Deno imports no longer working in v 1.4

[andrewpbray]

Description

I just upgraded quarto v1.3 to quarto 1.4 and I'm now getting an error when trying to run a .ts script.

(base) MacBookPro:deno-reprex andrewbray$ quarto run test-script.ts
error: Specifier not found in cache: "https://deno.land/[email protected]/encoding/yaml.ts", --cached-only is specified.
    at file:///Users/andrewbray/Desktop/deno-reprex/test-script.ts:1:23

This is in a minimal repo that is the boilerplate website plus a test-script.ts file containing:

import { parse } from "https://deno.land/std/encoding/yaml.ts";

const config = parse(Deno.readTextFileSync("_quarto.yml"));

Which is the example taken from the quarto docs.

Version info:

(base) MacBookPro:deno-reprex andrewbray$ quarto --version
1.4.549

@andrewpbray: Oh, actually we did do it. The issue is that deno changed their stdlib in a way that we can't actually paper over.

You need to import from a different path, unfortunately:

import { parse } from "https://deno.land/std/yaml/mod.ts";

We don't document these changes because we don't actually know it ourselves. As far as I can tell, there's no change log in deno's stdlib that describes the path or API changes :(

Ah, ok, makes sense.

I've put in a PR to update the docs:

quarto-dev/quarto-web#996

🤦 Thank you!

(@dragonstyle, @cwickham: this is just a note to highlight this general class of problem we have with docs, where the docs don't include testing that ensures that the docs are correct. I don't know what our solution should be precisely. But the fact that Quarto documentation, of all pieces of software, is prone to this, I think is salient.)
