Importing a mix of types and values in an import using a custom path results in undefined imports in result JavaScript

[shimmerjs]

Given:

file1.ts:

export type Foo = 'bar';

export const baz = 'inga'; // ;)

file2.ts:

import { Foo, baz } from '@custom/scope/file1';

[...]

When the code is compiled, the Javascript import will read something like this:

file2.js:

import { Foo, baz } from '@custom/scope/file1';

but Foo will be undefined and cause errors.

Thank you for the bug report, good spot.

Hi @booninite, I've made a PR #53 that should fix this issue, I'll probably merge it and publish it to npm later today.
It seemed to be an issue with the latest versions of typescript, could you confirm this fix it for you?

@all-contributors add @booninite for bug.

@danielpza I wasn't able to pick up the fix today, I should be able to try it out tomorrow and can let you know 👍

It doesn't seem to be working when I try it. Sample output & configuration is below:

marcel@marcel ~/tmp $ cat tsconfig.json 
{
	"compilerOptions": {
		"target": "esnext",
		"lib": [ "esnext" ],

		"baseUrl": ".",
		"paths": {
			"~/*": [ "*" ]
		},

		"plugins": [{ "transform": "typescript-transform-paths" }]
	}
}

marcel@marcel ~/tmp $ cat index.ts 
import { Format, value } from '~/format';
console.log(value);

marcel@marcel ~/tmp $ cat format.ts 
export type Format = number;
export const value = 1;

marcel@marcel ~/tmp $ npx ttsc
marcel@marcel ~/tmp $ cat index.js 
import { Format, value } from "./format";
console.log(value);

marcel@marcel ~/tmp $ cat package.json 
{
  "name": "tmp",
  "dependencies": {
    "ttypescript": "^1.5.10",
    "typescript": "^3.8.3",
    "typescript-transform-paths": "file:../code/typescript-transform-paths"
  }
}

marcel@marcel ~/tmp $ cd ../code/typescript-transform-paths/

marcel@marcel ~/code/typescript-transform-paths $ git rev-parse HEAD

Unfortunately PR #53 doesn't help, still the same effect.

Here is a with minimal code which reproduces the issue: https://github.com/DmitryKoterov/typescript-transform-paths-bug - could you please take a look?

Those excess import symbols don't allow to use es6 modules since node complains on an attempt to import an undefined symbol:
