opam-lock: restrict opam file to describe a precise build environment
This small opam plugin can rewrite opam package definition files to emulate the behaviour of so-called "lock files" present in many package managers.
It reads opam files, extracts the precise set of their dependencies that is
currently installed, as well as pins and non-installed optional dependencies,
and writes back a <name>.opam.locked file that enforces this set and has the
corresponding pin-depends:.
You can then use opam install <name>.opam.locked to get the package installed
with the precise dependencies, including transitive dependencies, that it had in
the original system.
Option --direct-only can be used to only lock direct dependency versions
rather than the whole tree.
Note that the locked opam file adds conflicts to uninstalled optional dependencies, but not recursively: it therefore guarantees the same dependencies get installed, up to potentially some of their optional dependencies.
This project is currently in early beta.
