gopaw embarques the core of a Python-2.7 to replace the COMIS FORTRAN interpreter.
WARNING, WARNING, WARNING: we do not bring the whole Python library, but only what is needed to define a function and do some maths in it.
You have an example of usage in the examples/py_root directory by looking at the pawex10.kumac script:
MACRO PAWEX10 1=100 ************************************************************************** * PAW TUTORIAL EXAMPLE 10 * * Calculate and plot (BOX option) Mandel distribution * ************************************************************************** Exec ALLDEF fun2 10 mandel.py [1] -2.4 .8 [1] -1.2 1.2 ' ' fortran/file 66 mandel.ps metafile 66 -111 hi/pl 10 BOX close 66 RETURN
with mandel.py being:
# Copyright (C) 2018, Guy Barrand. All rights reserved.
# See the file gopaw.license for terms.
def mandel(XP,YP):
NMAX = 30
X = XP
Y = YP
XX = 0
YY = 0
for N in range(1,NMAX+1) : #[1,NMAX]
TT = XX*XX-YY*YY+X
YY = 2.0*XX*YY+Y
XX = TT
if 4.0 < (XX*XX+YY*YY) :
break
#print XP,YP
#print N
return (1.0*N)/(1.0*NMAX)
The way of doing is the same than in the original CERN-PAW example that worked with the FORTRAN COMIS interpreter. See original examples/f77_hbook/pawex10.kumac and mandel.f at end. Note that pictures in the Gallery section had been done with the Python versions of all the pawex[1,24].kumac found in examples/py_root. In py_root, the _root comes from the fact that manipulation of .hbook files had been replaced with manipulation of .root files.
To run the pawex10.kumac Python version:
UNIX> cd <some_path>/examples/py_root # have a local copy.
UNIX> <start gopaw>
on Windows:
DOS> cd <some_path>\examples\py_root
DOS> <start gopaw>
GOPAW> exec pawex10
