# HLint configuration file # https://github.com/ndmitchell/hlint ########################## # This file contains a template configuration file, which is typically # placed as .hlint.yaml in the root of your project # Specify additional command line arguments # # - arguments: [--color, --cpp-simple, -XQuasiQuotes] # Control which extensions/flags/modules/functions can be used # # - extensions: # - default: false # all extension are banned by default # - name: [PatternGuards, ViewPatterns] # only these listed extensions can be used # - {name: CPP, within: CrossPlatform} # CPP can only be used in a given module # # - flags: # - {name: -w, within: []} # -w is allowed nowhere # # - modules: # - {name: [Data.Set, Data.HashSet], as: Set} # if you import Data.Set qualified, it must be as 'Set' # - {name: Control.Arrow, within: []} # Certain modules are banned entirely # # - functions: # - {name: unsafePerformIO, within: []} # unsafePerformIO can only appear in no modules # Add custom hints for this project # # Will suggest replacing "wibbleMany [myvar]" with "wibbleOne myvar" # - error: {lhs: "wibbleMany [x]", rhs: wibbleOne x} # Turn on hints that are off by default # # Ban "module X(module X) where", to require a real export list # - warn: {name: Use explicit module export list} # # Replace a $ b $ c with a . b $ c # - group: {name: dollar, enabled: true} # # Generalise map to fmap, ++ to <> # - group: {name: generalise, enabled: true} # Ignore some builtin hints # - ignore: {name: Use let} # - ignore: {name: Use const, within: SpecialModule} # Only within certain modules # Define some custom infix operators # - fixity: infixr 3 ~^#^~ # To generate a suitable file for HLint do: # $ hlint --default > .hlint.yaml # Protolude does not use String and prefer Text so String is undefined and we should use [Char] - ignore: {name: Use String}
