eWam for Visual Studio Code

The official Visual Studio Code extension for eWam — bringing the power of model-driven development to your favorite editor.

eWam is a comprehensive development platform from Mphasis Wyde, featuring its own language (WAML), a powerful metamodel for data structures, seamless database integration, cloud-native capabilities, and REST API services.

Features

🔤 WAML Language Support

Full IDE support for WAML (Wyde Active Modeler Language):

Syntax highlighting for .wam files
Code completion with IntelliSense
Go to definition (F12) — navigate to entity declarations
Hover information — view entity details and documentation
Code formatting — automatic source code formatting
Document outline — navigate your code structure
Diagnostics — real-time error detection and reporting

📁 File-Based Development

Work with eWam projects using a file-based workflow (SCM - Source Code Management):

Organize your code in solutions, projects, and bundles
Edit .wam source files directly in VS Code
Manage projects and bundles through the Workspace view (with Add buttons)
Configure solutions with wam.solution.json
Configure projects with wam.project.json
Configure bundles with wam.bundle.json
Configure toolchain packages with wam.toolchain.json
Build bundles to push them to storage

Your source files are the source of truth, just standard files you can track with any version control system.

🐛 Advanced Debugging

Powerful debugging capabilities powered by the eWam Inspector API:

Attach to running processes — debug live applications
Step-by-step execution — step over, step into, step out
Breakpoints — set breakpoints in your WAML code
Call stack inspection — navigate through execution frames
Variable inspection — examine values at runtime
Data breakpoints — break when memory changes
Debug console commands — advanced inspection with CLI-style commands
Exception handling — configure break-on-error behavior
Multi-threaded debugging — debug complex concurrent applications

📊 Diagnostic Tools

Additional tools for monitoring and analysis:

Traces viewer — open and analyze .wamt trace files (supports folder watching)
Memory monitoring — track memory usage of running processes

Getting Started

Requirements

Node.js — for the eWam environment installer
eWam engine — version 8.x or later

Installation

Install this extension from the VS Code Marketplace, then follow the Get Started walkthrough that opens automatically.

The walkthrough guides you through:

Creating your eWam environment
Starting the eWam engine
Enhancing with wam.ai (optional AI integration)

You can reopen the walkthrough anytime from Help > Open Walkthrough... > eWam.

Debugging Your Application

Start debugging with F5 — the launch configuration is already set up by the installer.
You can also use launch.json snippets to create custom debug configurations.

Run Environment Variables

Set ewam.debug.launchEnv in your workspace settings to use environment variables with Run and debug launches without affecting the IDE engine. For example:

{
	"ewam.debug.launchEnv": {
		"WAM_DEBUGGER_MEMOPT": "padding"
	}
}

Keep shared settings in .env and run-only settings here. Individual launch configurations can override these values with env.
