Vscode: Disable validation of specific typescript files

[msqaddura]

Issue Type: Bug

Tested on this repo:
https://github.com/itslenny/scaffs
These files:
https://github.com/itslenny/scaffs/tree/master/test/data/scaffolds/Example

Knowing that:
1) the scaffold files have to be *.ts so changing file extension wont help

Expected Result:
after putting in settings.json "files.watcherExclude" to exclude this folder and also in tsconfig.json "exclude" the folder, VSCode's Problem Viewer should not show [ts] errors.

Real Result:
VSCode shows that these files are erronous

settings.json (please note, i tried so many variances until landed ignore whole folder)

tsconfig.json (as well added the whole folder)

errors (though VSCode should not look into them)

VS Code version: Code 1.30.0 (c6e592b2b5770e40a98cb9c2715a8ef89aec3d74, 2018-12-11T22:21:33.585Z)

I think this is related to ts, not the watcher

[msqaddura]

yes it does seem so, yet isnt it supposed at least via tsconfig>exclude to understand that this file is not to be validated? and actually linting errors disappeared after i excluded the files in tslint.config.json so there must be a charm somewhere. Otherwise, how could I solve this one problem?

Yes, vscode's exclude settings are not related to typescript validation. And the tsconfig exclude setting configures the TypeScript project, it will also not disable validation for TS files you open

A few options:

• Disable all TS validation by setting "typescript.validate.enable": false

• Get TS to support a @no-check flag in files: https://github.com/Microsoft/TypeScript/issues/26887

• Use file associations to tell VS Code not to treat these files as TS (we won't parse these template files or even colorize them correctly anyways)

  For this, try setting:

  "files.associations": {
      "**/path/to/templates/**/*.ts": "plaintext"
  }
