auto-import for `std` modules

@scarf005 It looked like #1069 was about exported symbols. Were you talking about files? This is already implemented: you need to add the following to your vscode settings:

{
  "deno.suggest.imports.hosts": {
    "https://deno.land": true
  }
}

jsr:@std/... supports this without configuration.

I was referring to symbols.

e.g I have to explicitly 'cache' https://deno.land/std/collections/map_values.ts to be able to import mapValues from there.

This is already implemented: you need to add the following to your vscode settings:

this doesn't work; i've already added the settings, yet in above screenshot it wouldn't suggest importing https://deno.land/std/collections/map_values.ts or https://deno.land/std/collections/mod.ts to be able to use mapValues.

Okay I understand, the apiland link was a response to the last thing I said in #1069 (comment).

We can add a setting to preload select remote libs into the ts server so their auto-imports are always available. However, at this point we would only do that for jsr or npm specifiers. With these in Deno, it's no longer worth developing package sniffing infrastructure for arbitrary or favoured https URLs. e.g.:

{
  "deno.preloadPackages": [
    "jsr:@std/path", // Preload all exports in `jsr:@std/[email protected]`.
    "jsr:@std/fs/.", // Preload only the default export in `jsr:@std/[email protected]`.
    "jsr:@std/fs/expand-glob", // Preload only the `expand-glob` export in `jsr:@std/[email protected]`.
    "npm:preact" // Preload whatever paths and exports are included in the type declarations for `npm:[email protected]`.
  ]
}

i disagree.

1. jsr: or npm: specifiers cause vendor lock-in (namely, deno). only URLs are free of vendor lock-in.
2. there's already existing package sniffing infrastructure (apiland), so it makes more sense to provide preloadPackages for http than jsr.
