0.29.0

Breaking Changes

The formatting command will now exit with an error code of 1 if one of the target files cannot be compiled #1131

Prior to 0.29.0 if csharpier encountered a file that could not be compiled it would treat it as a warning and exit with a code of 0.
As of 0.29.0 a file that cannot be compiled is now treated as an error and csharpier will exit with code 1

What's Changed

Enforce trailing commas in object and collection initializer #668

CSharpier will now add trailing commas automatically where appropriate. It will collapse to a single line and remove the trailing comma in cases where everything fits on one line.

// input
public enum SomeEnum
{
    Value1,
    Value2
}

string[] someArray = new string[]
{
    someLongValue_____________________________________________,
    someLongValue_____________________________________________
};

string[] someArray = new string[]
{
    someValue,
    someValue,
};

// 0.29.0
public enum SomeEnum
{
    Value1,
    Value2,
}

string[] someArray = new string[]
{
    someLongValue_____________________________________________,
    someLongValue_____________________________________________,
}

string[] someArray = new string[] { someValue, someValue };

Many thanks go to @dawust for the contribution.

Support for formatting custom file extensions #1220

Prior to 0.29.0 csharpier would only format files with an extension of .cs or .csx. It is now possible to configure csharpier to format other files extensions, and to specify configuration options per file extension.
See https://csharpier.com/docs/Configuration#configuration-overrides for more details.

Invalid blank line being added with lambda returning collection expression #1306

// input & expected output
CallMethod(_ =>
    [
        LongValue________________________________________________,
        LongValue________________________________________________,
    ]
);

// 0.28.2
CallMethod(_ =>

    [
        LongValue________________________________________________,
        LongValue________________________________________________,
    ]
);

Switch expressions do not break consistently with other lambdas #1282

Prior to 0.29.0 csharpier would break before the => in switch expression arms. It now breaks after them to be consistent with other lambda expressions.

// 0.28.2
return someEnum switch
{
    Value1 => someOtherValue,
    Value2
    or Value3
        => someValue________________________________________________________________________,
    Value4
        => someValue_____________________________________________________________________________,
};

// 0.29.0
return someEnum switch
{
    Value1 => someOtherValue,
    Value2 or Value3 =>
        someValue________________________________________________________________________,
    Value4 =>
        someValue_____________________________________________________________________________,
};

Formatting of empty collection initializer for huge type #1268

Empty collection expression initializers formatting was including a break plus indentation resulting in poor formatting.

// 0.28.2
var someObject = new List<(
    int Field1__________________________________,
    int Field2__________________________________
)>
{
    };

// 0.29.0
var someObject = new List<(
    int Field1__________________________________,
    int Field2__________________________________
)>
{ };

Switch expression single line broken when preceded by comment #1262

Improved formatting for short expression arms that have a leading comment.

// 0.28.2
return someValue switch
{
    // comment
    Some.One
        => 1,
    Some.Two => 2,
};

return someValue switch
{
    Some.One => 1,
    // comment
    Some.Two
        => 2,
};

// 0.29.0
return someValue switch
{
    // comment
    Some.One => 1,
    Some.Two => 2,
};

return someValue switch
{
    Some.One => 1,
    // comment
    Some.Two => 2,
};

Incorrect formatting of ternary expression with a comment after an interpolated string #1258

Fixed bug with comments on a ternary expression that resulted in invalid code.

// input & expected output
public string TrailingComment = someCondition
    ? $"empty" // trailing comment
    : someString;

// 0.28.2
public string TrailingComment = someCondition ? $"empty" // trailing comment : someString;

Formatting for indexer parameters should mostly be the same as for method parameters. #1255

Improved formatting of indexed properties that contained attributes.

// input & expected output
public class ClassName
{
    public string this[
        [SomeAttribute] int a________________________________,
        [SomeAttribute] int b________________________________
    ] => someValue;
}

// 0.28.2
public class ClassName
{
    public string this[[SomeAttribute] int a________________________________, [SomeAttribute]
        int b________________________________] => someValue;
}

Do not overwrite CSharpier_Check when already set. #1314

Fixed a bug with csharpier.msbuild where it would overwrite the CSharpier_Check value in some cases.

The CLI has contradictory message about directoryOrFile being required #1296

The help text for the cli has been improved to better indicate when directoryOrFile is required.

Fullwidth unicode characters should be accounted for in print width #260

CSharpier now considers full width unicode characters such as 가 to be 2 spaces wide when determining how to format code.
