I have this weird problem with "glob" command, which returns empty list
during application startup but works as expected afterwards.

The command is:

set paths [glob -nocomplain -types f -dir $homedir -- {*.materials}]

and homedir ist C:/Users/Public on Windows OS.

The command is so basic, I have no idea were to start debugging.

Any saving ideas?

Many thanks
Alexandru

I have no constructive suggestions, except to ask if you are REALLY SURE
that this is what's failing? Whenever I come across something like this
that is so basic it can't possibly be going wrong, it generally turns
out that it isn't going wrong and the fault is elsewhere.

I take it that you have confirmed that homedir is set to what you expect before executing the command you quote and that paths is set to
something you don't expect after executing it.

Other than the above, I can only offer sympathy and best wishes.

Many thanks Alan.
I just dicovered, that there is more to it and probably it's not the
glob commands fault at all.
I need to dig deeper...

Hello

which tcl/tk version you are using?
I did also have problems with 9.0 (see "glob problem" on tcl-core
mailing list)

Hint for debugging: Whenever you assume that it is failing, try this:

trace add execution glob enter echo

and if running outside of tkcon:

proc echo args { puts "TRACE: $args" }


This way, you'll see exactly how it is called and if e.g. homedir is
simply empty etc.

Nice trick!

In this specific case, I think it may be simpler to just remove the
option "-nocomplain" from glob and let it complain 🙂
