Objective-C Scanner

[korny]

Since I didn't start this one yet, let's push it to 1.2.

Hi! I need this. What do you need to get rolling?

[korny]

More free time ;-)

And example code, lots of crazy syntax examples.

[nathany]

I have a few Objective-C books I may be able to pull examples from.

[josefsalyer]

I have more than few projects to pull code from.

Cool. Checkout the https://github.com/rubychan/coderay-scanner-tests repo.

[josefsalyer]

I forked it and checked it out. Is there a particular git workflow that I
should use? Also, where is a good place to drop sample .h/.m files?

You'll need to create an objective-c folder with some .in.m files, just take a peek at how the other languages do it. I'm pretty sure there is a rake test to do some setup for you, but I don't remember off-hand. Feature branch + pull request would be grande.

[korny]

The easiest way should be to check out the CodeRay repo and just run rake test:scanners. It checks out coderay-scanner-tests automatically then into a subfolder.

I'd like to start working on this one.
Are the guidelines still valid?
Is there any previous work I should be aware of?

[korny]

Yes.

Only what's in this PR, afaik.

[tompave]

Ok, thanks.
I think I'll base my work on the C scanner, as Objective-C is a strict superset of C.

[korny]

Good idea. I guess for some things you need nested states or multiple state variables. Other scanners should give you lots of examples how to approach this, but I found using a new method optimized for each language to be the best way.

[tompave]

Ok, thanks. I'll definitely ask here when I reach that stage.
80% of the work should be about recognizing the object oriented layer, that thankfully has a very precise syntax borrowed from Smalltalk.
I'll also need to consider all tokens starting with 2 capital letters as Class names, as that is the Objective-C convention.
