Functions

func FormatInput

func FormatInput(json []byte, groups []string) string

FormatInput add 'input' and `groups` objects to the JSON Also temporarily replace `-` as OPA can't handle it

func FormatOutput

func FormatOutput(body []byte) (string, error)

FormatOutput replace the '-' back in where they were

func MatchWildcardChNameRegexp

func MatchWildcardChNameRegexp(query string, exact bool) *regexp.Regexp

MatchWildcardChNameRegexp creates a Regular Expression from a wild-carded path

func MatchWildcardRegexp

func MatchWildcardRegexp(query string, exact bool) *regexp.Regexp

MatchWildcardRegexp creates a Regular Expression from a gNMI wild-carded path This follows the gNMI wildcard syntax https://github.com/openconfig/reference/blob/master/rpc/gnmi/gnmi-path-conventions.md#wildcards-in-paths

func ParseGNMIElements

func ParseGNMIElements(elms []string) (*pb.Path, error)

ParseGNMIElements builds up a gnmi path, from user-supplied text

func SplitPath

func SplitPath(path string) []string

SplitPath splits a gnmi path according to the spec. See https://github.com/openconfig/reference/blob/master/rpc/gnmi/gnmi-path-conventions.md No validation is done. Behavior is undefined if path is an invalid gnmi path. TODO: Do validation?

func SplitPaths

func SplitPaths(paths []string) [][]string

SplitPaths splits multiple gnmi paths

func StrPath

func StrPath(path *pb.Path) string

StrPath builds a human-readable form of a gnmi path. e.g. /a/b/c[e=f]

func StrPathElem

func StrPathElem(pathElem []*pb.PathElem) string

StrPathElem builds a human-readable form of a list of path elements. e.g. /a/b/c[e=f]

func StrVal

func StrVal(val *pb.TypedValue) string

StrVal will return a string representing the supplied value

func TemporaryEvaluate

func TemporaryEvaluate(md metautils.NiceMD) error

TemporaryEvaluate - simple evaluation of rules until OpenPolicyAgent is added This is so that aether-config can be deployed to the cloud in 2021 Q1 with simple RBAC It applies to Set (gnmi) and CompactChanges(admin) and RollbackNetworkChange(admin) TODO replace the following with fine grained RBAC using OpenPolicyAgent Rego in 2021 Q2
