Code Complete in Code Edit Node

Question

Hello, I’m trying to use Godots Code Edit Node but I cannot figure out how to use code complete, every script I attempt has failed. I’m just lookin for a basic script that works, Cheers.

You need to set the code_completion_enabled property to true.

CodeEdit

I’ve set it to true, but it still doesn’t work
This is the script I’ve attempted to use

extends CodeEdit

func _ready() -> void:
	code_completion_enabled = true
	code_completion_requested.connect(_request_code_completion)

func _request_code_completion(force):
	print("request")
	add_code_completion_option(CodeEdit.KIND_FUNCTION, "alert", "alert")
	update_code_completion_options(true)

What if you swap the two lines under ready func with each other, or somehow make it true after you already edit the text file.

[jimmybeen]

	code_completion_requested.connect(_request_code_completion)
	code_completion_enabled = true

Didn’t fix it

[jomi]

What about the confirm_code_completion function? It seems to say in the documentation that it replaces current text with selected text.

[jimmybeen]

How do I do that?

The code edit won’t invoke a completion request when typing. Does it work when using Ctrl + Space? If so, you might be missing a connection from TextEdit.text_changed to CodeEdit.request_code_completion

Also if you are using the virtual method _request_code_completion you don’t need to connect it to the code_completion_requested signal (the signal will never be emitted), see this proposal for info on how they interact.

[jimmybeen]

When I press ctrl + space it did work, but I don’t think code edit has a text_changed API, well I couldn’t find it

[holonproduction]

It’s a signal on TextEdit which CodeEdit inherits from

[jimmybeen]

Hey everyone, I have figured it out

extends CodeEdit

func _ready() :
	text_changed.connect(code_request_code_completion)
	code_completion_enabled = true

func code_request_code_completion():
	add_code_completion_option(CodeEdit.KIND_FUNCTION, "[display text]", "[text inserted into code]")
	update_code_completion_options(true)

The code above makes an sends an autocomplete to the user without ctrl+space

Code for future people who would like people to still use ctrl+space

extends CodeEdit

func _ready():
	code_completion_enabled = true
	# code_completion_requested.connect(_request_code_completion) (Not Needed)

func _request_code_completion(force):
	add_code_completion_option(CodeEdit.KIND_FUNCTION, "[display text]", "[text inserted into code]")
	update_code_completion_options(force)

Thank you, and thanks to @holonproduction

code_completion_requested.connect(_request_code_completion) shouldn’t be necessary in your second example. The implementation of _request_code_completion overrides the default implementation which would emit the signal.
