Here is my code :
File.open("#{dir}/input.txt",‘r’) do |file|
file.each_line do |line|
if /^\s+([A-Z][a-z]+)\s*$/ === line
@line_number = file.lineno
break
end
end
end
#puts fruits_line_number
@data_array = []
@header_array = []
@fruit_and_kinds_array = []
@csv_array = []
##below I am tying to line number to a value. But #each_line method
starts ##reading lines from the beginning, instead of starting from the
line ##number I am trying to set.
File.open("#{dir}/input.txt",‘r’) do |file|
p file.lineno = @line_number
file.each_line do |line|
case line
# This will find the parent fruits/vegetables
when /^\s+([A-Z][a-z]+)\s*$/
@parent_fruit = line.strip
# This will match sub classes of the parent fruit/vegetable class
when /^([A-Z][a-z]+)\s?/?(\s?[A-Z][a-z]+\s?/?)\s$/
@fruit_and_kinds_array.clear unless @fruit_and_kinds_array.empty?
@fruit_and_kinds_array << line.strip
when /^\s*$/m,/\A[^@\s][email protected]([^@\s]+.)+[^@\s]+\z/
# blank line or line having email addresses, so do nothing
# This will match all the header names of the actual data
when /\b(^variety|kg|pp)\b/i
@header_array.clear unless @header_array.empty?
@header_array.concat line.strip.split
else
# this will collect all the actual fruits/vegetables data
puts @data_array << line.strip.unpack(“A25A12A15A6A*”)
@csv_array += @fruit_and_kinds_array + @header_array +
@data_array[0…-2] + @data_array[-1].split
@data_array.clear
puts @csv_array
end
end
end
How can I do, what I am trying to achieve ?
