Known Vulnerabilities Visual Studio Marketplace Version

InterSystems ObjectScript extension for VS Code

InterSystems® ObjectScript language support for Visual Studio Code, from the InterSystems Developer Community.

Features

  • InterSystems ObjectScript code highlighting support.

    example

  • Debugging ObjectScript code.

  • Intellisense support for commands, system functions, and class members.

  • Export of existing server sources into a working folder:

    • open Command Palette (F1 or /Ctrl+Shift+P)
    • start typing 'ObjectScript'
    • choose ObjectScript: Export Sources
    • press Enter
  • Save and compile a class:

    • press /Ctrl+F7
    • or, select ObjectScript: Import and Compile Current File from Command Palette
  • Direct access to edit or view server code in the VS Code Explorer via isfs and isfs-readonly FileSystemProviders (e.g. using a multi-root workspace). Server-side source control is respected.

  • Server Explorer view (ObjectScript: Explorer) with ability to export items to your working folder.

Installation

Install Visual Studio Code first.

Open VS Code. Go to Extensions view (/Ctrl+Shift+X), search for "vscode-objectscript" and install it. Or install direct from the ObjectScript extension page on Visual Studio Marketplace.

Enable Proposed APIs

This extension is able to to take advantage of some VS Code APIs that have not yet been finalized.

The additional features (and the APIs used) are:

  • Server-side searching across files being accessed using isfs (TextSearchProvider)
  • Quick Open of isfs files (FileSearchProvider).
  • Improved labels (tabs, file lists, tooltips) for server-side files (ResourceLabelFormatter)

To unlock these features (optional):

  1. Download and install a beta version from GitHub. This is necessary because Marketplace does not allow publication of extensions that use proposed APIs.

    • Go to https://github.com/intersystems-community/vscode-objectscript/releases
    • Locate the beta immediately above the release you installed from Marketplace. For instance, if you installed 1.0.6, look for 1.0.7-beta.1. This will be functionally identical to the Marketplace version apart from being able to use proposed APIs.
    • Download the VSIX file (for example vscode-objectscript-1.0.7-beta.1.vsix) and install it. One way to install a VSIX is to drag it from your download folder and drop it onto the list of extensions in the Extensions view of VS Code.
  2. From Command Palette choose Preferences: Configure Runtime Arguments.

  3. In the argv.json file that opens, add this line:

"enable-proposed-api": ["intersystems-community.vscode-objectscript"]
  1. Exit VS Code and relaunch it.
  2. Verify that the ObjectScript channel of the Output panel reports this:
intersystems-community.vscode-objectscript version X.Y.Z-beta.1 activating with proposed APIs available.

After a subsequent update of the extension from Marketplace you will only have to download and install the new vscode-objectscript-X.Y.Z-beta.1 VSIX. None of the other steps above are needed again.

Configure a Connection

To be able to use many features you first need to configure the connection to your IRIS/Caché/Ensemble server(s) in your VS Code settings. If you are unfamiliar with how settings work and how they are edited, use that link.

We recommend you define server connections in the intersystems.servers object whose structure is defined by the InterSystems Server Manager helper extension.

Install that extension and consult its documentation about commands for easy setup of connections, plus assistance when editing the JSON definition directly.

For more tips about the intersystems.servers object, see the Notes section below.

Client-side Editing

A simple workspace -- a local working folder in which you edit InterSystems source files and manage them using client-side source control (e.g. Git) -- will use the objectscript.conn settings object to import locally-edited code into a namespace on a server, compile it there and run/debug it, and also for initial export of an existing codebase (optional). This settings object is usually defined in Workspace Settings, for example in the .vscode/settings.json file of your working folder.

A quick way to add objectscript.conn to a new working folder is:

  1. Open the folder in VS Code.
  2. Use the InterSystems icon on the activity bar to switch to ObjectScript Explorer view.
  3. Click the 'Choose Server and Namespace' button.
  4. Respond to the sequence of quickpicks. You can also define a new server at the start of this sequence by using the '+' button.

For more about objectscript.conn see the Notes section below.

Server-side Editing

To edit code directly in one or more namespaces on one or more servers (local or remote) we recommend creating a workspace definition file (for example XYZ.code-workspace) where you specify one or more root folders that directly access namespaces via the isfs or isfs-readonly URI schemes. The only difference between these two schemes is that any file opened from a folder using the isfs-readonly scheme will be set as read-only in VS Code and thus protected against being changed.

  1. Start VS Code.
  2. If your last-used folder opens, use 'Close Folder' on the 'File' menu ('Code' menu on macOS). Or if what opened was your last-used workspace, use 'Close Workspace'.
  3. On VS Code's Explorer view (/Ctrl+Shift+E), click the 'Choose Server and Namespace' button. Respond to the sequence of quickpicks. You can also define a new server connection during this process.
  4. Use 'Save Workspace As...' to store your workspace definition in a file with a .code-workspace extension.

For more about isfs and isfs-readonly folder specifications see the Notes section below.

Notes

  • Connection-related output appears in the "Output" view while switched to the "ObjectScript" channel using the drop-down menu on the view titlebar.

  • For Caché/IRIS instance with maximum security level, add %Development role for /api/atelier/ web-application (read more).

  • If you are getting ERROR # 5540: SQLCODE: -99 Message: User xxx is not privileged for the operation when you try to get or refresh class/routine/include- lists, grant your username (or a SQL role you hold) execute permission for the following SQL Procedure in the target namespace.

GRANT EXECUTE ON %Library.RoutineMgr_StudioOpenDialog TO xxx

More about intersystems.servers

This settings object is useful for both client-side and server-side development.

  • An example server definition named 'local':
  "intersystems.servers": {
    "local": {
      "webServer": {
        "scheme": "http",
        "host": "127.0.0.1",
        "port": 52773
      },
      "description": "My local IRIS",
      "username": "me"
    }
  }
  • By defining connections in your User Settings they become available for use by any workspace you open in VS Code. Alternatively, define them in workspace-specific settings.

  • Setting the username property is optional. If omitted it will be prompted for when connecting, then cached for the session.

  • Setting a plaintext value for the password property is not recommended. Instead, run the InterSystems Server Manager: Store Password in Keychain command from Command Palette.

  • If no password has been set or stored it will be prompted for when connecting, then cached for the session.

More about objectscript.conn

This settings object is primarily relevant when doing client-side development.

  • We recommend that objectscript.conn uses its server property to point to an entry in intersystems.servers. For example:
  "objectscript.conn": {
    "active": true,
    "server": "local",
    "ns": "USER"
  }
  • The mandatory ns property defines which server namespace you will work with.

  • When the server property is set, any username or password properties of objectscript.conn are ignored. Instead these values come from the intersystems.servers entry.

More about isfs and isfs-readonly workspace folders

Server-side development is best done using isfs folders. The read-only variant isfs-readonly is also useful when doing client-side development, since it enables server-side searching of your codebase.

To modify how your folder behaves, edit the JSON of your workspace definition (XYZ.code-workspace file). Get there by running the 'Preferences: Open Workspace Settings (JSON)' command. Edit your uri property.

  • The csp query parameter indicates web application files are to be shown. The uri path optionally specifies which application. The ns parameter must specify the same namespace the application is configured to use. In the following example the first folder is for the /csp/user web application in the USER namespace of the server named 'local' and the second gives read-only access to all web applications that reside in the %SYS namespace. The second folder also uses the optional name property:
    {
      "uri": "isfs://local/csp/user?ns=USER&csp"
    },
    {
			"name": "local:%SYS web files (read-only)",
      "uri": "isfs-readonly://local/?ns=%SYS&csp"
    }
  • To see only classes in the Xxx.Yyy package, format the uri like this:
    {
      "uri": "isfs://local/Xxx/Yyy?ns=USER&type=cls"
    }
  • Other query parameters that can be specified include:
    • type=cls to show only classes, or type=rtn to show only routines.
    • flat=1 to flatten the hierarchy.
    • generated=1 to show generated items.
    • filter=filterspec to use a filter specification formatted in the same way as used in InterSystems Studio's File Open dialog (e.g. filter=Ensem*.inc).
