+[![GoDoc](https://godoc.org/github.com/juju/errors?status.svg)](https://godoc.org/github.com/juju/errors)
+
+The juju/errors provides an easy way to annotate errors without losing the
+orginal error context.
+
+The exported `New` and `Errorf` functions are designed to replace the
+`errors.New` and `fmt.Errorf` functions respectively. The same underlying
+error is there, but the package also records the location at which the error
+was created.
+
+A primary use case for this library is to add extra context any time an
+error is returned from a function.
+
+
+	    if err := SomeFunc(); err != nil {
+		    return err
+		}
+
+This instead becomes:
+
+
+	    if err := SomeFunc(); err != nil {
+		    return errors.Trace(err)
+		}
+
+which just records the file and line number of the Trace call, or
+
+
+	    if err := SomeFunc(); err != nil {
+		    return errors.Annotate(err, "more context")
+		}
+
+which also adds an annotation to the error.
+
+When you want to check to see if an error is of a particular type, a helper
+function is normally exported by the package that returned the error, like the
+`os` package does.  The underlying cause of the error is available using the
+`Cause` function.
+
+
+	os.IsNotExist(errors.Cause(err))
+
+The result of the `Error()` call on an annotated error is the annotations joined
+with colons, then the result of the `Error()` method for the underlying error
+that was the cause.
+
+
+	err := errors.Errorf("original")
+	err = errors.Annotatef(err, "context")
+	err = errors.Annotatef(err, "more context")
+	err.Error() -> "more context: context: original"
+
+Obviously recording the file, line and functions is not very useful if you
+cannot get them back out again.
+
+
+	errors.ErrorStack(err)
+
+will return something like:
+
+
+	first error
+	github.com/juju/errors/annotation_test.go:193:
+	github.com/juju/errors/annotation_test.go:194: annotation
+	github.com/juju/errors/annotation_test.go:195:
+	github.com/juju/errors/annotation_test.go:196: more context
+	github.com/juju/errors/annotation_test.go:197:
+
+The first error was generated by an external system, so there was no location
+associated. The second, fourth, and last lines were generated with Trace calls,
+and the other two through Annotate.
+
+Sometimes when responding to an error you want to return a more specific error
+for the situation.
+
+
+	    if err := FindField(field); err != nil {
+		    return errors.Wrap(err, errors.NotFoundf(field))
+		}
+
+This returns an error where the complete error stack is still available, and
+`errors.Cause()` will return the `NotFound` error.
+
+
+
+
+
+
+## func AlreadyExistsf
+``` go
+func AlreadyExistsf(format string, args ...interface{}) error
+```
+AlreadyExistsf returns an error which satisfies IsAlreadyExists().
+
+
+## func Annotate
+``` go
+func Annotate(other error, message string) error
+```
+Annotate is used to add extra context to an existing error. The location of
+the Annotate call is recorded with the annotations. The file, line and
+function are also recorded.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Annotate(err, "failed to frombulate")
+	}
+
+
+## func Annotatef
+``` go
+func Annotatef(other error, format string, args ...interface{}) error
+```
+Annotatef is used to add extra context to an existing error. The location of
+the Annotate call is recorded with the annotations. The file, line and
+function are also recorded.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Annotatef(err, "failed to frombulate the %s", arg)
+	}
+
+
+## func Cause
+``` go
+func Cause(err error) error
+```
+Cause returns the cause of the given error.  This will be either the
+original error, or the result of a Wrap or Mask call.
+
+Cause is the usual way to diagnose errors that may have been wrapped by
+the other errors functions.
+
+
+## func DeferredAnnotatef
+``` go
+func DeferredAnnotatef(err *error, format string, args ...interface{})
+```
+DeferredAnnotatef annotates the given error (when it is not nil) with the given
+format string and arguments (like fmt.Sprintf). If *err is nil, DeferredAnnotatef
+does nothing. This method is used in a defer statement in order to annotate any
+resulting error with the same message.
+
+For example:
+
+
+	defer DeferredAnnotatef(&err, "failed to frombulate the %s", arg)
+
+
+## func Details
+``` go
+func Details(err error) string
+```
+Details returns information about the stack of errors wrapped by err, in
+the format:
+
+
+	[{filename:99: error one} {otherfile:55: cause of error one}]
+
+This is a terse alternative to ErrorStack as it returns a single line.
+
+
+## func ErrorStack
+``` go
+func ErrorStack(err error) string
+```
+ErrorStack returns a string representation of the annotated error. If the
+error passed as the parameter is not an annotated error, the result is
+simply the result of the Error() method on that error.
+
+If the error is an annotated error, a multi-line string is returned where
+each line represents one entry in the annotation stack. The full filename
+from the call stack is used in the output.
+
+
+	first error
+	github.com/juju/errors/annotation_test.go:193:
+	github.com/juju/errors/annotation_test.go:194: annotation
+	github.com/juju/errors/annotation_test.go:195:
+	github.com/juju/errors/annotation_test.go:196: more context
+	github.com/juju/errors/annotation_test.go:197:
+
+
+## func Errorf
+``` go
+func Errorf(format string, args ...interface{}) error
+```
+Errorf creates a new annotated error and records the location that the
+error is created.  This should be a drop in replacement for fmt.Errorf.
+
+For example:
+
+
+	return errors.Errorf("validation failed: %s", message)
+
+
+## func IsAlreadyExists
+``` go
+func IsAlreadyExists(err error) bool
+```
+IsAlreadyExists reports whether the error was created with
+AlreadyExistsf() or NewAlreadyExists().
+
+
+## func IsNotFound
+``` go
+func IsNotFound(err error) bool
+```
+IsNotFound reports whether err was created with NotFoundf() or
+NewNotFound().
+
+
+## func IsNotImplemented
+``` go
+func IsNotImplemented(err error) bool
+```
+IsNotImplemented reports whether err was created with
+NotImplementedf() or NewNotImplemented().
+
+
+## func IsNotSupported
+``` go
+func IsNotSupported(err error) bool
+```
+IsNotSupported reports whether the error was created with
+NotSupportedf() or NewNotSupported().
+
+
+## func IsNotValid
+``` go
+func IsNotValid(err error) bool
+```
+IsNotValid reports whether the error was created with NotValidf() or
+NewNotValid().
+
+
+## func IsUnauthorized
+``` go
+func IsUnauthorized(err error) bool
+```
+IsUnauthorized reports whether err was created with Unauthorizedf() or
+NewUnauthorized().
+
+
+## func Mask
+``` go
+func Mask(other error) error
+```
+Mask hides the underlying error type, and records the location of the masking.
+
+
+## func Maskf
+``` go
+func Maskf(other error, format string, args ...interface{}) error
+```
+Mask masks the given error with the given format string and arguments (like
+fmt.Sprintf), returning a new error that maintains the error stack, but
+hides the underlying error type.  The error string still contains the full
+annotations. If you want to hide the annotations, call Wrap.
+
+
+## func New
+``` go
+func New(message string) error
+```
+New is a drop in replacement for the standard libary errors module that records
+the location that the error is created.
+
+For example:
+
+
+	return errors.New("validation failed")
+
+
+## func NewAlreadyExists
+``` go
+func NewAlreadyExists(err error, msg string) error
+```
+NewAlreadyExists returns an error which wraps err and satisfies
+IsAlreadyExists().
+
+
+## func NewNotFound
+``` go
+func NewNotFound(err error, msg string) error
+```
+NewNotFound returns an error which wraps err that satisfies
+IsNotFound().
+
+
+## func NewNotImplemented
+``` go
+func NewNotImplemented(err error, msg string) error
+```
+NewNotImplemented returns an error which wraps err and satisfies
+IsNotImplemented().
+
+
+## func NewNotSupported
+``` go
+func NewNotSupported(err error, msg string) error
+```
+NewNotSupported returns an error which wraps err and satisfies
+IsNotSupported().
+
+
+## func NewNotValid
+``` go
+func NewNotValid(err error, msg string) error
+```
+NewNotValid returns an error which wraps err and satisfies IsNotValid().
+
+
+## func NewUnauthorized
+``` go
+func NewUnauthorized(err error, msg string) error
+```
+NewUnauthorized returns an error which wraps err and satisfies
+IsUnauthorized().
+
+
+## func NotFoundf
+``` go
+func NotFoundf(format string, args ...interface{}) error
+```
+NotFoundf returns an error which satisfies IsNotFound().
+
+
+## func NotImplementedf
+``` go
+func NotImplementedf(format string, args ...interface{}) error
+```
+NotImplementedf returns an error which satisfies IsNotImplemented().
+
+
+## func NotSupportedf
+``` go
+func NotSupportedf(format string, args ...interface{}) error
+```
+NotSupportedf returns an error which satisfies IsNotSupported().
+
+
+## func NotValidf
+``` go
+func NotValidf(format string, args ...interface{}) error
+```
+NotValidf returns an error which satisfies IsNotValid().
+
+
+## func Trace
+``` go
+func Trace(other error) error
+```
+Trace adds the location of the Trace call to the stack.  The Cause of the
+resulting error is the same as the error parameter.  If the other error is
+nil, the result will be nil.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Trace(err)
+	}
+
+
+## func Unauthorizedf
+``` go
+func Unauthorizedf(format string, args ...interface{}) error
+```
+Unauthorizedf returns an error which satisfies IsUnauthorized().
+
+
+## func Wrap
+``` go
+func Wrap(other, newDescriptive error) error
+```
+Wrap changes the Cause of the error. The location of the Wrap call is also
+stored in the error stack.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    newErr := &packageError{"more context", private_value}
+	    return errors.Wrap(err, newErr)
+	}
+
+
+## func Wrapf
+``` go
+func Wrapf(other, newDescriptive error, format string, args ...interface{}) error
+```
+Wrapf changes the Cause of the error, and adds an annotation. The location
+of the Wrap call is also stored in the error stack.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Wrapf(err, simpleErrorType, "invalid value %q", value)
+	}
+
+
+
+## type Err
+``` go
+type Err struct {
+    // contains filtered or unexported fields
+}
+```
+Err holds a description of an error along with information about
+where the error was created.
+
+It may be embedded in custom error types to add extra information that
+this errors package can understand.
+
+
+
+
+
+
+
+
+
+### func NewErr
+``` go
+func NewErr(format string, args ...interface{}) Err
+```
+NewErr is used to return an Err for the purpose of embedding in other
+structures.  The location is not specified, and needs to be set with a call
+to SetLocation.
+
+For example:
+
+
+	type FooError struct {
+	    errors.Err
+	    code int
+	}
+	
+	func NewFooError(code int) error {
+	    err := &FooError{errors.NewErr("foo"), code}
+	    err.SetLocation(1)
+	    return err
+	}
+
+
+
+
+### func (\*Err) Cause
+``` go
+func (e *Err) Cause() error
+```
+The Cause of an error is the most recent error in the error stack that
+meets one of these criteria: the original error that was raised; the new
+error that was passed into the Wrap function; the most recently masked
+error; or nil if the error itself is considered the Cause.  Normally this
+method is not invoked directly, but instead through the Cause stand alone
+function.
+
+
+
+### func (\*Err) Error
+``` go
+func (e *Err) Error() string
+```
+Error implements error.Error.
+
+
+
+### func (\*Err) Location
+``` go
+func (e *Err) Location() (filename string, line int)
+```
+Location is the file and line of where the error was most recently
+created or annotated.
+
+
+
+### func (\*Err) Message
+``` go
+func (e *Err) Message() string
+```
+Message returns the message stored with the most recent location. This is
+the empty string if the most recent call was Trace, or the message stored
+with Annotate or Mask.
+
+
+
+### func (\*Err) SetLocation
+``` go
+func (e *Err) SetLocation(callDepth int)
+```
+SetLocation records the source location of the error at callDepth stack
+frames above the call.
+
+
+
+### func (\*Err) StackTrace
+``` go
+func (e *Err) StackTrace() []string
+```
+StackTrace returns one string for each location recorded in the stack of
+errors. The first value is the originating error, with a line for each
+other annotation or tracing of the error.
+
+
+
+### func (\*Err) Underlying
+``` go
+func (e *Err) Underlying() error
+```
+Underlying returns the previous error in the error stack, if any. A client
+should not ever really call this method.  It is used to build the error
+stack and should not be introspected by client calls.  Or more
+specifically, clients should not depend on anything but the `Cause` of an
+error.
