The Snippets plugin's user-defined snippets are not available in Kotlin files, despite the reporter confirming the behavior with a device model and video. The editor startup path calls SnippetHandler.loadUserSnippets(), but that handler currently loads only the java and xml snippet directories. Kotlin completion already looks up snippets under the kt language key and exposes top-level, member, local, and global scopes, leaving the missing Kotlin load as the bounded gap. This plan covers Kotlin user snippets only and does not change the public plugin API or snippet format.

Summary

Extend SnippetHandler.loadUserSnippets() to load the kt directory using the existing KotlinSnippetScope.entries, matching KotlinSnippetRepository's language key and scope filenames. Keep the existing generic loader and BaseEditorActivity startup call unchanged so Kotlin follows the same clear-load-register lifecycle as Java and XML without adding a new abstraction. Add an app-module regression test that writes a representative Kotlin user snippet, invokes the production handler, and verifies the snippet is retrievable from SnippetRegistry for its Kotlin scope.

Test plan

  • A valid snippet in snippets/kt/snippets.local.json is loaded by SnippetHandler.loadUserSnippets() and returned from SnippetRegistry.getSnippets("kt", "local") with its prefix, description, and body intact.
  • Kotlin snippets in another supported scope such as global are registered under that scope and do not appear in an unrelated scope.
  • With no Kotlin snippet directory or scope file, loading completes without error and leaves the corresponding Kotlin registry scope empty; existing Java and XML loading behavior remains unchanged.

Fixes #1639

Review Change Stack

📝 Walkthrough
  • Load user-defined Kotlin snippets from the kt directory through KotlinSnippetScope.entries.
  • Preserve existing Java and XML snippet loading behavior.
  • Add regression tests for Kotlin loading, scope registration, missing directories, and registry cleanup.
  • No public API or snippet format changes.
  • Risk: Existing Kotlin snippet files may expose parsing or scope issues not covered by the regression tests.

Walkthrough

SnippetHandler now loads Kotlin user snippets. New tests verify Kotlin snippet content, scope registration, and behavior when the snippets directory is absent.

Changes

Kotlin snippet support

Layer / File(s) Summary
Kotlin snippet loading
app/src/main/java/com/itsaky/androidide/handlers/SnippetHandler.kt
SnippetHandler loads user snippets for the kt language using KotlinSnippetScope.entries.
Kotlin snippet validation
app/src/test/java/com/itsaky/androidide/handlers/SnippetHandlerTest.kt
Tests isolate the snippets directory and verify snippet content, local and global scope registration, and empty scopes when no directory exists.

Merge Risk: 🔵 Low · up to e05fa

The Kotlin snippet loading change is localized and mergeable, but the regression-test helper should use the project’s JSON serializer so snippets containing special characters are validated accurately.

Poem

A rabbit found Kotlin snippets bright,
And loaded their scopes just right.
Local and global now align,
Their bodies keep each ordered line.
No folder? Empty fields remain—
The bunny hops through tests again.

Serialize the test snippet with a JSON encoder.

writeKotlinSnippet escapes only double quotes in body. It does not escape prefix or description. A field with a backslash or control character can create invalid JSON or change the loaded content. Use the project JSON serializer to encode the complete snippet object.
