Aldebaran has asked for the wisdom of the Perl Monks concerning the following question:
Hello Monks,
I read an article this week about how perl was extinct, and thought, "that's an odd story to come up in my newsfeed while I'm installing Strawberry Perl." It got me to thinking, "how do they corral and interview every perl hacker out there?" I hope that the simple software tools I develop will be portable, where possible. That's why I spend time developing on MS, and I find that it is *unbearable* without perl.
I have a few scripts that are essential to me tapping out my confines and being able to converse about it. The first is this. I include the msdos equivalent of cat, which is type:
C:\Users\tblaz>type 1.modules.pl #!/usr/bin/perl use warnings; use 5.016; use File::Find; use Cwd; =pod =head1 DESCRIPTION This is a pretty good first attempt at figuring out where your modules + are. It is meant to follow the development of _Intermediate Perl_, a +nd I will adhere to the idioms. =cut my $current = cwd; find( \&pm_beneath, $current, ); say "--------------"; find( \&pm_beneath, "C:", ); sub pm_beneath { use File::Basename; my $basename = basename($File::Find::name); return unless $basename =~ /\.pm$/; print "$File::Find::name\n"; my $access_age = -A $basename; print " $basename\n"; printf "access age in days: %.2f\n", $access_age; } __END__ C:\Users\tblaz>
This gives me the output I'm looking for, but I generate a litany of errors on STDOUT whilst doing so. They're unwanted and clogging up STDOUT:
Microsoft Windows [Version 10.0.17763.615] (c) 2018 Microsoft Corporation. All rights reserved. C:\Users\tblaz>perl 1.modules.pl >5.txt ... at 1.modules.pl line 18. Can't opendir(C:/Users/tblaz/Documents/My Pictures): Invalid argument at 1.modules.pl line 18. Can't opendir(C:/Users/tblaz/Documents/My Videos): Invalid argument at 1.modules.pl line 18. Can't opendir(C:/Users/tblaz/Local Settings): Invalid argument at 1.modules.pl line 18. Can't opendir(C:/Users/tblaz/My Documents): Invalid argument at 1.modules.pl line 18. Can't opendir(C:/Users/tblaz/NetHood): Invalid argument at 1.modules.pl line 18. Can't opendir(C:/Users/tblaz/PrintHood): Invalid argument ... at 1.modules.pl line 20. Can't opendir(C:Templates): Invalid argument at 1.modules.pl line 20. C:\Users\tblaz>
How do rewrite this script to handle this error? edit These were only warnings, not errors. File::Find did what it should have, considering what junctions are. /edit
This has been my basic template for perlmonks writeups. It works except for the system call at the end:
#!/usr/bin/perl -w use 5.011; use Path::Tiny; use POSIX qw(strftime); # initialization that must precede main data structure # User: enter a subdirectory you would like to create # enter a subdirectory of this^^^ for output my $ts = "template_stuff"; my $output = "translations"; ## turning things to Path::Tiny my $abs = path(__FILE__)->absolute; my $path1 = Path::Tiny->cwd; my $path2 = path( $path1, $ts ); say "abs is $abs"; say "path1 is $path1"; say "path2 is $path2"; print "This script will build the above path2. Proceed? (y|n)"; my $prompt = <STDIN>; chomp $prompt; die unless ( $prompt eq "y" ); my $template_file = "1.tags.tmpl"; my $abs_to_template = path( $path2, $template_file )->touchpath; # script params my %vars = ( monk_tags => path( $path2, $template_file ), translations => path( $path2, $output ), book => 'monastery tags ', ); my $rvars = \%vars; my $return1 = write_monk_tags($rvars); say "return1 is $return1"; my $munge = strftime( "%d-%m-%Y-%H-%M-%S", localtime ); $munge .= ".monk.txt"; # use Path::Tiny to create and write to a text in relevant directory my $save_file = path( $vars{$output}, $munge )->touchpath; my $return2 = $save_file->spew_utf8($return1); say "return2 is $return2"; say "created file $save_file"; # system("Run 'C:\Program Files (x86)\Notepad++\notepad++.exe' $save_f +ile"); sub write_monk_tags { use warnings; use 5.011; use Text::Template; my $rvars = shift; my %vars = %$rvars; my $body = $vars{"monk_tags"}; my $template = Text::Template->new( ENCODING => 'utf8', SOURCE => "$body", ) or die "Couldn't construct template: $!"; my $return = "$vars{\"book\"}\n"; # User: change these quoted values for different order or tags my @buchstaben = qw/i p c pre readmore b/; for my $i (@buchstaben) { $vars{"symbol"} = $i; print "How many $i tag pairs would you like?: "; my $prompt = <STDIN>; chomp $prompt; if ( $prompt lt 1 ) { $prompt = 0; } while ( $prompt gt 0 ) { my $result = $template->fill_in( HASH => \%vars ); $return = $return . $result; --$prompt; } } return $return; } __END__
What I have had is
gedit $save_file &which works fine where gedit existed.
Notepad++'s executable is here:
'C:\Program Files (x86)\Notepad++\notepad++.exe'I threw the Run in there as a desperate attempt. How do I start up an executable and pass it the value of a lexical variable?
Thank you for your reply,
