OEDP – OpenEdge ABL Developer Pack

A curated VS Code extension pack for Progress OpenEdge ABL / 4GL developers — language support, snippets, tooling, and productivity extensions in one install.

Why this pack exists

It's mid-2026. Almost everyone is writing software either by hand or side-by-side with AI — and the pace is accelerating fast. The teams at the front of the curve have already moved past "AI autocomplete." They're orchestrating their work: describing issues, and letting humans and agents drive them to done together.

From manual coding to AI orchestration — four stages

In the OpenEdge world, that next step is still hard. Not because the language can't keep up, but because not all the tools are there yet to fully automate the workflow. Too much of the day still depends on manual, screen-by-screen work.

That's where we step in.

The tooling itself isn't missing — it just isn't available in VS Code and its forks yet. That's where phase 1 starts: bringing it into this environment.

Database administration
Database querying & browsing
PASOE management
UI design
Performance checks
Unit testing

Today, these tools live mainly in the UI, during development. The second stage brings them to developers working manually with AI agents inside VS Code and its forks, through the extensions in this pack.

But that's not the destination. The goal is to move away from the code itself and toward a project-management foundation — where humans and AI collaborate on described features, not lines of code. To get there, the OpenEdge ecosystem still has gaps we need to close.

By bringing these tools to VS Code and its forks now, we make their capabilities available to agents — and that unlocks stable, predictable, fully automated feature delivery for OpenEdge development.
