in reply to Why I hate File::Find and how I (hope I) fixed it

Sorry for a very late reply to an old post.

I do not see how is

# create various wnated functions my $wanted= make_wanted( \&wanted_1, 'toto', 'tata'); find( $wanted, '.'); print "\n";
better than
find( sub{ wanted_1( 'toto', 'tata')}, '.'); print "\n";

If you did want to play around I'd suggest something a bit different.

use File::Find; sub callback (&) { my $sub = shift(); return sub { my @args = @_; return sub { $sub->(@args); } } } my $wanted = callback { my ($some, $params) = @_; print "wanted( $some, $params); \$_ = $_\n"; # ... }; find( $wanted->(1,2), 'd:\temp\copy'); find( $wanted->(20,19), 'd:\temp\copy');
or even better
#... *wanted = callback { my ($some, $params) = @_; print "wanted( $some, $params); \$_ = $_\n"; # ... }; find( wanted(1,2), 'd:\temp\copy'); find( wanted(20,19), 'd:\temp\copy');

[tye]: Is it just me, or do most python things have terrible logging/errors?
[LanX]: but but but ... the errors are nicely formatted!
[tye]: 1) The python stack traces show you the names of variables, not the values of variables. Almost never informative.
[LanX]: do you have a py job now?
[tye]: Right now I have errors trying to fetch stuff from graphite. It says 'apps not ready, check startup logs'. I eventually find the startup logs and see 'no apps found'. Looking for fixes to this problem...
[LanX]: no idea ... ask py monks! ;-p
[tye]: it turns out that this can be caused by almost anything going wrong. If you want to know what caused the problem, you have to try to load each app by-hand to see what problems it is having, because none of those will be logged.
[tye]: No, I write more Perl than py at work. But I have to deal with plenty of py things.
[tye]: py monks would just be offended.
