address@hidden: Customizing comint-input-ring-size]

[Richard Stallman]

Could you look at the issue about the misleading message
when :match fails?  Is there a way to specify a different message?
If not, could you add one?

Hello,

I wanted to customize the comint ring size to a value higher than 32
(which is the default), so I tried M-x customize-group RET comint RET.
However, it seems comint-input-ring-size isn't a customization
variable.

Maybe many users would expect to find it as a customization variable
in the 'comint group, or at least be able to change it with M-x
set-variable.  Something like this:

(defcustom comint-input-ring-size 32
  "*Size of input history ring.
"
  :type '(integer :match (lambda (w v) (and (integerp v) (> v 0))))
  :group 'comint)

Do you think it is wise to do so?

By the way, when a user sets this value to -1 (for example) in
customization, the :match function returns nil, which means that -1 is
invalid; however, the message that appears in the echo area isn't that
clear:

custom-variable-set: This field should contain an integer

Is it possible to set a particular message instead of the one above?

Definitely, thanks.
