A second goreleaser build links a Windows binary for the GUI subsystem
(-H windowsgui) and ships it as kage_<version>_windows-gui_<arch>.zip, scoped so
the package managers still install the console build. Packing a viewer onto this
base gives a double-click .exe with no console behind it. A CI job cross-compiles
the windowsgui link so it cannot rot.
The GitHub Ubuntu runner disables unprivileged user namespaces with
AppArmor, so Chrome's sandbox cannot initialize and the new secure
default (sandbox on) makes Chrome refuse to start. IN_DOCKER is the
documented escape hatch for that case, so set it on the Ubuntu leg of
the test job. It also exercises the container code path. macOS does not
need the flag, so it stays empty there.
The gofmt gate listed packages by hand and missed pack, zim, and viewer, so a
formatting slip in the newer code would sail through. Check the whole module
instead. Add a macOS job that compiles the -tags webview viewer, the cgo path
the pure-Go CI never builds; the viewer code is identical across platforms, so
one compile guards it. Also note the new base-OS detection in the docs.
kage renders every page in headless Chrome, snapshots the final
DOM, strips all JavaScript, and localises CSS, images, and fonts
so a site can be browsed offline as a plain folder of files.
The engine is split into small packages:
urlx deterministic URL to local-path mapping and scope rules
sanitize remove scripts, on* handlers, and javascript: URLs
asset rewrite HTML and CSS references, download assets
browser headless Chrome pool over the DevTools protocol
robots robots.txt matcher
clone the orchestrator: a polite resumable breadth-first crawl
The cli package wires a cobra and fang command surface with two
commands, clone and serve. Every pure package has table tests; the
browser and clone packages add Chrome-driven end-to-end tests that
skip when no browser is present or under -short.
CI runs gofmt, vet, build, race tests, golangci-lint, govulncheck,
and a tidy check on Linux and macOS. A goreleaser config fans one
tag out to archives, deb/rpm/apk, a Chromium-bundled GHCR image,
and the package managers. A tago docs site builds to Pages and
Cloudflare.
