Chicken SRFI compliance

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.

builtin

the SRFI is provided in the basic Chicken system.

library

the SRFI is provided with the basic Chicken system, but a (use ...) must be performed in order to access it.

egg-name

the SRFI is provided in a separate egg, which can be downloaded via chicken-setup.

NA

the SRFI is not presently available for Chicken. (This doesn't necessarily mean that the SRFI can't be implemented, only that it hasn't been so far.)

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 Chicken also implements the now-withdrawn SRFI-12 for error handling.

Withdrawn SRFIs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 Chicken implements the now-withdrawn SRFI-12 for error handling.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 choose to install the srfi-34 egg instead.
