ASDF: Another System Definition Facility

For all information about ASDF, see the web page: https://common-lisp.net/project/asdf/

Notably read the manual for instructions on how to use it: https://common-lisp.net/project/asdf/asdf.html

Repository of this remote ECL branch: https://gitlab.common-lisp.net/ecl/asdf

This file is only a guide for new developers.

[TOC]

Building ASDF

First, make sure ASDF is checked out under a path registered by the source-registry, if that isn't the case yet (see the manual). One place would be:

~/.local/share/common-lisp/source/asdf/

or, assuming your implementation provides ASDF 3.1 or later:

~/common-lisp/asdf/

If you cloned our git repository, rather than extracted a tarball, bootstrap a copy of build/asdf.lisp with:

make

Building the documentation

The manual is also in the doc/ subdirectory, and can be prepared with:

make -C doc

Testing ASDF

Before you may run tests, you need a few CL libraries. The simplest way to get them is as follows, but read below:

make ext

NOTA BENE: You may also need to run make ext again after you git pull or switch branch, to update the ext/ directory. This unhappily is not automatic. If for some reason tests fail, particularly due to an error compiling, loading or running a library, then run make ext and try again.

The above make target uses git submodule update --init to download all these libraries using git. If you don't otherwise maintain your own set of carefully controlled CL libraries, that's what you want to use. However, it is only available if you have a git checkout of ASDF; not if you used a tarball. If you use a tarball or otherwise do maintain your own set of carefully controlled CL libraries then you will want to use whichever tools you use (e.g. quicklisp, clbuild, or your own scripts around git) to download these libraries: alexandria, asdf-encodings, cl-launch, closer-mop, cl-ppcre, cl-scripting, fare-mop, fare-quasiquote, fare-utils, inferior-shell, lisp-invocation, named-readtables, optima.

If you are a CL developer, you may already have them, or may want to use your own tools to download a version of them you control. If you use Quicklisp, you may let Quicklisp download those you don't have. In these cases, you may NOT want to use the git submodules from make ext. Otherwise, if you want to let ASDF download known-working versions of its dependencies, you can do it with:

make ext

Once you have all the required libraries and the asdf-tools script can find a suitable Common Lisp implementation, you may run all the tests on a given Common Lisp implementation $L, with your favorite installed system $S, using:

make t u l=$L s=$S

To run only the regression test scripts, try simply:

make l=$L test-scripts

Lisp Scripting test system

ASDF by default uses a shell script in ./test/run-tests.sh to run the scripts that orchestrate its tests.

An alternate build and test system using Common Lisp as a scripting language is available. It is disabled by default because the new maintainer is having trouble with it in his environments. It worked fine for the previous maintainer in his environments, and may be particularly useful on Windows if and when the shell-based test system fails. Its source code is in tools/ and it can invoke using the script make-asdf.sh, or, on Windows, make-asdf.bat.

To use this alternate test system, pass to make the extra arguments -f Makefile-lisp-scripting as in for instance:

make -f Makefile-lisp-scripting t l=sbcl

Or you can make that your local default (assuming GNU make) using:

ln -s Makefile-lisp-scripting GNUmakefile

These Lisp tools by default use Clozure Common Lisp (CCL) to build and run a binary build/asdf-tools that will orchestrate the tests. By defining and exporting the variable LISP to be one of ccl, sbcl or allegro, you can have it use an alternate Common Lisp implementation instead. Install CCL (respectively SBCL or Allegro) and make sure an executable called ccl (respectively sbcl or alisp) is in your PATH, or that you export a variable CCL (respectively SBCL or ALLEGRO) that points to the executable. To use a further Common Lisp implementation, suitably edit the script tools/asdf-tools, or, on Windows, the batch file tools/asdf-tools.bat. (Note that as of SBCL 1.2.13, we recommend against using SBCL on Windows for that purpose.)

Note that the executable build/asdf-tools is being built the first time you test ASDF. When you update ASDF, via e.g. git pull or a branch switch, you may have to update it, with:

make -f Makefile-lisp-scripting build-asdf-tools

The reason this is not done automatically every time is because building it depends on a working ASDF; but when you're modifying ASDF and testing it, you cannot rely on a working ASDF: indeed, a developer may not only make mistakes, but may deliberately introduce or re-introduce bugs at some place to test code in another place.

Debugging ASDF

To interactively debug ASDF, you may load it in such a way that M-. will work, by installing the source code, and running:

(asdf:load-system :uiop) ;; loading uiop is simple
(map () 'load ;; loading asdf/defsystem is tricky
 (asdf:input-files :concatenate-source-op "asdf/defsystem"))

Note that the above can be adapted in a general recipe to get all the files in a system, in order. To also have the files in systems it transitively depends on, add the :other-systems t keyword argument to the call to asdf::required-components.

To interactively use the asdf-tools, you need to either have all its dependencies installed and configured. If you're using them through the ext/ directory and make ext, then you may need to emulate what the script in tools/asdf-tools does with respect to initializing the source-registry. Note that it also declares a system for cl-launch/dispatch; you can either do something similar, or expand the source for cl-launch with make -C ext/cl-launch source so cl-launch.asd will be created.

How do I navigate this source tree?

  • asdf.asd

    • The system definition for building ASDF with ASDF.
  • *.lisp

    • The source code files for asdf/defsystem. See asdf.asd for the order in which they are loaded.
  • uiop/

    • Utilities of Implementation- and OS- Portability, the portability layer of ASDF. It has its own README, and functions all have docstrings.
  • Makefile

    • a minimal Makefile for bootstrap and development purposes. Most of the logic is in the asdf-tools system below.
  • tools/

    • asdf-tools, a system to build, test and release ASDF. It includes:
      • asdf-tools -- a shell script to run it as a shell command.
      • asdf-tools.bat -- a Windows batch file to run the above.
      • asdf-tools.asd -- system definition for asdf-tools
      • *.lisp -- the source code for the asdf-tools system, except for the few files below.
    • also a couple scripts to help ASDF users:
  • Makefile-lisp-scripting, make-asdf.sh and make-asdf.bat

    • Makefile and scripts to invoke the lisp scripting variants of the build system.
  • version.lisp-expr

    • The current version. Bumped up every time the code changes, using:

      make bump
  • doc/

  • test/

    • regression test scripts (and ancillary files) for developers to check that they don't unintentionally break any of the functionality of ASDF. Far from covering all of ASDF, but a good start.
  • contrib/

    • a few contributed files that show case how to use ASDF or help with debugging it or debugging programs that use it.
  • debian/

    • files for packaging on Debian, Ubuntu, etc. (now only present in the debian branch).
  • build/

    • where the Makefile and asdf-tools store their output files, including
      • asdf.lisp -- the current one-file deliverable of ASDF
      • asdf-XXX.lisp -- for upgrade test purposes, old versions
      • results/ -- logs of tests that have been run
      • fasls/ -- output files while running tests.
  • ext/

    • external dependencies, that can be populated with make ext or equivalently with git submodule update --init. Depopulate it with make noext or equivalently with: submodule deinit .
  • README.md

    • this file.
  • TODO

    • plenty of ideas for how to further improve ASDF.
