A string from the standard input is incorrectly compared with another

[comminux]

Godot version

System information

Arch Linux x86_64

Issue description

The following condition will never be true, even if the user enters the value of another string correctly.

func _process(delta):
	print(OS.read_string_from_stdin() == "test")

Steps to reproduce

1. Export the minimal reproduction project in zip or pack file.
2. "godot --main-pack stdin-exported.zip"
3. Enter the word "test" into the console and press enter.

Minimal reproduction project

Have you tried if it matches "test\n"?

[comminux]

"test\n" is also not true

[AThousandShips]

Can confirm that it does include a linebreak, and the actual line is "test\r\n", at least on Windows, you need to strip the newlines

Would need to be documented or discussed, exactly how it works

[comminux]

I read the description of the pull request for this method and figured out my problem. You need to use OS.read_string_from_stdin().strip_edges() and then string comparison will be correct.

I think it will be enough to leave a mention in the documentation for the strip_edges method for OS.read_string_from_stdin()

[AThousandShips]

As I was saying, you didn't need to figure it out yourself 🙃

[comminux]

After Godot 4.4 dev 5 stdin handling will work via OS.read_string_from_stdin(1024).strip_edges()

In the end we assessed that it's a bug, and #99542 will fix it.
