#Terminal

Posts that relate to discussions on utilizing the Terminal tool.

If anyone has experience debugging Embedded Python or has insight into why an ObjectScript method when called from a Python method would not work but would work when called directly via ObjectScript or in a Python shell, your help would be appreciated!

We have an ObjectScript ClassMethod called GetTemplateString() which takes in a templateName of String type and uses the template name to get the template object, access the Code, and read the code into a templateString. The string version of the Code is returned.

Hi

I have a question about terminal, when I run a class from it that contains an error I get a report of error as I would expect, and then an apparently random three letter code is appended to the namespace name in the prompt, as shown below.

GMMHTIE>do ##class(temp.Nothing).What()

w !, tParisAnswer
^
<UNDEFINED>zWhat+23^temp.Nothing.1 *tParisAnswer
GMMHTIE 2d1>

Then, when I try to enter a command I get an error

Hello everyone,

I have an issue related to Visual Studio Code and its InterSystems extension when exporting routines from the database to the file system.

The code entered via the terminal editor is encoded in DOS code page 437, but when I export it to my file system, even if I set the file opening to DOS CP 437, the accented characters which are two bytes long cause problems.

Hello everybody,

I've been experimenting with Embedded Python and have been following the steps outlined in this documentation: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

I'm trying to convert a python dictionary into an objectscript array but there is an issue with the 'arrayref' function, that is not working as in the linked example.

This is a snapshoot of my IRIS terminal:

Hi,

I have an odd problem that occurs when I'm trying to import lookup tables in the XML format into Studio.

I store my files in in C:\CodeRepository.

I can manually import these lookup tables using "Import local..." option in the InterSystems Studio.

However, when I'm trying to import them using command in terminal: do $system.OBJ.LoadDir("C:\CodeRepository\","ck")

I'm getting the following error:

Interacting with Users in the Terminal: A Guide to Using %Library.Prompt in IRIS

Have you ever wondered how commands like ^DATABASE engage users in the terminal? Or perhaps you're writing an automation routine and want ways to specify options directly from the terminal. Thankfully, the %Library.Prompt class in IRIS offers a straightforward way to do so!

Hey Community,

Watch this video to learn how to use terminal aliases for InterSystems IRIS and also how to set it up with your Docker Developer Environment:

Hi Devs!

Recently I was impressed by @Dan Pasco's article where he shares also how he uses terminal aliases.

Terminal aliases is a very powerful tool for developers and sys admins if you often need to call some cumbersome terminal expressions and make it shorter and cleaner. Here is the documentation.
Yes!

But what about Docker environments? What if you are fan of Docker dev environments but also want to keep using your favorite aliases with Docker as well?

Turned out it is very possible.

I'm wondering what the best practice is for handling %Status values within the terminal. 
1. set tSC=...
    do $SYSTEM.Status.DisplayError(tSC)
 
2. set tSC=...
   zwrite tSC

3. An alternative?

Is there a meaningful difference between the two? Should one be used over the other for any reason? Should something else be used?

I just realized that operating system command execution does not work on Windows console if the IRIS service is started using a different user than Local System account (the default).

I always change the user configured in the IRIS service and I believe this is a standard good practice, particularly in "real" environments (be it production, stage, test or development) that are part of Windows Active Directory Domain.

Have you ever been editing files in VS Code, but needed to check a global value or run a few ObjectScript commands? Now you can, with no setup required! If you have vscode-objectscript extension version 2.10.0 or later and are connected to InterSystems IRIS 2023.2 or later, you can now open a terminal connection to your server, regardless of where it's located.

There are three ways to open this new terminal:

k9s - Manage Your IrisClusters In Style

K9s is a terminal-based UI (aka kubectl clown suit), to manage Kubernetes clusters that drastically simplifies navigating, observing, and managing your applications in K8s, including Custom Resources like the InterSystems Kubernetes Operator (IKO) and ArgoCD Applications. If you are about to take your CKD, CKA, or CKS, leave k9s well enough alone for awhile as the abstraction to kubectl will become the standard for navigating the cluster and you will undoubtedly become estranged to the extended flags of kubectl and bomb the exam.

Hi everyone,

I'm attempting to compile a basic Python code on a remote server, but it appears that the compiler doesn't recognize the language.

The remote server is running a virtual machine with Oracle Linux Server 7.9 (64-bit), and it has IRIS for UNIX (Red Hat Enterprise Linux for x86-64) 2021.1 (Build 215U) [HealthConnect:3.3.0] installed.

When I try to compile a script that includes a Python ClassMethod, such as this "testpy.cls":

Hello Everyone,

We currently have CSP application that runs under 2 servers(usually primary), and every month the server reboots for patching SERVER1(primary) in the morning and SERVER2(backup) at night.

Whenever the SERVER1 reboots SERVER2 behaves as primary and when SERVER1 comes back up it will act as backup server.

First Patching:

So, when SERVER1 is down, I need to start httpd service for SERVER2 and stop httpd service for SERVER1 (which is now backup server).

For my Embedded Python ONLY demo package I need some user input.
Similar to ObjectScript

read "say somthing",reply

I use the Python equivalent

reply = input("say something")

And this works excellent without problems from Terminal or Doker console

BAD SURPRISE:
with WebTermnial ObjectSscript works fine, but embedded Python fails badly.

Hello,

I have set up a Docker image with IrisHealth Community Edition and created a backup of all databases with the Management Portal. Obviously, the restore requires a different way, i.e. a terminal or session needs to be started to use a "Do ^DBREST".

Due to the manual first a session (which is probably same as iristerm terminal) needs to be started:

docker exec -it iris iris session iris

If I enter "DO ^DBREST", I get the answer:

<NOROUTINE> *DBREST.

Hi there,

I want to use regex in my code, and I saw that the %Regex.Matcher class contains a property "OperationLimit" that you can also set to a number of steps that the regex engine should take maximum in analysing a given string. So far so good.

I tried to set the property with the function OperationLimitSet() to a silly value like 3. In 3 steps only very few regex should be executed, right? But what I found is that my regex always comes up with a solution. Here is what I did:

First I initialised my %Regex.Matcher.

Visual Studio Code, like Atelier, connects to IRIS through the Web Server and a web service, unlike Studio that connect to the SuperServer port.

What about the VS Code terminal? Does that open a shell with SSH or does it also use a web service?

In other words, does an IRIS developer using VS Code need direct access to the IRIS instance with SSH or the SuperServer port, in addition to the external or private web server to execute terminal commands?

Is that different with linux vs. Windows?

Hi Developers!

There is a recent update came for developer community images of InterSystems IRIS and IRIS For Health.

This release comes with Environment variables support.

Currently 3 variables are supported:

  • IRIS_USERNAME=user to create
  • IRIS_PASSWORD=with password
  • IRIS_NAMESPACE=create namespace if doesn't exist

Here is what you can do - see below.

Start iris with your username and password created:

docker run --rm --name iris-sql -d -p 9091:1972 -p 9092:52773  -e IRIS_PASSWORD=demo -e IRIS_USERNAME=demo intersystemsdc/iris-community

Hi Devs!

For me, one of the most painful things about ObjectScript is ##class(Class).Method() typing to call a class method in code or in a terminal. I even submitted an idea to simplify it in ObjectScript.

But! There is a new feature in VSCode ObjectScript that was just introduced to the plugin - Copy Invocation!
