octal

octal = base 8

Parses a non-negative whole number in the octal system. The number should be prefixed with "o" or "O". Returns the value of the number.

Parse an integer in the octal representation. The format of the octal number is expected to be according to the Haskell report except for the fact that this parser doesn't parse “0o” or “0O” prefix. It is a responsibility of the programmer to parse correct prefix before parsing the number itself. For example you can make it conform to the Haskell report like this:

octal = char 48 >> char' 111 >> L.octal

Warning: this function does not perform range checks.

It is a responsibility of the programmer to parse correct prefix before parsing the number itself. For example you can make it conform to the Haskell report like this:

octal = char '0' >> char' 'o' >> L.octal

Note: before version 6.0.0 the function returned Integer, i.e. it wasn't polymorphic in its return type. Warning: this function does not perform range checks.

Octal representation of an integer.

>>> octal @Int32 123456
"00000361100"

>>> octal @Int32 (-123456)
"77777416700"

Recognize an octal number. Must have a prefix of the form 0o/0O.

>>> octal
(re.++ (re.union (str.to.re "0o") (str.to.re "0O")) (re.+ (re.range "0" "7")))

>>> prove $ \s -> s `match` octal .=> sAny (.== take 2 s) ["0o", "0O"]
