README

pix-grep

Pi tool — pattern search in files with FFF acceleration.

What it does

Replaces Pi's default grep tool with an enhanced version backed by pix-pretty.

  • FFF lifecycle — owns the frecency-ranked, SIMD-accelerated file index: inits on session_start, tears down on session_shutdown.
  • Constrained searches (path/glob set) skip FFF and use the SDK's ripgrep directly, avoiding a known FFF 0.5.2 abort on Unicode filenames. Falls back to plain ripgrep if @ff-labs/fff-node isn't installed.
  • Rendering — match-count header, highlighted pattern, file paths + line numbers, dim inline preview. Call labels show pattern, path, glob.
  • Pagination — when more matches exist than returned, the result carries a cursor id and a Use cursor="…" to continue notice.

Auto-collapse

After a configurable delay (default 10 seconds), completed output collapses to a row such as ✓ grep tickCollapse · 12 matches. Structured failures use a compact ✗ row after the delay. Expanding restores the existing bounded match preview or exact diagnostic without restarting the elapsed timer. This is controlled via the collapse section of ~/.pi/agent/pix.json:

{
  "collapse": {
    "enabled": true,
    "delaySec": 10,
    "tools": { "grep": true }
  }
}

Set collapse.tools.grep: false to disable for this tool only. See @xynogen/pix-runtime/collapse for the full API.
