the modification is probably here. can't you show us everything up

Sorry. It's a bit much. That's why I was holding back. Here's the whole
script.
require 'kirbybase'
Dir.chdir("E:/pagecounts")
#First, create the database table.
db = KirbyBase.new
# If table exists, delete it.
db.drop_table(:pageinfo) if db.table_exists?(:pageinfo)
pageinfo_tbl = db.create_table(:pageinfo,
:filename, {:DataType=>:String,
:Index=>1},
:lconstant, :String,
:compcode, :String,
:primecode, :Integer,
:costcenter, :String,
:acctgroup, :Integer,
:blank, :String,
:description, :String,
:pagecount, :Float,
:sjccode, :String,
:fullname, {:DataType=>:String,
:Index=>2}
)
# Import the csv file.
pageinfo_tbl.import_csv('McArdle_indexes.csv')
=begin
Parse each postscript print file in the polled directory. Create
variables for:
the number of pages in each file; the number of blank pages in each
file; and,
what exact pages are blank.
=end
Dir.glob("*.ps").each do |psfile|
file_contents = File.read(psfile)
file_contents.scan(/\%\%Pages: (\d{1,5})+\n/) do
totalpages = $1
if (totalpages.to_i % 2) !=0 then
newtotalpages = totalpages.to_i + 1
file_contents << "\%\%Blank page for Asura.\n\%\%Page:
#{newtotalpages.to_i}\nshowpage\n"
File.open(psfile, "w") { |f| f.print file_contents }
FileUtils.touch(psfile)
end
=begin
Find blank pages in the postscript file. Look for the regular expression
that
sees a page callout followed by postscript data that does not include
data in parentheses. Any type on a postscript page is enclosed in
parentheses,
so, that's why this is a legitimate search. Blank pages have no
parenthesized
data.
=end
blanks =
file_contents.scan(/\%\%Page: [()0-9{1,5}]
([0-9]{1,5})\n[^\(.*\)]\%\%Page/)
do |match|
blanks.push($1)
end
file_contents.scan(/\%\%Blank page for Asura.\n/) do |match|
blanks.push(totalpages.to_i + 1)
end
=begin
Open a "pageinfo" file. Put page information about the file into it.
Notice that the variable for the total number of pages differs depending
on whether a "newtotalpages" variable exists. And, that variable only
exists if the original page count was odd and a blank had to be added.
=end
filename = File.basename("#{psfile}", '.ps')
pageinfofile = File.basename("#{psfile}", '.ps') + ".pageinfo"
File.open("E:/pagecounts/#{pageinfofile}", "a") do |fileinfo|
if newtotalpages then
fileinfo << #{filename}\n << "Total number of pages in this PDF:
#{newtotalpages}\n" <<
"Number of blank pages in this PDF: #{blanks.size}\n" <<
"Specific pages that are blank in this PDF: " <<
"#{blanks.join(', ')}\n"
else
fileinfo << #{filename}\n <<
"Total number of pages in this PDF: #{totalpages}\n" <<
"Number of blank pages in this PDF: #{blanks.size}\n" <<
"Specific pages that are blank in this PDF: " <<
"#{blanks.join(', ')}\n"
end
end
end
end
=begin
Back to the database table. . . .
Query against the table and match the filename in the directory with
whichever entry
in the "filename" column of the table matches. Then, if there's a match,
populate
the "pagecount" field in that row of the table with the variable for the
page count, as
found above. That variable name is "newtotalpages."
=end
Dir.glob("*.ps").each do |dirfile|
result = pageinfo_tbl.select(:filename) { |r| dirfile =~
Regexp.new(r.filename) }
pageinfo_tbl.update { |r| r.name ==
{filename}.set(:pagecount=>#{newtotalpages}) } unless result.nil?
end
