FException
This repository offers examples for possible exception handling in Fortran.
The folder examples contains *_fxy.f90 files with the suggested
syntax for different scenarios. Each of the files has a corresponding *.f90
file with a working implementation in Fortran 2008. This demonstrates, that
the features proposed here are possible in Fortran already, the proposed
new syntax only serves the purpose to spare a significant amount of boiler
plate code.
Building
In order to build the Fortran examples, use the usual CMake workflow:
mkdir build cd build cmake .. make
The example executables will be in the ./examples folder in the build
directory.
Related projects
The ErrorFx library (which this project emerged from) contains a working implementation of the presented concepts using Fypp macros. Since it is preprocessor based, it has a few limitations (e.g. completness of the exception catching can only be checked at run time, not at compile time), but it already offers out of the box exception handling without the need for writing a lot of boiler plate code.
If you are interested in the discussion about the presented concepts (and their possible inclusion in a future Fortran standard), join us in the corresponding issue at the J3 Fortran github site.
