Add dependency

implementation 'com.tomclaw.minion:minion:1.1.0'

Create async Minion for file

FileStorage storage = FileStorage.create(file);
Minion minion = Minion.lets()
        .async(new ResultCallback() {

            void onReady(Minion minion) {
            	// Data successfully loaded.

            void onFailure(Exception ex) {
            	// Something went wrong.


Save data to specified storage.;

Also, if you created Minion async, you may listen for operation result with callback. ResultCallback() {

    void onReady(Minion minion) {
    	// Data successfully saved.

    void onFailure(Exception ex) {
    	// Something went wrong.

Parse INI from string

Parses INI from specified string synchronously.

Readable storage = StringStorage.create("[group]\nkey=value\nkey2=value2");
Minion minion = Minion.lets()

Set values for specified group and key

If no such group or key exist, they will be created.

minion.setValue("user", "name", "Michael");

It's also extremely easy to set an array of values.

minion.setValue("music", "genres", "Classical", "Lounge", "Dance", "Pop");

Get values for specified group and key

If no such group exist, it will be created.

String name = minion.getValue("user", "name");

Or you can obtain array of values.

String[] genres = minion.getValues("music", "genres");

Get all groups

Returns all group names.

Set<String> names = minion.getGroupNames();

Returns all groups with records.

List<IniGroup> groups = minion.getGroups();

Remove record

Of course, you may just simply remove key and value. Function removeRecord will return removed record. If it doesn't exist, method will return null.

IniRecord record = minion.removeRecord("user", "name");

Remove group

Minion allows to remove whole group of records too. Function removeGroup will return removed group with removed records. If it doesn't exist, method will return null.

IniGroup group = minion.removeGroup("music");

Clear all

If you need to remove all groups (and, also, all records), you can call method clear:


How it works

Minion based on stupidly simple plain-text INI format, it parses, compiles and deliver access blazingly fast. Library is extra-lightweight (~25Kb) and contain no any dependencies. You can use Minion to store some prefs or form-specific data. Simply than ever.
