Literals

A literal is a value written directly in source code. In Gofra's postfix syntax, a literal pushes its value onto the stack.

42          // pushes 42
0x4124      // pushes 16676
-17         // pushes -17
"hello"     // pushes a string (*string)
'a'         // pushes a char
true        // pushes a bool

Integer literals

Integer literals are written in decimal or hexadecimal:

42
0
-17
0x4124
0xFF

Type: int (8 bytes, signed).

Negative literals

-17 is a single integer literal, not the unary minus applied to 17. The sign is part of the literal.

Hexadecimal

0x4124 is the same value as 16676 in decimal.

Character literals

Character literals use single quotes:

'a'
'Z'
'\n'
'\0'
'\x41'

String literals

String literals use double quotes:

"hello"
""
"Hello, World\n"

Type: *string. See string for details.

Boolean literals

true
false
