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/.

## Module responsibilities
|
||
|
||
### `internal/github`
|
||
|
||
All network I/O. Exposes a `*Client` with three fetchers; every call takes a `context.Context` so pagination aborts cleanly on timeout or Ctrl-C:
|
||
|
||
| Fetcher | Input | Populates |
|
||
| --- | --- | --- |
|
||
| `FetchProfile(ctx, login, opts)` | username, visibility flags | Profile basics, totals, owned-repos aggregation, last-year daily calendar, `TopRepos` |
|
||
| `FetchContributionsAllTime(ctx, p, opts)` | Profile | `SeedRepos`, `DailyContributionsAllTime`, `TotalCommitsAllTime` |
|
||
| `FetchProductive(ctx, p, repos, loc, cap)` | Profile + seed + tz + cap | `Productive`, `CommitsByLanguage`, `ProductiveAllTime`, `CommitsByLanguageAllTime` |
|
||
|
||
Call order in `main.go`: Profile → AllTime → Productive. `Client.query` handles GitHub rate limits transparently — on 429 or 403 with `X-RateLimit-Remaining: 0`, it honors `Retry-After` / `X-RateLimit-Reset` (capped at 5 minutes) and retries once.
|
||
|
||
### `internal/card`
|
||
|
||
Pure rendering. Every card implements the `Card` interface:
|
||
|
||
```go
|
||
type Card interface {
|
||
Filename() string
|
||
SVG(*github.Profile, theme.Theme) ([]byte, error)
|
||
}
|
||
```
|
||
|
||
`RenderAll` iterates `allCards`, writes each to `<outDir>/<themeID>/<Filename>`.
|
||
|
||
Shared helpers:
|
||
- `renderDonutCard` — language donut + legend (used by 3 language cards)
|
||
- `renderProductiveTime` — 24h bar chart (used by both productive cards)
|
||
- `renderContributions` — smooth area chart (used by both contributions cards)
|
||
- `header`, `footer` — SVG chrome
|
||
- `niceTicks`, `formatTick` — axis math
|
||
|
||
### `internal/theme`
|
||
|
||
Static map of 65 themes. Each theme specifies title/text/background/stroke/accent/muted plus `StrokeOpacity` for correct light-theme borders.
|
||
|
||
## Card ↔ data flow
|
||
|
||
```
|
||
profileQuery ─────► Profile.{identity, owned repos, totals, last-year calendar}
|
||
│
|
||
contributionYearQuery ─┬──► SeedRepos + DailyContributionsAllTime + TotalCommitsAllTime
|
||
│
|
||
└─ seed into ─►
|
||
│
|
||
commitHistoryQuery ──► Productive + CommitsByLanguage (+ AllTime variants)
|
||
│
|
||
▼
|
||
14 SVG files per theme
|
||
```
|
||
|
||
## Test coverage
|
||
|
||
- `internal/card/card_test.go` — `RenderAll` produces 14 valid SVGs; XML escape through real render pipeline; `formatInt` cases; `TestDonutSingleSlice` (guards the empty-arc regression); `TestDonutEmpty` (no-data fallback).
|
||
- `internal/github/profile_test.go` — `sortLangStats` ordering and tiebreak.
|
||
- `main_test.go` — `TestUTCOffsetLabel` covers UTC, Asia/Saigon, half-hour (Kolkata), quarter-hour (Kathmandu) zones.
|
||
|
||
No network-touching tests; real runs verified via `-token` + local build.
|
||
|
||
## Naming conventions
|
||
|
||
- Go files use snake_case for multi-word names (`repos_per_language.go`, `contributions_all_time.go`).
|
||
- Cards' `Filename()` returns a plain kebab-case name (`profile-details.svg`, `most-commit-language-all-time.svg`, …). Embedders reference by name, so no numeric prefix is needed.
|
||
- Themes in snake_case to match upstream (`github_dark`, `nord_bright`).
