# jsonnet-config-demo-go
A Go demo using https://jsonnet.org/ for configuration.
Package `config` provides a generic function `MustParse`, that evaluates the given config file using jsonnet and unmarshals the generated JSON into the given configuration struct type with exported fields. [github.com/go-playground/validator](https://github.com/go-playground/validator) struct tags can be used to constraint individual fields.
In the provided [example](https://github.com/romshark/jsonnet-config-demo-go/tree/main/cmd/example1), the following jsonnet configuration:
```jsonnet
local AdminName(name='') = 'user_admin_' + name;
{
host: 'localhost:8080',
admins: [AdminName(name='Bob'), AdminName(name='Alice')],
}
```
Is parsed into:
```go
type Config struct {
Host string `json:"host" validate:"required,hostname_port"`
Admins []string `json:"admins" validate:"required"`
}
```
