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.

The most recent release of Serenji features our innovative gj::locate technology. It was a standalone tool we originally created for a Developer Community contest earlier this year, but we've incorporated it into our debugger after some great feedback from developers. 

It works by navigating you directly to the source of your server-side errors in just a couple of clicks - enabling you to quickly fix errors without the need to count tedious lines of code... and let's be real, who has got time for that when you're under pressure to fix this bug? 

It's simple and straightforward to use:

1. Click on the gj::locate panel in the status bar

2. Enter the ObjectScript error message or line reference from a class/.mac routine..

3. gj::locate then does the work for you by taking you straight to the corresponding line in your source code.

Easy peasy... and with time to spare to make yourself a coffee before your deadline! 

The video below shows it in action - let us know if you've already given it a go. Or, if you're interested in trying it out we offer a free 30 day trial license, just drop me a message through the Developer Community or email us at info@georgejames.com.

Hi developers, 

Serenji 3.2.0, the latest version from George James Software, was released last week and our current users have been enjoying trying out the new features (which you can find more about here). 

If you're thinking about trying Serenji for the first time, we've made it easier to get set up by adding a walkthrough on the VS Code Welcome page. It takes you through: 

  • Setting up the server components.
  • Selecting a server namespace.
  • Saving and extending your workspace.
  • Requesting a debug license (don't forget we offer a free 30 day trial!) 

We've also added prompts and guidance throughout VS Code to open and add Serenji folders to your workspace and when going to run and debug code. 

This is just one of the ways we've enhanced the Serenji debugger to make straightforward and easy to use - so all you need to do is focus on your code.

Zero configuration debugging

The latest release of Serenji by George James Software introduces zero configuration debugging, so it's ready to go in just one click - no matter where you are or what you're doing, your on-the-spot debugger is ready to go. 

We have introduced a host of new features to enhance the debugging experience so you can focus on identifying and fixing errors, without losing focus by spending time setting up a launch configuration.

Hi folks!

Want to share a lifehack with you on ObjectScript highlighiting withing VSCode for script files.

Script files are just files with lines of ObjectScript that we feed anywhere, e.g. into IRIS during Docker baking procedure.

Typical usecase - here is the Scriptfile

here is the Dockerfile where we feed it.

And here is how it looks like usually in VSCode:

Why gj :: locate?

You may think it isn’t too difficult to get from label+offset^routine to the actual source line responsible for the error. For an expert it isn't that hard... most of the time. But there are enough oddities and special rules that even an expert can get it wrong, whilst spending a lot of time trying to get there.

gj :: locate is the latest tool from George James Software – it debugs any error, class or routine by converting the location of an error in compiled .int code to the corresponding location in your source, and then taking you right there.

Image this scenario…

In Studio you could open a class directly via it's name, without having to traverse the package tree with multiple clicks until arriving at the desired class.

You would Ctrl + O or (File -> Open) and be able to simply type in the class name, for example:

You press Enter, and viola - the class is opened.

How do you achieve this in VSCode?

Moving over from Studio To VSCode like many other will do now the ObjectScript plugin reached version 1.0, I noticed I was missing some items in the objectscript explorer. For example when creating a Rest API using the spec first approach, 3 classes are generated, an application.impl, application.disp and application.spec class, but the disp class was missing in the Object Explorer.

As the application.disp is a generated class, for showing these classes you need to turn this on by hitting the switch on the object explorer:

Access to IRIS from Rust

What do you think If I will say you, that very soon you will be able to connect to IRIS from the application written in Rust.

What is Rust

Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but can guarantee memory safety by using a borrow checker to validate references. Rust achieves memory safety without garbage collection, and reference counting is optional. (c) Wikipedia

On a default VS Code installation, when you create a new file its language mode is 'Plain Text'

You have to click there to set another mode.

Luckily, there's a setting you can tweak to change this. It is called files.defaultLanguage

Set it to the ID of the language you want. Those IDs display in parentheses after each entry on the language mode selector.

Hi Devs!

Last weekend I had been testing the newborn csvgen module and was looking for a CSV file to test - thus I came across an interesting datafile on Data.World with Game of Throne episodes statistics. Death statistics. These folks documented all the murders through all the 8 seasons and noted where, who, from what clan with what weapon had killed another one.

So I imported it and made an IRIS Analytics dashboard.

You Know Nothing, Jon Snow | You Know Nothing, Jon Snow | Know ...

Don't worry, Jon, with this dashboard we can figure out something ). See the details below.

Hi developers!

Suppose you have a Github repository with ObjectScript classes but without a Docker environment.

Recently I published a repository with a set of files that form a universal Docker and VSCode environment to let you either import and run your repository in InterSystems IRIS Community Edition on Docker or turn your repository into Docker and VSCode environment for InterSystems IRIS Community Edition.

So in one sentence:

Unpack these files in your folder and you have the Docker and VSCode environment for your InterSystems IRIS ObjectScript application!

See the details below.

I was searching for the most simple way to connect from visual studio code to my local instance via terminal without having to change any window.

I know this can also be achieved via telnet but seems a bit overhead if you're in your local machine.

For me the simplest sollution is to open a terminal window in VS Code, navigate to the /bin folder of your instance installation and run .\csession.exe INSTANCENAME

For simplicity you can just include your /bin folder in your path so you don't even need to navigate there

Hi Developers!

Often I find questions on how to install IRIS, connect to IRIS from IDE, setup the environment, compile, debug, maintain the repository.

Here below possibly the shortest way to set up all the environment and start development with ObjectScript on InterSystems IRIS.

Prerequisites

Make sure you have Git, Docker, and VSCode installed

Install Docker and ObjectScript extensions into VSCode

Sign in or Create an account on Github

Here we go!

I am just recently announced my project isc-tar. But sometimes it is not less interesting what’s behind the scene: how it was built, how it works and what happens around the project. Here is the story:

  • How to develop this project
  • How to test it
  • How to release new versions for publishing
  • And finally how to automate all above
  • Continuous integration

So, I would like to tell all about it.

Headache-free stored objects: a simple example of working with InterSystems Caché objects in ObjectScript and Python

Neuschwanstein Castle

Tabular data storages based on what is formally known as the relational data model will be celebrating their 50th anniversary in June 2020. Here is an official document – that very famous article. Many thanks for it to Doctor Edgar Frank Codd. By the way, the relational data model is on the list of the most important global innovations of the past 100 years published by Forbes.

On the other hand, oddly enough, Codd viewed relational databases and SQL as a distorted implementation of his theory. For general guidance, he created 12 rules that any relational database management system must comply with (there are actually 13 rules). Honestly speaking, there is zero DBMS's on the market that observes at least Rule 0. Therefore, no one can call their DBMS 100% relational :) If you know any exceptions, please let me know.
