Arguments: name &optional (errorp t)
The default for the errorp argument was changed
from nil
to t
in
release 8.2.
This function looks up a readtable by
name. name must be a symbol, but it is coerced to
a keyword (so readtables are named by
keywords). setf may be used to associate a name to
a readtable. The association can be broken by setting to nil
. Naming readtables is particularly useful for
editors (see the description of Emacs file mode line support for named
readtables in eli.htm).
This function returns the readtable named by
name. If no such readtable exists, this function
returns nil
if errorp is
nil
and signals an error if
errorp is true (the default).
Here is an example:
user(2): (setq my-rt (copy-readtable)) #<readtable @ #x4d4fa2> user(3): (setf (named-readtable :mytable) my-rt) #<readtable @ #x4d4fa2> user(4): (named-readtable :mytable) #<readtable @ #x4d4fa2> user(5): (setf (named-readtable :mytable) nil) nil user(6): (named-readtable :mytable nil) nil user(7): (named-readtable :mytable) Error: There is no readtable named :mytable. [1] user(8):
