has anyone used closure library (not compiler) in a cherry app? in cljs mindset i’m so used to requiring goog.whatever stuff, which doesn’t work. so far, looking at the npm instructions which say to do the following:
require("google-closure-library");
goog.require("goog.crypt.Sha1");
var sha1 = new goog.crypt.Sha1();
sha1.update("foobar");
var hash = sha1.digest();(ns foo
(:require ["google-closure-library" :as goog]))
(js/console.log goog["require"])$ npx cherry run foo.cljs

meta: null,

shift: 5,
root: ei {

},

I noticed the bug you were encountering with $default also happened here (see error in console):
https://squint-cljs.github.io/cherry/
I now have a repro :)

Neat! Sorry I didn’t get the bug filed yet — I started down the rabbit hole of trying to simplify from the closure library and realized that library is too much of a black box with its requires for me to do without reading that dang book, which I suppose is the ultimate yak shave
borkdude 2023-05-13T13:36:17.758239Z
no problem
borkdude 2023-05-13T19:00:06.841139Z
@wcohen The $default thing should now work as expected in 0.0.3
borkdude 2023-05-06T19:12:45.691679Z
It looks as if what gets logged is a CLJS data structure
borkdude 2023-05-06T19:13:44.958259Z
could be wrong. could you try
(ns foo
(:require ["google-closure-library$default" :as goog]))borkdude 2023-05-06T19:13:52.972259Z
so try the $default
wcohen 2023-05-06T19:17:42.447729Z
that results in:
import * as goog from 'google-closure-library';
^^^^^^^^^^^^^^^^
SyntaxError: Identifier 'goog' has already been declaredwcohen 2023-05-06T19:18:11.901379Z
ah — trying $require
borkdude 2023-05-06T19:19:32.140929Z
that won't work. can you try goog.default.require?
wcohen 2023-05-06T19:22:10.566839Z
goog.default doesn’t exist.
goog["default"] gives a global object with lots of junk that includes require:
[cherry] Running resource.cljs
<ref *2> {
global: <ref *1> Object [global] {
global: [Circular *1],
queueMicrotask: [Function: queueMicrotask],
clearImmediate: [Function: clearImmediate],
setImmediate: [Function: setImmediate] {
[Symbol(nodejs.util.promisify.custom)]: [Getter]
...wcohen 2023-05-06T19:22:56.317119Z
i think that’s it — (.-require goog["default"])
borkdude 2023-05-06T19:23:22.999089Z
yes, but goog["default"] or goog.default or goog/default should be the same thing
wcohen 2023-05-06T19:24:13.487219Z
that’s what i assumed too! but only the one works
wcohen 2023-05-06T19:24:29.437979Z
the others are undefined
borkdude 2023-05-06T19:37:20.033119Z
I think that might be a bug in cherry then
borkdude 2023-05-06T19:37:28.043199Z
welcome to post an issue about it
wcohen 2023-05-06T19:37:32.761429Z
will do!
wcohen 2023-05-06T19:41:10.758679Z
either way — once I get to (.-require goog[“default”]), that yields a [Function [anonymous]] — if this were a situation where google closure library weren’t totally nuts nominally i could invoke it with something like ((.-require goog["default"]) a b c )?
borkdude 2023-05-06T19:42:58.036219Z
Yeah, you can do:
(def goog-require (.-require goog["default"]))(goog-require a b c)wcohen 2023-05-06T19:11:06.617739Z
it seems like if I can just figure out how to run this require function the rest should proceed just fine
