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
