Implement print-circle, printing circular structures in a readable
fashion, and treating them appropriately on read. This is by means
of two new object methods, print_preprocess (detecting
circularities), and nsubst_structures_descend (replacing
placeholders with the read objects).
Expose the substitution to Lisp via #'nsubst and its new
:descend-structures keyword.
Store information as to whether symbols are interned in obarray or
not in their header, making checking for keywords and uninterned
symbols (and thus printing) cheaper.
Default print_gensym to t, as Common Lisp does, and as a
more-than-decade old comment suggests.
lisp/ChangeLog addition:
2011-09-04 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el (byte-compile-output-file-form):
* bytecomp.el (byte-compile-output-docform):
Bind print-circle, print-continuous-numbering in these functions,
now those variables are available.
* lisp.el (forward-sexp):
* lisp.el (backward-sexp):
Recognise leading #N= as being part of an expression.
tests/ChangeLog addition:
2011-09-04 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-reader-tests.el:
* automated/lisp-tests.el (literal-with-uninterned):
* automated/symbol-tests.el (foo):
Test print-circle, for printing (mutually-)recursive and circular
structures.
Bind print-continuous-numbering where appropriate.
