A very simple plugin that will respond to query/commands with the same text that was used to initiate the interaction.
Primary used for testing purposes.
Can be easily installed through the Web UI by using Web UI Plugins.
Alternatively, add echo to your eva.conf file in the enabled_plugins option list and restart Eva.
Echo has a very low priority on the interaction trigger (-100), and so it will only be triggered when no other plugins have opted to respond to a query/command from the client.
When no output has been designated as a response and Echo gets a chance to handle the interaction, it will copy whatever is in the context's input_text variable and set that as output.
Default configuration options can be changed by adding a echo.conf file in your plugin configuration path (can be configured in eva.conf, but usually ~/eva/configs).
To get an idea of what configuration options are available, you can take a look at the echo.conf.spec file in this repository, or use the Web UI Plugins plugin and view them at /plugins/configuration/echo.
Here is a breakdown of the available options:
echo_prefix
Type: String
Default: ''
Here you can set text that will appear before every response from the echo plugin.
