Changes
- Removed
AsRest marker, and instead made repetitions more flexible - you can now provide an array of array literals to any repetition, to make it repeat over all of the literals:
function $showcase(a: Array<string>, b: Array<number>, c: { values: [Array<number>] }) {
+["+", [a, b, c.values[0]], (number: number|string) => number];
}
console.log($showcase!(["a", "b", "c", "d"], [1, 2, 3], { values: [[1, 2, 3]]}))
// Turns to:
console.log("abcd123123");
- Removed the
$$import built-in macro.
- Removed
, from the repetition separators and replaced it with () (comma list expression)
- Errors coming from the transformer are now formatted like regular typescript diagnostics are.
Additions
- Added a
$$ts built-in macro which turns strings into typescript code.
- Added an
$$escape built-in macro which puts code inside the parent scope if necessary:
function $test(arg: string) {
$$escape!(() => {
console.log("Instead of this macro expanding to an IIFE, it will expand to the returned value.");
});
return arg + "456";
}
(() => {
const array = $test!("123");
})();
// Transpiles to:
(() => {
console.log("Instead of this macro expanding to an IIFE, it will expand to the returned value.");
const array = "123456";
})();
- Added a
$$includes built-in macro which checks if a value is included in an array / string literal.
- Added a
$$slice built-in macro which slices an array / string literal.
- Added a
$$typeToString built-in macro which turns any type to a string literal.
- Added a
$$propsOfType built-in macro which expands to an array literal containing all the property names of a type.
- Added a
Save marker, which always saves the provided expression in a variable with a unique name.
- Almost every binary and unary operation can now be computed at transpile-time.
- Macro function declarations now act more like regular functions - you can re-define macro functions in different blocks:
export function $map() {
return 1;
}
function test() {
function $map(msg: string) {
return msg + " World!";
}
$map!("Hello");
}
$map!();
// Turns to:
function test() {
return "Hello World!";
}
1;
