* feat(card): configurable start of week for heatmap + weekday cards
New -start-of-week CLI flag (and start_of_week action input) rotates the
contribution-heatmap rows and the productive-weekday bars so users whose
calendars start on Monday (or any other day) get matching output. Default
stays Sunday to preserve existing renders.
* docs: note start-of-week in design-guidelines, codebase-summary, deployment-guide
- design-guidelines: heatmap row order + productive-weekday bar order now derive from Profile.WeekStart
- codebase-summary: list new weekday_start_test.go cases + TestParseWeekday
- deployment-guide: mention start_of_week as an optional action input in the workflow template
Two cuts together keep the productive-time and productive-weekday
titles at the same 15 px the rest of the gallery uses:
1. utcOffsetLabel is now compact. Integer offsets drop the '.00'
padding ("UTC+7" vs the old "UTC+7.00") and non-integer offsets use
the colon form ("UTC+5:30", "UTC+5:45"). Saves 3 chars for the
common integer case, so "Commits by Hour (last year, UTC+7)" lands
at 34 chars — inside the 15 px budget.
2. weekdayTitle no longer embeds the UTC label. Day-of-week aggregates
by whole days; clock precision isn't informative there, and
dropping it shortens the title to 30 chars so the full 15 px lands
for every timezone.
Quarter-hour-zone users (Kathmandu UTC+5:45) see the hour title drop
to 14 px — 37 chars still exceeds the budget — but that's a rare
case and only 1 px off.
TestUTCOffsetLabel updated to the new format. TestFitTitleFontSize
pinned the new titles.
## Heatmap — two halves, 8x8 cells
The single-row 53-week layout could never hold square cells larger than
4x4 inside a 340 px card — cramped. Split the year in half (ceil(weeks/2)
on top, floor on bottom) and each half is ~27 weeks wide, freeing the
cells to be 8x8 (4x the area) while keeping comfortable left (30 px)
and right (~67 px) gutters. Grid:
topPadA = 45, half = 7*9 - 1 = 62 tall
halfGap = 13
topPadB = 120, same 62 tall
grid bottom at y = 182, 18 px frame margin
Year still reads top-to-bottom left-to-right, just with one extra line
break at the midpoint. Dropped the separate Less/More legend — at 8x8
the intensity gradient is self-explanatory, and the removal buys the
vertical space the new layout needs.
Refactored into a helper `renderHeatmapHalf` so the two halves share a
single code path (labels + month markers + cells).
## Font-size vocabulary
Four named constants in svg.go: fontBody=12, fontLabel=11, fontAxis=10,
fontBigNum=28. Every card's existing literals already sit on this
ladder except the heatmap, which was using 9 for weekday/month labels.
Heatmap now routes through fontAxis so the whole gallery shares one
size scale.
Other cards' literals weren't rewritten to reference the constants
(pure churn for no behavior change); the constants give future cards
the vocabulary and the design-guidelines the schema.
The 4x12 rectangular stretch from v1.2.3 read as "weird". Requirement
is square cells + comfortable side padding. Given the 53-week hard
constraint, those two requirements together pick the cell size:
53 * (size + gap) + leftPad + rightPad = 340
Candidates audited:
6 x 6, gap 1 → 371 wide, overflows the frame
5 x 5, gap 1 → 318 wide, only 11 px of total side padding ("very close")
5 x 5, gap 0 → 265 wide, cells touch (need a stroke to fake a gap)
4 x 4, gap 1 → 265 wide, 30 + 45 px gutters, real 1 px gaps ✓
3 x 3, gap 2 → 265 wide, cells become pinhead-sized
4 x 4 with a 1 px gap is the largest square that keeps breathing room
on both sides without any rendering trickery. Grid is 35 px tall;
there's leftover vertical space on the card but short beats "stretched
horizontal bands" visually. Bump topPad from 62 → 70 to offset the
grid slightly down from the title and reduce that apparent emptiness.
Legend swatches also revert to the same cellSize so the Less/More
bar matches the grid visually again.
Cells were 4 × 4 with 1 px gap: the grid used 35 of 140 available
vertical pixels (25 %) and ~80 px of dead space below. Widening the
cells isn't an option — 53 weeks already consume every horizontal
pixel past the weekday-label gutter. So stretch vertically instead:
cellW = 4 (unchanged) cellH = 12 cellGap = 1
Grid footprint is now 265 × 91 px inside a 340 × 200 frame, with a 32
px gap below the grid for the legend. Each weekday reads as a distinct
horizontal band instead of a cramped postage-stamp row.
Legend keeps 8 × 8 SQUARE swatches so the "Less ▢▢▢▢▢ More" row is
still recognisable as an intensity legend rather than a stretched echo
of the data cells. Label baseline offset switches from `cellSize - 1`
to `cellH - 3` so "Mon"/"Wed"/"Fri" sit visually centred in the taller
rows.
Two follow-ups:
1. "Top 7 languages" counts rows the reader sees, not "7 named + Other".
Revert collapseOther to the original semantic: when the input has more
than n entries, keep in[:n-1] named and fold the tail into a single
"Other" row — 7 rows total with topN=7. Input with ≤7 real languages
still passes through unchanged. Test and adversarial-profile updated
to pin the cap (6 named + Other, Shell/Kotlin/Java collapse).
2. Contributions heatmap grid was touching the card right edge
(leftPad 22 + 53*6 = 340 exactly). Shrink cells from 5×5 to 4×4 and
bump leftPad to 30, giving 45 px of right gutter. Grid no longer
reads as bleeding into the frame border; weekday label column also
gets a few more pixels of breathing room on the left.
With topN=7 the previous collapseOther kept only the first 6 entries
and added "Other" as the 7th row. A user expecting to see 7 actual
languages in the legend saw six named languages plus "Other" — the
exact complaint just raised about the profile repo's donut.
Flip the semantic: the "top N" slots are reserved for real languages,
and "Other" is an extra row when (and only when) there's a non-zero
tail past the Nth entry. Topologically that means up to 8 legend
rows — still fits the card frame (row 8 text baseline at y=195, card
height 200).
- TestDonutTopSevenPlusOther pins the new contract with a 9-language
input.
- adversarialProfile in TestCardsFitFrame bumped to 9 languages so
the stress test exercises the 8-row legend geometry.
- design-guidelines: the donut row re-reads "Up to 7 named languages,
plus an 'Other' row when the tail is non-zero (8 rows max)".
project-roadmap.md went from a 146-line phase-by-phase history to a
48-line focused view: what's planned, what's out of scope. Completed
work is already in git log + GitHub Releases — the doc re-telling it
was the thing most likely to rot and least likely to be read.
project-overview-pdr.md: "Open questions" section dropped its stale
bullet list and now just points at project-roadmap.md (single source of
truth for planned work).
code-standards.md: drop the ".claude/ directory" commit rule — that's
a per-user workflow detail, not a project-level standard. Docs are for
users of the CLI/Action and coworkers of this repo, nothing else.
The repo is already listed on the Marketplace as ghstats-cards, so the
multi-paragraph "open the release page, tick the checkbox, re-publish"
instruction was stale. Replace with a one-line note pointing at the
existing listing and stating that new releases inherit visibility
automatically.
Several recent code changes hadn't propagated to the docs:
- design-guidelines
* Card frame title row: document the 11–15 px auto-shrink (not a flat
15 px anymore).
* Donut Top-N: already 7 (updated earlier).
* Bar-chart section renamed to cover weekday + by-year too; document
the peak-vs-dim highlight convention and the niceTicks yMax ≥ max
invariant.
* Add Heatmap / Stat-column (streak) / List (top-starred) card
sections — they were missing entirely.
* Rewrite "Text overflow" from "we don't truncate" to the current
truth (truncate helper, formatTick abbreviations).
* Replace dangling `truncateName` reference with `truncate`.
- code-standards
* SVG output standards: call out truncate, formatTick abbreviation,
header auto-fit so the card-review gate reflects what the renderers
actually do.
- codebase-summary
* Layout tree: svg.go / axis.go comments list the helpers they now
contain; productive.go notes the weekday histogram.
* demo/ tree shows the index vs per-theme split.
* Data-flow diagram includes Weekday in the productive pass.
* Test coverage row lists TestCardsFitFrame / TestFitTitleFontSize /
TestNiceTicksCoversMax — the new invariant guards.
- system-architecture
* Shared primitives list adds renderWeekday and renderHeatmap; donut
blurb updated to "top 7".
* New "Chart-geometry invariants" block documents niceTicks ceiling,
formatTick abbreviation, header auto-fit.
- project-roadmap
* Phase 7.5 bullet updated to describe the index + per-theme demo
split (was single-README TOC).
Legend at x=20-155 fits 7 rows (y=55 to y=175); donut at cx=250, cy=110
is unaffected. Update the design-guidelines table to match. Stress test
still passes — the legend column never leaves its left-side gutter.
Three cards overflowed the 340×200 frame for realistic profile data:
- contributions-heatmap: the classic case — 53 weeks at 9px cellSize + 2px
gap pushed the grid out to x≈611. Shrink to cellSize=5, cellGap=1 so
leftPad(22) + 53*6 = 340 (exact fit). Drop month labels within 20 px of
the right edge so "Dec"/"Apr" can't stick past the frame.
- streak: the third column rendered "N / M" at font-size 28, centered at
x=282. For 4+ digit totals (e.g. 584 / 3031) the text extended to x≈347.
Refactor to show the active-days integer by itself in the big slot and
push "of N total (P%)" into the small detail line that the other two
columns already use.
- top-starred-repos: the per-row star icon sat at x=306 while the right-
anchored number ended at x=334, so 5+ digit star counts collided with
the icon. Drop the icon (card title already says "Top Starred Repos"),
emit the count as "N ★", right-anchor at x=334 with a 6 px safety gap.
Add a new TestCardsFitFrame stress test that renders every card against an
adversarial profile (10-digit counts, 40-char names, 20 active years,
53-week span) and asserts every positional attribute stays inside the
frame. This is the automated half of the new "fit-the-frame invariant"
added to docs/design-guidelines.md + a pre-release review checklist in
docs/code-standards.md.
Bug reports will still surface text-overflow cases that the coordinate
check can't see (a text-anchor="middle" element has a single x attribute
but renders outward), so the docs also spell out the human-review step:
render dracula against tiny/typical/adversarial fixtures before release.
The dracula sample under output/dracula/ was a reference render for the
README. Now that demo/ auto-generates every card × every theme on each
push, the sample is redundant — and keeping it trackers means every
behavioral tweak shows up as a diff in committed SVGs.
- Delete output/dracula/*.svg.
- .gitignore: collapse `output/*` + `!output/dracula/` to a plain `output/`.
- demo.yml: drop `output/**` from paths-ignore (no longer part of any push).
- README / docs: point readers at demo/ instead of output/dracula/.
Five new cards, all derived from data FetchProductive / FetchProfile already
pull, so zero additional API calls:
- contributions-heatmap: 7×53 calendar grid with a 5-bucket intensity ramp
mixed from each theme's Background→Accent so palettes with no dedicated
heat ramp still render sensibly.
- streak: current streak, longest streak with date ranges, active/total days.
- contributions-by-year: one bar per active year, peak year highlighted.
- productive-weekday + -all-time: 7-bar day-of-week mirror of the hour-of-day
cards; FetchProductive now also fills Weekday / WeekdayAllTime histograms
during the same commit-history pass.
- top-starred-repos: top 5 owned non-fork repos by stargazer count; threads
Stars through RepoInfo.
Card count: 9 → 14. Registered in allCards grouped by recency (last-year
block, then all-time block). Render test extended to cover all new files
and realistic daily-series inputs.
- README points to demo/ as an auto-generated theme preview.
- Bump "60+ / 61 themes" references to the actual 65.
- Record Phase 7.5 in roadmap and list demo.yml + demo/ in layout.
This reverts commit 399a3dc. Repo stays as tiennm99/ghstats; the
Marketplace display name ("ghstats-cards" in action.yml) is the only
place the new name remains, since that field requires uniqueness on
the Marketplace.
plans/reports/* were added alongside the rename in the same commit
and are preserved by not deleting them in this revert.
Matches the Marketplace name; repo is being renamed in lockstep.
- go.mod module path: github.com/tiennm99/ghstats →
github.com/tiennm99/ghstats-cards
- Import paths across every .go file updated.
- README badges, install snippets, and the 'go install' line point
to the new URL/path.
- docs/deployment-guide.md workflow template, Docker image path, and
release edit URL updated.
Breaking for consumers pinned to the old URL; they need to swap
tiennm99/ghstats → tiennm99/ghstats-cards in workflows and switch
Docker pulls to ghcr.io/tiennm99/ghstats-cards. GitHub's HTTP
redirect covers git clones but GHCR does NOT redirect — users must
update image URIs manually.
- Fetcher signatures across codebase-summary and system-architecture
now show the ctx-first arguments and document the rate-limit retry
loop in Client.query.
- Attribution pseudo-code hoists the per-repo total out of the commit
loop to match the current implementation (I6).
- Failure-modes table enumerates primary rate-limit retry, per-year
nil-user warn, and -timeout / Ctrl-C cancellation.
- design-guidelines notes the single-slice donut special case.
- deployment-guide's release section documents the new test gate and
the SHA-pinned Docker/GHA actions; troubleshooting adds the
rate-limit-reset-too-long error. Rate-limit section describes the
sleep-and-retry policy and -timeout flag.
- project-roadmap records Phase 6 (code-review remediation) as done,
renumbers later planned phases, links the new review report.
Files now land at output/<theme>/profile-details.svg etc., without
leading 0-8 prefixes. README authors embed cards by name, so the
lexicographic-sort rationale for the prefix no longer applies.
- All Filename() methods + the allCards ordering comment updated.
- Tests updated to expect the 9 unnumbered filenames.
- README, deployment-guide, codebase-summary, roadmap references
refreshed.
- Dracula sample SVGs regenerated under new names.
