Topic: More Perl assistance?
Anonymous A started this discussion 12 years ago #34,105
In my class we have to...
create a script for Seminar Workshop. The script displays, on a Web page, the number of people registering for each of four different seminars. The script also displays the total number of registrants. The registration data is stored in a file named c05ex5.txt.
Open the c05ex5.txt file, which is contained in the cgi-bin/chap05 directory, in a text editor. The file contains 10 records. Each record consists of two fields: the registrant's name and a seminar number. (Seminar 1 is the Computer Maintenance seminar, 2 is the Microsoft Office seminar, 3 is the Unix Essentials seminar, and 4 is the CGI/Perl seminar.
Create a script named c05ex5.cgi that displays a Web page similar to the one shown in Figure 5-22. The Web page displays the number of people registered for each seminar, and the total number of registrants. (Hint: Use an array of counters to calculate the number of people registering for each seminar.)
This is the code I had written so far.

When I tested it in cmd it gives me these errors.
> Use of uninitialized value $seminar in hash element at c05ex5.cgi line 32.

Here is my HTML code. I've used my other projects from this chapter as a source to look upon, but I have no idea how to apply this to a name field. I used a name field as it seemed appropriate for this assignment.

Does one of the input lines not have a tab character, or is empty perhaps? That would cause your split to fail.

Ok so the problem is that on line 57 in that pastebin it's not splitting correctly on \t? It seems to me that:
1) On line 46 you're writing a | and not a \t
2) That the file will always have a final, empty, line which thus will never contain a \t, or a |, this it will not be splittable when iterated over

@previous (F)So can you not use a \t character to separate the two variables?
I noticed there is another problem. When I test the script in cmd. It doesn't tally up the total number of selections for each seminar.
It's suppose to show a page that shows how many signed up for what seminar and then show the total of all registered participants.
I'm also including an image of how the finished product should look.

You can, you just need to use it both when reading and writing. When writing you use | when reading you use \t.

I have to go, but a few observations...
The @ is used for arrays, and % is used for hashmaps if I recall correctly. Your seminar_count is an array, so it cannot have strings as keys. You want a hashmap, probably.
You use the seminar variable twice... Once for "$seminar = param('Seminar');" and once for "($name, $seminar) = split(/\t/, $rec);". The second one is not scoped with my, so that might be bleeding out.
http://pastebin.com/M2K5B9gr kind of works, but not with strict mode enabled. Not sure why it's complaining there.

You probably are. Just trace through the code and evaluate each instruction. Write it down on paper if you need to. Someone who has been doing this for 20 years could probably just tap out a few lines and be done. That's not you yet. PERL is fucking nuts and is regarded, even by old C programmers who don't wash or shave and use emacs as if it were an operating system, as crazy new-fangled skullduggery. PERL is hard. It's complex.
People who write code for a living have written code, and then revised it, and then revised it, and then realized they were making run-on sentences, and then they realized that they were going about the entire task in completely the wrong way; then they revised the code some more. And then then realized the whole idea was silly and the "brilliant" function they wrote to do $X can be accomplished in nine lines of code posted by some neckbeard on a UNIX forum in 2005. Ho-hum. Welcome to programming.

Its more better to give member variables a prefix so that they can easily be distinguished from normal variables.
AND I see pgms C++ that use m_ and other programs that use more better mul_ & s_ for static and g_ for global, yet many fail to make programs readable in as English.

I R not a code riter. I R a Hardware Engineer that uses a mass of code to run Hardware. Run in2 code with blanks in the text of array keys. AND I wood much rather see integer values for i and j rather than characters. Coding in say 4GLTE systems use a mass of multi-dimensional arrays. Then someone comes along with "$i,$j" parsed into a string that is more better then "$i, $j"
ah n remember I am burdened with dyslexia so make ur coding read as simple English. PERL is usually close nuff for me. C++ not so much.

I asked on the discussion boards for the course. Someone said...
"You should look at your split function again. You also don't need to save anything in this script.
You should also delete the three extra records from your c05ex5.txt file."
I assume he spotted the same thing with the split function as you all did, but I'm confused about the last 2 sentences.

Can someone here check my code?
> Instruction
> Create a script named c05ex4b.cgi. The script should display the contents of the c05ex4.txt file on a Web page. Display each record (name, serial number, model number, and operating system letter) on a separate line, with a tab separating each field in the record.You will need to use the pattern /\|/ in the split function. As you learned in Chapter 3, the backslash alerts Perl to ignore the special meaning of a character and simply treat the character—in this case, the pipe symbol—verbatim.

I really would like to, but St. Patrick's Day and some douche-waffle thinks he can drink more Guinness than I can. I feel bad for him.

I don't feel bad. I'm a little amazed I'm still awake. Please let us know how it works out. I feel like we're all learning PERL along with you.

I just learned that variables do not need to be declared if you remove use strict.

I need some more help, but I think I almost got it.
I need to make the names appear until their specific job. It currently displays one name, but not both. I assume there is something wrong with my for loop.
Here's my code: http://pastebin.com/J0MSAVdY

What are these instructions asking exactly? Does it call for a sub function?
> g. Modify the script so that it removes any leading and trailing spaces from the input data.
> h. Modify the script so that it can handle a sales amount entered with a dollar sign and/or comma. (Hint: Use the tr/// operator to remove these characters from the number.)
> i. Modify the script so that it can handle a bonus rate entered as a whole number, a floating-point number, and a number with a percent sign—for example, 5, .05, 5.0, 5.0%, and 5%.
If anyone has any understanding of how the tr///, m//, or s/// operators work, please help me out here. I can understand the jist of it just fine though.

Have you tried reversing the polarity? It's probably a long shot, but it might make things clearer.
Hope that helps.

How many people on MC are familiar with Perl, anyway?
