Project 2: getting a feel for ruby

Due: Oct 1 by 11:59pm

Overview

To really get a comparitive feel for these two languages, I want you to implement the same project you just did in python, but this time do it in Ruby. This will give you an idea about how the two languages handle simple text processing: something that both languages do pretty well.

Assignment

Write a ruby program that will take its first command line argument as a file name. Open that file and produce the following output from the file. Each item should be formatted nicely, labeled (so a casual reader knows which number is the number of lines, the number of words and so on.) and on its own line in the output. The output should contain all of the following:

• The number of lines of text in the file
• The number of words in the file (lets define "word" as any item, including numbers, surrounded by whitespace on either side)
• The number of characters in the file.
• The number of lines beginning with the text "error:"
• The percentage of all lines which are error lines.
• The number of groups of error lines. If five lines beginning with the "error:" text are concecutive preceeded and followed by lines beginning with other text, it is considered one group of error text.

If your program in ruby is longer than about a page, you are probably making this assignment more complicated than it needs to be. (Hint, it really helps to read your book on this one. I already decided what the first assignments should be before I read the ruby book)
