Here is a programmatic solution to list all defined namespaces and their databases using both ObjectScript and Python:

ObjectScript Code

ClassMethod ListNamespacesAndDatabases()
{
    // List all defined namespaces
    Set namespaces = ##class(%SYS.Namespace).ListAll(.result)
    zwrite result

    // For each namespace, get its associated databases
    For i = 1:1:result.Count() {
        Set nsName = result.GetAt(i)
        Write "Namespace: ", nsName, !
        Set dbs = ##class(%SYS.Namespace).Databases(nsName, .dbInfo)
        zwrite dbInfo
    }
}

This code lists namespaces and retrieves their database configurations using the appropriate methods provided by the %SYS.Namespace class [1][2].

Python Code

To do this in Python, you need to work within the context of an InterSystems IRIS Python environment.

import iris

def list_namespaces_and_databases():
    result = []
    # List all namespaces
    namespaces = iris.cls('%SYS.Namespace').ListAll()
    for ns in namespaces:
        databases = iris.cls('%SYS.Namespace').Databases(ns)
        db_info = {key: value for key, value in databases.items()}
        result.append({'namespace': ns, 'databases': db_info})

    return result

# Usage
namespaces_and_databases = list_namespaces_and_databases()
for item in namespaces_and_databases:
    print(f"Namespace: {item['namespace']}")
    for db, info in item['databases'].items():
        print(f" Database: {db}, Info: {info}")

This Python example uses the iris module to interact with the InterSystems IRIS system. It retrieves both the namespaces and their associated databases using the same functionalities as ObjectScript [1][3].

These code snippets allow you to programmatically list namespaces and their databases from InterSystems IRIS. Let me know if you need further clarification or assistance!

You may encounter the error Failed to save 'Utils.cls': Unable to write file 'isfs://mip:mz/API/Utils.cls?project=MZ' (Unknown (FileSystemError): Unknown Error) when trying to save or compile a class in Visual Studio Code due to several potential reasons.

Here are some troubleshooting steps based on relevant information:

1. Do Not Alter First Line of New Files: If you are creating a new file in the Explorer tree in VS Code and modify or delete the first automatically generated line after naming the file (e.g., foo.cls), it may cause issues saving the file. Always start coding on the second line and retain the first untouched [1].

2. Namespace and Server Connection Issues: Ensure your connection to the server is functional:

   • Check if you have configured the namespace and server connection properly in VS Code.
   • Use PuTTY or the browser-based management portal to verify connectivity to the server and test your file import or routine executions, as they should work without errors if connectivity is valid [1].

3. Correct Permissions: Make sure that the user configured for your VS Code ObjectScript plugin has the necessary privileges to write to the namespace or specific filesystems in InterSystems IRIS.

4. VS Code Plugin Setup: Ensure the required InterSystems ObjectScript extensions, such as the ObjectScript Extension Pack and Server Manager, are installed and properly configured [1].

If this doesn't resolve the problem, it may be useful to look at the server logs or other error details in the Audit Trail (%SYS.Audit) to get more information.
