Enhance Language Server APIs to Support Workspace-Level Projects

[madushajg]

Current Limitation

When working in a multi-package workspace, public constructs such as types, functions, and module-level variables defined in one package are not visible in other packages via the helper pane. As a result:

• Users cannot reference constructs from one project/package in another using the BI helper.
• There is no explicit mechanism to declare constructs as public so they can be consumed by other workspace packages.

This significantly limits reusability and collaboration within workspace-based projects.

Current Limitations

1. Expression Editor Scope

• The following APIs only resolve constructs within the current package and are not workspace-aware:
  • expressionEditor/types
  • expressionEditor/completion
• Workspace-level public constructs are not returned, even when they should be accessible.

2. Construct Visibility via Node Template Definition

• When defining types, functions, variables, etc there is no way to explicitly mark them as public for cross-package access.

Suggested Improvement

1. Make Expression Editor APIs Workspace-Aware

Enhance the following APIs to return workspace-level public constructs, not just package-local ones:

• expressionEditor/types
• expressionEditor/completion

These APIs should:

• Discover and include public constructs from all packages within the workspace.
• Include the addional text edit for the import statement

2. Introduce Public Access Modifiers for Constructs

Update flowDesignService/getNodeTemplate to enable users to explicitly declare constructs as public so they can be consumed by other workspace packages.

This should apply to:

• Types
• Data Mappers
• Functions
• Module-level variables (Configurables etc)

Update:

The following have been completed, and the changes have been made to the PR: ballerina-platform/ballerina-language-server#695

• Search functions throughout the workspace
• Update getNodeTemplate to support public qualifier
• Add support to search workspace-level types
• Add support for workspace-level data-mappers

Currently working on tiny changes after discussing with the frontend team.
