concat-symbols

Concatenates zero or more symbols into a new symbol.

(concat-symbols sym1 sym2 …) -> symbol?

• sym1 : symbol? — the first symbol to append
• sym2 : symbol? — the next symbol to append, and so on

Examples

> (concat-symbols 'he 'llo)
=> 'hello
> (concat-symbols)
=> '

symbol->string

Converts a symbol or quoted list into its string representation.

(symbol->string sym) -> string?

• sym : symbol? | list? — a symbol or quoted list to convert

Examples

> (symbol->string 'foo)
"foo"

> (symbol->string '(a b c))
"(a b c)"

> (symbol->string 123)
Error: symbol->string expected a symbol, found 123

symbol=?

Compares one or more symbols for pointer‐identity equality.

(symbol=? sym1 sym2 …) -> bool?

• sym1 : symbol? — the first symbol to compare
• sym2 : symbol? — the next symbol to compare, and so on

Returns #t if all provided symbols share the same memory pointer, #f otherwise. At least one argument is required.

Examples

> (define a 'foo)
> (define b 'foo)
> (symbol=? a b)
=> #t
> (symbol=? 'a 'b)
=> #f
> (symbol=? 'x 'x 'x)
=> #t
