Use VS Code to manage and build C/C++ projects using the xPack tools.
Edit

Features

Manage typical multi-configuration projects (like Debug/Release), but also complex, multi-platform, multi-architecture, multi-toolchain projects, with an emphasis on modern C/C++ and embedded applications.

This open source project is available on GitHub and is part of he xPack Project.

In VS Code it can be directly installed from the Visual Studio Code Marketplace

This extension is intended as a future replacement for the managed build system available in Eclipse Embedded CDT.

Requirements

Quick Start

TL;DR: ViewCommand Palette…xPack: Quick Start a Hello World project (C++, CMake) (but better read the web page).

The easiest way to start with the VS Code xPack C/C++ Managed Build extension is to create the classical Hello World project.

Follow the steps in the Quick Start page. In addition to being a fully functional project, the result will also be a good starting point for more complex projects.

How it works

The xPack Managed Build is neutral to the build system, and basically can invoke any tools, old and new, but favours modern tools (like CMake and meson) which can generate a compile_commands.json file, since this greatly simplifies the project IntelliSense configuration.

Disclaimer

Concepts (configurations & actions)

Compared to typical CMake/meson projects, which in most cases are reduced to a single build folder, an xPack Managed Build project is by design defined as

a collection of named build configurations

each using a separate build folder, and

each with its own set of named actions

defined as sequences of commands (stored in JSON as arrays of string).

xPack Actions

To avoid redundant definitions between configurations, the actions can use generic templates, with substitutions performed by the LiquidJS template engine, based on user defined string properties.

A typical example of a project with two build configurations, using CMake, may look like:

{
  "name": "hello-world",
  "version": "0.1.0",
  "description": "A Hello World project",
  "main": "",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

  },
  "xpack": {
    "properties": {
      "buildFolderRelativePath": "build{% if os.platform == 'win32' %}\\{% else %}/{% endif %}{{ configuration.name | downcase }}",

          "build": [
            "{{ properties.commandPrepare }}",
            "{{ properties.commandBuild }}"
          ],
          "clean": "{{ properties.commandClean }}",
          "execute": "{{ properties.commandExecuteHello }}"
        }
      },
      "Release": {
        "properties": {
          "buildType": "Release"
        },
        "actions": {

          "build": [

            "{{ properties.commandBuild }}"
          ],
          "clean": "{{ properties.commandClean }}",
          "execute": "{{ properties.commandExecuteHello }}"
        }
      }
    }
  }
}

With the help of xpm, the complete cycle of prepare/build/execute can be invoked via:

cd <project>
xpm install
xpm run test

Note: this example assumes the presence of a toolchain, like GCC or clang.

Release Notes

The latest release is v0.x, which, according to semantic versioning rules, means it is in initial development phase.

The xPack extension is functional and can be used for beta-testing, but anything MAY change at any time and the public API SHOULD NOT be considered stable.

More details about each release can be found in the releases pages.
