CSharpFixFormat for Visual Studio Code

This extension helps to format C# code. When OmniSharp will support all features - will be deprecated.

C#5 / C#6 / C#7 support limited and some features not implemented, because main goal of this extension - formatting C#3.5 / C#4 sources of UnityEngine projects on MacOS, nothing more.

If you need full format support of last C# version - better to write issue about proper formatting at Omnisharp extension repo.

Dependencies

This extension not dependent on any 3dparty extensions (even omnisharp) and works as standalone formatting solution for current C#-file.

Features

All features available through standard "format document" hotkey after opening C# file.

Sort usings in alphabetical order. Doubles will be removed automatically.
Fix indent size for all lines (omnisharp still cant do it for wrapped lines).
Cleanup empty lines with allowed limit in row.

Extension provides formatting in batch mode through folder context menu at explorer window.

Special flags

Formatting can be ignored for any code with wrapping to directives:

/* fixformat ignore:start */
var test    =        i().  willNotBeFormatted     []   ;
/* fixformat ignore:end */

Known issues

Multilined constrained generics not supported:

class<T>
    where T : class
{
}

Suggestion - put constraints on one line:

class<T> where T : class
{
}

Multiline initialization for new instance as parameter for method will not be formatted correctly:

TestMethod (new TestClass {
    a = 10,
        b = 20
});

Suggestion - split variable declaration and method calling:

var t = new TestClass {
    a = 10,
    b = 20
};
TestMethod (t);

Initialization with nested "{ }" can be formatted wrong:

Expected:

new System.Collections.Generic.Dictionary<string, string>() {
    { "", "" },
    { "", "" },
    { "", "" },
};

Actual:

new System.Collections.Generic.Dictionary<string, string>()	{
    { "", "" }, { "", "" }, { "", "" },
};

Suggestion - add comment for each item in initialization:

new System.Collections.Generic.Dictionary<string, string>() {
    // Item 1 description.
    { "", "" },
    // Item 2 description.
    { "", "" },
    // Item 3 description.
    { "", "" },
};
