Re: How to close a file if successfully opened

I tried using both trap and finally but it didn't work.
Having seen your code quotes I realise that I made a mistake with the
syntax, so here's what I used in the end:

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]
} trap {POSIX ENOENT} {} {
    ;# do nothing and rely on defaults
} finally {
    if {[info exists fh] && $fh ne ""} {
        ::ini::close $fh
    }
}

I'd gone wrong in the trap; I'd forgotten the second set of braces.

Thank you.
