gfort2py - Release: v2.4.2

Add support for new platforms
Switch compile function to be mostly keyword only arguments
Various packages needed for building have had their minimum version bumped
mod data can now be exported as JSON

- Python

gfort2py - Release: v2.4.1

Add support for callback functions
Allows access to bind(C) variables and functions

- Python
Published by rjfarmer about 2 years ago

gfort2py - Release: v2.4.0

Adds the ability to load Fortran code from either a string or file. This avoids the user needing to have to compile and build a shared library themselves.
Update to support Python 3.12
Update to support gfortran 13

- Python

gfort2py - Release: v2.3.0

Initial support for quad precision variables
Switch from pyparsing to cpyparsing for faster loading of the mod files
Add caching option of mod files for faster startups
Fix bug in optional character dummy arguments
Fix bug when we need to re-resolve runtime arguments

- Python

gfort2py - Release: v2.2.1

Fix issue with assumed shape character arrays

- Python
Published by rjfarmer over 2 years ago

gfort2py - Release: v2.2.0

Add support for complex parameter arrays

Expand the kinds supported for integers, reals, and complex numbers

Allow functions to return an array as a result

- Python

gfort2py - Release: v2.1.0

Fixes bugs in logical parameters

Enables support for runtime-defined explicit arrays where the dimension requires evaluating a unary op i.e dimension(n+1) or dimension((n*2)+1)

Be more careful about using np.double for double-precision variables

After many years (and several complete re-writes) I am pleased to announce the release gfort2py v2.0.0. gfort2py is a Python library enabling the calling of Fortran code from Python. The main aim of this library is to make calling the Fortran code as easy as possible by minimising the number of changes to the Fortran code. All that is required is to have your code in a module and compiled as a shared library. No annotations or other changes needed.

Source code is available at https://github.com/rjfarmer/gfort2py

Gfort2py works with python >=3.7 and gfortran >=8. Note that there are many API breakages with the gfort2py 1.. series. Please refer to the README at https://github.com/rjfarmer/gfort2py/blob/main/README.md for examples of the new features.

Gfort2py supports many modern (and old) Fortran features including:

Scalars (ints, reals, logicals, characters) Arrays of (ints, reals, logicals, characters): explicit, assumed shape, assumed size, and allocatable arrays. Derived types including scalars and arrays. Explicit arrays of derived types (assumed shape are not yet supported) Allocatable strings (partial support) Calling functions and subroutines.

More features are planned to be added over time.

Installation via pip: python -m pip install --upgrade gfort2py

For those that want to get involved: Improvements to the test suite to include untested or new Fortran features (and Python code to test those features, even if it doesn’t yet work) is the most helpful. Otherwise, bug reports on broken features are also helpful.

gfort2py - Speed up load times

We now defer initializing most objects till they are needed, which should help start up times with large modules. Parsemod now uses dicts instead of lists thus its file version number has been bumped from 1 -> 2 Arrays in dt's are know mostly viewable without crashing, though setting them can still be an issue
