A collection of useful tools for any Go-based project. As of now, the only tool included is a tool to read configuration files in a folder.

Fully implemented in configLoader.go. Given a folder, reads all text files with a .cfg extension (other extensions can be read by changing the configType variable).

Each setting should be written in its own line, with the format name = value. Empty lines are ignored. Comments can be added by prefixing the line with # or //.

Example of a configuration file:

#Connection settings
localServer = true
serverIP = 192.168.40.112:8432

//Test settings
nInstances = 24
updateRate = 0.8
queryList = 1 2 3 4 5

Multiple methods to facilitate configuration reading are provided. It is possible to read directly the fields with their intended type (e.g., GetInt64Config). Methods for most basic types are included.

Furthermore, it is possible to provide a default value to be returned when the key is not present. E.g., GetInt64Config("myKey", -1) will return the value associated to "myKey" if present, otherwise returns -1 (in int64 form).

GetConfig, GetAndHasConfig and GetOrDefault can be used for values of any type. They return the value in string form. GetAndHasConfig also returns a boolean representing if the key is present or not. Finally, GetOrDefault receives an extra argument corresponding to the default value to return if the key isn't present.
