Slurp/barf sexps

[thomasheartman]

Through smartparens, Emacs lets you slurp/barf expressions into the current enclosing delimiter. In short it allows you to do extend the selection of the current expression by either moving the delimiter to the next expression, by retracting it by one expression (in either direction).

In short, with the cursor in the first set of parens:

(some-fn x)(g y)

you can slurp the next one, which would yield

(some-fn x (g y))

While this is especially useful in lisps, I've also often found use for it in C-like languages.
