Code with dictionary parse error breaks formatter

[NicholasBolen]

I have the following sample code which includes a parse error:

extends Control

# Error at (4, 6): Expected end of statement after variable declaration, found "{" instead.
var a: { "foo": "bar" } # Should be `a = {}`

# Ready function
func _ready() -> void:
	var prefix: String = "Value: "
	var count := 10

	for i in range(count):
		print(prefix, i)

Running the formatter gives the following result, unindenting all functions within the file:

extends Control

# Error at (4, 6): Expected end of statement after variable declaration, found "{" instead.
var a: { "foo": "bar" } # Should be `a = {}`

# Ready function
func _ready() -> void:
	var prefix: String = "Value: "
var count := 10

for i in range(count):
	print(prefix, i)

Formatter should probably not be able to run on a script containing parse errors to prevent this. Likely difficult to verify without godot running so this might be tricky.

The formatter actually does check for parse errors and tries to format only branches of the AST that do not have an error. But after testing, here I see the problem is that the parser does not plain stop processing your code when it encounters errors. It continues parsing the best it can until the end of the file, but with the dictionary error it eats up the start of the function definition before recovering and parsing normally.

I'll change it so that any error aborts formatting in the next update.
