Lean.MetaM Lean.FormatWithInfos

Return a fmt representing pretty-printed e together with a map from tags in fmt to Elab.Info nodes produced by the delaborator at various subexpressions of e.

def Lean.MessageData.ofFormatWithInfosM (fmt : Lean.MetaM Lean.FormatWithInfos) :
Lean.MessageData

Turns a MetaM FormatWithInfos into a MessageData.lazy which will run the monadic value. Uses the pp.tagAppFns option to annotate constants with terminfo, which is necessary for seeing the type on mouse hover.

source
def Lean.MessageData.ofLazyM (f : Lean.MetaM Lean.MessageData) (es : optParam (Array Lean.Expr) #[]) :
Lean.MessageData

Turns a MetaM MessageData into a MessageData.lazy which will run the monadic value. The optional array of expressions is used to set the hasSyntheticSorry fields, and should comprise the expressions that are included in the message data.

Equations
  • One or more equations did not get rendered due to their size.
source
def Lean.MessageData.ofConst (e : Lean.Expr) :
Lean.MessageData

Pretty print a const expression using delabConst and generate terminfo. This function avoids inserting @ if the constant is for a function whose first argument is implicit, which is what the default toMessageData for Expr does. Panics if e is not a constant.

source
def Lean.MessageData.signature (c : Lake.Name) :
Lean.MessageData

Generates MessageData for a declaration c as c.{<levels>} <params> : <type>, with terminfo.
