#!/bin/perl # --- Documentation --- # Syntax : ./generate.pl agents_number [floor_number] # agents_number : can specify a number ranging from 2 to 500 ( upgradable by upgrading database ). number of visitors and residents are evenly splitted. # floor_number : number of floor in building ( not counting floor 0 ), ranging from 1 to whatever number is too big for perl. By default, number of floor is 25. # the scripts will generate two files : visitors.txt and residents.txt # visitors.txt syntax : each line is : visitor_name;resident_name\n # residents.txt syntax : each line is : resident_name;resident_floor;destination_floor\n # resident_floor is ranging from 1 to floor_number ( implying residents cant live at floor 0 ), while destination_floor is ranging from 0 to floor_number # written by Arthur Amalvy # last modification : 18/06/18 use strict; use warnings; use List::Util qw/shuffle/; die "Usage : generate.pl agents_number [floor_number]\nagents number range from 2 to 500\nfloor number range from 1 to +inf\n" if @ARGV == 0; my $total_nb = $ARGV[0]; die "Error : stupid amount of agents ($total_nb)\n" if $total_nb < 2; my $visitors_nb = int($total_nb / 2); my $residents_nb = $total_nb - $visitors_nb; my $floor_number = @ARGV > 1 ? $ARGV[1] : 25; die "Error : stupid floor number ($floor_number)\n" if $floor_number < 1; my $visitors_output_file_name = "visitors.txt"; my $residents_output_file_name = "residents.txt"; my $visitors_db_filename = "visitors.db"; my $residents_db_filename = "residents.db"; my @visitors = (); my @residents = (); open(my $visitors_db_file, $visitors_db_filename) or die "Error : no visitors database found \n"; open(my $residents_db_file, $residents_db_filename) or die "Error : no residents database found \n"; while(my $line = <$visitors_db_file>){ chomp($line); push(@visitors, $line); } while(my $line = <$residents_db_file>){ chomp($line); push(@residents, $line) if(@residents < $residents_nb); } die "Database is not big enough for $visitors_nb visitors\n" if @visitors < $visitors_nb; die "Database is not big enough for $residents_nb residents" if @residents < $residents_nb; @visitors = shuffle(@visitors); @residents = shuffle(@residents); open(my $visitors_output_file, '>', $visitors_output_file_name) or die "Error : couldn't create visitors output file."; open(my $residents_output_file, '>', $residents_output_file_name) or die "Error : couldn't create residents output file."; for(my $i = 0; $i < $visitors_nb; $i += 1){ print $visitors_output_file $visitors[$i] .
