Hydrate a REPL with new globals from a file's exports.
Given a file at path/to/file.js containing the following:
``js`
export const foo = () => { console.log('FOO') }
Running the following command will open a custom REPL:
`sh`
hrepl path/to/file.js --some args
Typing foo() and hitting return in the REPL will result in theFOO!
output of
``sh`
> foo()
FOO!
The process.argv array will look as if the file has been run directly with Node.
In the example case, process.argv will be [
The repl includes a .log command for async (or sync) iteration:
``sh`
> async function * f () { yield 1; yield 2; yield 3 }
> o = f()
Object [AsyncGenerator] {}
> .log o
try { for await (const data of o) console.log(data) } catch { console.log(o) }

> .log [1,2,3]
try { for await (const data of [1,2,3]) console.log(data) } catch { console.log([1, 2, 3]) }
