Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
go-errors 
Yet another errors package, implementing error handling primitives with error wrapping and error tracing.
Installation
The recommended way to install go-errors is:
go get -u gopkg.in/src-d/go-errors.v1
Examples
The Kind type allows you to create new errors containing the stack trace and also check if an error is of a particular kind.
var ErrExample = errors.NewKind("example")
err := ErrExample.New()
if ErrExample.Is(err) {
fmt.Printf("%+v\n", err)
}
// Example Output:
// example

var ErrMaxLimitReached = errors.NewKind("max. limit reached: %d")
err := ErrMaxLimitReached.New(42)
if ErrMaxLimitReached.Is(err) {
fmt.Println(err)
}
// Output: max. limit reached: 42Error wrapping
var ErrNetworking = errors.NewKind("network error")
err := ErrNetworking.Wrap(io.EOF)
if ErrNetworking.Is(err) {
fmt.Println(err)
}
// Output: network error: EOFYou can find these examples and many more in the examples file.
