dump is a Go package for generating pretty-printed dumps of Go values.
There are many functions in the Go ecosystem to do this, including one built
in to Go itself in the fmt package, with the %#v format verb.
This package attempts to find a nice compromise between the built-in formatter
and more advanced formatters like go-spew.
Go types often implement the fmt.GoStringer interface to produce a more
concise representation of values in Go syntax, but conventionally this result
is a single-line string and thus hard to read for larger data structures.
go-spew instead produces a formatted dump of a value by using the reflect
package to analyze its contents, but this often exposes the internals of
data structures that make the result hard to read.
dump.Value works by first obtaining the GoString result for the given
value and then pretty-printing the result so that nested struct, map and
slice literals are easier to read. This allows the result of an overridden
GoString implementation to be included while still producing a readable
result.
