This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
$ stack install hfmt
$ cabal install hfmt
Check all Haskell source under the current directory:
Overwrite files with formatting suggestions:
λ hfmt --help hfmt - format Haskell programs Usage: hfmt [-d|--print-diffs] [FILE] Reformats Haskell source files by applying HLint, hindent, and stylish-haskell. Available options: -h,--help Show this help text -d,--print-diffs If a file's formatting is different, print a diff. -s,--print-sources If a file's formatting is different, print its source. -l,--print-paths If a file's formatting is different, print its path. -w,--write-sources If a file's formatting is different, overwrite it. FILE Explicit paths to process. - A single '-' will process standard input. - Files will be processed directly. - Directories will be recursively searched for source files to process. - .cabal files will be parsed and all specified source directories and files processed. - If no paths are given, the current directory will be searched for .cabal files to process, if none are found the current directory will be recursively searched for source files to process. Exit Codes: 0 = No error 1 = Encountered I/O or other operational error 2 = Failed to parse a source code file 3 = Source code was parsed but cannot be formatted properly 4 = Formatted code differs from existing source (--print-diffs only)
