Variable `minibuffer-completion-table' is an internal variable used in Emacs completion operations. It can take several forms, such as an alist, an obarray (vector), a list of strings, and a hash table (it can also be a function).
Can someone tell me when (where) `minibuffer-completion-table' takes the form of a hash table for Emacs completion? That is, besides passing `all-completions' or `try-completion' a hash table of my own, where is a hash table used in vanilla Emacs (for completion)? Are obarrays sometimes implemented as hash tables, for example, or do they always take the form of vectors? In sum, if I grab `minibuffer-completion-table' at random during a completion operation, under what circumstances is it likely to be a hash table? Thanks. _______________________________________________ Help-gnu-emacs mailing list Help-gnu-emacs@gnu.org http://lists.gnu.org/mailman/listinfo/help-gnu-emacs
