I can only test Windows.
This function is_word_char() works fine.
The problem on mac does not seem to be an issue with is_word_char().

(
It looks like changes to 'is_word_char()' were not applied at compile time.
Wouldn't the changed to 'is_word_char()' have been applied at compile time?
)

If the new code matches the behavior of native windows, then check if ctx.os() == OperatingSystem::Windows

The is_word_char() function simply returns a bool value, so I think it's a good idea to keep it that way.
I think it would be better to fix the mac issue later.
Otherwise, please edit as you wish.

I want to match how text editing works natively on whatever platform egui runs on.

If double-clicking foo-bar selects both foo and bar on windows, then let's make it work like that, but only on Windows (because on Mac, words don't extend across hyphen on double-click).

I don't know how Windows works though.

yes. In windows everything works fine.
Not only foo-bar, but also URL, e-mail, path, UTF8 characters (Korean), etc. all work well.
I think the reason it doesn't work on mac has nothing to do with this function.

What emilk is saying is that egui should work exactly like other programs in each operating system. So you should probably change:

    if matches!(
        c,
        '_' | '-' | ':' | '/' | '.' | '\\' | '@' | '#' | '?' | '='
    )

to

    if matches!(c, '_')

In Notepad on Windows 10, many things such as ., _, -, ;, (, ) are selected together when double-clicked.
And what is selected when double-clicking is unique to egui and does not need to be copied by other programs.
