structure Lean.FileMap : Type

Content of a file together with precalculated positions of newlines.

• source : String

  The content of the file.

• positions : Array String.Pos.Raw

  The positions of newline characters. The first entry is always 0 and the last always the index of the last character. In particular, if the last character is a newline, that index will appear twice.

class Lean.MonadFileMap (m : Type → Type) : Type

• getFileMap : m FileMap

def Lean.FileMap.getLastLine (fmap : FileMap) : Nat

The last line should always be positions.size - 1.

def Lean.FileMap.getLine (fmap : FileMap) (x : Nat) : Nat

The line numbers associated with the positions of the FileMap. fmap.getLine i is the iᵗʰ entry of #[1, 2, …, n-1, n-1] where n is the size of positions.

def Lean.FileMap.toPosition (fmap : FileMap) (pos : String.Pos.Raw) : Position

def Lean.FileMap.ofPosition (text : FileMap) (pos : Position) : String.Pos.Raw

Convert a Lean.Position to a String.Pos.

def Lean.FileMap.lineStart (map : FileMap) (line : Nat) : String.Pos.Raw

Returns the position of the start of (1-based) line line. This gives the same result as map.ofPosition ⟨line, 0⟩, but is more efficient.
