V3 doesn't rewrite imports

[mikearnaldi]

when upgrading to v3 in https://github.com/Effect-TS/core I noticed modules are no longer replaced, we use typescript-transform-paths for our test suite and all the tests were failing for "module not found".

debugging manually shows the following:

V3:

V2:

A quick repro can be done by cloning the repo in question using a tsconfig like:

{
  "extends": "./tsconfig.json",
  "files": [],
  "compilerOptions": {
    "target": "ES2018",
    "module": "CommonJS",
    "plugins": [{ "transform": "typescript-transform-paths" }],
    "outDir": "debug"
  },
  "include": ["scripts/jest-setup-after-env.ts"]
}

when used with v2 the import @effect-ts/system/Structural of scripts/jest-setup-after-env.ts is replaced with v3 is left untouched

Interesting! Having a look into this now. Thanks for including repro detail.

So this is related to a breaking change in the matchPatternOrExact function. More specifically, it looks like they added caching to the paths pattern parsing to speed things up. This only effects dev builds.

Relevant commit: microsoft/TypeScript@3ffa245

I'm hesitant to fix this now, as these changes are not in an official release yet — moving parts and all. But, I see that it's affecting several of you, so I will integrate what's there. Please keep an eye on it, and let me know if things break again.

Update: Fix integrated into v3.0.1
