DebugPbind : Pbind

DebugPbind works just like Pbind, but outputs a wealth of debugging information for each .next call:

- The input event

- For each key/value pair:

- The key (name)

- The event as it has been modified thus far

- The stream value to be placed into the event

- The resulting event

Very useful for identifying Pbind execution problems, especially early termination due to a child stream returning nil unexpectedly.

(

p = DebugPbind(

\key1, Pwhite(0.0, 1.0, 2),

\key2, Pseries(15, 1, inf)

).asStream;

while { p.next(()).notNil };

)
