[fset-devel] Patch to facilitate circular/shared printing.
by Samium Gromoff 04 Jul '11

Scott, The tip of my fset repository[1] ports the four PRINT-WB-{SET,BAG,MAP,SEQ} functions to use PPRINT-LOGICAL-BLOCK, replacing depth/length stops handling and adding circular/shared structure printing. -- 1. git://git.feelingofgreen.ru/fset -- regards, Samium Gromoff -- "Actually I made up the term 'object-oriented', and I can tell you I did not have C++ in mind." - Alan Kay (OOPSLA 1997 Keynote)

[fset-devel] Rereading reader bug for collections with non-NIL defaults.
by Samium Gromoff 01 Jul '11

01 Jul '11

Scott, Evaluation of this form fails with an error: (with-standard-io-syntax (let ((*readtable* (copy-readtable *readtable*)) (v (with-default (map) (set)))) (fset::fset-setup-rereading-readtable *readtable*) (with-input-from-string (s (with-output-to-string (s) (write (list v) :stream s))) (read s)))) ..whereas this succeeds: (with-standard-io-syntax (let ((*readtable* (copy-readtable *readtable*)) (v (map))) (fset::fset-setup-rereading-readtable *readtable*) (with-input-from-string (s (with-output-to-string (s) (write (list v) :stream s))) (read s)))) ...which probably suggests that the reader hasn't been conditioned to take care of the trailing "/foo" syntax. -- regards, Samium Gromoff -- "Actually I made up the term 'object-oriented', and I can tell you I did not have C++ in mind." - Alan Kay (OOPSLA 1997 Keynote)
