Case transforming macros
Casey transforms the case of given input ident
s.
Niche but maybe useful in other macros.
use casey::{pascal, lower, shouty, snake, upper};
lower!(ABC); // renders: `abc`
upper!(abc); // `ABC`
snake!(ABC); // `a_b_c`
pascal!(ab_c); // `AbC`
shouty!(a_b_c); // `A_B_C`
Casey macros can operate on TokenStream
s e.g.
snake!(
#[derive(PartialEq)]
struct MockStruct {}
impl MockStruct {
fn test() -> bool { true }
}
);
assert!(mock_struct::test());
assert!(mock_struct::test() == mock_struct::test())
All ident
tokens in the stream will have the case transformation applied (keywords and attribute macros will be ignored).
Type names, including built-in types are not considered keywords e.g. bool
, usize
, i32
etc. and will be transformed by casey.
pascal!(let test: bool = true); // renders: `let Test: Bool = true;`
