It&#8217;s odd that Emacs has been historically deficient in this area. Magnar Sveen&#8217;s excellent <a href=\"https:\/\/github.com\/magnars\/s.el\">s.el<\/a> has helped fill in the gap and is still more comprehensive than the functions added to the Emacs core but it&#8217;s encouraging that new string functions are being included. I hope we see a unification down the road. <\/p>\n<p> Batsov&#8217;s second post discusses a couple of additions to the <a href=\"http:\/\/emacsredux.com\/blog\/2014\/02\/02\/a-peek-at-emacs-24-dot-4-hash-table-keys-and-hash-table-values\/\">hash table functions<\/a>. These functions, <code>hash-table-keys<\/code> and <code>hash-table-values<\/code>, returns lists of the keys and values in a given hash table. As with Common Lisp, you could always get at these using the <code>maphash<\/code> function but it&#8217;s nice to have some ready made functions. A lot of Elisp functions take a list as input and these functions are a handy way of getting lists of hash keys or values directly without an intermediate step involving <code>maphash<\/code>. <\/p>\n<p> As with Batsov&#8217;s previous posts, these make me look forward to the new Emacs release. We&#8217;re already in feature freeze and should be seeing the first release candidate shortly. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Over at Emacs Redux, the ever informative Bozhidar Batsov has a couple more posts up in his series on the upcoming Emacs 24.4 release.
