Is there a way to make vscode line number field smaller width?

Question

The vertical column that contains the code line number is VSC is too wide. Is there a way to narrow it down?

Answer 1

[EDIT MAY 2020] The name of the undocumented setting has apparently been changed to editor.lineDecorationsWidth, so updating answer below.

Actually, there is an undocumented setting in Visual Studio Code that will do exactly what you want. It's called "editor.lineDecorationsWidth", and although you will get some kind of warning Unknown setting parameters or underline squiggly, it will work.

This is the config for minimum possible space taken by line numbers (and keeping said line numbers, of course):

"editor.lineDecorationsWidth": 0,
"editor.glyphMargin": false,
"editor.folding": false,
