asv-tachyon

Modern web UI for airspeed velocity results.

ASV’s built-in site is still jQuery + Flot + Bootstrap 3. asv-tachyon is a drop-in shell over the same static data that asv publish already writes (index.json, graphs/**, regressions.json). No server-side app, no new result format, no second benchmark type.

Install

pip install asv-tachyon
# or from git after building the UI once

The wheel embeds a prebuilt SPA (web/dist). From a checkout:

cd web && npm install && npm run build && cd ..
pip install -e .

Usage

asv run
asv publish
asv-tachyon serve .asv/html --open

Or replace the legacy index.html in place (keeps all graph JSON):

asv publish
asv-tachyon install .asv/html
# then any static host, or:
asv-tachyon serve .asv/html

What you get

• Overview tiles with sparklines, Explore for full charts + source
• Pairwise Compare (spyglass-style Before/After/Ratio, env or revision)
• Inventory view: SBOM-style env lock diffs (added / removed / version-bumped)
  • over published param surfaces (index.json + machines), or
  • by dropping two raw ASV result JSON files (same classify as asv-spyglass env-diff)
• Light/dark themes, machine / branch / python filters
• Same data contract as the stock ASV site — works with existing published trees

Development

# terminal 1: static data
asv-tachyon serve fixtures/sample_site -p 8765

# terminal 2: vite (optional hot reload; proxy configured to :8765)
cd web && npm install && npm run dev
