### 5`` Snip Functions

( snip-width snip) → real?
snip : ( is-a?/c snip% )

The width of a snip in the parent pasteboard.

( snip-height snip) → real?
snip : ( is-a?/c snip% )

The height of a snip in the parent pasteboard.

( snip-min-width snip) → real?
snip : ( is-a?/c snip% )

The minimum width of the snip

( snip-min-height snip) → real?
snip : ( is-a?/c snip% )

The minimum height of the snip.

( snip-parent snip) → ( is-a?/c pasteboard% )
snip : ( is-a?/c snip% )

The pasteboard that contains the snip.

( fold-snip f init-acc snip) → any/c
f : (( is-a?/c snip% ) any/c . -> . any/c )
init-acc : any/c
snip : ( is-a?/c snip% )

Applies f to all snips in the parent of snip, starting with snip.

( for-each-snip f first-snip more ...) → void?
f : (( is-a?/c snip% ) . -> . any/c )
first-snip : ( is-a?/c snip% )
more : list?

Applies the function to each snip in the parent of first-snip, starting with first-snip. If more lists are supplied, they are used for extra arguments to f, just like extra lists provided to for-each.

( map-snip f first-snip more ...) → void?
f : (( is-a?/c snip% ) . -> . any/c )
first-snip : ( is-a?/c snip% )
more : list?

Applies the function to each snip in the parent of first-snip, starting with first-snip, and accumulates the results into a list. If more lists are supplied, they are used for extra arguments to f, just like extra lists provided to map.

( stretchable-width? snip) → boolean?
snip : ( is-a?/c snip% )

True if the snip can be resized in the X dimension.

( stretchable-height? snip) → boolean?
snip : ( is-a?/c snip% )

True if the snip can be resized in the Y dimension.
