futhark-py [-V] [-o outfile] infile


futhark-py translates a Futhark program to sequential Python code.

The resulting program will read the arguments to the main function from standard input and print its return value on standard output. The arguments are read and printed in Futhark syntax, just like futharki(1).

The generated code is very slow, likely too much to be useful. It is more interesting to use this command’s big brother, futhark-pyopencl.


-o outfile Where to write the resulting binary. By default, if the source program is named ‘foo.fut’, the binary will be named ‘foo’.
-v verbose Enable debugging output. If compilation fails due to a compiler error, the result of the last successful compiler step will be printed to standard error.
--library Instead of compiling to an executable program, generate a Python module that can be ported by other Python code. The module will contain a class of the same name as the Futhark source file with .fut removed. Objects of the class define one method per entry point in the Futhark program, with matching parameters and return value.
-I dir, --import dir
 Add directory to the list of directories searched when locating imported files.
-h Print help text to standard output and exit.
-V Print version information on standard output and exit.
