SRFI 38: I/O for data with shared structure

This egg provides forms for reading and writing data containing shared structure. By using these forms, circular lists and similar data can be printed and read reliably, something that is impossible in vanilla CHICKEN.

In addition to the SRFI forms, this egg also provides REPL support for shared structure I/O via the make-repl-support-shared-structure procedure.

SRFI Description

This page is intended to document the forms exported by this egg. For a full description of SRFI 38, see the SRFI document.

Documentation

See SRFI-38 document.

This implementation extends write-with-shared-structure to accept the optional keyword parameter #:ignore-strings, which is true will treat strings as normal (nonshared) objects even if repeated.

The utility `make-repl-support-shared-structure' is also provided to support printing results at the REPL with shared structure.
