A work in progress modern fortran compiler written entirely in modern fortran.
Currently this compiler targets 16 bit URCL, but more backends will likely be added in the future.
This compiler is intended to be installed using fpm (https://fpm.fortran-lang.org/install/index.html#install). From the root of the project, run fpm install --profile release to install the compiler. The compiler can then be executed by running urclfortran.
The compile.sh shell script is provided for developers and those who prefer a manual installation. This script is intended primarily for debugging purposes (to enable testing with ifort).
urclfortran follows a rather typical syntax for command line arguments. Use -o (filename) to specify output file name. Use -c to disable linking.
urclfortran relies on urcl-ld for linking urcl fles (https://github.com/Verlio-H/urcl-ld.git). The environment variable LIBFORT_PATH must be set to the global path of the libfortran directory for linking to work.
urclfortran currently performs no preprocessing. In other words, the file extension is ignored and .F90 is equivalent to .f90.
Tests can be ran using bats (https://github.com/bats-core/bats-core) with the test.bats script (must be ran from root of repository). These tests assume the presence of bash environment.
Currently, this compiler supports a very very limited set of functionality. Don't expect most fortran code to be functional. An idea of the current supported set of features can be found by looking at the tests. In the future, support tables will likely be made.
