• File cmd/libfossil/main.go — part of check-in [beed361c03] at 2026-10-19 20:17:37 on branch feat/cli-snapshot — feat(cli): checkout-free snapshot, per-path log, cat --at and diff --json

  repo snapshot commits one file's bytes onto trunk with no checkout, a no-op when they equal the tip. repo log --path lists the check-ins that changed a path, repo cat --at reads a file as a version holds it, and repo diff --json A B [PATH] diffs two versions. Exit 2 means not found. A snapshot re-checks the check-in stamp inside its write transaction and retries, so concurrent processes build one linear trunk.

  Tracked in #451 (user: [email protected], size: 1056) [annotate] [blame] [check-ins using]

// CLI is the top-level command structure.
//
// Version is deliberately a subcommand only, not also a global --version
// flag: `repo extract` already has its own --version flag (the source
// version to extract from), and kong's global flags are visible in every
// subcommand's context, so a root-level --version would collide with it.
// Renaming that existing, unrelated flag to make room isn't part of this
// change.
