The ghcr pulls chart used a symlog y axis with a hardcoded tick list, both
copied from github-repo-stats, which builds the rest of the report. Those
settings suit views and clones - small, spiky, frequently zero - but not
container pulls, which sit in a tight band far above zero.
Consequences on the published report: the series (7,946 to 16,160) lives
entirely inside the top decade of the log scale, so a 2x swing rendered as a
14px wobble on a 200px chart and read as a flat line. Of the nine fixed ticks,
six were squashed against the baseline and 50000 fell outside the domain and
never drew, leaving a single usable gridline.
Switch to a linear scale, drop the fixed ticks so Vega derives them from the
actual domain, and format labels with SI prefixes (5k / 10k / 15k). The zero
baseline and the 10% headroom are unchanged, so the axis stays honest; the same
swing now spans 92px and the growth from ~9k to ~15k pulls/day is legible.
GHCR exposes total + 30-day daily-pull counts only in the package page
HTML (no REST or GraphQL endpoint). jgehrcke/github-repo-stats has no
notion of container metrics, so post-process the report after it runs.
New: .github/scripts/ghcr_inject.py
- Scrapes Total downloads (exact integer from title="N", not the K-rounded
display) and the 30-day sparkline (rect data-merge-count, data-date).
- Merges per-day rows into maziggy/bambuddy/ghcr-pulls.csv on gh-pages.
Fresh window overwrites overlapping dates, so GitHub's late revisions
to the last 30 days self-correct; days older than 30 stay frozen at
whatever was captured while still in-window.
- Patches latest-report/report.html: adds a TOC entry, a Container
pulls (ghcr.io) section at the top, and a Vega-Lite line+point chart
whose theme/config is cloned from the existing Total clones chart so
it inherits the report's look-and-feel.
- Bracketed by HTML-comment markers so re-runs replace rather than
stack (jgehrcke regenerates report.html every tick; we re-inject).
- Hard-fails if either scrape pattern stops matching — silent fallbacks
would let the chart freeze without notice.
Workflow: after run-ghrs, checkout source + gh-pages, run the injector,
commit only if the diff is non-empty. Uses the existing contents: write
permission; no new secrets.
