@revdep, @revdep-check, @revdep-runtest, @revdep-install

@revdep builds the default alias of every local target that transitively depends on any library defined in the current directory. The reverse dependencies can be other libraries, executables, or tests; Dune walks the dependency graph and schedules the appropriate alias in each dependent directory.

Variants map to other standard aliases in the dependents:

• @revdep-check builds the @check alias of every reverse dependency.

• @revdep-runtest builds the @runtest alias of every reverse dependency.

• @revdep-install builds the @install alias of every reverse dependency.

Usage examples

• dune build @src/revdep builds the default alias of all targets that depend (directly or transitively) on any library declared in src.

• dune build @src/revdep-check builds the corresponding @check alias for those reverse dependencies.

Notes

• These aliases only do work when explicitly requested; they do not add overhead to regular builds.

• If multiple libraries live in the same dune file, their reverse dependencies are combined, so @dir/revdep covers dependents of any library in dir.
