cpp_project

Template for a modern C++ project using CMake.

Read through both the README and the justfile to better understand how everything works.

Notes

• Only Linux is supported
• All justfile commands should be run under a shell in which your .bashrc, .zshrc or equivalent has been sourced. Do not use the run button in your IDE, pyenv will likely not work.

Clone

git clone --recurse-submodules https://github.com/rdong8/cpp_project.git
cd cpp_project/

Dependencies

System

This recipe uses dnf and snap to install dependencies of this project. You may need to modify the command for your distro.

just system-deps

Python

First ensure you have pyenv and pyenv-virtualenv installed. Then:

just py-deps

Conan

Profile

Check if you already have a Conan profile with conan profile list. If you haven't already made one, create one:

just conan-profile

Then, modify the $(conan config home)/profiles/default profile generated to add a [buildenv] section, and put in your compiler and language details:

[buildenv]
CC = clang
CXX = clang++

[settings]
arch = x86_64
build_type = Release
compiler = clang
compiler.cppstd = 23
compiler.libcxx = libc++
compiler.version = 18
os = Linux

Note that the build type here is for your dependencies, which you can compile in release mode even if you are building your own code in debug. A variable conan_build_type is provided in the justfile to override the build type.

Build Dependencies

Now build the project's C++ dependencies with Conan:

just conan-deps

Configure

First, go in the justfile and set the paths to the C and C++ compilers.

Then either run:

just cmake-config

or create a CMake profile in CLion with the following settings:

• Name: Debug
• Build type: Debug
• Toolchain: Use Default
• Generator: Ninja Multi-Config
• CMake options:

  -G "Ninja Multi-Config" -DCMAKE_TOOLCHAIN_FILE=build/Debug/generators/conan_toolchain.cmake
  

• Build directory: build/
• Build options: empty
• Environment: empty

Build

To build the default target with the default arguments specified in the justfile:

just build

To build a specific target:

just build docs

Run

To run the default target with the default arguments specified in the justfile:

just run

To run a specific target:

just run cpp_project

To run a target with arguments:

just run cpp_project arg1 arg2 arg3

Docs

To open the documentation (must be built first via just build docs):

just docs

To open with a particular browser, pass the path to the command that will be passed the index.html file of the browser:

just docs firefox
just docs "flatpak run com.brave.Browser" # You need to use Flatseal to give the flatpak permission in this case

Test

just test

Pre-Commit

While developing, you may want to have some tasks automatically run with pre-commit.

just pre-commit

Clean

Cleans the build directory.

just clean

You'll need to make the project's Conan dependencies and run the CMake config again with just conan-deps cmake-config.
