Re: How to close a file if successfully opened

I found a solution:

catch {
    try {
        set fh [::ini::open $::config::filename -encoding utf-8 r]
        set ::config::geometry \
            [::ini::value $fh Window geometry [wm geometry .]]
        tk scaling [::ini::value $fh Window scale [tk scaling]]
        ttk::style theme use \
            [::ini::value $fh Window theme [ttk::style theme use]]
        set ::config::tab [::ini::value $fh Window tab]
    } finally {
        if {[info exists fh] && $fh ne ""} {
            ::ini::close $fh
        }
    }
} ;# ignore if file not found
