annotate src/widget.c @ 4792:95b04754ea8c
Make #'equalp more compatible with CL; add a compiler macro, test & doc it.
lisp/ChangeLog addition:
2009-11-08 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (cl-string-vector-equalp)
(cl-bit-vector-vector-equalp, cl-vector-array-equalp)
(cl-hash-table-contents-equalp): New functions, to implement
equalp treating arrays with identical contents as equivalent, as
specified by Common Lisp.
(equalp): Revise this function to implement array equivalence,
and the hash-table equalp behaviour specified by CL.
* cl-macs.el (equalp): Add a compiler macro for this function,
used when one of the arguments is constant, and as such, its type
is known at compile time.
man/ChangeLog addition:
2009-11-08 Aidan Kehoe <kehoea@parhasard.net>
* lispref/objects.texi (Equality Predicates):
Document #'equalp here, as well as #'equal and #'eq.
tests/ChangeLog addition:
2009-12-31 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test much of the functionality of equalp; add a pointer to Paul
Dietz' ANSI test suite for this function, converted to Emacs
Lisp. Not including the tests themselves in XEmacs because who
owns the copyright on the files is unclear and the GCL people
didn't respond to my queries.
