unsafe def Lean.PrettyPrinter.registerParserCompilers : IO Unit

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.

Equations

• Lean.MessageData.ofFormatWithInfosM fmt = Lean.MessageData.lazy fun (ctx : Lean.PPContext) => ctx.runMetaM (Lean.MessageData.ofFormatWithInfos <$> fmt)

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.

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.

def Lean.MessageData.ofConstName (constName : Lake.Name) : Lean.MessageData

Pretty print a constant given its name, similar to Lean.MessageData.ofConst. Uses the constant's universe level parameters when pretty printing. If there is no such constant in the environment, the name is simply formatted.

Equations

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

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

Equations

• Lean.MessageData.signature c = Lean.MessageData.ofFormatWithInfosM (Lean.PrettyPrinter.ppSignature c)
