const classafMongo::PrettyPrinter

sys::Obj
  afMongo::PrettyPrinter

Pretty prints MongoDB documents to a JSON-esque string. Useful for debugging.

Note PrettyPrinter only pretty prints if the resulting text string if greater than maxWidth. So if PrettyPrinter appears not to be working, then try setting a smaller maxWidth.

str := PrettyPrinter { maxWidth=20 }.print(mongoDoc)

convertHook

Source

virtual Obj? convertHook(Obj? val)

A simple override hook to alter values before they are printed.

By default this just returns the given value.

indent

Source

const Str indent := " "

The indent string used to indent the document.

make

Source

new make(|This? f := null)

Creates a PrettyPrinter with the default pretty printing options. May be either a PrettyPrintOptions instance, or just false to disable pretty printing.

printer := PrettyPrinter()
printer := PrettyPrinter { it.indent="\t"; it.maxWidth=40; }

maxWidth
