Breaks class definitions

[m-kostrzewa]

I was experimenting with the beautifier on existing codebase, and it seems to break class definitions. Here's an example:

Input

class TestClass {
  [string] $aa
}

$inst = [TestClass]::new()

Used command

> Edit-DTWBeautifyScript ./test.ps1  -Verbose                                             
VERBOSE: Reading source: .../test.ps1
VERBOSE: Tokenizing script content
VERBOSE: Migrate source content to destination format
VERBOSE: Write destination file: .../test.ps1
VERBOSE: Finished in 0.149 seconds.

Expected output

class TestClass {
    [string]$aa
}

$inst = [testclass]::new()

Actual output

class [testclass]{
  [string]$aa
}

$inst = [testclass]::new()

Of course, our test script breaks:

./test.ps1                                                                              
At .../test.ps1:1 char:6
+ class [testclass]{
+      ~
Missing name after class keyword.
+ CategoryInfo          : ParserError: (:) [], ParseException
+ FullyQualifiedErrorId : MissingNameAfterKeyword

This https://github.com/DTW-DanWard/PowerShell-Beautifier/blob/master/src/DTW.PS.Beautifier.Main.psm1#L910 seems like a candidate for the source of the issue, but I don't know the codebase.
