Lua missions (AKA Lua Koans) - Learn Lua while programming

[kikito]

I wasn't sure about putting this on the projects forum, since it's really only tangentially related with LÖVE, so I'm putting it here.

I've created a Lua Koans project. It's called Lua missions. It's here:

https://github.com/kikito/lua_missions

What are Koans?

Basically, they are tests (functions) that fail - at least initially. You have to fix them. In the process of fixing them, you learn a tiny bit of a language. It starts with the very basic and gradually moves up.

Yesterday I presented these to some people and they were quickly hooked up - they didn't want to leave the keyboard when time run out!

Disclaimer: This is not a finished thing, I'm aware that not the whole PiL is covered. (But a significant chunk already is). Feedback of any kind is encouraged and appreciated (as well as pull requests and forks).

Regards!

Looks neat! Though I think you missed swapping a few instances of Ruby to Lua in the readme:

nil is covered in nil.rb

Each mission builds up your knowledge of Ruby and builds upon itself.

If you do not have Ruby setup, please visit www.lua.org/download.html for operating specific instructions.

Awesome. But yeah, I don't install ruby from lua.org.

Thanks for the feedback!

I've just fixed this.

READMEs are my weak point.

You should really post this to the Lua mailing list.

Yeah, the thought has crossed my mind. Maybe tonight. I spent the last week preparing it and a small activity for a group I'm in, and now I've got a considerable backlog. But yeah. I have to get in touch with those people at some point.

EDIT - Sent.

Awesome. I'll be using those.

Mumon Ekai would disagree. But then, he probably won't. Zen is confusing. (But then it isn't)

string is using the # table operator before it is taught. strings.lua:54,59

also, test_numbers_must_be_converted_to_strings_before_concatenation at strings.lua:76. I don't know this to be true. Seems you can just concat numbers in Lua.

strings.lua:105 should be string.upper(str)

[kikito]

I've fixed those issues in string.lua

Thanks!

I think exercises.lua needs a fizzbuzz http://imranontech.com/2007/01/24/using ... ok-coding/
