Allow get_word_at_pos() function support symbols (@$# ....)

[JBingrun]

Describe the project you are working on

I'm building a custom text editor to write code with custom extensions.

Describe the problem or limitation you are having in your project

I try to get the current text that the user input and check if it matches anything keyword I defined. If matched, it will trigger the auto-completion and give a list for users to choose from. I search a bit and found that there are two functions that might suit my need in Godot 4. One is get_word_at_pos() and the other is get_word_under_caret().
get_word_at_pos() works great only does not support symbol and get_word_under_caret() need a bit workaround and I found it support $ and ~ but still not for all. So I was stuck with no way to get the full string that the user input with symbols.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Allow the get_word_at_pos() function to support symbols so any kind of custom code using symbols very often can use it more effectively.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Code:

_text_edit = $TextEdit
var _caret_pos: Vector2 =_text_edit.get_caret_draw_pos()
print("Current input text: " + _text_edit.get_word_at_pos(_caret_pos))

In extEdit when user input:
===Test Code===@#$

Console will print full of them:
Current input text: ===Test Code===@#$

If this enhancement will not be used often, can it be worked around with a few lines of script?

I didn't find any other way to do this at this moment.

Is there a reason why this should be core and not an add-on in the asset library?

TextEdit node is for building custom edit environments and more customizable for different situations will be more useful.

See godotengine/godot#46721. You should be able to override word break characters with an empty list when adding text to the TextEdit node to control the behavior of get_word_at_pos() and get_word_under_caret().

Thanks for the reply, can't tell I do understand how to achieve my goal, anyway, I follow the example:

var a = TextParagraph.new()
a.custom_punctuation = "R"
a.add_string("test.test_testRtest test", get_theme_font("font"), 16)
print("A: ", TextServerManager.get_primary_interface().shaped_text_get_word_breaks(a.get_rid()))
#A: [(0, 14), (15, 19), (20, 24)]

And Godot stuck at setting custom_punctuation value and give me this error message:

Invalid set index 'custom_punctuation' (on base: 'TextParagraph') with value of type 'String'.

The type of custom_punctuation is a string, isn't it?
