VS Code does not treat typescript dot files the way TSC command treats them

• VSCode Version: 1.22.2
• OS Version: Arch Linux

Steps to Reproduce

1. Create tsconfig.json

{
  "compilerOptions": {
     "target": "es2017",
     "module": "commonjs",
     "lib": ["es2017"]
  }
}

2. Create 2 files: .dotfile.ts (begin with a dot) and normalfile.ts

Object.entries({})

Expected behavior

There should be no problem

Actual behavior

In .dotfile.ts, linter marks entries word with message [ts] Property 'entries' does not exist on type 'ObjectConstructor'.

Things are okay in normalfile.ts

Yes this is by-design. In most cases you do not want dot files included in a project.

To explicitly include dot files, try setting:

{
    "compilerOptions": {
        "target": "es2017",
        "module": "commonjs",
        "lib": [
            "es2017"
        ]
    },
    "exclude": [
        "node_modules"
    ],
    "include": [
        "**/*.ts",
        "**/.*.ts"
    ]
}

@mjbvz Still, there's inconsistency: tsc cli treats them differently (allowing them). I wouldn't complain if its behavior was consistent. My point is VS Code should only tell user what tsc cli would tell.

@mhegazy Thoughts on @KSXGitHub's point about tsc and tsserver handling dot files differently?

not sure i follow what you mean by tsc allows them.. tsc does not pick up files starting with dots either unless you explicitly specify them in your tsconfig.json.. e.g.:

c:\test\23750>tree /F .
C:\TEST\23750
    .b.ts
    a.ts
    tsconfig-noInclude.json
    tsconfig-withInclude.json

c:\test\23750>type tsconfig-noInclude.json
{
    "compilerOptions": {
        "target": "es5"
    }
}

c:\test\23750>type tsconfig-withInclude.json
{
    "compilerOptions": {
        "target": "es5"
    },
    "include": [
        "**/*.ts",
        "**/.*.ts"
    ]
}

c:\test\23750>tsc --v
Version 2.8.3

c:\test\23750>tsc --p tsconfig-noInclude.json --listFiles
C:/Users/mhegazy/AppData/Roaming/npm/node_modules/typescript/lib/lib.d.ts
c:/test/23750/a.ts

c:\test\23750>tsc --p tsconfig-withInclude.json --listFiles
C:/Users/mhegazy/AppData/Roaming/npm/node_modules/typescript/lib/lib.d.ts
c:/test/23750/a.ts
c:/test/23750/.b.ts

OK, I double-checked, tsc ignores dot files. My bad. Sorry for that. This issue can be closed now.
