Feature request: override variable #167

Closed pa345 closed 4 years ago

pa345 commented 4 years ago

I would like to have a default config file with a bunch of settings, which is included by other config files. But then I want to override some default settings in the individual files. For example:

@include "default.cfg"

/ this variable is already defined in default.cfg but I want to change it / var_already_defined = another_value;

Unfortunately, in this scenario, libconfig will raise an error about duplicate variables. Would it be possible to allow over-riding variables in this manner?

This feature is available in current master, via CONFIG_OPTION_ALLOW_OVERRIDES/Config::OptionAllowOverrides:

This option controls whether duplicate settings override previous settings with the same name. If this option is turned off, duplicate settings are rejected. By default this option is turned off.
