charLiteral' :: MonadParser m => m CharSource

This parser parses a single literal character. Returns the literal character value. This parsers deals correctly with escape sequences. The literal character is parsed according to the grammar rules defined in the Haskell report (which matches most programming languages quite closely).

This parser does NOT swallow trailing whitespace.

characterChar :: MonadParser m => m CharSource

stringLiteral' :: MonadParser m => m StringSource

This parser parses a literal string. Returns the literal string value. This parsers deals correctly with escape sequences and gaps. The literal string is parsed according to the grammar rules defined in the Haskell report (which matches most programming languages quite closely).

This parser does NOT swallow trailing whitespace

natural' :: MonadParser m => m IntegerSource

This parser parses a natural number (a positive whole
number). Returns the value of the number. The number can be
specified in `decimal`

, `hexadecimal`

or
`octal`

. The number is parsed according to the grammar
rules in the Haskell report.

This parser does NOT swallow trailing whitespace.

integer' :: MonadParser m => m IntegerSource

This parser parses an integer (a whole number). This parser
is like `natural`

except that it can be prefixed with
sign (i.e. '-' or '+'). Returns the value of the number. The
number can be specified in `decimal`

, `hexadecimal`

or `octal`

. The number is parsed according
to the grammar rules in the Haskell report.

This parser does NOT swallow trailing whitespace.

Also, unlike the `integer`

parser, this parser does not admit spaces
between the sign and the number.

double' :: MonadParser m => m DoubleSource

This parser parses a floating point value. Returns the value of the number. The number is parsed according to the grammar rules defined in the Haskell report.

This parser does NOT swallow trailing whitespace.

naturalOrDouble' :: MonadParser m => m (Either Integer Double)Source

This parser parses either `natural`

or a `double`

.
Returns the value of the number. This parsers deals with
any overlap in the grammar rules for naturals and floats. The number
is parsed according to the grammar rules defined in the Haskell report.

This parser does NOT swallow trailing whitespace.

decimal :: MonadParser m => m IntegerSource

Parses a positive whole number in the decimal system. Returns the value of the number.

hexadecimal :: MonadParser m => m IntegerSource

Parses a positive whole number in the hexadecimal system. The number should be prefixed with "x" or "X". Returns the value of the number.

octal :: MonadParser m => m IntegerSource

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