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.
