# BincioActivity — Cheatsheet

## Daily workflow

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

# 2. Rebuild the site
cd site && npm run build

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

---

## Extract

```bash
bincio extract                            # full run using extract_config.yaml
bincio extract --since 2025-01-01        # only files newer than date
bincio extract --file ride.gpx           # single file → JSON on stdout
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 && bincio extract`

---

## Site

```bash
cd site

# Symlink data (do once)
ln -sf ~/bincio_data public/data

# Dev server with hot reload
npm run dev                              # → http://localhost:4321

# Production build
npm run build                            # → site/dist/

# Preview production build locally
npm run preview
```

---

## Python / tests

```bash
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

```yaml
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)

When re-running extract isn't practical, patch the JSON directly:

```bash
# 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

```bash
# 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')
"
```
