JConf

Simple configuration library with no dependencies.

Features

• Automatic type conversion when possible
• Configuration can be manipulated at runtime with put() method
• Automatic backup of configuration files

Usage

Initialization:

String confFile = "config/conf.jc";  
Jconf jc = new Jconf(confFile);  

The API exposes methods: get(), getVal() and set(). Getter returns the configuration in the form of

HashMap<String, HashMap<String, Object>>  

Where the key is a category name for a group of settings and the inner HashMap stores the keys and values of the entries under the category.
For example if this is the configuration file:

{General}  
Active = true  
Limit = 1.8  
Bandwidth = 100M  
  
{Not so general}  
Balance = 500  
// Note the format of the list(also, this is a valid comment inside a config file)  
Users = [Hamilton, Webber, Raikkonen]  

jc.get() returns the entire configuration HashMap:

[{Not so general={Users=[Ljava.lang.String;@4b67cf4d, Balance=500}, General={Active=true, Bandwidth=100M, Limit=1.8}}]
// The array under "Users" is simply a String array of the listed users

The getVal() method returns the object value of the requested key:

jc.getVal("General", "Limit);
>> 1.8

The set() method allows the programmer to change values of settings during runtime.

jc.set(String category, String element, String value)  

Supported type conversions:

• "true" || "True" -> boolean true
• "false" || "False" -> boolean false
• "1.1" -> Double 1.1
• "1" -> int 1
• [i1, i2, i3] -> Object array[] = {i1, i2, i3}
  Type will be String if the value could not be converted.
