Ruby-Notes

Just a way to keep track of some notes and snippets

One liner code to open and write to a file

File.open('test.txt', 'w') {|f| f.write(doc) }
puts "yeah, it is done"

Assert Definition

assert will terminate the program (usually with a message quoting the assert statement) if its argument turns out to be false. it's commonly used during debugging to make the program fail more obviously if an unexpected condition occurs.

for example:

assert(length >= 0);  // die if length is negative.

Objects

Get the mothods of any object by using ".methods"

self.methods

#or

x = []

x.methods
