fyyp 1.0 to 2.0.1

[jacopo-chevallard]

Hi Balint, I'm trying to migrate to the version 2.0.1 of fypp, but I'm having troubles in adapting the following expression, which was working with fypp 1.0, to the new version of fypp

#:for dim, shape, var in shapes
  #:set dims = ''.join([ 'dims(' + str(i+1) + '),' for i in range(int(dim)) ])[0:-1]
#:endfor

any suggestion?

Hi Jacopo :smile:

Could you please create a self-containing minimal example demonstrating the failure of fypp for your case? I've just tried

#:set shapes = [(3, (1, 2, 3), "a"), (2, (9, 4), "b")]
#:for dim, shape, var in shapes
  #:set dims = ''.join([ 'dims(' + str(i+1) + '),' for i in range(int(dim)) ])[0:-1]
DIMS: ${dims}$  
#:endfor

with fypp 2.0.1 (together with Python 2.7.6 and Python 3.4.3) and obtained the expected result

DIMS: dims(1),dims(2),dims(3)  
DIMS: dims(1),dims(2)

Do you get something else?

Hi Balint, thanks a lot for the quick answer ! 😄 I indeed found the problem: I was using the name str to define a fypp variable later on, and this was producing the error message

lib_NDinterpolation_test.fpp:113: error: exception occured when setting variable(s) 'dims' to '''.join([ 'dims(' + str(i+1) + '),' for i in range(int(dim)) ])[0:-1]' [FyppFatalError]
error: 'str' object is not callable [TypeError]

In fypp 1.0 it runs without problems, while in this version it raised the error above!

closing, as it is solved by avoiding defining a variable called str
