#Development Environment

One of the most important features during application development is the ability to debug your code easily. Because of the asynchrnous nature, a standard Node.js application server works single-threaded by default. When you are developing applications using an IDE like Visual Studio Code, you can very easily debug your Node.js process:

First, download the free Visual Studio Code IDE (@code) and install it on your development machine.

The ObjectScript language of InterSystems IRIS has a very powerful metadata engine called XData. This feature allows the creation of metadata definitions for your classes, to be used by the compiler or by programs that will extend the standard features of the language, based on the XData definitions of its scope.

The latest release of Serenji focuses on the debug experience. Not only can you now debug on the spot, no matter where you are or what you're doing, but we've also added some smaller features that will make debugging more straightforward. 

• Run and Debug CodeLenses - clickable links above each class method, procedure, subroutine or extrinsic function.
• Intuitive prompting for entrypoints and arguments - when debugging a class method, produce, subroutine or extrinsic function. 
• Shaded read-only background - to clearly differentiate between documents which are editable and those that are read-only. 
• Program output in debug console - output is shown in the debug console. 
• Serenji commands on Server Manager's namespace trees - allowing you to launch Serenji through Server Manager.

Our gj :: codeSpex extension for VS Code, which is part of the DX Jetpack, allows documentation to be displayed inline while you are coding classes. In some cases the documentation is extensive, and the lack of scrolling support in the VS Code comment element we are using was degrading the DX.

We just faced an issue of the Atelier main menubar being disabled (greyed out) after upgrading the macOS development machine to High Sierra. I would like to share my findings about the issue and how to fix it.

This seems to be a known problem affecting several Java applications including Eclipse if the macOS user's primary language is not English: https://www.eclipse.org/org/press-release/20170925criticalbug.php

Hi developers,

We're hosting a User Group session for our Deltanji source control and Serenji debugger users on Wednesday, November 3rd at 11-12pm EDT / 3-4pm GMT.

We'll be showcasing some advanced features of Deltanji and Serenji in VS Code with time for a discussion - so feel free to bring along any problems you need help solving or share your feedback on our tools. We'd love to hear your thoughts.

You can find out more on Eventbrite.

Everyone is welcome. If you're interested in our tools this is a great chance to hear what others have to say, as well as asking your own questions.

We hope to see you on November 3rd!

I wrote a step by step tutorial in the qewd-howtos repository how you can write state of the art multi-page web apps with Node.js using a QEWD-Up WebSocket/REST api back-end integrated with a mainstream web framework like NuxtJS & Vue.js.

Allow limited durability for demo and development IRIS-Docker-micro-Durability During development of a container based demo I found the need to access a fresh docker
an instance of IRIS image (e.g intersystems/iris-community:2020.2.0.199.0) over and over.
To bypass loading my code repeatedly I developed this workaround.

It is a reduced variant of Docker - light weight durability

Visual Studio Code releases new updates every month with new features and bug fixes, and the January 2025 release is now available.

Looking for a fast, efficient IDE for developing ObjectScript code?

Check out ObjectScript with Visual Studio Code, a new video from Online Learning, which shows how to export ObjectScript packages from the InterSystems IRIS server and write ObjectScript classes and methods with Visual Studio Code.

I have been developing this project for many years. He helps me a lot in my daily work as a DBA and full stack developer.
This project has grown into a platform on which many of my other projects are based.
You can read more about the project in the article.
And I proposed this project for the contest, maybe it will be useful to you.

We’ve published an update to the Serenji debug extension for Visual Studio Code, making it ready for the Workplace Trust feature in VS Code 1.57.

This allows the Serenji ObjectScript editor to work without restrictions across all workspaces and, by bringing it in line with the VS Code update, only allows the debugging feature to be used in trusted workspaces.

The Atelier update site domain has changed from artifactoryonline.com to jfrog.io. JFrog Artifactory Cloud has deprecated the artifactoryonline.com domain in favor of jfrog.io. See their announcement for more details.

gj :: locate was the entry from George James Software for the Developer Tools competition back in April 2021. When an ObjectScript error is reported, gj :: locate takes the .int line location and navigates you directly to the line in the source file where the error originated. Over the past few months we've found it a very useful tool when it comes to debugging, especially when used alongside the Serenji debugger in Visual Studio Code.

Our first update, version 1.1.0, now includes support for multi-root workspaces. This enables gj :: locate to be used with every workspace folder. If your VS Code workspace has more than one root level folder, connecting to different namespaces or perhaps different servers, then gj :: locate will determine which workspace folder is current and locate the source code in that folder. If your workspace doesn't have any files open then gj :: locate will prompt you to select a folder from a pick-list.

This will particularly benefit VS Code power users who have workspaces with simultaneous connections to multiple namespaces, on multiple different IRIS and Caché servers.

If you would like to try it out then you can download it from the VS Code marketplace. Or if you’re already a user, then gj :: locate will automatically update. Let us know how you're getting on with it!
