Text/console falling-block tetromino game written in Modern Fortran. It has diverged and been enhanced considerably from L. Bobberman's original demo.

• user-configurable playfield size
• Logs pieces played to tetran.log so you can recreate memorable games.
• uniform random game piece generation.
• clean, modern Fortran 2008 syntax
• Ncurses used for display, called directly from Fortran code (this is a blocker for native Windows).

Tetran works on Mac, Linux, Cygwin and Windows Subsystem for Linux. Any modern Fortran compiler (including Flang with CMake >= 3.10) should work.

• Linux / WSL: apt install gfortran libncurses-dev
• Mac: brew install gcc ncurses
• Cygwin: setup-x86_64.exe -P libncurses-devel cmake make gcc-gfortran

cd bin
cmake ..
make
make test

Optional: specify a compiler by setting FC=.

• Intel: FC=ifort cmake ..
• Flang: FC=flang cmake ..
• PGI: FC=pgf95 cmake ..

./tetran

adjust cadence of falling blocks with -d option, including decimal point:

./tetran -d 1.2

Higher number => more difficult. Must include decimal point.

Debug logging is enabled by:

./tetran --debug

Other "secret" cheat keys exist! You can also use arrow keys.

unlike some games, block distribution is uniformly random as confirmed by:

./blockrand

using time ./blockrand 100000000 relative normalized execution times were:

-O3:

GNU   1.00 (fastest normalized)
Flang 1.90
PGI:  1.82
ifort 8.22

Tested with:

• Intel Haswell laptop CPU
• Flang 5.0
• Gfortran 7.3
• Intel Fortran 2019
• PGI 2018

So Intel Fortran takes over 5 times longer than Gfortran at this simple single-thread benchmark.
