...The downside is that if you do need time in another format, you'll need to create your own type. By default, slice types will split the environment value on ,; you can change this behavior by setting the envSeparator tag. If you set the envExpand tag, environment variables (either in ${var} or $var format) in the string will be replaced according with the actual value of the variable.

go-containerregistry is a Go library (with companion tools) for interacting with container images and registries using OCI/Docker formats. It provides primitives to read, write, mutate, sign, and copy images and indexes across registries without shelling out to Docker. High-level utilities like crane and gcrane offer convenient CLIs for everyday tasks—listing tags, copying images between registries, flattening, creating tarballs, and more. The library handles authentication via a pluggable...

...CLI releases are tagged with cli/vMAJOR.MINOR.PATCH and published on the Github releases page. As for the library, new versions are tagged with both lib/vMAJOR.MINOR.PATCH and vMAJOR.MINOR.PATCH. The latter tag is required for compatibility with go mod. The JSON format makes integration with programs that produce targets dynamically easier. Each target is one JSON object in its own line. The method and url fields are required. If present, the body field must be base64 encoded. The generated JSON Schema defines the format in detail.

...It is particularly useful for APIs or HTTP clients that represent query parameters as structs—such as in the go-github client library. Each struct field can be annotated with a url:"name" tag to specify the query key. The encoder supports standard Go data types (strings, numbers, booleans, slices, etc.) and handles formatting and escaping automatically.

...Typical use is using environment variables for configuration settings. Envconfig supports the use of struct tags to specify alternate, default, and required environment variables. Envconfig won't process a field with the "ignored" tag set to "true", even if a corresponding environment variable is set. Any field whose type (or pointer-to-type) implements envconfig.Decoder can control its own deserialization. Also, envconfig will use a Set(string) error method like from the flag.Value interface if implemented.
