Hello!

I have a string. It looks like 'just a test'. Saw a solution posted before.
$text=~s/([^ ]{3})(?=[^ ])/$1-/g; # split words longer than 3 characters
I get 'jus-t a sam-ple' after I run this code.
That's totally what I'm looking for.

But the problem is I might have special tags in this string like 'ju[color=1]s[/color]t a tes[color=2]t[/color]'. These tags are converted to HTML tags later. I need to skip [...] when I count number of characters in a word. The output should be "ju[color=1]s-[/color]t a tes-[color=2]t[/color]" or "ju[color=1]s[/color]-t a tes-[color=2]t[/color]". Both variants are ok.

It should have a pretty easy solution using regex. But I don't know how to do it.

Thank you!
