TypeScript 3 project references: no navigation, no found references

[mjbvz]

_From @screendriver on August 14, 2018 10:20_

• VSCode Version: 1.26.0
• OS Version: macOS high sierra 10.13.6

Steps to Reproduce:

1. Create a new TypeScript project that uses the new project reference settings like in this repository
2. Try to navigate to a definition (F12) or find a references (shift + F12)
3. nothing happens and it can't find any references
4. I created a repository where you can reproduce the issue

Does this issue occur when all extensions are disabled?: Yes

Maybe it is related to this https://github.com/Microsoft/vscode/issues/55827 issue?

I'm not sure the project is configured correctly. Someone on the TS team will know more. When ruuningtsc at the root I see this error:

The 'files' list in config file '/Users/matb/projects/san/vscode-project-references-bug/tsconfig.json' is empty.

2   "files": [],
             ~~

By tweaking shared/tsconfig.json to:

{
  "extends": "../../tsconfig.settings.json",
  "compilerOptions": {
    "outDir": "../../dist/shared",
    "composite": true
  },
  "files": [
    "./logic.ts"
  ]
}

And compiling server/tsconfig , I do see things work under typescript@next. In TypeScript 3.0.1 however there are tooling failures:

Error: Debug Failure. Bad line number. Line: 2, lineStarts.length: 2 , line map is correct? true

@screendriver Please try upgrading your workspace to use typescript@next by following these instructions

I'm not sure the project is configured correctly. Someone on the TS team will know more. When ruuningtsc at the root I see this error:

Yes, that's because I use the new project references that comes with TypeScript 3. Just do a tsc --build and it works. That project is not meant to be build with tsc as before because project references works differently. With tsc --build the project builds as expected.

That was the reason why I opened the issue https://github.com/Microsoft/vscode/issues/56335 in the Visual Studio Code project because the navigation (Cmd + Click on a import) or finding references (Shift + F12) does not work there. So I believe this is not a tsc issue because this works correctly as expected.

[andy-ms]

This seems to be working for me with typescript@next with that repository after running tsc --build. Note that I did not run npm install, I used my globally installed typescript@next .

The fact that this fails on computePositionOfLineAndCharacter reminds me of #25844 which should only happen when declaration files are out-of-date, so maybe you can fix by running tsc --build again and restarting vscode?

[screendriver]

so maybe you can fix by running tsc --build again and restarting vscode?

This doesn't work. I already tried everything that I could imagine: disabling all extensions, restarting Visual Studio Code, remove and re-install Visual Studio Code...

[andy-ms]

• Are you building with typescript@next instead of [email protected]?
• Is vscode set up to use typescript@next?

I tried it out now. It works with typescript@next. Great 👍

[screendriver]

One question @andy-ms : today I saw a new release of TypeScript v3.0.3 With that bugfix it doesn't work. Could it be that @next already pointed to a newer version that will be released after 3.0.3?

[weswigham]

Yeah, 3.0.3 only has a small handful of backported bug fixes. Afaik we should be scheduled for a 3.1rc/release in the next two or three weeks.
