Functions

func ReplaceEnv

func ReplaceEnv(value string) string

ReplaceEnv replaces all environment variable placeholders with the contents from the environment.

Types

type Credential

type Credential string

Credential overrides JSON parsing to translate "$(ENV_VAR_NAME)" into the value of the environment variable.

func (*Credential) UnmarshalJSON

func (s *Credential) UnmarshalJSON(data []byte) error

type Entry

type Entry map[string]any

Entry is a single sourced entry. It's just a basic map, but makes it much clearer when building lists of this type, as the type syntax can get a bit messy.

func Parse

func Parse(filename string, data []byte) []Entry

Parse attempts to extract entries from content that is either Jsonnet, JSON or YAML.

It also supports multidoc YAML, and will either return the root object itself if that root is a map[string]any, or if the root is an array, will try returning the contents of said array that are map[string]any's.

type Source

type Source struct {
	Local     *SourceLocal     `json:"local,omitempty"`
	Inline    *SourceInline    `json:"inline,omitempty"`
	Exec      *SourceExec      `json:"exec,omitempty"`
	Backstage *SourceBackstage `json:"backstage,omitempty"`
	GitHub    *SourceGitHub    `json:"github,omitempty"`
}

Source is instantiated from configuration and represents a source of catalog files.

func (Source) Backend

func (s Source) Backend() (SourceBackend, error)

func (Source) Load

func (s Source) Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)

func (Source) Validate

func (s Source) Validate() error

type SourceBackend

type SourceBackend interface {
	String() string
	Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)
}

type SourceBackstage

type SourceBackstage struct {
	Endpoint string     `json:"endpoint"` // https://backstage.company.io/api/catalog/entities
	Token    Credential `json:"token"`
}

func (SourceBackstage) Load

func (s SourceBackstage) Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)

func (SourceBackstage) String

func (s SourceBackstage) String() string

func (SourceBackstage) Validate

func (s SourceBackstage) Validate() error

type SourceEntry

type SourceEntry struct {
	Origin   string // the source origin e.g. inline
	Filename string // the filename that it should be evaluated under e.g. app/main.jsonnet
	Content  []byte // the content of the source
}

SourceEntry is an entry that has been discovered in a source, with the contents of the source file and an Origin that explains where the entry came from, specific to the type of source that produced it.

func (SourceEntry) Parse

func (e SourceEntry) Parse() ([]Entry, error)

type SourceExec

type SourceExec struct {
	Command []string `json:"command"`
}

func (SourceExec) Load

func (s SourceExec) Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)

func (SourceExec) String

func (s SourceExec) String() string

func (SourceExec) Validate

func (s SourceExec) Validate() error

type SourceGitHub

type SourceGitHub struct {
	Repos []string   `json:"repos"`
	Files []string   `json:"files"`
	Token Credential `json:"token"`
}

func (SourceGitHub) Load

func (s SourceGitHub) Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)

func (SourceGitHub) String

func (s SourceGitHub) String() string

func (SourceGitHub) Validate

func (s SourceGitHub) Validate() error

type SourceInline

type SourceInline struct {
	Entries []map[string]any `json:"entries"`
}

func (SourceInline) Load

func (s SourceInline) Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)

func (SourceInline) String

func (s SourceInline) String() string

func (SourceInline) Validate

func (s SourceInline) Validate() error

type SourceLocal

type SourceLocal struct {
	Files []string `json:"files"`
}

func (SourceLocal) Load

func (s SourceLocal) Load(ctx context.Context, logger kitlog.Logger) ([]*SourceEntry, error)

func (SourceLocal) String

func (s SourceLocal) String() string

func (SourceLocal) Validate

func (s SourceLocal) Validate() error
