battleships in Fotran

Fortran 2008 Battleship game, original code from https://github.com/surftheseawing/battleships. We observed the original code could be modernized to work on all modern Fortran compilers.

The changes we did include:

• module level implicit none
• use format i0
• use iso_fortran_env
• use read(..., iostat=) to handle unexpected input
• use escape characters instead of system calls to clear screen
• use standrd sleep() implementation we created in scivision/fortran-sleep
• break code up into source files for ease of devel

Tested on compilers including:

• GCC gfortran
• Intel oneAPI

Build

CMake or FPM (Fortran Package Manager) can quickly build Battleships:

cmake -B build
cmake --build build

build/battleships  # runs game

OR

fpm run
