Hallo,

the [list]-abs collection of abstractions using [list] from pd-0.39 to do various list operations is now in CVS at http://pure-data.sf.net as well, directory "abstractions/footils/list-abs". Proper help files for all abstractions are included.

There are some new additions, so here's the updated README:

list-abs --------

These are abstractions implementing common list operations. Included are in alphabetical order:

last-x.pd

get a list containing the last x atoms received.

list-accum.pd

sum all floats in a list.

list-demux.pd

route lists to different outlets (like demux in zexy). Not an abstraction, just a patch illustrating the idiom.

list-drip.pd

serialize a list automatically (like drip in zexy).

list-drip2.pd

serialize two lists in sync as long as first list lasts.

list-dripslow.pd

serialize a list on demand: each bang will output the next element.

list-inter.pd

element-wise linear interpolation between two (float) lists. list-inter-example-gem.pd shows a more complicated usage example, but requires gem for visualisation.

list-len.pd

calculate length of a list.

list-makefilename.pd

apply [makefilename] on list elements, if they are symbols.

list-math.pd

apply [expr OP] with OP in (+,-,*,/) on list elements, if they are floats.

list-minmax.pd

find minimum and maximum float in a list.

list-rev.pd

reverse a list.

list-rot.pd

rotate a list (move X elements from front to back)

sroute.pd

a settable [route] object for a single selector.

take-two.pd

take a list as input and print all combinations of length two without repetition.

triple-scale.pd

this actually is not using [list]: Interpolate between two (x,y,z)-points. Also see [list-inter], which is more powerful.

Have fun.

Ciao
