This extension provides support for the Slice Interface Definition Language (IDL).

• Syntax Highlighting
• Syntax Validation
• Error Detection & Reporting
• Go to Definition

This extension supports syntax highlighting and validation for the following Slice file types:

• .ice files, which use the original Slice syntax
• .slice files, which use the latest Slice syntax

Error checking is triggered every time a Slice file is saved or opened, and is only available for .slice files.

The Slice language server that ships with this extension can be configured with the following settings:

• slice.languageServer.enabled: A boolean indicating whether the server should be enabled. Defaults to true.

• slice.configurations: An array of configuration sets (independent groups of Slice files). This allows multiple Slice projects to exist within a single repository. Each configuration set supports the following settings:

  • paths: An array of paths to specify which Slice files should be included in this set. This field is required.

  • addWellKnownTypes: A boolean indicating whether to include the Slice definitions contained in the IceRPC Slice repository. These types are commonly used in applications utilizing Slice. Defaults to true.

If you do not specify any configuration sets, the extension will default to using the project's root directory for paths.

Note: the language server only works with .slice files, and ignores any .ice files in your project. The above settings are only meaningful for projects using .slice files.

Below is an example settings.json file which configures 2 separate Slice projects:

{
    "slice.languageServer.enabled": true,
    "slice.configurations": [
        {
            "paths": [
                "path/to/slice/directory"
            ]
        },
        {
            "addWellKnownTypes": false,
            "paths": [
                "path/to/specific/file.slice",
                "/absolute/path/to/other/slice/directory",
            ]
        }
    ]
}
