• Fix Autocomplete - Nothing happens with autocomplete activated #5101

Context

This PR fixes an IllegalArgumentException: argument type mismatch error that occurred when enabling autocomplete (Ghost Provider) in the JetBrains plugin. The error was triggered when the Ghost service attempted to update the status bar with autocomplete information, causing the plugin to crash and preventing users from using the autocomplete feature.

The root cause was a type mismatch in the RPC communication between the VSCode extension host and the JetBrains plugin. When the Ghost service set the status bar tooltip to a MarkdownString object (as per VSCode's API), it was serialized and sent to the JetBrains side, but the receiving method expected a simple String? type, causing the reflection-based method invocation to fail.

Implementation

The fix involved updating the type signatures in MainThreadStatusBarShape.kt to be more flexible and align with VSCode's StatusBarItem API:

Key Changes:

1. Changed tooltip parameter type from String? to Any?

   • VSCode's StatusBarItem allows setting tooltips to either strings or MarkdownString objects
   • When a MarkdownString is used, it gets serialized as a Map with properties like value, isTrusted, supportThemeIcons, supportHtml, and uris
   • The new Any? type allows the method to accept both simple strings and serialized MarkdownString objects

2. Changed accessibilityInformation parameter type from Boolean? to Any?

   • According to VSCode's API, this should be an object with label and role properties, not a Boolean
   • Changed to Any? to match the actual API contract

3. Added extractTooltipText() helper method

   • Properly extracts the text value from both String and MarkdownString (Map) tooltips
   • Handles the serialized MarkdownString format by extracting the value property from the Map

4. Created comprehensive test coverage

   • Added ReflectUtilsStatusBarTest.kt with tests for:
     • Double to Int conversion for priority values (ensuring the existing reflection logic still works)
     • Boolean accessibilityInformation handling
     • MarkdownString-like tooltip objects (simulating the actual error scenario)

How to Test

1. Enable the JetBrains plugin in your IDE (IntelliJ IDEA, PyCharm, etc.)
2. Configure a Ghost autocomplete provider:
   • Open Kilo Code settings
   • Navigate to Autocomplete settings
   • Enable autocomplete
3. Open a code file and start typing

Alternative Test (if you don't have autocomplete credits):

1. Run the new test suite:

   cd jetbrains/plugin
   pnpm test src/test/kotlin/ai/kilocode/jetbrains/util/ReflectUtilsStatusBarTest.kt

2. All tests should pass, including the new test setEntry with MarkdownString-like tooltip object test
