Returns a string representation of self that may show:

The current position.
The size (in bytes) of the stored string.
The substring preceding the current position.
The substring following the current position (which is also the target substring).

Example

scanner = StringScanner.new("Fri Dec 12 1975 14:39")
scanner.pos = 11
scanner.inspect # => "#<StringScanner 11/21 \"...c 12 \" @ \"1975 ...\">"

If at beginning-of-string, item 4 above (following substring) is omitted:

Example

scanner.reset
scanner.inspect # => "#<StringScanner 0/21 @ \"Fri D...\">"

If at end-of-string, all items above are omitted:

Example

scanner.terminate
scanner.inspect # => "#<StringScanner fin>"
