how to create the path automatically

baxy77bax has asked for the wisdom of the Perl Monks concerning the following question:

hi,

i have this problem where i would like to create a path and directories automatically. my script is :

use strict;
use lib "./Lib";
use Main;


my $control = Main->new();


print "finished \n";
[download]

so when i initialize Main, the sub that checks if there is a path to my specific variable is started. like :


package Main;
use strict;
use File::Path qw(make_path remove_tree);

##################################################
sub new {
##################################################

my ($class)=@_;

craete_path();

my $hash = {};

bless ($hash,$class);

}



sub create_path {

# here it first checks if the path  already exists or not, and if ther
+e is no path, then it creates a path (with all necessary directory's)
+.

}

1;

so my question is : do people tend to do it like this or is there some other more practical/elegant way to do it ?

thanks

I don't understand why you need to create an object and call to subs/methods before actually calling mkpath. What's wrong with simply writing: `use File::Path qw(mkpath); my $path = 'path/to/create'; mkpath($path) unless -e $path;` [download]	[reply] [d/l]

`mkpath($path) unless -e $path;` The `unless` clause is not necessary here. Further, this would die if the path can't be created, so unless the OP wants this exception to propagate, it's maybe better written as `eval { mkpath($path) }; if($@) { ... }` [download] -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]

now this is a good question, and the answer is : because i didn't think this through , i just automatically copy/past/edit a ~~peace~~ piece (i was learning my english by VUK :) ) of my code. sorry (++)	[reply]

The function is called `mkpath`, not `make_path`. Also, you don't need to check for the existence; `mkpath` takes care of this by itself. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]
