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.

The files in this directory contain source code for the core XEmacs facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc files are byte-compiled versions of the corresponding *.el files. Byte-compiled files are architecture-independent. Functions used only by files in this directory are considered "internal" and are subject to change at any time. All commands, and most functions with docstrings, are part of the exported API. In particular, it is considered good style to use the Common Lisp facilities provided in cl*.el. (Yes, that's ambiguous. Sorry, we don't have a full specification of the API, as the Lispref is chronically incomplete. Anything described in the Lispref is part of the API, of course.) Libraries which implement applications and enhancements are placed in the "packages", which are distributed separately from the core sources. #### Someone please update this. #### Partially updated 2001-08-25 by sjt. Needs more work. Mike? When XEmacs starts up, it adds certain directories in various hierarchies containing Lisp libraries to `load-path' (the list of directories to be searched when loading files). These are: this directory, its subdirectory ./mule (in Mule-enabled XEmacs only), the site-lisp directory (deprecated), and all the lisp/PACKAGE subdirectories of the xemacs-packages, mule-packages, and site-packages hierarchies. See setup-paths.el. #### Is the following true or relevant any more? bogus> Directories whose names begin with "-" or "." are not added to bogus> the default load-path. Some files which you might reasonably want to alter when installing or customizing XEmacs at your site are: paths.el You may need to change the default pathnames here, but probably not. This is loaded before XEmacs is dumped. site-init.el #### obsolete and removed? To pre-load additional libraries into XEmacs and dump them in the executable, load them from this file. Read the instructions in this file for a description of how to do this. site-load.el #### description is obsolete This is like site-init.el, but if you want the docstrings of your preloaded libraries to be kept in the DOC file instead of in the executable, you should load them from this file instead. To do this, you must also cause them to be scanned when the DOC file is generated by editing ../src/Makefile.in.in and rerunning configure. #### new semantics This file will preload additional libraries listed in ../site-packages and dump them into XEmacs. ../site-packages List of additional libraries read by site-load.el. site-start.el This is loaded each time XEmacs starts up, before the user's .emacs file. (Sysadmin must create.) Can be inhibited for a given invocation with `--no-site-file'. default.el This is loaded each time XEmacs starts up, after the user's .emacs file, unless .emacs sets the variable inhibit-default-init to t. (Sysadmin must create.) Can be inhibited for a given invocation with `-q'. version.el This contains the version information for XEmacs. ======================================================================== Original text follows: The files in this directory contain source code for the XEmacs facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc files are byte-compiled versions of the corresponding *.el files.
