "CMake injected after the add_subdirectory() call")
+"""
+include-before = ["cmake/before-subdir.cmake"]
+include-after = ["cmake/after-subdir.cmake"]
+```
+
+## Vcpkg
+
+```toml
+[vcpkg]
+version = "2021.05.12"
+url = "https://github.com/microsoft/vcpkg/archive/refs/tags/2021.05.12.tar.gz"
+packages = ["fmt", "zlib"]
+```
+
+The vcpkg `version` will automatically generate the `url` from the [official repository](https://github.com/microsoft/vcpkg/releases). For a custom registry you can specify your own `url` (and omit the `version`). You can browse available packages on [vcpkg.io](https://vcpkg.io/en/packages.html).
+
+To specify package features you can use the following syntax: `imgui[docking-experimental,freetype,sdl2-binding,opengl3-binding]`.
+

+required = true
+config = true
+components = ["mycomponent"]
+```
+
+## FetchContent
+
+**Note**: The `[fetch-content]` feature is unpolished and will likely change in a future release.
+
+```toml
+[fetch-content.gitcontent]

+CXX_STANDARD_REQUIRED = true
+FOLDER = "MyFolder"
+```
+
+## Tests and installation (unfinished)
+
+**Note**: The `[[test]]` and `[[install]]` are unfinished features and will likely change in a future release.
+
+```toml

+[[test]]
+condition = "mycondition"

+# Index
+
+`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 from CMake and you only need CMake 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, modify [`cmake.toml`](https://build-cpp.github.io/cmkr/cmake-toml) and open the project in your favorite IDE or build with 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`.
+
+In CI settings the `cmkr` bootstrapping process is skipped so there is no extra configure-time 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] Starts a new project in the same directory.
+    gen                                                  Generates CMakeLists.txt file.
+    build   <extra cmake args>                           Run cmake and build.
+    install                                              Run cmake --install. Needs admin privileges.
+    clean                                                Clean the build directory.
+    help                                                 Show help.
+    version                                              Current cmkr version.
+```
