// Package server The commands from the SDK are defined with `cobra` and configured with the
|
|
// `viper` package.
|
|
//
|
|
// This takes place in the `InterceptConfigsPreRunHandler` function.
|
|
// Since the `viper` package is used for configuration the precedence is dictated
|
|
// by that package. That is
|
|
//
|
|
// 1. Command line switches
|
|
// 2. Environment variables
|
|
// 3. Files from configuration values
|
|
// 4. Default values
|
|
//
|
|
// The global configuration instance exposed by the `viper` package is not
|
|
// used by Cosmos SDK in this function. A new instance of `viper.Viper` is created
|
|
// and the following is performed. The environmental variable prefix is set
|
|
// to the current program name. Environmental variables consider the underscore
|
|
// to be equivalent to the `.` or `-` character. This means that an configuration
|
|
// value called `rpc.laddr` would be read from an environmental variable called
|
|
// `MYTOOL_RPC_LADDR` if the current program name is `mytool`.
|
|
//
|
|
// Running the `InterceptConfigsPreRunHandler` also reads `app.toml`
|
|
// and `config.toml` from the home directory under the `config` directory.
|
|
// If `config.toml` or `app.toml` do not exist then those files are created
|
|
// and populated with default values. `InterceptConfigsPreRunHandler` takes
|
|
// two parameters to set/update a custom template to create custom `app.toml`.
|
|
// If these parameters are empty, the server then creates a default template
|
|
// provided by the SDK.
