@doon Every method in Objective-C goes in pair with plain C function implementing it. self and _cmd are just the first parameters of each implementation, not the reserved keywords.

@hafthor Excellent point, thanks!
Adding ... to macro declaration fixed this issue:

#define weakifySelf(BLOCK...)

Why not git clean -df?
To show what will be removed you can use git clean -ndf.
Also clean-untracked may leave empty directories but git clean removes untracked directories entirely.

You do not need weakSelf here. The block lies on the stack, you do not pass it to anywhere or return from a method. So it is not copied to heap and it does not retain variables. Moreover it will be destroyed when method finishes. Just use self.

@skopp Depending on chosen branching model there may be different cases when we need fast-forward. In the article I show a very simplified one, just for example.

Interesting. Does it work only with github, or it can be used with any git server, e.g. bitbucket?
