Double clicking on a word can select prior not character symbol

[bsil78]

Godot version

4.0-beta6

System information

Windows 10

Issue description

Word selection is not stopping to some symbols on left of word (tested +=>$) if prior symbol of this character is not a word or spacing character which is not very practical for most of them ; no problem with ,!-<%;* however.

It seems to be right too in Label and RichTextLabel text edit box... but there rules could be different ?

I tested too €uro, ₩on, ¥en as examples, but those characters arez similar to letters and I am less anoyed to see them selected...

Steps to reproduce

Just open any script, exit any Label or RichTextLabel text and type examples below,
then double-click on word in order to select it :

• "var1==var2" : if I double-click on var2, =var2 is selected
• "func myFunc()->int:" : if I double-click on int, >int is selected
• "this is test for ++tag" : if I double-click on tag, +tag is selected

Minimal reproduction project

Any project, in any script or Label text edit box, or RighTextLabel text edit box

I searched for similar issue with :
is:issue is:open label:bug label:topic:editor word selection

And only one related I found was a graphical issue :
#55588

[bsil78]

Found #56402 which is similar but restricted to $

[bsil78]

I found that putting space before things is an acceptable workaround ;
what bothered me was difference of behavior for different symbols...

[bsil78]

In fact I was chocked because Godot 3.5.x do not behave like that... it feels like some regression to me.

You can change the list of non-word characters for the purpose of text navigation/selection in the Editor Settings, but I agree the default value should be changed to get the 3.x behavior back. Feel free to open a pull request for this 🙂

I can't find any setting.

This seems to be caused by TextServerAdvanced's u_ispunct() which doesn't consider certain characters as punctuation. Using TextServerFallback matches the 3.x behavior because it uses Godot's is_punct().

A way to solve this would be to add custom_punctuation to CodeEdit.
Also, we should maybe match is_punct()'s behavior with u_ispunct().

Differences between the two functions:

This also affects using ctrl+left/ctrl+shift+left/ctrl+backspace to move/select/delete the word to the left.

On more than one occasion, this has introduced a bug: an inadvertent change of a foo>=bar comparison into foo>qux when I edited the variable name on the right hand side.

(And on many occasions it has caused a foo==bar to be inadvertently changed to foo=qux, but at least this one is caught by assignment being disallowed in expressions in GDScript.)

In addition, presumably due the same cause, there is a discrepancy when editing GDScript code between $Node, where the caret/selection is placed before the $ versus %Node, where the caret/selection is placed after the %.

(4.2 beta5 tests)

As I can see, most work properly but when there is several ponctuation characters before selection ; exemples :
a==b => (same if first = is + or - instead) double-clicking b willl select =b, a=b is fine though as it select only b then
func(arg)->void; => double-clicking void willl select >void, func(arg) -> void is fine though as it select only void then
print("test >>word") => (notice the space) double-clicking word willl select >>word ; but should select only word
print("test>>word") => (notice no space) double-clicking word willl select >word ; but should select only word
