I suppose it's a fair issue, but every campus building is on Google Maps
and presumably available in different ways on different search engines. I
certainly understand locking away access to reserving rooms, to the list of
buildings itself?

It's a late 90s programming problem trying to get data in a late 90s format
(OK, CSV blooms eternal) through a late 90s interface. I have no interest
in it.

But if anyone else wants in, enjoy.

Challenge problem for next Perl Mongers meeting:

Using these instructions from Brandon Case:
    SMAS also maintains the complete list along with mailing addresses
    in their Space Inventory application at
        https://www.smas.purdue.edu/inventory/
    Log in and then choose "Building(s)" from the navigation menu
    on the left. The entire table can be exported to PDF or CSV
    from the "Generate Report" button.
write a Perl 5 or Perl 6 program that uses Perl 5 and/or Perl 6 CPAN to
do the above and prints out all building abbreviations and building
names.  Your password must be kept encrypted in a separate file that
only you can read.

Subject: [Purdue-pm] Perl 6
Message-ID: <9980.1438087702@pier.ecn.purdue.edu>

Perl 6 is a much better language than Perl 5 in my opinion.  I'm using
it for simple programs now and am very happy with it.  Perl 5 has
    Comprehensive Perl Archive Network (CPAN)
    http://www.cpan.org
    153,637 open source Perl modules ready to download and use
and Perl 6 has
    Perl 6 Modules
    http://modules.perl6.org
    a few hundred Perl 6 modules (that aren't as mature
    or tested as Perl 5 modules)

Perl 5 and Perl 6 are both planned to be further developed and supported
in the future.  I like to use what I think are the best tools possible
so I plan to use Perl 6.  I suggest you use Perl 6 for small simple
programs that are not mission-critical now because trying to learn Perl
6 all at one time later may be prohibitively difficult.  Perl 6 is
experimental now, a production version will be released later---this
year has been mentioned---but the date has slipped before.

You can see the notes from my July 15, 2015 talk
    Let Perl 6 Do It
at
    https://engineering.purdue.edu/~mark/perl6-2015-07-15.pdf
(Go into full screen mode and hit the down arrow key repeatedly
to see the talk unfold (that works for me using acroread).
Warning: this relies a lot on what I said during the talk.)

Here is a complete Perl 6 program for Linux that defines command line
options (-d, --digits, -p, --passlen, -r, --rows, -u, --uppercase),
their default values, and prints $rows rows of $cols columns of $passlen
character long random passwords.

  #!/usr/new/bin/perl6

  sub MAIN
  (
      Bool :d(:$digits),
      Int  :p(:$passlen)   =  8,
      Int  :r(:$rows)      = 20,
      Bool :u(:$uppercase)
  )
  {
      my @char = 'a' .. 'z';
      ($digits)     and  @char.push('0' .. '9');
      ($uppercase)  and  @char.push('A' .. 'Z');
      my $cols = (78 / ($passlen + 1)).Int;
      for 1 .. $rows
      {
          # (
          #     Originally I had
          #         say (@char.roll($passlen).join xx $cols).join(' ');
          #     I like this representation because the code for rows
          #     is spread out over multiple lines (vertically) and the
          #     code for a single line is horizontal (one line).
          #     In practice, it doesn't take long to get used
          #     to the left-to-right reading of Perl 6 syntax with
          #         variable.method1.method2.method3
          #     and is so much easier to read than the Perl 5 syntax of
          #         function3(function2(function1(variable)))
          #     Perl 5 allows using no parentheses but you still need
          #     to read "from the inside out" to understand what's going on.
          # )
          # I divided what I originally had into two lines to
          # make it easier for beginners to read.
          # 1. Start with the array @char.
          # 2. Choose $passlen elements at random from it (.roll might
          #    choose the same element more than once, use .pick to
          #    choose the same element no more than once).
          # 3. That gives us a new array that we join together (take spaces
          #    out of) to form one password.
          # 4.  The xx $cols gives us $cols random passwords.
          my @pass = @char.roll($passlen).join xx $cols;
          # Print the $cols passwords on one line separated by spaces.
          say @pass.join(' ');
      }
  }

Here are some results of running the program

  % ./t.p6 -h
  Usage:
    t.p6 [-d|--digits] [-p|--passlen=<Int>] [-r|--rows=<Int>] [-u|--uppercase] 

  % ./t.p6 -p=5 --rows=3

Given a list of names, for example

Read the names from a Perl data section one name per line.
Do error checking to make sure you aren't given duplicate names.

Dear Mark,

That's a pretty interesting question (to me, at least), because I study 
retrieval trees in my research, and this is a very closely related 
topic.  I am eager to see what contributions that people make!  I am 
assuming you have an amazing way to do this in Perl 6.

Mark

Yes, just once.  After the program runs

               (This column is not part of the original problem
               definition,  I only added it to give an example of

Ab Abe         Abe Lincoln
Al Ala Alan    Alan Turing

Cath is not shortened to Cat because we'd get Cat Stevens
and Cathy Rigby confused.

It significantly changes the challenge if  you want the output to 
inlclude only the (possibly) shortened forms that are unique to one 
person.  In this case, there is no way to refer to Cat Stevens.  the 
logic to identify that Cat must be maintained for Cat Stevens, and 
further reductions of Cath must be rejected seems to be complex.  Is 
this included in the challenge?

I have a pretty straightforward way to solve this more complicated 
problem, as well as a very simple ways to solve the problem as 
originally stated in minimum time.

I'm only interested in the more complicated problem.  Sorry for the bad
problem description.  To summarize, read these names from a Perl data
section one name per line.
    Abe
    Alan
    Ben
    Cat
    Cathy
Do error checking to make sure there aren't duplicate names in the input.
Print the names under THESE NAMES one per line in your output.  Note that
the COULD REFER TO THESE PEOPLE column below is totally irrelevant to the
problem.  It was just added to better explain the problem.

    THESE NAMES    COULD REFER TO THESE PEOPLE
    -----------    --------------------------------------------------
    Ab Abe         Abe Lincoln
    Al Ala Alan    Alan Turing
    B Be Ben       Ben Carson
    Cat            Cat Stevens
    Cath Cathy     Cathy Rigby

    Cath is not shortened to Cat because we'd get Cat Stevens
    and Cathy Rigby confused.

Of course, your program should not just literally print
    Ab
    Abe
    [...]
The output should be dependent on the input data.    -mark
