tiennm99 3fc8a59de6 chore: rename the project to ghglance
The Marketplace rejects ghstats as an action name, so the repo, Go module,
binary, and action share the name ghglance instead. The demo workflow keeps
reading the existing GHSTATS_TOKEN repo secret.

ghglance

Single-binary Go CLI that renders GitHub profile cards as SVG, wrapped by a published GitHub Action. main.go parses flags → internal/github fetches → internal/card renders → internal/theme supplies palettes.

Adding or changing a config knob

A new flag, input, or default is not done when the code compiles. Every knob has a surface in five places, and a change that lands in some but not all of them ships a half-wired feature or a README that lies:

  1. main.go — the CLI flag
  2. action.yml — the matching Action input and its default
  3. entrypoint.sh — the INPUT_* → flag translation
  4. README.md — both reference tables (Action inputs, CLI flags) and the runnable examples: the workflow YAML under "Use as a GitHub Action" and the ghglance … command under "Use as a CLI"
  5. docs/system-architecture.md — when the knob changes the fetch pipeline or its query cost

The examples are the step most often missed, and they are what people copy. Grep the flag name across the repo before calling the change complete; every hit that is a reference table or example should mention it.

Behavior changes are user-visible

The Action is published to the Marketplace, so existing callers get whatever @v1 points at. Default-off for anything that moves numbers on already- rendered cards, and say so in the input description. Releases are tag-driven: push vX.Y.Z, and release.yml tests, builds, and force-moves the floating v1 tag.

Adding a card means updating internal/card/card.go, the card table in README.md, and the layout in .github/workflows/demo.yml — the demo generator embeds a hardcoded list of SVGs, so a new card renders into every theme directory but stays invisible in the gallery until it is added there. Per-theme pages mirror the table layout in the author's profile README at tiennm99/tiennm99.

GitHub API constraints worth remembering

  • commitContributionsByRepository caps at 100 repos per query and truncates silently. Contribution years are queried by quarter, and a saturated quarter is re-asked by month. Only widen windows with that ceiling in mind.
  • contributionCalendar is clipped to the exact from/to, with no week-boundary spillover, so disjoint windows never double-count days.
  • Test files named *_windows_test.go (or any GOOS/GOARCH suffix) are silently excluded from the build on other platforms — go test reports "ok" while running nothing.
