chicken-edn
An EDN reader and writer for R7RS compatible Schemes.
Installation: chicken-install edn
Data type conversions
- All kinds of numbers get converted to Scheme numbers, precision suffixes (N and M) get ignored.
- Keywords :keyword get converted to chicken scheme keywords keyword:.
- Maps get converted to SRFI 69 hashtables.
- Vectors are srfi-4 vectors.
- true = #t, false = #f, nil = '()
Missing reader functionality
Should you notice missing functionality of the reader, plesase use the issues page to report it and, if possible, provide a minimal test case.
API
- Transforming EDN into Scheme:
(read-edn <port>)
- Transforming Scheme into EDN:
(write-edn <port> <datastructure>)
- Using reader tags: the library contains a parameter
tag-handlers
containing an a-list. To register a handler, add an a-list entry where the key is the tag without\#
and as a keyword, and the value a one-argument procedure.
Releases
- 1.1: Port to Chicken 6.
- 1.0: Made the custom parsers a parameter.
- 0.5.2: Update for Chicken 5
- 0.5.1: Small compatibility improvements: "/" now starts a symbol as well, and "," is treated as whitespace.
- 0.5: Reader tag support.
- 0.4: Complete rewrite. Only relies on R7RS, and SRFI 1, 4, 69 and 88. Uses ports. Reads and writes EDN.
- 0.3: EDN tags, including special forms, work. #inst and #uuid both get read as strings. Add nil. Add number prefixes. Add no-space-required to #_ tag.
- 0.2.1: Can read EDN-files and -strings. EDN tags are not working yet.
- 0.2: Can read EDN-strings with one top-level data structure.
