Package spew implements a deep pretty printer for Go data structures to aid in debugging.

A quick overview of the additional features spew provides over the built-in printing facilities for Go data types are as follows:

• Pointers are dereferenced and followed.

• Circular data structures are detected and handled properly.

• Custom Stringer/error interfaces are optionally invoked, including on unexported types.

• Custom types which only implement the Stringer/error interfaces via a pointer receiver are optionally invoked when passing non-pointer variables.

• Byte arrays and slices are dumped like the hexdump -C command which includes offsets, byte values in hex, and ASCII output (only when using Dump style).
