Walkthrough

The pull request updates the SlashCommandApi in src/index.ts by modifying the addCommand callback signature to return string | null | void instead of void. A new slashCallback function was introduced to handle slash command invocations, which resolves the target block UID from context or active textarea and computes an insertAt position before opening the Giphy picker. The previous inline callback logic has been replaced with this new pattern. Error handling via try/catch was added around slashCommand.addCommand registration, and legacy helper functions were removed as part of the refactor.

src/index.ts (1)

35-36: window.roamAlphaAPI accessed without null safety.

Line 35 accesses window.roamAlphaAPI.ui.getFocusedBlock() directly, while slashCommand on lines 58–62 is accessed with optional chaining. If the slash callback ever fires in a context where roamAlphaAPI is unavailable, this will throw. Consider guarding with optional chaining for consistency:

Suggested diff

-    const focusedUid = window.roamAlphaAPI.ui.getFocusedBlock()?.["block-uid"] || "";
+    const focusedUid = window.roamAlphaAPI?.ui?.getFocusedBlock()?.["block-uid"] || "";
