Various Formatter Improvements

[DaelonSuzuka]

This introduces a new syntax for defining snapshot tests, and fixes at least #717, #734, #728.

Snapshot tests can now be defined in a single file using "blocks":

# --- IN ---
var  a  =   10
# --- OUT ---
var a = 10

I also FINALLY found a solution to remove leading empty newlines from blocks:

# --- IN ---
func test():

	pass
# --- OUT ---
func test():
	pass

# --- IN ---
class Test:

	func _ready():

		pass
# --- OUT ---
class Test:
	func _ready():
		pass

Breaks on lines in a multiline string:

func dump() -> String:
	return """
	{
		level_file: '%s',
		md5_hash: %s,
		text: '%s',
		level_size: %s,
		world_pos: %s,
		preview_size: %s,
		preview_pos: %s,
		preview_texture: %s,
		explorer_layer: %s,
		connections: %s,
	}
	""" % [level_file, md5_hash, text, level_size, world_pos, preview_size, preview_pos, preview_texture, explorer_layer, connections]

👇

func dump() -> String:
	return """
	{
		level_file: '%s',
		md5_hash:%s,
		text: '%s',
		level_size:%s,
		world_pos:%s,
		preview_size:%s,
		preview_pos:%s,
		preview_texture:%s,
		explorer_layer:%s,
		connections:%s,
	}
	""" % [level_file, md5_hash, text, level_size, world_pos, preview_size, preview_pos, preview_texture, explorer_layer, connections]

Thanks @limbonaut! That one's fixed now.

An issue with quotes and unique name specifier:

@onready var main_menu: Button = %"Main Menu"

👇

@onready var main_menu: Button = % "Main Menu"

[limbonaut]

That's all I found. Nice to see the old issues fixed, and it's shaping up to be a really solid formatter.

Imaginary number with j suffix? Are complex numbers supported syntax in GDScript now?
Is there a source proposal/docs or something?

[DaelonSuzuka]

Nope, I copied it from MagicPython and didn't notice the j's! Thanks for the catch.

You probably want to double-check by testing whether it supports, e.g. lower and uppercase e, E and f, F suffix (I don't think there's a LF suffix, as its float is always a double). Also whether it supports _ separators and . cases like 0. or .5. Float literals syntax can vary a lot depending on the language, e.g. GDShader (or whatever it's going to be called) technically accepts even weird cases like 0.f IIRC.
