BincioActivity — Cheatsheet

Daily workflow

# 1. Drop new .fit / .gpx / .tcx files into your input dir, then:
uv run bincio extract

# 2. Rebuild the site (merges any sidecar edits, then builds)
uv run bincio render

# 3. Done — copy site/dist/ to your host

---

Extract

uv run bincio extract                            # full run using extract_config.yaml
uv run bincio extract --since 2025-01-01        # only files newer than date
uv run bincio extract --file ride.gpx           # single file → JSON on stdout
uv run bincio extract --input ~/rides \
                      --output ~/bincio_data    # override config paths

Re-extraction is safe — unchanged files are skipped (hash-based dedup). To force a full re-extract: rm -rf ~/bincio_data && uv run bincio extract

---

Render

uv run bincio render                            # merge edits + production build → site/dist/
uv run bincio render --serve                    # merge edits + dev server → http://localhost:4321
uv run bincio render --data-dir ~/bincio_data   # explicit data dir

bincio render always runs merge_all() first (applies sidecar edits, produces _merged/), then symlinks site/public/data → _merged/ and runs the Astro build or dev server.

# Direct npm (skips merge step — use for quick site-only iteration)
cd site
npm run dev
npm run build
npm run preview

Edit

# Start the edit server (port 4041 by default)
uv run bincio edit --data-dir ~/bincio_data

# Set PUBLIC_EDIT_URL=http://localhost:4041 in site/.env to enable the Edit button
# Then browse to any activity and click Edit — a drawer opens in the same page

Saves write a sidecar .md to ~/bincio_data/edits/{id}.md and immediately trigger a merge. Refresh the page to see the updated content.

Sidecar format

---
title: "Renamed title"
sport: cycling
gear: "Trek Domane"
highlight: true          # sort to top of feed
private: false           # true = hidden from feed
hide_stats: [cadence]    # suppress stat panels
---

Description in **markdown**. Images go in the gallery — drag & drop in the Edit drawer.

Python / tests

uv sync                                  # install / update deps
uv run bincio --help                     # CLI reference
uv run pytest                            # full test suite
uv run pytest tests/test_fit.py -x       # single file, stop on first fail
uv run pytest -k "sport"                 # run tests matching keyword
uv run pytest -v                         # verbose output

Data store layout

~/bincio_data/
  index.json                    ← feed index (all activities, summaries)
  activities/
    2024-05-15T08:30:00Z.json   ← full detail + 1Hz timeseries
    2024-05-15T08:30:00Z.geojson  ← simplified GPS track

Activity ID format: YYYY-MM-DDTHH:MM:SSZ (UTC, always Z suffix). IDs are stable — safe to use in bookmarks and links.

---

extract_config.yaml — key fields

owner:
  handle: yourname
  display_name: Your Name

input:
  dirs:
    - ~/Activities          # scanned recursively for GPX/FIT/TCX/.gz
  metadata_csv: ~/strava_export/activities.csv   # optional

output:
  dir: ~/bincio_data

default_privacy: public     # public | blur_start | no_gps | private
incremental: true           # false = re-process everything
track:
  rdp_epsilon: 0.0001       # GPS simplification — larger = fewer points
  timeseries_hz: 1          # samples/sec in stored JSON (1 = 1 Hz)

---

Privacy

Value	Track served	Stats	In index
public	Full GPS	✓	✓
blur_start	First/last 200 m removed	✓	✓
no_gps	None	✓	✓
private	None	✗	✗

Set per-activity in a sidecar .md file, or globally via default_privacy.

---

Sports

Canonical sport values: cycling running hiking walking swimming skiing other

Sub-sports: road mountain gravel indoor trail track nordic

FIT files: sport is read from the sport frame, with session frame as fallback. Strava CSV: Activity Type column overrides the FIT-detected sport (authoritative). Mapping lives in bincio/extract/sport.py.

Patching activities (manual fixes)

Prefer the Edit drawer for title/sport/description/photo changes — it writes a sidecar and keeps extracted data pristine. For bulk fixes or fields not exposed in the UI, patch the JSON directly:

# Fix sport for a single activity
python3 -c "
import json
p = 'site/public/data/activities/2025-03-16T113005Z.json'
d = json.load(open(p))
d['sport'] = 'skiing'
d['sub_sport'] = 'nordic'
json.dump(d, open(p,'w'), separators=(',',':'))
"

# Then update the index.json to match
python3 -c "
import json
idx = json.load(open('site/public/data/index.json'))
for a in idx['activities']:
    if a['id'] == '2025-03-16T113005Z':
        a['sport'] = 'skiing'
        a['sub_sport'] = 'nordic'
json.dump(idx, open('site/public/data/index.json','w'), separators=(',',':'))
"

Common diagnostics

# Count activities by sport in the data store
python3 -c "
import json, glob
from collections import Counter
files = glob.glob('site/public/data/activities/*.json')
c = Counter(json.load(open(f))['sport'] for f in files)
print(dict(c.most_common()))
"

# Find activities with 0 distance
python3 -c "
import json, glob
for f in glob.glob('site/public/data/activities/*.json'):
    d = json.load(open(f))
    if (d.get('distance_m') or 0) == 0 and d.get('sport') != 'other':
        print(d['id'], d['sport'], d['title'])
"

# Find activities still tagged 'other'
python3 -c "
import json
idx = json.load(open('site/public/data/index.json'))
others = [a for a in idx['activities'] if a['sport'] == 'other']
for a in others[:20]:
    print(a['started_at'][:10], a.get('source','?'), a['title'])
print(len(others), 'total')
"
