Strings

Status: implemented

Both quote styles accept JSON escapes and braced Unicode escapes (\u{…}). A single-quoted string also accepts an escaped apostrophe, \xHH and \v:

export default ["hello!", 'hello!'];

The escapes, the quotes and where a string may stand are specified in string escapes and quotes.

Examples

The compiler demo has no programs for this page yet: its accepted and refused examples are a follow-up.

The demo on this page runs sample.f.js, this page's example as a function of one number — strings in double quotes and in single quotes — with every output fjs compile makes of it: the expression graph (EDAG), the Rust and the WebAssembly that Rust builds to. Its Run button calls the default export with 0 and 1, as JavaScript and as WebAssembly, and shows what each call returned or threw.

export default (...a) => ["hello!", 'hi!'][Number(a[0])].length;

Reference

Demo

In FunctionalScript

fjs compile accepts this module, and it runs as JavaScript and as WebAssembly alike.

A FunctionalScript module and what fjs compile makes of it: the expression graph it lowers to, the Rust it compiles to on the NaNVM runtime, and the WebAssembly that Rust builds to. Run calls its default export with 0, then 1, first as the JavaScript it already is and then as WebAssembly, and shows what each call returned or threw and how long one call takes, timed over 1000 calls.

FunctionalScript source:

/**
 * The example of [`README.md`](./README.md) (Strings) as a function of one
 * number, for the page's WASM demo: strings in double quotes and in single
 * quotes.
 *
 * @module
 */

/** @type {(...a: readonly number[]) => unknown} */
export default (...a) => ["hello!", 'hi!'][Number(a[0])].length;

Expression graph (EDAG) that fjs compile lowers it to:

=>lengthbody0..objkey."length".objidx[]01"hello!""hi!"Numberoperand.objidxrest0

The same graph, as fjs compile writes it to a .edag.data.js file:

export default ["{}",[[":","default",["=>",0,[],[".",[".",["[]",["hello!","hi!"]],["Number",[".",["rest"],0]]],"length"]]]]];

Rust that fjs compile writes from it, on the NaNVM runtime:

// @generated by `fjs compile`. Do not edit: recompile the source module instead.

use nanvm_lib::vm::unstable::{f64_any, string_any, string_key};
use nanvm_lib::vm::{Any, Array, IStaticFunction, ToAny, ToArray, ToObject};

#[rustfmt::skip]
#[allow(clippy::if_same_then_else)]
pub fn module<A: IStaticFunction>(_runtime: Any<A>) -> Result<Any<A>, Any<A>> {
    Ok([(string_key("default"), A::static_function(|_self, _args| {
        let _b264: Any<A> = _args.rest(0).to_any();
        Any::dot((Any::dot([string_any("hello!"), string_any("hi!")].to_array().to_any(), (Any::number((Any::dot(_b264.clone(), f64_any(0x0000000000000000)).end())?))?).end())?, string_any("length")).end()
    }, 0, Array::default(), Some("(...$0)=>[\"hello!\",\"hi!\"][Number($0[0])].length")).to_any())].to_object().to_any())
}
