Strings

String literals are delimited by either single quotes (') or double quotes ("). Both forms are identical in behaviour.

"hello"
'world'
"It's a string"
'She said "hi"'

Escape sequences

The following escape sequences are recognised within string literals:

Sequence	Meaning
\n	Newline
\r	Carriage return
\t	Tab
\\	Backslash
\"	Double quote
\'	Single quote
\0	Null character
\uXXXX	Unicode code point (4 hex digits)

No string interpolation

Jyro does not support string interpolation. Use the + operator for concatenation:

var greeting = "Hello, " + name     # Correct
# var greeting = "Hello, ${name}"   # INCORRECT - not supported

When either operand of + is a string, the other operand is automatically converted to its string representation.

Regex pattern escaping

Jyro’s string lexer only recognises the escape sequences listed above. Any other backslash sequence - including regex metacharacters like \d, \w, and \s - causes a parse error. Use character classes instead:

Instead of	Use
\d	[0-9]
\w	[a-zA-Z0-9_]
\s	[ \t\n\r]
\.	[.]

# INCORRECT - parse error: \d is not a recognised escape sequence
var num = RegexMatch(text, "\d+")

# CORRECT - character class reaches the regex engine intact
var num = RegexMatch(text, "[0-9]+")
