AppOpts Pile
version 0.0.1

|
The pile provides the application with easy loading of options from config files, management and saving the values back to config files.
The implementation looks into three locations for configuration files:
If a value is present in more than one file the most specific one (highest number) takes precedence.
The user may also choose to load the configuration from a specific file or files using loadFile().
Some rudimentary support for option definitions exists in the pile in the form of OneOpt and OneOptList. Through it one may provide a name, a group, a description and a default value for each option. Options may also be required to be present in at least one config file.
readMultipleFromCfgs() can be used to validate such a list of options.
A project using this pile would include an instance of AppOpts in top level singleton:
class Manager {
AppOpts opts_; /**< the options */
static Manager * unique_;
};
It would then load the settings from all files that are present with opts_.loadFromAll ();.
The code may go on parsing the command line and overriding the values based on user request.
