Overview

This tool fixes Delphi's (RAD Studio XE4) formatter. In code like this:

const
  Pi = 3.000;

// CircleArea calculates the wrong area, since it eats the wrong pie.
function CircleArea(R: Single): Single;
begin
  Result := R * R * Pi;
end;

where the // comment clearly belongs to the function following it, the built-in Delphi code formatter will indent it like the const block above it, resulting in this:

const
  Pi = 3.000;

  // CircleArea calculates the wrong area, since it eats the wrong pie.
function CircleArea(R: Single): Single;
begin
  Result := R * R * Pi;
end;

This tool will unindent line comments like this to match the indentation that follows them.

CAVEAT: currently this tool only fixes // style line comments, not {} or (**) comments.

Additionally it changes this code:

var
X := Default (SomeType);
for I := low(X) to high(X) do
  setlength(Y, length(Y) + 1);

to this:

var X := Default(SomeType);
for I := Low(X) to High(X) do
  SetLength(Y, Length(Y) + 1);
