Open-source Automated Programming Assistant

Website :: Knowledge Base :: Roadmap


Source++ is an open-source automated programming assistant with runtime-aware and context-aware functionality. Source++ is an observant-only programming assistant and aims to bridge application performance management (APM) solutions with the software developer's integrated development environment (IDE), enabling tighter feedback loops.

Source++ will not write source code for you. Source++ can be used to help debug and prevent runtime issues by providing contextualized behavior about your source code throughout development. Future versions of Source++ aspire to provide additional AI-based pair programming features.


  1. To enable developers easy access to feedback-driven development methodologies
  2. APMs often lack tight integration with actual development of the source code they monitor
  3. Source code comprehension can be improved by providing an extra dimension of behavior linked with said source code (ie. being able to visualize how a particular method acts in certain environments vs. locally)
  4. No websites or dashboards necessary to debug complex asynchronous runtime issues (just look at and follow through your actual source code)
  5. AI-based pair programming is going to be pretty cool when we get it right

Architectural Overview

Getting Started


  • Supported APMs: Apache SkyWalking
  • Supported IDEs: JetBrains
  • Supported OSes: Linux, macOS, and Windows


Downloading the IDE

Install a JetBrains IDE if you don’t already have one.

Install the Source++ Plugin

  1. Press Ctrl+Alt+S to open the Settings dialog and then go to Plugins.
  2. Click the Install JetBrains plugin.
  3. In the dialog that opens, search for SourcePlusPlus (direct link).
  4. Press Install.
  5. Click OK in the Settings dialog and restart your IDE.

After installation, you will need to configure the Source++ Plugin (see Configure Plugin).

Code Structure

Module Description Language
:agent:jvm-agent Used to activate and configure APMs' JVM agents Java 8+
:api Holds common data models and communication clients Java 8+
:core Handles integrations, contextualization, & subscriptions Groovy 2.4+
:plugin:jetbrains-plugin JetBrains implementation of the Source++ Plugin Groovy 2.4+
:portal Used to visually display contextualized artifact data Groovy 2.4+


Run all Source++ tests:

./gradlew test

Build Source++ Agent:

./gradlew buildAgent

Build Source++ Plugin:

./gradlew buildPlugin

Run Source++ Core (in Docker):

./gradlew runCore

Run Source++ Plugin (in JetBrains IDE):

./gradlew runIde
