unable to import from library (ascMain not working?)

[trusktr]

Code is here: lume/glas#111

asc v0.17.7

I believe ascMain is set up correctly, but it doesn't seem to work.

From that example, here is the aswebglue ascMain field pointing to src/WebGL.ts:

https://github.com/lume/ASWebGLue/blob/9499782e0d7b3b9f51bbe3c7238abf0838f51c71/package.json#L4

  "ascMain": "src/WebGL.ts",

Here is src/WebGL.ts which is located exactly where ascMain points to:

https://github.com/lume/ASWebGLue/blob/9499782e0d7b3b9f51bbe3c7238abf0838f51c71/src/WebGL.ts

Here is the file that tries to import stuff from 'aswebglue' but it doesn't work:

https://github.com/lume/glas/blob/8f56ae0bb0d5796d4202fbfab7a352e00bc44600/src/as/test.ts#L2

import {SHORT} from 'aswebglue'

Steps to reproduce:

git clone git@github.com:lume/ASWebGLue.git
cd ASWebGLue
git checkout assemblyscript-issue-1679
cd src/examples/CubeNodejs
npm install
npm start

That will output the following error:

❯ npm start

> @ prestart /home/trusktr/src/battlelinegames+ASWebGLue/src/examples/CubeNodejs
> npm run build


> @ build /home/trusktr/src/battlelinegames+ASWebGLue/src/examples/CubeNodejs
> asc cube.ts -b cube.wasm

I was able to reproduce the bug. I found a work around by explicitly declaring the relative path. Looks like its using the LIBRARY_PREFIX path regardless if its a defined as a USER source library by the parser.ts.

work around:

import {SHORT} from '../../node_modules/aswebglue/src/webgl'

When I follow the reproduction steps, I get a version of aswebglue in node_modules that has "ascMain": "webgl.ts",. Could this be a dependency problem?

Also, src/test.ts does not exist.

The commit hashes to use are above in the OP links.

lume/glas repo: 8f56ae0bb0d5796d4202fbfab7a352e00bc44600

aswebglue: 9499782e0d7b3b9f51bbe3c7238abf0838f51c71

If you checkout lume/glas to that hash, you can modify package.json to have the exact hash for the aswebglue dependency, but it should be reproducible even without doing that.

@dcodeIO simple reproduction:

git clone git@github.com:lume/ASWebGLue.git
cd ASWebGLue
git checkout assemblyscript-issue-1679
cd src/examples/CubeNodejs
npm install
npm start

You will see this output:

❯ npm start

> @ prestart /home/trusktr/src/battlelinegames+ASWebGLue/src/examples/CubeNodejs
> npm run build


> @ build /home/trusktr/src/battlelinegames+ASWebGLue/src/examples/CubeNodejs
> asc cube.ts -b cube.wasm

Updated the previous comment, the reproduction is reproducible and won't change.

Per @trusktr request, I was able to try to import using import {myExport} from 'my-npm-lib/some-folder-in-the-lib/some-file', and it didn't work for me either in my project:

(Also, as a quick note, I don't require this behavior for my library, just wanted to help @trusktr reporduce, since they had asked 😄 👍 )

[dcodeIO]

@trusktr For some reason the second repro also doesn't work on my machine. Can't install glfw-raub or something.

Btw, did you try if it works if you remove the /src/ from the import? I believe the root directory is dir(ascMain) essentially.

[trusktr]

@dcodeIO

Yeah, I tried all approaches. @torch2424 listed one approach (direct file post-fixed onto the library name). But it fails on more approaches:

// ascMain in some-lib is "src/index.js" which re-exports from "./path/to/direct/foo.ts"

import {foo} from 'some-lib' // error
import {foo} from 'some-lib/src/path/to/direct/foo.ts' // error

// With this one I expect it to read `ascMain` from package.json in the `some-lib/` folder,
// but I wouldn't be surprised if this particular case hasn't been implemented yet, as
// people most likely won't be trying this unless they are working around the original issue.
import {foo} from '../../../node_modules/some-lib' // error

// This one works:
import {foo} from '../../../node_modules/some-lib/src/path/to/direct/foo.ts' // good

I didn't try to remove src/, but my guess is it won't work either.

I'm in Linux. Maybe glfw-raub has an issue on another OS or flavor of Linux.

Let me see about making a reproduction with only one dependency.

ruab doesnt work on my windows or linux machines either.

Got the same error... :(

Hey, @trusktr @torch2424 @ZoeDreams , it seems to be fixed!
