Re: [swift-users] Swift creduce

[Huon Wilson via swift-users]

Sorry, I was inaccurate: there’s also some syntactic constructs that don’t get 
minimized as much as they could because they’re too “complicated". The most 
common one I’ve noticed is instance variable without defaults: creduce doesn’t 
seem to be able to coordinate removing both declaration and the later 
initialization at the same time, and it’s invalid to remove either one 
individually.

However, I’ve found doing one run of creduce, followed by some hand editing to 
tease out any those sort of dependencies remaining (including just replacing 
function bodies with fatalError()), lets a second run finish the job. 
Alternatively, after the first run, the code is often small enough that one can 
just do the rest by hand without a second run.

Wow, very cool. I'm not going to lie, creduce really does have some magic going 
on. :)

Thanks everyone, I'll go back to creduce and see how it handles Swift.

Re: [swift-users] Swift creduce

[Huon Wilson via swift-users]

No; Swift just looks C-like enough that many of the various heuristics creduce 
has still work reasonably efficiently. Unless one's “good or not” script is 
doing something weird, the areas where creduce doesn’t understand Swift are 
ignored, because the compiler output is not going to match what the script is 
checking for.

The main downside of it not understanding Swift is that it is likely to be 
slower than on C, since it’ll be wasting its time on some mutations that will 
very very rarely be interesting.

Ok, that's unexpected. Does creduce know about Swift now?

Huon noticed that creduce actually works pretty well with Swift as-is. I’ve 
been using it without any issues.

[swift-users] Swift creduce

[Doug Hill via swift-users]

Is there a version of 'creduce' for Swift?

I did some basic googling and didn't find anything, so I thought I'd ask here.

Thanks.
