example.py
from pipen import Proc, Pipen, ProcGroup

class A(Proc):
"""Process A"""
input = "a"

class B(Proc):
"""Process B"""
requires = A
input = "b"
plugin_opts = {"diagram_hide": True}

class PG(ProcGroup):
"""Process Group"""
@ProcGroup.add_proc
def c(self):
"""Process C"""
class C(Proc):
input = "c"

return C

@ProcGroup.add_proc
def c1(self):
"""Process C1"""
class C1(Proc):
requires = self.c
input = "c1"
plugin_opts = {"diagram_hide": True}

return C1

@ProcGroup.add_proc
def d(self):
"""Process D"""
class D(Proc):
input = "d"
requires = self.c1

return D

pg = PG()
pg.c.requires = B

class E(Proc):
"""Process E"""
input = "e1,e2"
requires = pg.d, A

class F(Proc):
"""Process F"""
input = "f"
requires = E

Pipen("MyPipeline").set_start(A).run()
