Summary

Types

state/0

Functions

detect_language()
Detects the language Nova is running in. It checks for the presence of the Elixir and LFE modules, and returns the language.
format_stacktrace(Stacktrace)
Formats a stacktrace into a list of maps. Each map contains the module, function, arity, file, and line number of the function call.
get_apps()
Returns a proplist with all nova applications and their prefix. This function is useful when calulating dynamic routes.
get_env(Parameter, Default)
Works as the regular application:get_env/3 but instead of giving a specific application we target the application that started nova.
get_environment()
Returns which environment nova is started in. This fetches the environment-variable in sys.config for Nova and returns the value found. Defaults to: dev
get_main_app()
Returns the name of the main bw-application (The one that started everything)
set_env(Key, Value)
Sets an environment variable for the main application.
use_stacktrace(Enable)
Enables or disables stacktraces. This is a global setting and affects all requests. If stacktraces are enabled, nova will try to print a stacktrace when an exception is thrown.
