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.
