# # Hello!
2+
#
3+
# This lab teaches basic Ruby function syntax.
4+
#
5+
# ## Open a terminal in this directory
6+
#
7+
# cd 00_hello
8+
#
9+
# This directory is the starting point for this exercise. It contains a spec file and you'll be adding a ruby file to (eventually) make the specs pass.
10+
#
11+
# ## Run the test
12+
#
13+
# rake
14+
#
15+
# ## Watch it fail
16+
#
17+
# You should see an error. **Don't get scared!** Try to read it and figure out what the computer wants to tell you. Somewhere on the first line it should say something like
18+
#
19+
# no such file to load -- test-first-teaching/hello/hello (LoadError)
20+
#
21+
# That means that it is looking for a file called `hello.rb` and can't find it.
22+
#
23+
# ## Create hello.rb
24+
#
25+
# Open up `hello.rb` in a text editor. Save it. Run the test again.
26+
#
27+
# rake
28+
#
29+
# ## Watch it fail
30+
#
31+
# Now you should see an error like this:
32+
#
33+
# the hello function
34+
# says hello (FAILED - 1)
35+
#
36+
# Failures:
37+
#
38+
# 1) the hello function says hello
39+
# Failure/Error: hello.should == "Hello!"
40+
# NameError:
41+
# undefined local variable or method `hello' for #<RSpec::Core::ExampleGroup::Nested_1:0x000001009b8808>
42+
# # ./hello/hello_spec.rb:5:in `block (2 levels) in <top (required)>'
43+
#
44+
# ## Create the hello function
45+
#
46+
# Fix this by opening `hello.rb` and creating an empty function:
47+
#
48+
# def hello
49+
# end
50+
#
51+
# Save it. Run the test again.
52+
#
53+
# ## Watch it fail
54+
#
55+
# Now you should see an error like this:
56+
#

58+
# says hello (FAILED - 1)
59+
#

62+
# 1) the hello function says hello
63+

# got: nil (using ==)
66+
# # ./hello/hello_spec.rb:5:in `block (2 levels) in <top (required)>'
67+
#
68+
# This means that while it found the file, and it found the function, it's not returning anything! ("nil" is the Ruby way of saying "not anything".)
69+
#
70+
# ## Make it return something
71+
#
72+
# Inside the "hello" function, put a single line containing a string that is *not* "Hello!". (Here we are simulating you making an honest mistake, so we can see what the error message looks like.)
73+
#
74+
# def hello
75+
# "whuh?"
