  • Pull specific information from a long list with Perl

    - by melignus
    The file that I've got to work with here is the result of an LDAP extraction but I need to ultimately get the information formatted over to something that a spreadsheet can use. So, the data is as follows: DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: John Doe name: ##userName DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: Jane Doe name: ##userName DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: Ted Doe name: ##userName The format that I need to export to is: firstName lastName userName firstName lastName userName firstName lastName userName Where the spaces are tabs so I can then impor that file into a database. I have experience doing this in VBScript but I'm trying to switch over to using Perl for as much server administration as possible. I'm not sure on the syntax for what I want which is basically while not endoffile{ detect "displayName: " & $firstName & " " & $lastName detect "name: ##" & $userName write $firstName tab $lastName tab $userName to file } Also if someone could point me to a resource specifically on the text parsing syntax that Perl uses, I'd be very grateful. Most of the resources that I've come across haven't been very helpful.

  • Perl program for extracting the functions alone in a Ruby file

    - by thillaiselvan
    Hai all, I am having the following Ruby program. puts "hai" def mult(a,b) a * b end puts "hello" def getCostAndMpg cost = 30000 # some fancy db calls go here mpg = 30 return cost,mpg end AltimaCost, AltimaMpg = getCostAndMpg puts "AltimaCost = #{AltimaCost}, AltimaMpg = {AltimaMpg}" I have written a perl script which will extract the functions alone in a Ruby file as follows while (<DATA>){ print if ( /def/ .. /end/ ); } Here the <DATA> is reading from the ruby file. So perl prograam produces the following output. def mult(a,b) a * b end def getCostAndMpg cost = 30000 # some fancy db calls go here mpg = 30 return cost,mpg end But, if the function is having block of statements, say for example it is having an if condition testing block means then it is not working. It is taking only up to the "end" of "if" block. And it is not taking up to the "end" of the function. So kindly provide solutions for me. Example: def function if x > 2 puts "x is greater than 2" elsif x <= 2 and x!=0 puts "x is 1" else puts "I can't guess the number" end #----- My code parsing only up to this end Thanks in Advance!

  • how to store a file handle in perl class

    - by Haiyuan Zhang
    please look at the following code first. #! /usr/bin/perl package foo; sub new { my $pkg = shift; my $self = {}; my $self->{_fd} = undef; bless $self, $pkg; return $self; } sub Setfd { my $self = shift; my $fd = shift; $self_->{_fd} = $fd; } sub write { my $self = shift; print $self->{_fd} "hello word"; } my $foo = new foo; My intention is to store a file handle within a class using hash. the file handle is undefined at first, but can be initilized afterwards by calling Setfd function. then write can be called to actually write string "hello word" to a file indicated by the file handle, supposed that the file handle is the result of a success "write" open. but, perl compiler just complains that there are syntax error in the "print" line. can anyone of you tells me what's wrong here? thanks in advance.

  • User input in Perl with IO::Socket

    - by David
    I am trying to make a perl program which allows a user to input the host and the port number of a foreign host to connect to using IO::Socket. It allows me to run the program and input a host and a port but it never connects and says "Could not connect to [host] at c:\users\USER\Documents\code\perl\sql.pl line 18, line 2." What am i doing wrong with this code shown below? And also, how can i have input validation on my host, which can either be a host name or an ip address? Thanks a bunch! Code Below use IO::Socket print "Host to connect to: "; chomp ($host = <STDIN>); print "Port to connect with: "; chomp ($port = <STDIN>); while(($port > 65535) || ($port <= 0)){ print "Port to connect with [Port > 0 < 65535] : "; chomp ($port = <STDIN>); } print "\nConnecting to host $host on port $port\n"; $socket = new IO::Socket::INET ( LocalHost => '$host', LocalPort => '$port', Proto => 'tcp', Listen => 5, Reuse => 1 ); die "Could not connect to $host";

  • Server Push CGI Perl Problem writing the JPEG image

    - by Jujjuru
    I am a beginner in Perl CGI etc. I was experimenting with server-push concept with a piece of perl code. It is supposed to send a jpeg image to the client every 3 seconds. Unfortunately nothing seems to work. Can somebody help identify the problem? Here is the code.... use strict; # turn off io buffering $|=1; print "Content-type: multipart/x-mixed-replace;"; print "boundary=magicalboundarystring\n\n"; print "--magicalboundarystring\n"; #list the jpg images my(@file_list) = glob "*.jpg"; my($file) = ""; foreach $file(@file_list ) { open FILE,">", $file or die "Cannot open file $file: $!"; print "Content-type: image/jpeg\n\n"; while ( <FILE> ) { print "$_"; } close FILE; print "\n--magicalboundarystring\n"; sleep 3; next; } EDIT: added turn off i/o buffering, added "use strict" and "@file_list", "$file" are made local

  • Define an empty array in Perl class new()

    - by Laimoncijus
    Hi, I am just beginner with Perl, so if it sounds stupid - sorry for that :) My problem is - I am trying to write a class, which has an empty array, defined in constructor of a class. So I am doing this like this: package MyClass; use strict; sub new { my ($C) = @_; my $self = { items => () }; bless $self, ref $C || $C; } sub get { return $_[0]->{items}; } 1; Later I am testing my class with simple script: use strict; use Data::Dumper; use MyClass; my $o = MyClass->new(); my @items = $o->get(); print "length = ", scalar(@items), "\n", Dumper(@items); And while running the script I get following: $ perl my_test.pl length = 1 $VAR1 = undef; Why am I doing wrong what causes that I get my items array filled with undef? Maybe someone could show me example how the class would need to be defined so I would not get any default values in my array? Thanks!

  • Firing through HTTP a Perl script for sending signals to daemons

    - by Eric Fortis
    Hello guys, I'm using apache2 on Ubuntu. I have a Perl script which basically read the files names of a directory, then rewrites a text file, then sends a signal to a daemon. How can this be done, as secure as possible through a web-page? Actually I can run the code below, but not if I remove the comments. I'm looking for advise considering: Using HTTP Requests? How about Apache file permissions on the directory shown in code? Is htaccess enough to enable user/pass access to the cgi? Should I use a database instead of writing to a file and run a cron querying the db with permission granted to write and send the signal? Granting as less permissions as possible to the webserver. Should I set a VPN? #!/usr/bin/perl -wT use strict; use CGI; #@fileList = </home/user/*>; #read a directory listing my $query = CGI->new(); print $query->header( "text/html" ), $query->p( "FirstFileNameInArray" ), #$query->p( $fileList[0] ), #output the first file in directory $query->end_html;

  • Perl, strings, floats, unit testing and regexps!

    - by Chris R
    OK, as a preface this question potentially is 'stupider' than my normal level of question - however this problem has been annoying me for the last few days so I'll ask it anyway. I'll give a mock example of what my problem is so I can hope to generalize it to my current problem. #!/usr/bin/perl -w use strict; use Test::More 'no_plan'; my $fruit_string = 'Apples cost $1.50'; my ($fruit, $price) = $fruit_string =~ /(\w+)s cost \$(\d+\.\d+)/; # $price += 0; # Uncomment for Great Success is ($price, 1.50, 'Great Success'); Now when this is run I get the message # Failed test 'Great Success' # got: '1.50' # expected: '1.5' To make the test work - I either uncomment the commented line, or use is ($price, '1.50', 'Great Success'). Both options do not work for me - I'm testing a huge amount of nested data using Test::Deep and cmp_deeply. My question is, how can you extract a double from a regexp then use it immediately as a double - or if there is a better way altogether let me know - and feel free to tell me to take up gardening or something lol, learning Perl is hard.

  • How to stop input in Perl?

    - by user1472747
    First time poster and part time perl noobie. I'm making a reflex game. Here's the output - __________________________________________________________________________ Reflex game initiated. Press ENTER to begin the game, and then press ENTER after the asterisks are printed to measure your reflexes!. ************************* Your result: 0.285606 seconds. logout [Process completed] __________________________________________________________________________ There's one small problem though - There's 0-10 seconds (based on a random variable) after you press enter to start the game and before the stars are printed. During that time, if the player presses ENTER, it's logged as their reflex time. So I need a way to stop my code from reading their ENTER button before the stars are printed. The code - #!/usr/bin/perl use Time::HiRes qw(sleep); use Time::HiRes qw(gettimeofday); #random delay variable $random_number = rand(); print "Reflex game initiated. Press ENTER to begin the game, and then press ENTER after the asterisks are printed to measure your reflexes!.\n"; #begin button $begin = <>; #waits x milliseconds sleep(10*$random_number); #pre-game $start = [ Time::HiRes::gettimeofday() ]; print "\n****************************\n"; #user presses enter $stop = <>; #post game $elapsed = Time::HiRes::tv_interval($start); #delay time print print "Your result: ".$elapsed." seconds.\n";

  • Can't post with Perl's Net::Blogger

    - by Ovid
    I'm trying to automatically post to blogger using Perl's Net::Blogger but it keeps returning false and not posting. The main portion of my code looks like this: use Net::Blogger; my $blogger = Net::Blogger->new({ debug => 1, appkey => '0123456789ABCDEF', # doesn't matter? blogid => $blogid, username => $username, password => $password, }); say 'got to here'; my $result = $blogger->newPost({ postbody => \'<p>This is text</p><hr/><p><strong>Whee!</strong></p>', publish => 1, }); say 'done posting'; use Data::Dumper; print Dumper($result); Sure enough, $result is 0 and in checking the blog, nothing has been posted. The error I'm getting when I enable debugging is: Element '' can't be allowed in valid XML message. Died. at /Library/Perl/5.10.1/SOAP/Lite.pm line 1410. What am I doing wrong? If you can suggest an alternative to Net::Blogger, that would be fine.

  • How to end a thread in perl

    - by user1672190
    I am new to perl and i have a question about perl thread. I am trying to create a new thread to check if the running function is timed out, and my way of doing it is as below. Logic is 1.create a new thread 2.run the main function and see if it is timed out, if ture, kill it Sample code: $exit_tread = false; # a flag to make sure timeout thread will run my $thr_timeout = threads->new( \&timeout ); execute main function here; $exit_thread = true # set the flag to true to force thread ends $thr_timeout->join(); #wait for the timeout thread ends Code of timeout function sub timeout { $timeout = false; my $start_time = time(); while (!$exit_thread) { sleep(1); last if (main function is executed); if (time() - $start_time >= configured time ) { logmsg "process is killed as request timed out"; _kill_remote_process(); $timeout = true; last; } } } now the code is running as i expected, but i am just not very clear if the code $exit_thread = true works because there is a "last" at the end of while loop. Can anybody give me a answer? Thanks

  • Meaning of NEXT in Linked List creation in perl

    - by seleniumnewbie
    So I am trying to learn Linked Lists using Perl. I am reading "Mastering Algorithms with Perl" by Job Orwant. In the book he explains how to create a linked list I understand most of it, but I just simply fail to understand the command/index/key NEXT in the second last line of the code snippet. $list=undef; $tail=\$list; foreach (1..5){ my $node = [undef, $_ * $_]; $$tail = $node; $tail = \${$node->[NEXT]}; # The NEXT on this line? } What is he trying to do there? Isn $node a scalar, which stores the address of the unnamed array. Also even if we are de-referencing $node, should we not refer to the individual elements by an index number example (0,1). If we do use "NEXT" as a key, is $node a reference to a hash? I am very confused. Something in plain English will be highly appreciated.

  • Perl Cookie not working

In Perl I use this code: my $browser = LWP::UserAgent->new; my $resp = $browser->get( $url, 'User-Agent' => 'MySpider/1.0' ); #Cookie Setup my $cookies = HTTP::Cookies->new(); $cookies->set_cookie(1,'age_check', '1','/','.example.com/', 80, ,0,3354512128, 0); $browser->cookie_jar($cookies); The Site is setting the Cookie with JavaScript function saveSplash(domain) { var expDate = new Date(); expDate.setTime(expDate.getTime()+(1*24*3600*1000)); setCookie("age_check", 1, expDate, '/', domain); setCookie("screen_width", getScreenWidth(), expDate, '/', domain); } This is the Cookie saved by my browser: age_check 1 example.com/ 1088 3354512128 30140182 2646218624 30139981 Any idea what I am doing wrong?

  • How can I redirect the output of Perl's system() to a filehandle?

    - by syker
    With the open command in Perl, you can use a filehandle. However I have trouble getting back the exit code with the open command in Perl. With the system command in Perl, I can get back the exit code of the program I'm running. However I want to just redirect the STDOUT to some filehandle (no stderr). My stdout is going to be a line-by-line output of key-value pairs that I want to insert into a mao in perl. That is why I want to redirect only my stdout from my Java program in perl. Is that possible? Note: If I get errors, the errors get printed to stderr. One possibility is to check if anything gets printed to stderr so that I can quite the Perl script.

  • perl: tk: a way/widget that allows pixel level control over the output

    - by chhh
    I want something like a canvas, but where i'd be able to manipulate pixels easily in addition to all the provided geometries, that can be drawn on canvas. Is it possible to embed something like GD::Image into a canvas? So then I maybe could make the image transparent and set some pixels in it (GD::Image-setPixel()) positioning it over the canvas? ps: well, that doesn't necessarily have to be perl, as there seem to be bindings for all the libs for most scripting (and not only) languages.
