Lockfile behavior​

The lockfile is considered up to date when the [dependencies] and [dev-dependencies] in mops.toml haven't changed since the lockfile was last written.

  • Lockfile up to date — installs the exact versions recorded in the lockfile, skipping dependency resolution.
  • Lockfile missing or out of date — runs full dependency resolution, installs resolved versions, then creates/updates the lockfile.

See mops.lock for details on lockfile contents and when to commit it.

Options​

--lock​

What to do with the lockfile.

Possible values:

  • update — keep the lockfile in sync with current dependencies and verify file integrity (default). Pass explicitly to force regeneration if the lockfile is stale or corrupt.
  • check — verify file integrity against an existing lockfile; fail if the lockfile is missing or out of date
  • ignore — skip the lockfile entirely

--no-toolchain​

Do not install toolchain.

--verbose​

Verbose output.

CI​

In CI environments (CI env var is set), the default --lock mode is check instead of update — the lockfile is never auto-created in CI. If no lockfile is present in CI, integrity checking is silently skipped.

See CI environments on the mops.lock page for full details.
