Felix literals.


Digits may be separated by an underscore. Prefix and suffix letters may be upper or lower case.

Prefix denotes radix, default decimal:
0b binary

0o octal

0d decimal

0x hexadecimal

Suffix denotes type, default int:

t tiny (C char)

s short (C short)

i int (C int)

l long (C long)

v vlong (C long long)

u unsigned, with one of above

i8 u8 8 bit (C99 int8_t)

i16 u16 16 bit (C99 int16_t)

i32 u32 32 bit (C99 int32_t)

i64 u64 64 bit (C99 int64_t)

Subexpressions involving the operators:

unary + identity

unary - negation

binary + addition

binary - suibtraction

binary * suibtraction

binary / quotient

binary % remainder

binary < <= == != => ? comparison

and integral literals of type int, are calculated at compile time (constant folding).


Python style strings may use single or double quotes, singly or tripled:

' .. '

''' .. ''' spans lines

" .. "

""" .. """ spans lines

r raw string, no escape processing

u UCS-4 (32 bit) string

c 8 bit C null terminated C string, of
type cptr[char] = 'char const*'


\n \r \b \t \v \f Newline, return, bell, tab, vertical tab, formfeed: as in C.

ISO-10646/Unicode code point, given in hex. For 8 bit strings, replaced with UTF-8 encoding.
Note: no \999 or \xXX escapes are supported. ,br Note: there are no character literals.

Special concatenation forms.
Note these apply to string expressions, not just literals; if literals are used, concatenation is done at compile time (constant folding).

<string> <string> ...
concatenate strings.

<string> <integer> ...
append ISO-10646 code point, use UTF-8 encoding for 8 bit strings.


Floats consist of two digit strings separated by a decimal point, and possibly an exponent. The digit strings may be separated by single underscores. An exponent is the letter E or e followed by a decimal digit string, underscores are not allowed, however an underscore may separate the mantissa from exponent.
Suffix denotes type, default double:
f float

d double

l ldouble

Exponent kind:
e power of 10

p power of 2

Prefix denotes radix, default decimal:
x Hexadecimal
