-pdp_guile starts a scheme interpreter is started on pd's standard io.
-there is a simple send/receive interface in pd to communicate with the
-running scheme interpreter trough an input and output queue. pd can
-send messages, including pdp packets, to guile with the [ss tag] object.
-
-guile can read using the (in) fuction, which returs a two element list:
-the tag and the object (a float, a symbol, a list or a packet) i.e. if
-you connect a [pdp_v4l] object to a [ss some-tag-symbol] object and bang
-the v4l object, you can retreive the packet in guile using something
-like this:
-
-(in)
-=> (some-tag-symbol #<pdp 0 image/YCrCb/320x240>)
-
-(in) retreives the oldest message from the input queue. if there are no
-more messages, (in) returns #f
-
-guile can write using the (out tag object) function, which will send the
-object to a [r tag] pd reciever. i.e. if you connect a
-[r some-tag-symbol] object to a [pdp_xv] object, you can display a
-packet (here contained in variable p) by doing:
-
-(out 'some-tag-symbol p)
-
-
-guile is connected to pdp's forth scripting language (pdp's "rpn
-calculator") using the (forth stack wordlist) statement. it returns the
-processed stack. i.e.:
-
-(define p0 (make-pdp 'image/grey/320x240))
-(define p1 (make-pdp 'image/grey/320x240))
-(forth `(,p0 ,p1) '(add))
-=> (#<pdp 2 image/grey/320x240>)
-
-
-see pdp_guile.scm and pdp_guile.pd for an example of how pdp_guile
-could be used.
-
-this is mainly for experimental interactive work and testing pdp's forth
-scripting. there's no documentation, apart from this file, the example
-and the source code. if you like to have more info, just drop me a
-line.
-
-if you want to write externals in scheme, this is probably not for you.
-
-requirements: libguile 1.6.x
-
-
-enjoy,
