📝 Walkthrough

Walkthrough

The Pi extension now uses Pi’s built-in expansion behavior for compact ffgrep and fffind output. Custom mouse handling, expansion state, and UI invalidation were removed. Tests use the render-time expanded option.

Changes

Compact search rendering

Layer / File(s)	Summary
Shared compact renderer packages/pi-fff/src/index.ts, packages/pi-fff/test/extension.test.ts	The shared renderer now uses options.expanded. Custom MouseRegion handling and extension-managed expansion state were removed. Tests add the required TUI mock helpers.
Search tool integration and validation packages/pi-fff/src/index.ts, packages/pi-fff/test/extension.test.ts	Grep and find renderers pass expansion options to shared rendering. Multi-grep previews use a 15-line collapsed limit. Tests verify collapsed and expanded output.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix narrow-width overflow.

At Line 825, the method appends the marker and suffix even when previewWidth cannot fit the marker. For example, a width of 19 with ... (2 more lines) emits 22 columns. Return the suffix alone when the preview area is too narrow. Add a narrow-width test.

Proposed fix

       const previewWidth = availableWidth - suffixWidth - 1;
+      if (previewWidth === 0) return [this.suffix];
       if (visibleWidth(this.preview) <= previewWidth) {
         return [`${this.preview} ${this.suffix}`];
       }

       const markerWidth = visibleWidth(this.marker);
+      if (markerWidth > previewWidth) return [this.suffix];
       return [
