sexpr!() { /* proc-macro */ }Expand description
Parse a string of a single s-expression into a kamo::value::Value.
The syntax is defined by the Scheme standard R7RS for the read procedure.
For the deviations from the standard see the documentation of the macros
crate.
The macro takes an optional MutatorRef identifier. This is used to
allocate values on the heap. If the expression does not contain any values
that need to be allocated on the heap, then the Mutator identifier can be
omitted.
The syntax is sexpr!(<mutator>, <expression>).
§Examples
ⓘ
use kamo::{mem::Mutator, sexpr, value::{print, Value}};
let m = Mutator::new_ref();
let value = sexpr!(m, "(1 2 3)");
assert_eq!(print(value).to_string(), "(1 2 3)");
