Support hash COLLECTIONs, #'{all,try}-completion{s,}; add #'test-completion
src/ChangeLog addition:
2012-01-01 Aidan Kehoe <kehoea@parhasard.net>
Add #'test-completion, API from GNU.
Accept hash table COLLECTIONs in it and in the other
completion-oriented functions, #'try-completion,
#'all-completions, and those Lisp functions implemented in terms
of them.
* lisp.h: Update the prototype of map_obarray(), making FN
compatible with the FUNCTION argument of elisp_maphash();
* abbrev.c (abbrev_match_mapper):
* abbrev.c (record_symbol):
* doc.c (verify_doc_mapper):
* symbols.c (mapatoms_1):
* symbols.c (apropos_mapper):
Update these mapper functions to reflect the new argument to
map_obarray().
* symbols.c (map_obarray):
Call FN with two arguments, the string name of the symbol, and the
symbol itself, for API (mapper) compatibility with
elisp_maphash().
* minibuf.c (map_completion): New. Map a maphash_function_t across
a non function COLLECTION, as appropriate for #'try-completion and
friends.
* minibuf.c (map_completion_list): New. Map a maphash_function_t
across a pseudo-alist, as appropriate for the completion
functions.
* minibuf.c (ignore_completion_p): PRED needs to be called with
two args if and only if the collection is a hash table. Implement
this.
* minibuf.c (try_completion_mapper): New. The loop body of
#'try-completion, refactored out.
* minibuf.c (Ftry_completion): Use try_completion_mapper(),
map_completion().
* minibuf.c (all_completions_mapper): New. The loop body of
#'all-completions, refactored out.
* minibuf.c (Fall_completions): Use all_completions_mapper(),
map_completion().
* minibuf.c (test_completion_mapper): New. The loop body of
#'test-completion.
* minibuf.c (Ftest_completion): New, API from GNU.
* minibuf.c (syms_of_minibuf): Make Ftest_completion available.
tests/ChangeLog addition:
2012-01-01 Aidan Kehoe <kehoea@parhasard.net>
* automated/completion-tests.el: New.
Test #'try-completion, #'all-completion and #'test-completion with
list, vector and hash-table COLLECTION arguments.
