Making separate File

John Micheal

6/10/2008 2:22:00 PM

Hello,
The given two classes (TestClass1 and TestClass2) are in a single ruby
code. I want a code that separate both classes and save them into 2
diffrent ruby files.

E.g

Orginal code "test.rb" (contains the classes)
after executing

one file for 1 class "class1.rb"
second file for second class "class2.rb"
and so on...

I would be very thankful to you dear
-------------------------

class TestClass1

def method1(a,b)
sum = a + b
puts sum
end

def method2(*c)
l = c.length
puts l
end
end
--------------
class TestClass2

def method1(a,b)
sum = a + b
puts sum
end

def method2(*c)
l = c.length
puts l
end
end

For what exactly? I mean, opening two files in an editor and copy +
pasting the code there can't be that hard, can it?

Cheers

Without opening them. It should seprate the code based on "class"
keyword and storing it in other file using ruby code.

Michel,

supposing that the original code is in "sourcefile", and that there is no text in between
the classes, you can use something like this:

text=IO.readlines(sourcefile)
classes=text.split(/(?=class )/).delete_if{|text| /^class/.match(text)==nil}
classes.each_with_index{|c_text,i|
f=File.new("class_file_" + i.to_s + '.rb',"w")
f.puts c_text
f.close
}

Best regards,

Axel

Michel,

sorry, that was my fault.
You must change the line with IO.readlines to

text=IO.readlines(sourcefile).to_s

Otherwise, text is an Array, but with to_s, it is converted to a String.
And that's what the Regular Expression needs.

Best regards,

Axel

Or just do

test = IO.read(sourcefile)

Cheers
