Overview ¶
Package regsrc provides helpers for working with source strings that identify resources within a Terraform registry.

Variables ¶
var ( ErrInvalidModuleSource = errors.New("not a valid registry module source") // NameRe is a regular expression defining the format allowed for namespace // or name fields in module registry implementations. NameRe = regexp.MustCompile("^" + nameSubRe + "$") // ProviderRe is a regular expression defining the format allowed for // provider fields in module registry implementations. ProviderRe = regexp.MustCompile("^" + providerSubRe + "$") )
var ( // InvalidHostString is a placeholder returned when a raw host can't be // converted by IDNA spec. It will never be returned for any host for which // Valid() is true. InvalidHostString = "<invalid host>" )
var ( // PublicRegistryHost is a FriendlyHost that represents the public registry. PublicRegistryHost = NewFriendlyHost("registry.terraform.io") )
Functions ¶

Types ¶
type FriendlyHost ¶
type FriendlyHost struct {
Raw string
}
FriendlyHost describes a registry instance identified in source strings by a simple bare hostname like registry.terraform.io.
func NewFriendlyHost ¶
func NewFriendlyHost(host string) *FriendlyHost
func ParseFriendlyHost ¶
func ParseFriendlyHost(source string) (host *FriendlyHost, rest string)
ParseFriendlyHost attempts to parse a valid "friendly host" prefix from the given string. If no valid prefix is found, host will be nil and rest will contain the full source string. The host prefix must terminate at the end of the input or at the first / character. If one or more characters exist after the first /, they will be returned as rest (without the / delimiter). Hostnames containing punycode WILL be parsed successfully since they may have come from an internal normalized source string, however should be considered invalid if the string came from a user directly. This must be checked explicitly for user-input strings by calling Valid() on the returned host.
func (*FriendlyHost) Display ¶
func (h *FriendlyHost) Display() string
Display returns the host formatted for display to the user in CLI or web output.
func (*FriendlyHost) Equal ¶
func (h *FriendlyHost) Equal(other *FriendlyHost) bool
Equal compares the FriendlyHost against another instance taking normalization into account. Invalid hosts cannot be compared and will always return false.
func (*FriendlyHost) Normalized ¶
func (h *FriendlyHost) Normalized() string
Normalized returns the host formatted for internal reference or comparison.
func (*FriendlyHost) String ¶
func (h *FriendlyHost) String() string
String returns the host formatted as the user originally typed it assuming it was parsed from user input.
func (*FriendlyHost) Valid ¶
func (h *FriendlyHost) Valid() bool
Valid returns whether the host prefix is considered valid in any case. Example of invalid prefixes might include ones that don't conform to the host name specifications. Not that IDN prefixes containing punycode are not valid input which we expect to always be in user-input or normalised display form.
type Module ¶
type Module struct {
// RawHost is the friendly host prefix if one was present. It might be nil
// if the original source had no host prefix which implies
// PublicRegistryHost but is distinct from having an actual pointer to
// PublicRegistryHost since it encodes the fact the original string didn't
// include a host prefix at all which is significant for recovering actual
// input not just normalized form. Most callers should access it with Host()
// which will return public registry host instance if it's nil.
RawHost *FriendlyHost
RawNamespace string
RawName string
RawProvider string
RawSubmodule string
}
Module describes a Terraform Registry Module source.
func NewModule ¶
NewModule construct a new module source from separate parts. Pass empty string if host or submodule are not needed.
func ParseModuleSource ¶
ParseModuleSource attempts to parse source as a Terraform registry module source. If the string is not found to be in a valid format, ErrInvalidModuleSource is returned. Note that this can only be used on "input" strings, e.g. either ones supplied by the user or potentially normalised but in Display form (unicode). It will fail to parse a source with a punycoded domain since this is not permitted input from a user. If you have an already normalized string internally, you can compare it without parsing by comparing with the normalized version of the subject with the normal string equality operator.
func (*Module) Display ¶
Display returns the source formatted for display to the user in CLI or web output.
func (*Module) Equal ¶
Equal compares the module source against another instance taking normalization into account.
func (*Module) Host ¶
func (m *Module) Host() *FriendlyHost
Host returns the FriendlyHost object describing which registry this module is in. If the original source string had not host component this will return the PublicRegistryHost.
func (*Module) Module ¶
Module returns just the registry ID of the module, without a hostname or suffix.
func (*Module) Normalized ¶
Normalized returns the source formatted for internal reference or comparison.
func (*Module) String ¶
String returns the source formatted as the user originally typed it assuming it was parsed from user input.
