The setting: ASDF

  • build system
  • components
  • operations
  • action graph
  • plan
  • in-memory

Defining components

(defsystem "fare-quasiquote" ... :depends-on ("fare-utils") :components ((:file "packages") (:file "quasiquote" :depends-on ("packages")) (:file "pp-quasiquote" :depends-on ("quasiquote"))))

Modules

(defsystem "fare-utils" ... :components ((:file "package") (:module "base" :depends-on ("package") :components ((:file "utils") (:file "strings" :depends-on ("utils")) ...)) (:module "filesystem" :depends-on ("base") :components ...) ...))

ASDF: summary

  • component = system | module | file $ …
  • a component depends-on other components
  • operation = load-op | compile-op | …
  • operations propagate along the component DAG
  • action = operation x component
  • an action depends-on other actions
  • action DAG ≠ component DAG
  • plan = topologically sorted list of actions
