class:: Pnsym
summary:: use a pattern of symbols to embed Pdefns
categories:: JITLib>Patterns, Live Coding
related:: Classes/Pdefn

description::
for event patterns see link::Classes/Psym::. Overview: link::Overviews/JITLib::.

ClassMethods::

method::new

argument::pattern
a pattern that returns symbols or characters. Arrays are converted to parallel patterns ( link::Classes/Ptuple:: ).

argument::dict
the dictionary to be used for lookup. By default, this is code::Pdefn.all::, so one can embed Pdefns by name.

InstanceMethods::

method::dict
set the dictionary to be used.

Examples::

code::
(
// load a synthdef
s.boot;
SynthDef("gpdef",
	{ arg out=0, freq=440, sustain=0.05, amp=0.1, pan;
		var env;
		env = EnvGen.kr(Env.perc(0.01, sustain), doneAction: Done.freeSelf) * amp;
		Out.ar(out, Pan2.ar(SinOsc.ar(freq, 0, env), pan))
	}).add;
)

Pdefn(\x, Pn(1, 3));
Pdefn(\y, Prand([5, 9, 1], 2));
Pdefn(\z, Pdefn(\y) * 2);

(
Pdef(\play,
	Pbind(
		\instrument, \gpdef,
		\harmonic, Pnsym(Pseq([\x, \x, Prand([\x, \y]), [\z, \y], \y], inf)).trace,
		\dur, 0.2, \note, 10
	)
).play;
)

// change root pattern:
Pdefn(\x, Pn(2, 3));
Pdefn(\x, Pseq([1, 3, 1, 2, 1, 4, 5]));
Pdefn(\x, Pseq([1, 3, 1, 2, [1, 3], 4, 5]));
