Data output

Ruby
1

I am processing data from an array which basically involves me searching
for specific information and outputting the results that match eg.

…
if data == 100
puts “#{data.time_written}”

I have just inserted a step which adds some additional criteria. This
states if you find data that equals 100 does it happens more than 10
times in one day.

This all works fine. What i want is some kind of nested if statement
thats does the following:

if data == 100
if data happens more than 5 times in one day
print out the results of all the data that equals 100 but highlight
(colour code, italics etc)the data within the results that happens more
than 5 times in a day.

An example of the results might be

100 monday - - - BOLD
100 monday - - - BOLD
100 monday - - - BOLD
100 monday - - - BOLD
100 monday - - - BOLD
100 monday - - - BOLD
100 tuesday - - - NORMAL

Hope this makes sense.

Dear Stuart,

you can output your report as a html document using textile:

using very simple markup styles.

This is how I’d do it: first build an histogram of the data. In this
case
you want to count how many there are of a combination of data and day.
Then print the array checking against the histogram for choosing style:

irb(main):001:0> TimeData = Struct.new :data, :day
=> TimeData
irb(main):002:0> a = []
=> []
irb(main):003:0> 6.times {a << TimeData.new(100, “monday”)}
=> 6
irb(main):004:0> a << TimeData.new(100, “tuesday”)
=> [#, #, #,
#, #, #, #]
irb(main):005:0> h = Hash.new(0)
=> {}
irb(main):007:0> a.inject(h) {|histo,time| h[[time.data, time.day]] +=
1}
=> 1
irb(main):008:0> h
=> {[100, “tuesday”]=>1, [100, “monday”]=>6}
irb(main):009:0> a.each do |time|
irb(main):010:1* if h[[time.data, time.day]] > 5
irb(main):011:2> puts “#{time.data} #{time.day}”
irb(main):012:2> else
irb(main):013:2* puts “#{time.data} #{time.day}”
irb(main):014:2> end
irb(main):015:1> end
100 monday
100 monday
100 monday
100 monday
100 monday
100 monday
100 tuesday

Hope this helps.

Jesus.
