ChakraCore-Debugger

ChakraCore-Debugger is a C++ companion library which enables the debugging of ChakraCore using the DevTools Protocol.

Features

• Enables drop-in support for debugging ChakraCore in host applications
• Supports Visual Studio Code and other compatible clients
• Exposes a C ABI for use by C99 consumers
• Flexibility to replace the transport service code to meet the needs of the host

Status

This project is still in active development, but ready for integration. Future work is tracked in the issue tracker.

Usage

Prerequisites

• Windows
• Visual Studio 2017
• Python 2.7 (For generating the protocol parser only; must be in the PATH)

Building

ChakraCore-Debugger depends on ChakraCore from NuGet. All other dependencies are header-only and included as submodules.

1. Clone the project (and submodules):

> git clone --recurse-submodules https://github.com/Microsoft/ChakraCore-Debugger

2. Launch the solution file:

> cd .\ChakraCore-Debugger\
> .\ChakraCore.Debugger.sln

3. Right-click the "ChakraCore.Debugger.Sample" project and click "Set as StartUp Project".
4. Choose the desired build configuration and platform (e.g. Debug - x64).
5. Right-click on the Solution in "Solution Explorer" and click "Restore NuGet Packages".
6. Set the debugger arguments in the "ChakraCore.Debugger.Sample" project to pass the startup parameters and the name of a script to run (e.g. --inspect-brk --port 9229 test.js).
7. Hit F5 to start debugging.

Connecting

Connect to the sample application using Visual Studio Code.

1. Navigate to a working folder and launch Visual Studio Code:

> pushd <working folder>
> code .

2. Switch to the "Debug (Ctrl+Shift+D)" panel and click the "Configure or Fix 'launch.json'" gear button.
3. Select the "Node.js" environment.
4. Add a new configuration:

{
    "type": "node",
    "request": "attach",
    "name": "Attach",
    "port": 9229,
    "protocol": "inspector"
}

5. Save the "launch.json" file and click the "Start Debugging" play button.
6. Execution should break on the first line of the script.
