Autoload naming broken in 4.5

[Jesusemora]

Tested versions

• Reproducible in: Godot Engine v4.5.stable.official
• Not reproducible in: Godot v4.4.1

System information

Godot v4.5.stable - Ubuntu 22.04.5 LTS 22.04 on X11 - X11 display driver, Multi-window, 1 monitor - Vulkan (Forward+) - integrated AMD Radeon Vega 11 Graphics (RADV RAVEN) - AMD Ryzen 5 2400G with Radeon Vega Graphics (8 threads) - 5.71 GiB memory

Issue description

Autoloads are not given a class name in PascalCase.

in 4.4 and earlier versions, autoload script files would be written in snake_case, and automatically given a class name in PascalCase. now script files are no longer being renamed in autoload, leaving them in snake_case and forcing us to rename them, this causes both names to appear when typing until godot is restarted.

behaviour in 4.5 (I renamed combat_manager to CombatManager, you have to look at player, which should be Player):

how it's supposed to look like (4.4.1):

giving files a name in PascalCase (MyScript.gd) would be against the gdscript style, as files must be in snake_case and class names in PascalCase:
https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_styleguide.html#naming-conventions

Steps to reproduce

1 - go to project settings->autoloads
2 - create a new script file, give it a name in snake_case (my_autoload.gd)
3 - create a new script on a node and try to access the autoload:

func _ready() -> void:
4 - the suggestion will appear in snake_case

[optional]
5 - rename it in PascalCase (MyAutoload)
6 - now both names are suggested (snake_case and PascalCase), until godot is restarted.

Cannot re-produce on Godot-4.5.stable.official, ubuntu-24.04.

Steps:

• open godot-4.5
• create a new project
• create new script, default name is new_script.gd
• settings > globals > autoload, select new_script.gd, node name becomes NewScript

[Jesusemora]

@xuhuisheng the problem happens when using the Node Name: field and pressing Add.

In 4.4.1 typing new_file, then pressing Add, and creating the script, the file is given a class name in PascalCase.

the same doesn't happen in 4.5, the file is given a class name in snake_case.

I can reproduce the behavior difference, but it does seem reasonable to me that if you're asking for snake case you receive snake case. I went ahead and looked into this and it appears this was an intentional change made in #108642 to fix #108575, which is someone requesting that the node matches what the user asked for.

I'll note that the field you're entering new_file into is a Node name, not a file name, and so should be pascal cased according to the linked guidelines. Indeed, if you enter NewFile, you'll see that everything works as expected: the file is still snake cased automatically and the node name is pascal cased as you want it to be.
