futhark - a parallel functional array language
futhark <subcommand> options...
Futhark is a data-parallel functional array language. Through various subcommands, the futhark tool provides facilities for compiling, developing, or analysing Futhark programs. Most subcommands are documented in their own manpage. For example, futhark opencl is documented as futhark-opencl. The remaining subcommands are documented below.
Compare two JSON files produced by the --json option of futhark-bench. The results show speedup of the latter file compared to the former.
Check whether a Futhark program type checks. With -w, no warnings are printed. With --Werror, warnings are treated as errors.
Check whether a Futhark program is syntactically correct.
Check whether the two files contain the same Futhark values. The files must be formatted using the general Futhark data format that is used by all other executable and tools (such as futhark-dataset). All discrepancies will be reported. This is in contrast to futhark-test, which only reports the first one.
Find the test dataset whose description contains DATASET (e.g. #1) and print it in binary representation to standard output. This does not work for script datasets.
Print names and locations of every top-level definition in the program (including top levels of modules), one per line. The program need not be type-correct, but it must not contain syntax errors.
A Futhark compiler development command, intentionally undocumented and intended for use in developing the Futhark compiler, not for programmers writing in Futhark.
Evaluates expressions given as command-line arguments. Optionally allows a file import using -f.
Print a hexadecimal hash of the program AST, including all non-builtin imports. Supposed to be invariant to whitespace changes.
Print all non-builtin imported Futhark files to stdout, one per line.
Run an LSP (Language Server Protocol) server for Futhark that communicates on standard input. There is no reason to run this by hand. It is used by LSP clients to provide editor features.
Print information about the variable at the given position in the program.
Expresses gratitude.
Print the tokens the given Futhark source file; one per line.
