Guile-Reader - Summary

This group is not part of the GNU Project.

Guile-Reader is a simple framework for building readers for GNU Guile.

The idea is to provide an extensible, yet fast, reader for Guile. Guile already provides facilities for extending its reader (namely `read-hash-extend' and `read-enable') but these seem (i) quite limited and (ii) have a global impact (there is only one instance of `read').

Guile-Reader aims to provide a way to easily define new readers, while still allowing to re-use parts of a standard Scheme reader.  New reader components (called ``token readers'') may be defined either as Scheme procedures or C functions.  It uses GNU lightning (where available) to compile readers to native code, hence allowing to have performance comparable to that of Guile's built-in reader, but with improved maintainability.

Guile-Reader's approach is similar to Common Lisp's ``read table'' but hopefully more powerful and flexible (for instance, one may instantiate as many readers as needed).
