futhark <subcommand> options…
Futhark is a data-parallel functional array language. Through various
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
futhark benchcmp FILE_A FILE_B¶
Compares two Futhark benchmarks and reports changes in performance. The files must be formatted in the same manner as a JSON file returned from futhark-bench.
futhark check [-w] PROGRAM¶
Check whether a Futhark program type checks. With
-w, no warnings
futhark check-syntax PROGRAM¶
Check whether a Futhark program is syntactically correct.
futhark datacmp FILE_A FILE_B¶
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.
futhark dataget PROGRAM DATASET¶
Find the test dataset whose description contains
#1) and print it in binary representation to standard
output. This does not work for
futhark defs PROGRAM¶
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.
futhark dev options… PROGRAM¶
A Futhark compiler development command, intentionally undocumented and intended for use in developing the Futhark compiler, not for programmers writing in Futhark.
futhark eval [-f FILE] [-w] <exprs…>¶
Evaluates expressions given as command-line arguments. Optionally
allows a file import using
futhark hash PROGRAM¶
Print a hexadecimal hash of the program AST, including all non-builtin imports. Supposed to be invariant to whitespace changes.
futhark imports PROGRAM¶
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.
futhark query PROGRAM LINE COL¶
Print information about the variable at the given position in the program.
futhark tokens FILE¶
Print the tokens the given Futhark source file; one per line.
futhark-opencl, futhark-c, futhark-python, futhark-pyopencl, futhark-wasm, futhark-wasm-multicore, futhark-ispc, futhark-dataset, futhark-doc, futhark-test, futhark-bench, futhark-run, futhark-repl, futhark-literate
