2.1 Implemented SRFIs

Kawa implements the following semi-standard SRFIs (Scheme Request for Implementation):

• SRFI 0: Feature-based conditional expansion construct, using cond-expand - see Syntax and conditional compilation.
• SRFI 1: List Library, if (require 'list-lib) - see SRFI-1.
• SRFI 2: AND-LET*: an AND with local bindings, a guarded LET* special form.
• SRFI 4: Homogeneous numeric vector datatypes - see Uniform vectors.
• SRFI 6: Basic String Ports - see Ports.
• SRFI 8: receive: Binding to multiple values - see Multiple values.
• SRFI 9: Defining Record Types, using define-record-type - see Record types.
• SRFI 10: #, external form for special named types. This is deprecated for various reasons, including that it conflicts with syntax-case unsyntax. Better to use srfi-108 Named quasi-literals.
• SRFI 11: Syntax for receiving multiple values, using let-values and let*-value - see Multiple values.
• SRFI 13: String Library. Needs some polishing.
• SRFI 14: Character-set Library - see Character sets.
• SRFI 16: Syntax for procedures of variable arity, using case-lambda.
• SRFI 17: Generalized set! - see Locations.
• SRFI 23: Error reporting mechanism, using error - see Exceptions.
• SRFI 25: Multi-dimensional Array Primitives - see Arrays.
• SRFI 26: Notation for Specializing Parameters without Currying - see Procedures.
• SRFI 28: Basic Format Strings - see Format.
• SRFI 30: Nested Multi-line Comments.
• SRFI 35: Conditions.
• SRFI 37: args-fold - a program argument processor, if (require 'args-fold).
• SRFI 38: External Representation for Data With Shared Structure. The read-with-shared-structure is missing, but subsumed by read.
• SRFI 39: See Parameter objects.
• SRFI 41: Streams - see Streams.
• SRFI 45: Primitives for Expressing Iterative Lazy Algorithms - see Lazy evaluation.
• SRFI 60: Integers as Bits. - see Logical Number Operations.
• SRFI 62: S-expression comments.
• SRFI 64: A Scheme API for test suites.
• SRFI 69: Basic hash tables - see Hash tables.
• SRFI 87: => in case clauses.
• SRFI 88: Keyword objects - see Keywords.
• SRFI 95: Sorting and Merging.
• SRFI 97: Names for SRFI Libraries.
• SRFI 98: An interface to access environment variables
• SRFI 101: Purely Functional Random-Access Pairs and Lists - see SRFI-101.
• SRFI 107: XML reader syntax - see XML literals.
• SRFI 108: Named quasi-literal constructors - see Named quasi-literals.
• SRFI-109: Extended string quasi-literals - see string quasi-literals.
• SRFI-118: Simple adjustable-size strings (string-append! and string-replace!).
