Subject: Accessing an element in an associativity list
Date: Tue, 9 Sep 2008 06:07:42 -0700 (PDT) [thread overview]
Message-ID: <42fc0e67-edf3-41e1-baea-eab3d46bbf2d@73g2000hsx.googlegroups.com> (raw)
I have the following list of lists structure
(defvar c++-stl-containers
'(
("string" "<string>" "String of char.")
("wstring" "<wstring>" "String of wide char (wchar_t).")
("vector" "<vector>" "Vectors contain contiguous elements stored
as an array.")
)
)
and I want to do something like this:
(index-first 'c++-stl-containers "string" 2)
should evaluate to
"<string>"
Is there any emacs lisp convenience function for accessing a row given
its, say, first (key) element? I know this is slow but speed is of no
importance here. Of course if a hash table is as easy to use then of
course I would like to use that.
Thanks in advance,
Nordlöw
