guid75/ziplist/1.0.0

NOTE: the latest version is 1.0.2

Rerouted (renamed, needs approval). The GitHub user or repository was renamed. The tag is still there, at the new name. The Lamdera package server serves a copy recovered from https://github.com/Guid75/ziplist.

What we checked: The repo moved to github.com/Guid75/ziplist and tag 1.0.0 is there; its commit 802f360d424d is from 2018-08-21 20:21 UTC, after the version was published (2018-08-21 16:37 UTC); elm.json is byte-identical to package.elm-lang.org's; the exposed modules match docs.json; the zip's SHA-1 is not the published one and nothing else confirms its contents.

We could not verify this copy against what was published, so the Lamdera compiler asks before using it (y/n). Without a terminal, as in CI, it stops with an error unless approved:

  • lamdera make --auto-approve-package-rerouting approves rerouted versions for that run,
  • LAMDERA_AUTO_APPROVE_PACKAGE_REROUTING=1 does the same for every run in that environment,
  • LAMDERA_CACHE=off skips the Lamdera package server altogether: packages come from package.elm-lang.org and GitHub only, as with elm, and a rerouted version then fails to download.
