cmkr

cmkr, pronounced "cmaker", is A CMakeLists.txt generator from TOML.

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:

[cmake]
minimum = "3.15"

[project]
name = "app"
version = "0.1.0"

[[target]]
name = "app"
type = "executable"
sources = ["src/main.cpp"]

This project's cmake.toml:

[cmake]
minimum = "3.15"

[project]
name = "cmkr"
version = "0.1.3"

[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" }

[[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"

The cmkr executable can be run 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.

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 

Binary types

executable

Executable binary. Equivalent to add_executable(name).

library

Library, can be static or shared depending on the BUILD_SHARED_LIBS variable. Equivalent to add_library().

static

Static library/archive. Equivalent to add_library(name STATIC).

shared

Shared/dynamic library. Equivalent to add_library(name SHARED).

interface

Header-only library. Equivalent to add_library(name INTERFACE).

Roadmap

• Support more cmake fields.
• Support conditional cmake args somehow!
