ElmSyntaxPrint

Pretty printing an elm-syntax tree in a way consistent with elm-format.

toString : Print -> String

All other helpers in this module produce a Print which you can in the end convert to a String with toString

type alias Print =

{ indent : Int } -> String

Pretty printable intermediate representation. See toString

module_ : File -> Print

Print an Elm.Syntax.File.File

That's all you'll need most of the time.

Sometimes it's useful to print only some part of the syntax, to, say, display only an expression in an article or reformat only the touched declarations on save.

moduleHeader :

{ atDocsLines : List (List String)

, comments : List (Node String)

}

-> Module

-> Print

Print an Elm.Syntax.Module.Module (confusingly, that's their name for only the module X exposing (Y) lines)

moduleExposing :

{ atDocsLines : List (List String)

, comments : List (Node String)

}

-> Node Exposing

-> Print

Print the stuff after exposing in a module header. For import exposing: importExposing

expose : TopLevelExpose -> Print

Print a single Elm.Syntax.Exposing.TopLevelExpose

imports : List (Node String) -> List (Node Import) -> Print

Print a set of Elm.Syntax.Import.Imports

import_ : List (Node String) -> Node Import -> Print

Print a single Elm.Syntax.Import.Import

importExposing : List (Node String) -> Node Exposing -> Print

Print the stuff after exposing in an import. For module header exposing: moduleExposing

moduleLevelComments : List String -> Print

Print -- or {- -} comments placed outside of declarations at the top level. For comments within a declaration: comments

comments : List String -> Print

Print -- or {- -} comments placed within a declaration. For top-level comments: moduleLevelComments

comment : String -> Print

Print a single -- or {- -} comment.

, previousEnd : Location

}

-> List (Node Declaration)

-> Print

declaration :

{ portDocumentationComment : Maybe (Node String)

, comments : List (Node String)

}

-> Declaration

Print an Elm.Syntax.Infix.Infix declaration

declarationPort :

{ documentationComment : Maybe (Node String)

, comments : List (Node String)

}

-> Signature

-> Print

Print a port Elm.Syntax.Declaration.Declaration

declarationTypeAlias : List (Node String) -> TypeAlias -> Print

Print an Elm.Syntax.TypeAlias.TypeAlias declaration

expressionNotParenthesized : List (Node String) -> Node Expression -> Print

Print an Elm.Syntax.Expression.Expression

case_ : List (Node String) -> Case -> Print

Print a single Elm.Syntax.Expression.Case

patternNotParenthesized : List (Node String) -> Node Pattern -> Print

Print an Elm.Syntax.Pattern.Pattern

typeNotParenthesized : List (Node String) -> Node TypeAnnotation -> Print

Print an Elm.Syntax.TypeAnnotation.TypeAnnotation

moduleName : ModuleName -> Print

Print an Elm.Syntax.ModuleName.ModuleName

qualifiedReference :

{ qualification : List String

, unqualified : String

}

-> Print

Print a name with its qualification ([] for no qualification)
