Options

type Options = Options_ [Rewrite Universe] AnnotatedImports Source #

Command-line options.

data Options_ rewrites imports Source #

Fields

additionalImports :: imports
Imports specified by the command-line flag '--import'.
colorise :: ColoriseFun
Function used to colorize results of certain execution modes.
executionMode :: ExecutionMode
Controls behavior of apply. See ExecutionMode.
extraIgnores :: [FilePath]
Specific files that should be ignored. Paths should be relative to targetDir.
fixityEnv :: FixityEnv
Fixity information for operators used during parsing (of rewrites and target modules). Defaults to base fixities.
iterateN :: Int
Iterate the given rewrites or Retrie computation up to this many times. Iteration may stop before the limit if no changes are made during a given iteration.
randomOrder :: Bool
Whether to randomize the order of target modules before rewriting them.
rewrites :: rewrites
Rewrites specified by command-line flags such as '--adhoc'.
roundtrips :: [RoundTrip]
Paths that should be roundtripped through ghc-exactprint to debug. Specified by the '--roundtrip' command-line flag.
singleThreaded :: Bool
Whether to concurrently rewrite target modules. Mostly useful for viewing debugging output without interleaving it.
targetDir :: FilePath
Directory that contains the code being targeted for rewriting.
targetFiles :: [FilePath]
Instead of targeting all Haskell files in targetDir, only target specific files. Paths should be relative to targetDir.
verbosity :: Verbosity
How much should be output on stdout.

data ExecutionMode Source #

Controls the ultimate action taken by apply. The default action is ExecRewrite.

Constructors

ExecDryRun	Pretend to do rewrites, show diff.
ExecRewrite	Perform rewrites.
ExecExtract	Print the resulting expression for each match.
ExecSearch	Print the matched expressions.

Instances

Show ExecutionMode Source #
Instance details Defined in Retrie.Options Methods showsPrec :: Int -> ExecutionMode -> ShowS # show :: ExecutionMode -> String # showList :: [ExecutionMode] -> ShowS #

defaultOptions :: (Default rewrites, Default imports) => FilePath -> Options_ rewrites imports Source #

Construct default options for the given target directory.

parseOptions :: FixityEnv -> IO Options Source #

Parse options using the given FixityEnv.

Internal

buildGrepChain :: FilePath -> HashSet String -> [FilePath] -> Either [FilePath] (String, [String]) Source #

Either returns an exact list of target paths, or a command for finding them.

forFn :: Options_ x y -> [a] -> (a -> IO b) -> IO [b] Source #

forM, but concurrency and input order controled by Options.

getOptionsParser :: FixityEnv -> IO (Parser ProtoOptions) Source #

Get the options parser. The returned ProtoOptions should be passed to resolveOptions to get final Options.

getTargetFiles :: Options_ a b -> [GroundTerms] -> IO [FilePath] Source #

Find all files to target for rewriting.

parseRewritesInternal :: Options_ a b -> [RewriteSpec] -> IO [Rewrite Universe] Source #

Create Rewrites from string specifications of rewrites. We expose this from Retrie with a nicer type signature as parseRewrites. We have it here so we can use it with ProtoOptions.

parseVerbosity :: Verbosity -> Parser Verbosity Source #

Parser for Verbosity.

type ProtoOptions = Options_ [RewriteSpec] [String] Source #

Options that have been parsed, but not fully resolved.

resolveOptions :: ProtoOptions -> IO Options Source #

Resolve ProtoOptions into Options. Parses rewrites into Rewrites, parses imports, validates options, and extends fixityEnv with any declared fixities in the target directory.
