Data types for declaration ranges

The environment extension for declaration ranges is in Lean.DeclarationRange.

structure Lean.DeclarationRange : Type

Store position information for declarations.

• pos : Position
• charUtf16 : Nat

  A precomputed UTF-16 character field as in Lean.Lsp.Position. We need to store this because LSP clients want us to report the range in terms of UTF-16, but converting a Unicode codepoint stored in Lean.Position to UTF-16 requires loading and mapping the target source file, which is IO-heavy.

• endPos : Position
• endCharUtf16 : Nat

  See charUtf16.

Instances For

• Lean.instInhabitedDeclarationRange

instance Lean.instInhabitedDeclarationRange : Inhabited DeclarationRange

Equations

• Lean.instInhabitedDeclarationRange = { default := { pos := default, charUtf16 := default, endPos := default, endCharUtf16 := default } }

instance Lean.instDecidableEqDeclarationRange : DecidableEq DeclarationRange

Equations

• Lean.instDecidableEqDeclarationRange = Lean.decEqDeclarationRange✝

instance Lean.instReprDeclarationRange : Repr DeclarationRange

Equations

• Lean.instReprDeclarationRange = { reprPrec := Lean.reprDeclarationRange✝ }

instance Lean.instToExprDeclarationRange : ToExpr DeclarationRange

Equations

• One or more equations did not get rendered due to their size.

structure Lean.DeclarationRanges : Type

instance Lean.instToExprDeclarationRanges : ToExpr DeclarationRanges

Equations

structure Lean.DeclarationLocation : Type

A declaration location is a declaration range along with the name of the module the declaration resides in.

• module : Name
• range : DeclarationRange

Instances For

• Lean.instInhabitedDeclarationLocation
• Lean.instReprDeclarationLocation

instance Lean.instInhabitedDeclarationLocation : Inhabited DeclarationLocation

Equations

instance Lean.instDecidableEqDeclarationLocation : DecidableEq DeclarationLocation

Equations

• Lean.instDecidableEqDeclarationLocation = Lean.decEqDeclarationLocation✝

instance Lean.instReprDeclarationLocation : Repr DeclarationLocation

Equations

• Lean.instReprDeclarationLocation = { reprPrec := Lean.reprDeclarationLocation✝ }
