cl-treemaps
cl-treemaps is a lightweight and fast implementation of binary trees. The current version only features red black trees. The interface is similar to the one of Common Lisp Hash Maps and is therefore very easy to understand and use. See the README for further details. The package is only tested with SBCL.

The sourcecode is hosted on github (github.com/sake/cl-treemaps). Tarballs can also be found there.

This package does not implement the Treemapping method for displaying tree-structured data by using nested rectangles.

Quick assessment (2023-03-19)

  • Compiles without warnings in CCL.
  • Fails the test due to type declaration.
