Formatter fails to format uglified files

[dbaeumer]

TypeScript Version: 1.8.10

I use vscode from the Command Palette to format a javascript file uglified by uglify-js, but it failed. It not format code correctly, and only format partially.

source file

sublime jsFormat formated

vscode formated

You see, It seems like, vscode only add some spaces around brackets, letters, commas etc.

See microsoft/vscode#8914 (comment) and the discussion below for more details. The provided traces clearly show that the tsserver only returns white space (" ") changes. No insertion of new lines.

The formatter favors keeping functions on the same line when the user specified. this is to suppport things like:

var o { p: function () { }, c: function () { } };

the result is for a minified file, you get one long line, with some spaces added, but no new lines.

I suppose we could add an option to add newlines always after {.

Not sure if #23829 is the same problem, but you'll notice in that report that there is no code highlighting happening either. Not having a setting that enables the same behavior as commonly available command line tools is very unfortunate. Is there any plan to provide this level of functionality, or an alternative approach available?
