character
representing
backspace
. On most
terminal
s this just moves the
cursor
one
cell
to the
left
(and even then it is unspecified what happens when the cursor is on the first cell of the
line
). On a
hardcopy
terminal
(lacking
TypEx
)
, the next character will
overprint
. So
"a\b_b\b_c\b_"
or
"abc\b\b\b___"
might be printed as
abc
, and
"a\bab\bbc\bc"
or
"abc\b\b\babc"
might be printed as
abc
.
In
Perl
regexp
s, a
zero-width
"
assertion
" matching at the
boundary
between a
word character
(see
\w
) and a non-word
character
(see
\W
, which unfortunately shares the same
E2 node
). For instance, to find all occurances of the word "
the
", use "
m
/\bthe\b/". "m/the/" doesn't work, because it also finds "
mo
the
r
"; "m/\Wthe\W/" also doesn't work, because it fails to find "
the
" when situated at the very beginning or end of the
string
.
(It
is
possible to write an appropriate regexp which does this correctly, but it is much longer-winded than would be sensible to write...)
