Preview what an update would bring, before anything writes a lock.
thaw reads a flake, resolves its lock as a graph, and reports what would
change if its inputs moved. It writes no flake.lock and deploys nothing.
thaw [subcommand] [flake]
packages which package versions change, appear and disappear
options which NixOS options appear and disappear
--rev-only report which input revisions moved, and evaluate nothing
--input <name> report only what comes from this input
--for <name> report only this subject: a host, devshell, a package
--all report the whole build closure, build tools included
--to <input>=<ref> compare one input against a ref instead of upstream HEAD
--releases look up GitHub releases for the hand-pinned packages
--json machine-readable output
--check exit non-zero when anything moves
Bare thaw runs packages --rev-only. The flake argument defaults to ..
nix run github:oschrenk/thawtask builddirenv allow enters the devShell, which carries go, golangci-lint and
gopls.
