CLDM is a distributed dependency manager for Common Lisp.
Its design is similar to that of Smalltalk Metacello. But unlike Metacello, it allows version constraints (like <, <=, >=, >) and solves them using Pseudo Boolean Optimization (PBO) as described in this paper. Library dependencies are encoded to PBO and a PBO solver is run afterwards optimizing to get the newest versions of libraries. minisat+ is the PBO solver being used at the moment, but support for others like sat4j is also planned.
Common Lisp libraries and its versions are described in .cld files, that should be made accessible to CLDM somehow (url, filesystem, git)
Then CLDM download the exact versions of dependencies for a given library and version, and puts them in a filesystem directory. After that, pushes their .asd definitions to asdf:*central-registry* and from that point on asdf is in charge.
For instance, here is the library description .cld file for some versions of the Hunchentoot CL web server:
;;; -*- Mode: LISP; Syntax: COMMON-LISP; Package: CL-USER; Base: 10 -*-

BORDEAUX-THREADS. It supports HTTP 1.1, serves static files, has a
simple framework for user-defined handlers and can be extended
through subclassing."

This is in alpha but if you still want to try it out, it can almost load Hunchentoot at the moment.
Download CLDM from https://github.com/cldm/cldm
git clone git@github.com:cldm/cldm.git
CLDM depends on **SBCL** and minisat+ so you need to install to be able to build.
On a Ubuntu based Linux system:
sudo apt-get install sbcl
sudo apt-get install minisat+
CLDM currently depends on the following Common Lisp libraries:
The best way to obtain them is via Quicklisp
Make CLDM loadable by adding it to quicklisp local-projects, or from SBCL systems directory:
cd ~/quicklisp/local-projects
ln -s <cldm directory>/cldm.asdf
or:
cd ~/.sbcl/system
ln -s <cldm directory>/cldm.asdf
Now you should be able to build the command line binary:
sh make.sh
And then install it:
sudo sh install.sh
Finally, you can try to install a library:
cldm install hunchentoot
CLDM will calculate the required library versions and download them.
Although CLDM is distributed in nature, there’s central repository in progress here: http://cldm.github.io/cldm-repo for generally useful Common Lisp libraries. CLDM fetches .cld definitions from there if isn’t told otherwise.
