Not sure this is working for me. When (load)ing the following program: [Note: github is stripping the indentation in the source below] ` def main: print("Hello world!")
` it generates the following output: compilation_error: compilation error fortran_code_path /home/grassy/fy/src/tst01/tst01/pycache/fycache/gfortran/debug/hello.f90 compilation_error hello.f90:9:1:

suspect paths become screwed:

Dear Nicolas,
I am not able to understand which Fortran standard(s) Fython supports.
I am developing only in modern idioms (2003 and 2008), so before trying Fyghon I would like to know if Fython support things like abstract type and coarrays.
Thank you very much.
Dear Nicolas,
Great project, my best compliments :clap:
I have already sent a replay on your google clf thread. Here have a question about varisble kind definition:
which are the Fortran kinds that Fython supports?
E.g. if I have a Fortran module defining a math library supporting 32 and 64 bit (like) floats by means of select_real_kind Fortran built-in, Fython (importing this Fortran module) can handle (distinguish) the two kinds?
Thank you very much for sharing your great work.
My best regards.
Why hybrid language, not Python with type annotations? E.g. like Cython, numba, pythran?
remove parenthesis from print
