Fix typos in README usage section

[rvictorino]

• Trailing «r» missing for «Generator»:

SpellGenerator::Generato.new.generate #=> "Symptomatic punch"

• Trailing «r» missing for «Generator»; missing comma between arguments if given output is what's expected:

SpellGenerator::Generato.new.self_generate('Random' 'Fire') #=> "Random Fire"

Fixing this does not require to write code (but requires to execute it to validate solution !)

This would be a great first issue as well!!
Thanks @rvictorino !!

Closing the issue since it was fixed here.

@rvictorino
Thanks for opening the issue😇!!

@K-Sato1995 both missing «r» have been fixed by the linked PR (#10 ).

However, executing :

SpellGenerator::Generator.new.self_generate('Random' 'Fire')

Outputs RandomFire, not Random Fire (notice the missing space between words).

I'm not a Ruby dev, so I may be missing some key point or syntactic sugar but adding a comma between both strings seems to help 😄

I guess, since this issues has been partially fixed, it would be logical to reopen it but maybe you would prefer that I open a new one focusing on the comma thing ?

Hi! Thanks for this 😊!!
In ruby, you need to put , between each argument. Otherwise, Ruby's interpreter recognizes it as one string like in the example below.

# This method is expecting to get 2 arguments when it's called. 
def test(a,b)
  p "#{a} and #{b}" 
end

test('string1', 'string2') #=> "string1 and string2" # Got 2 arguments as expected.
test('string1'  'string2') #=> wrong number of arguments (given 1, expected 2) # Ruby treat it as if only one string was passed.

That said, it is wired it didn't raise any error and output RandomFire. I specified to raise an error when only one value is passed to the method here.

I just created examples/spells.rb. Can you check if you can reproduce the same case using the example??

You can run the code by following the steps below in your terminal.

cd spell_generator // move to this project's directory
ruby examples/spells.rb

Hi, it's me, again !

yeah, I knew I saw something about checking number of arguments in the source code; that's what bugged me.

I can reproduce !
In the example spells file, there is a comma between arguments, so it works !

When I remove the comma, I get RandomFire (no space).

To sum things up, here are the code / outputs pairs I tested:

SpellGenerator::Generator.new.self_generate('Random', 'Fire') #=> Random Fire
SpellGenerator::Generator.new.self_generate('RandomFire') #=> RandomFire
SpellGenerator::Generator.new.self_generate('Random' 'Fire') #=> RandomFire

• First one is what's expected
• Second one is just one argument. Shouldn't it fire something / not work?
• Same for the third line, except the only argument is split in two strings.

So two things:

• As stated in this issue, README needs to be updated to reflect a working usage with two arguments: add a comma between Random and Fire.
• There might be some unexpected behavior when this method is used with only one argument: Should I create a new issue to explain it separately?

Thanks again for those great explanations about ruby @K-Sato1995 !! 🤓 😃

Hi @rvictorino !
I really appreciate your thorough review of this project!!
It's always good to have a more experienced programmer like yourself looking over a project👏.

As stated in this issue, README needs to be updated to reflect a working usage with two arguments: add a comma between Random and Fire.

Yes for sure! The part about #self_generate in README.md is definitely not correct rn🙇🏼‍♀️.

There might be some unexpected behavior when this method is used with only one argument: Should I create a new issue to explain it separately?

Originally the expected behavior is to raise the original SpellGeneratorError when only one argument is passed to the method.
I would really appreciate if you open issues for those problems respectively🙇🏼‍♀️.

Thanks again!!! I truly appreciate your cooperation🥇!
