wild-package-inferred-system

Build Status This library is still in a alpha stage.

wild-package-inferred-system is an extension of ASDF package-inferred-system that interprets star * and globstar ** in package (or system) names.

If you are not sure about package-inferred-system, see the section about it in the ASDF manual. In short, wild-package-inferred-system is aimed at elimininating the need for foo/.../all-type subsystems, which have been manually written only for use-reexporting other .lisp files in the (sub)directories.

Usage

You need to specify the :defsystem-depends-on and :class options to use wild-package-inferred-system as follows:

;; foo-wild/foo-wild.asd
(defsystem "foo-wild"
  :defsystem-depends-on ("wild-package-inferred-system")
  :class "winfer:wild-package-inferred-system"
  :depends-on ("foo-wild/baz/*"))

Each source file in the system foo-wild will begin with defpackage or uiop:define-package in the same way as package-inferred-system:

;; foo-wild/baz/hello.lisp
(uiop:define-package :foo-wild/baz/hello
  (:use :cl :foo-wild/qux/*)
  (:import-from :foo-wild/bar/**/* #:sym1 #:sym2)
  (:export #:hello-world))

The only difference is that wild-package-inferred-system can interpret wildcards in a package name: * matches one directory or (if in the end) any .lisp files in the directory; ** matches zero or more subdirectories. In the above example, the package :foo-wild/qux/* corresponds to the unix path foo-wild/qux/*.lisp and :foo-wild/bar/**/* to foo-wild/bar/**/*.lisp. (The latter path matches all the recursively reachable .lisp files under foo-wild/bar/.)

Since a wild package is just a standard CL package, you can apply find-package, use-package, in-package etc. to it if once generated. Likewise you can apply find-system, load-system or other operations to the corresponding wild system.

You can use any other combinations of wildcards, e.g. foo/*/bar or foo/**/*/interface/*(, though I recommend that you think about if you really need such a complicated desigination).

Dependencies

ASDF version 3.3 or later is required.

wild-package-inferred-system is tested on the (usually latest vesions of the) following implementations: - SBCL - Clozure CL - Allegro CL - ABCL - CLISP - ECL

Installation

FAQ

How can I let a specific file be excluded from wildcard?

wild-package-inferred-system ignores the files whose names begin with dot . or whose types are .nosystem.lisp or .script.lisp even if they match a given wild package.

How can I make a wild package in REPL?

Just call asdf:load-system. Evaluating a form like (asdf:load-system "foo/bar/**/*") will make the wild package and register the corresponding system simultaneously (only if the system foo is wild-package-inferred-system, of course).

Can I use the wildcard * as a part of file or directory name like foo/bar-*-*/*baz?

No. See the issue.

How can I nickname a wild package?

Of course you may manually give arbitrary nicknames to a wild package by e.g. (uiop:ensure-package :foo/bar/* :nicknames '(:foo/bar)).

In addition, wild-package-inferred-system provides an option to nickname a wild package automatically. If :add-non-wild-nickname t is specified in defsystem form, a nickname is given to each wild package, which is the prefix containing no wildcards: e.g. the nickname of :foo/bar/**/baz/* is :foo/bar. Therefore you cannot make two packages with a common prefix (e.g. :foo/bar/**/* and :foo/bar/*) if you enable this option.
