# futhark-fmt(1)

format Futhark programs

## NAME

futhark-fmt - format Futhark programs

## SYNOPSIS

futhark fmt \[options...\] \[FILES\]

## DESCRIPTION

Reformat the given Futhark programs. If no files are provided, read Futhark program on stdin and produce formatted output on stdout. If stdout is a terminal, the output will be syntax highlighted.

In contrast to many other automatic formatters, the formatting is somewhat sensitive to the formatting of the input program. In particular, single-line expressions will usually be kept on a single line, even if they are very long. To force **futhark fmt** to break these, insert a linebreak at an arbitrary location.

## OPTIONS

- **--check**

  Check if the given files are correctly formatted, and if not, terminate with an error message and a nonzero exit code.

- **-h**

  Print help text to standard output and exit.

- **-V**

  Print version information on standard output and exit.
