CSharpier 0.10.0

CSharpier

CSharpier is an opinionated code formatter for c#. It uses Roslyn to parse your code and re-prints it using its own rules. The printing process was ported from prettier but has evolved over time.
CSharpier provides a few basic options that affect formatting and has no plans to add more. It follows the Option Philosophy of prettier.

Work In Progress

CSharpier is still in active development and the rules it uses to format code are not yet finalized and will change over time.

If you can live with the fact that the formatting will be changing over time, it is safe to use. In addition to a steadily growing set of unit tests; csharpier is tested against ~60k c# files from a range of public repositories to validate it does not result in the lose of any source code.

Features

• It is fast. It can format a solution of ~11,000 files in ~30 seconds.
• It supports validating the syntax of the code it produces to ensure the only changes made were whitespace and line breaks.
• It formats c# ⇐ 9.0 - c# 10 coming soon

Before

public class ClassName {
    public string ShortPropertyName {
        get;
        set; 
    }

    public void LongUglyMethod(string longParameter1, string longParameter2, string longParameter3) { 
        this.LongUglyMethod("1234567890", "abcdefghijklmnopqrstuvwxyz", "ABCDEFGHIJKLMNOPQRSTUVWXYZ");
    }
}

After

public class ClassName
{
    public string ShortPropertyName { get; set; }

    public void LongUglyMethod(
        string longParameter1,
        string longParameter2,
        string longParameter3
    )
    {
        this.LongUglyMethod(
            "1234567890",
            "abcdefghijklmnopqrstuvwxyz",
            "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
        );
    }
}
