What follows is a listing of the current SRFIs, along with the status of the SRFI in Chicken. Notes appear after the table.

The following statuses are defined.

Notes 1. SRFI-7 compliance is claimed, but nowhere documented in the manual.

2. Only documented under eval-when.

3. Chicken supports a shebang line, but executable names don't comply with SRFI-22.

4. Chicken also implements the now-withdrawn SRFI-12 for error handling.

Withdrawn SRFIs

SRFI Description Status Notes
12 Exception handling builtin 1
85 Recursive equivalence predicates srfi-85

Notes

1. Chicken implements the now-withdrawn SRFI-12 for error handling. Users can install the srfi-34 egg instead.
