Outputable

Description

This module defines classes and functions for pretty-printing. It also exports a number of helpful debugging and other utilities such as trace and panic.

The interface to this module is very similar to the standard Hughes-PJ pretty printing module, except that it exports a number of additional functions that are rarely used, and works over the SDoc type.

Pretty printing combinators

data SDoc Source #

Represents a pretty-printable document.

To display an SDoc, use printSDoc, printSDocLn, bufLeftRenderSDoc, or renderWithStyle. Avoid calling runSDoc directly as it breaks the abstraction layer.

Defined in Outputable

runSDoc :: SDoc -> SDocContext -> Doc Source #

interppSP :: Outputable a => [a] -> SDoc Source #

Returns the separated concatenation of the pretty printed things.

interpp'SP :: Outputable a => [a] -> SDoc Source #

Returns the comma-separated concatenation of the pretty printed things.

pprQuotedList :: Outputable a => [a] -> SDoc Source #

Returns the comma-separated concatenation of the quoted pretty printed things.

[x,y,z]  ==>  `x', `y', `z'

pprWithCommas Source #

Arguments

:: (a -> SDoc)

The pretty printing function to use

-> [a]

The things to be pretty printed

-> SDoc

SDoc where the things have been pretty printed, comma-separated and finally packed into a paragraph.

pprWithBars Source #

Arguments

:: (a -> SDoc)

The pretty printing function to use

-> [a]

The things to be pretty printed

-> SDoc

SDoc where the things have been pretty printed, bar-separated and finally packed into a paragraph.

nest :: Int -> SDoc -> SDoc Source #

Indent SDoc some specified amount

doublePrec :: Int -> Double -> SDoc Source #

doublePrec p n shows a floating point number n with p digits of precision after the decimal point.

(<>) :: SDoc -> SDoc -> SDoc Source #

Join two SDoc together horizontally without a gap

(<+>) :: SDoc -> SDoc -> SDoc Source #

Join two SDoc together horizontally with a gap between them

hcat :: [SDoc] -> SDoc Source #

Concatenate SDoc horizontally

hsep :: [SDoc] -> SDoc Source #

Concatenate SDoc horizontally with a space between each one

($$) :: SDoc -> SDoc -> SDoc Source #

Join two SDoc together vertically; if there is no vertical overlap it "dovetails" the two onto one line

($+$) :: SDoc -> SDoc -> SDoc Source #

Join two SDoc together vertically

vcat :: [SDoc] -> SDoc Source #

Concatenate SDoc vertically with dovetailing

sep :: [SDoc] -> SDoc Source #

Separate: is either like hsep or like vcat, depending on what fits

cat :: [SDoc] -> SDoc Source #

Catenate: is either like hcat or like vcat, depending on what fits

fsep :: [SDoc] -> SDoc Source #

A paragraph-fill combinator. It's much like sep, only it keeps fitting things on one line until it can't fit any more.

fcat :: [SDoc] -> SDoc Source #

This behaves like fsep, but it uses <> for horizontal conposition rather than <+>

hang Source #

Arguments

:: SDoc

The header

-> Int

Amount to indent the hung body

-> SDoc

The hung body, indented and placed below the header

-> SDoc 

hangNotEmpty :: SDoc -> Int -> SDoc -> SDoc Source #

This behaves like hang, but does not indent the second document when the header is empty.

punctuate Source #

Arguments

:: SDoc

The punctuation

-> [SDoc]

The list that will have punctuation added between every adjacent pair of elements

-> [SDoc]

Punctuated list

speakNth :: Int -> SDoc Source #

Converts an integer to a verbal index:

speakNth 1 = text "first"
speakNth 5 = text "fifth"
speakNth 21 = text "21st"

speakN :: Int -> SDoc Source #

Converts an integer to a verbal multiplicity:

speakN 0 = text "none"
speakN 5 = text "five"
speakN 10 = text "10"

speakNOf :: Int -> SDoc -> SDoc Source #

Converts an integer and object description to a statement about the multiplicity of those objects:

speakNOf 0 (text "melon") = text "no melons"
speakNOf 1 (text "melon") = text "one melon"
speakNOf 3 (text "melon") = text "three melons"

plural :: [a] -> SDoc Source #

Determines the pluralisation suffix appropriate for the length of a list:

plural [] = char 's'
plural ["Hello"] = empty
plural ["Hello", "World"] = char 's'

isOrAre :: [a] -> SDoc Source #

Determines the form of to be appropriate for the length of a list:

isOrAre [] = text "are"
isOrAre ["Hello"] = text "is"
isOrAre ["Hello", "World"] = text "are"

doOrDoes :: [a] -> SDoc Source #

Determines the form of to do appropriate for the length of a list:

doOrDoes [] = text "do"
doOrDoes ["Hello"] = text "does"
doOrDoes ["Hello", "World"] = text "do"

coloured :: PprColour -> SDoc -> SDoc Source #

Apply the given colour/style for the argument.

Only takes effect if colours are enabled.

Converting SDoc into strings and outputing it

printSDoc :: Mode -> DynFlags -> Handle -> PprStyle -> SDoc -> IO () Source #

The analog of printDoc_ for SDoc, which tries to make sure the terminal doesn't get screwed up by the ANSI color codes if an exception is thrown during pretty-printing.

printSDocLn :: Mode -> DynFlags -> Handle -> PprStyle -> SDoc -> IO () Source #

Like printSDoc but appends an extra newline.

printForC :: DynFlags -> Handle -> SDoc -> IO () Source #

Like printSDocLn but specialized with LeftMode and PprCode CStyle. This is typically used to output C-- code.

bufLeftRenderSDoc :: DynFlags -> BufHandle -> PprStyle -> SDoc -> IO () Source #

An efficient variant of printSDoc specialized for LeftMode that outputs to a BufHandle.

pprHsChar :: Char -> SDoc Source #

Special combinator for showing character literals.

pprHsString :: FastString -> SDoc Source #

Special combinator for showing string literals.

pprHsBytes :: ByteString -> SDoc Source #

Special combinator for showing bytestring literals.

pprPrimChar :: Char -> SDoc Source #

Special combinator for showing unboxed literals.

Controlling the style in which output is printed

data BindingSite Source #

BindingSite is used to tell the thing that prints binder what language construct is binding the identifier. This can be used to decide how much info to print. Also see Note [Binding-site specific printing] in PprCore

data PrintUnqualified Source #

When printing code that contains original names, we need to map the original names back to something the user understands. This is the purpose of the triple of functions that gets passed around when rendering SDoc.

type QueryQualifyName = Module -> OccName -> QualifyName Source #

Given a Name's Module and OccName, decide whether and how to qualify it.

type QueryQualifyModule = Module -> Bool Source #

For a given module, we need to know whether to print it with a package name to disambiguate it.

type QueryQualifyPackage = UnitId -> Bool Source #

For a given package, we need to know whether to print it with the component id to disambiguate it.

alwaysQualifyNames :: QueryQualifyName Source #

NB: This won't ever show package IDs

withPprStyleDoc :: DynFlags -> PprStyle -> SDoc -> Doc Source #

This is not a recommended way to render SDoc, since it breaks the abstraction layer of SDoc. Prefer to use printSDoc, printSDocLn, bufLeftRenderSDoc, or renderWithStyle instead.

pprDeeperList :: ([SDoc] -> SDoc) -> [SDoc] -> SDoc Source #

Truncate a list that is longer than the current depth.

mkErrStyle :: DynFlags -> PrintUnqualified -> PprStyle Source #

Style for printing error messages

Error handling and debugging utilities

pprPanic :: HasCallStack => String -> SDoc -> a Source #

Throw an exception saying "bug in GHC"

pprSorry :: String -> SDoc -> a Source #

Throw an exception saying "this isn't finished yet"

assertPprPanic :: HasCallStack => String -> Int -> SDoc -> a Source #

Panic with an assertation failure, recording the given file and line number. Should typically be accessed with the ASSERT family of macros

pprPgmError :: String -> SDoc -> a Source #

Throw an exception saying "bug in pgm being compiled" (used for unusual program errors)

pprTrace :: String -> SDoc -> a -> a Source #

If debug output is on, show some SDoc on the screen

pprTraceDebug :: String -> SDoc -> a -> a Source #

pprTraceIt :: Outputable a => String -> a -> a Source #

pprTraceIt desc x is equivalent to pprTrace desc (ppr x) x

warnPprTrace :: Bool -> String -> Int -> SDoc -> a -> a Source #

Just warn about an assertion failure, recording the given file and line number. Should typically be accessed with the WARN macros

pprSTrace :: HasCallStack => SDoc -> a -> a Source #

If debug output is on, show some SDoc on the screen along with a call stack when available.

pprTraceException :: ExceptionMonad m => String -> SDoc -> m a -> m a Source #

pprTraceException desc x action runs action, printing a message if it throws an exception.

trace :: String -> a -> a Source #

The trace function outputs the trace message given as its first argument, before returning the second argument as its result.

For example, this returns the value of f x but first outputs the message.

>>> let x = 123; f = show
>>> trace ("calling f with x = " ++ show x) (f x)
"calling f with x = 123
123"

The trace function should only be used for debugging, or for monitoring execution. The function is not referentially transparent: its type indicates that it is a pure function but it has the side effect of outputting the trace message.

pgmError :: String -> a Source #

Panics and asserts.

panic :: String -> a Source #

Panics and asserts.

sorry :: String -> a Source #

Panics and asserts.

assertPanic :: String -> Int -> a Source #

Throw a failed assertion exception for a given filename and line number.

pprDebugAndThen :: DynFlags -> (String -> a) -> SDoc -> SDoc -> a Source #
