Oh great! I'm going to have to cancel my appearance on "The View"
because of this.
I have mentioned my gripes in the IRC, but for public view I would
love better names for chomp and chop. In isolation those names are
meaningless, so I suggest:
chomp => rtrim
(rtrim "foo\n") => "foo" is much more clear to me, plus it leaves the
door open for trim and ltrim functions should the need arise.
chop => less
(less "foo") => "fo"
(less "foo" 2) => "f"
With less becoming
(defn ^String less
"Cuts n characters from the end of a string returning the resulting
string. If the
number of cuts is greater than the string length, then nothing
happens. When the
number of cuts is not supplied, then the last character is dropped."
([^String s] (less s 1))
([^String s n]
{:pre [(pos? n)]}
(let [cuts (- (count s) n)]
(if (neg? cuts)
s
(subs s 0 cuts)))))
(or http://paste.lisp.org/display/100521 if this is flubbed)
