Hi Frank, You are looking for asdf:component-version. See for example how Shuffletron https://github.com/ahefner/shuffletron/blob/39c7d8af6577e9cbd39da656598f98c6eb6c3f14/src/global.lisp#L6 does it
Yes, that is because all components can have versions, not just systems.
Actually, Faré and I have in the past talked about moving the versioning from arbitrary components (including files and modules) up to systems, which is the only place I have seen it used in the wild.
As a half-measure, perhaps we should add SYSTEM-VERSION as an exported function. Having only COMPONENT-VERSION requires users of ASDF to know stuff about the inheritance structure of the COMPONENT subclasses that seems inappropriate.
Best, r

Hello, In the system definition we can specify a version; for example: (asdf:defsystem :foo :description "foo utility" :license "LGPL" :version (:read-file-form "VERSION") :serial t :components ((:file "foo"))) For example I can query the system license like this: (asdf:system-licence (asdf:find-system "foo")) How can I query the version of system foo at run time?
