Overview

This PR adopts the new "advanced settings" feature from VS Code (microsoft/vscode#270142) by converting 176 internal settings to public advanced settings. These settings were previously hidden and not registered in package.json, making them inaccessible through the Settings UI. They are now properly registered with the "advanced": true tag, allowing power users to discover and configure them while keeping the default Settings UI clean for regular users.

Changes

package.json

  • Added a new "Advanced" configuration section containing 176 settings
  • All settings are tagged with "advanced": true to hide them by default in the Settings UI
  • Includes settings from:
    • ConfigKey.Internal namespace (174 settings)
    • ConfigKey.Shared namespace (2 settings: overrideProxyUrl, overrideCapiUrl)
  • Fixed default values for 14 settings that referenced constants from xtabPromptOptions.DEFAULT_OPTIONS and ResponseProcessor.DEFAULT_DIFF_PARAMS

configurationService.ts

  • Removed INTERNAL and INTERNAL_RESTRICTED options from all setting definitions
  • Removed unused INTERNAL and INTERNAL_RESTRICTED constant definitions
  • Settings are now public and properly registered in package.json

Settings Breakdown

  • Total: 176 settings
  • By Type:
    • Boolean: 110
    • String: 28
    • Number: 28
    • Object: 2
    • Array: 6
  • By Previous Restriction:
    • INTERNAL_RESTRICTED: 75
    • INTERNAL only: 101

Categories Covered

The advanced settings include configuration for:

  • Debug overrides (chat engine, token limits, proxy URLs)
  • Inline edits and completions (xtab provider, cache settings, debouncing)
  • Workspace features (code search, embeddings, indexing)
  • Project labels and metadata
  • Notebook formatting and summaries
  • Agent behavior (temperature, history summarization)
  • Experimental features and A/B tests

Impact

With VS Code's advanced settings support, these settings will:

  • Remain hidden by default in the Settings UI to avoid overwhelming users
  • Become discoverable when users enable "View advanced settings"
  • Allow power users and internal developers to access experimental and debugging features
  • Maintain backward compatibility for existing users who may have configured these settings

Testing

✅ Build: Compilation successful with 0 errors
✅ Unit tests: All passing
✅ JSON validation: package.json is valid
✅ Type matching: Default values match between TypeScript definitions and package.json

Closes #[issue_number]

<issue_title>Tag internal settings as advanced</issue_title>
<issue_description>In copilot chat we have quite number of internal/advanced settings that aren't exposed to the user in the Settings UI. With microsoft/vscode#270142 - there is a support for Advanced settings. Please adopt to this feature for these settings.

Go through all these internal settings and register them as a public setting and tag them as advanced

@Copilot @hediet
Add advanced settings to package.json and remove INTERNAL flags
382cbf8 
- Added 176 advanced settings to package.json under new "Advanced" configuration section
- All settings tagged with "advanced": true to hide them by default in Settings UI
- Removed INTERNAL and INTERNAL_RESTRICTED options from all Internal namespace settings
- Removed INTERNAL_RESTRICTED from Shared namespace settings (overrideProxyUrl, overrideCapiUrl)
- Removed unused INTERNAL and INTERNAL_RESTRICTED constant definitions
- Build and compilation successful with 0 errors

- Corrected defaults for xtabProvider settings to match DEFAULT_OPTIONS values
- Fixed nNonSignificantLinesToConverge from 4 to 3 (should use nLinesToConverge)
- All defaults now match their TypeScript definitions
