futharki [infile]


When run with no options, start an interactive futharki session. This will let you interactively enter expressions which are then immediately interpreted. You cannot enter function definitions and the like directly, but you can load Futhark source files using the :load command. Use the :help command to see a list of commands. All commands are prefixed with a colon.

When futharki is run with a Futhark program as the command line option, the program is executed by evaluating the main function, and the result printed on standard output. The parameters to main are read from standard input.

Futharki will run the standard Futhark optimisation pipeline before execution, but the interpreter is still very slow.


-e NAME Run the given entry point instead of main.
-h Print help text to standard output and exit.
-V Print version information on standard output and exit.


Input editing is not yet implemented; we recommend running futharki via rlwrap(1).
