7.2. Character

A character is a signed 8-bit value. A character can be represented by an i8 in MLIR.

7.2.1. Declaration

A character value is declared with the keyword character.

7.2.2. Literals and Escape Sequences

A character literal is written in the same manner as C99: a single character enclosed in single quotes. For example:

'a'
'b'
'A'
'1'
'.'
'*'

As in C99, Gazprea supports character escape sequences for common characters. For example:

'\0'
'\n'

The following escape sequences are supported by Gazprea:

Description	Escape Sequence	Value (Hex)
Null	\0	0x00
Bell	\a	0x07
Backspace	\b	0x08
Tab	\t	0x09
Line Feed	\n	0x0A
Carriage Return	\r	0x0D
Quotation Mark	\"	0x22
Apostrophe	\'	0x27
Backslash	\\	0x5C

7.2.3. Operations

The following operations are defined between character values.

Class	Operation	Symbol	Usage	Associativity
Grouping	parentheses	()	(character)	N/A
Comparison	equals	==	character == character	left
	not equals	!=	character != character	left

Scalar values with type character may be concatenated onto variables with type string or arrays with type character.

7.2.4. Type Casting and Type Promotion

To see the types that character may be cast and/or promoted to, see the sections on Type Casting and Type Promotion respectively.
