Note: it is first coded with all class, method, variable, resource names in translitered telugu, and not in english. i refactored class, method names and major part of code to english. still at very few places may encounter translitered telugu or sanskrit tatsamas. they will be refactored gradually.
supports stardict format.
supports .syn file.
supports pseudo random access on .dict.dz compressed files.
in.bhumiputra.nakshatra package contains facade interface activities, content providers, etc.
in.bhumiputra.nakshatra.nighantu.anga package contains classes modelling stardict dictionary components(Idx, Syn, Index, Dict, Dz, Ifo, Dictionary, etc..), and some datastructures(Address, Entry, Tuple, IntTuple, SortedListsMap etc.). classes in this package contains documentation.
in.bhumiputra.nakshatra.nighantu package contains classes which operates on all Dictionary objects. like Search, Suggestions, Document etc. and a container class Dictionaries , which scans and loads dictionaries as Dictionary objects, and provide access to them. and Document class takes Dictionaries object as member, and generates final result page.
NighantuProvider is main class which is a content provider, and provides search suggestions, and result webpage. It delegates Dictionaries , and Document objects for interface with stardict dictionaries. after creating this provider, we can just load result webpage from a WebView, and display suggestions in SearchView etc. On top of this main underlying functionality we build remaining interface.
For suggestions, normal suggestions are just computed normally. But for Fuzzy suggestions we use FuzzyWuzzy library. as of now we just use only one function to compute nearness between two words. but entire library is included(which is very small).
InitActivity is launcher Activity. it manages permissions, and then launches IndexerActivity activity.
IndexerActivity scans dictionaries, and compare with previous scan information stored, and computes details about any updated dictionaries, or newly installed dictionaries, or deleted dictionaries. based on them it takes appropriate action. if no dictionaries avialable, it shows some help message. If any dictionaries are updated from previous scan (checks timestamps), it silently reindex them. If any new dictionaries found, then it gives user interface to select dictionaries to index, and then indexes selected dictionaries, and exits.
then NakshatraActivity will be launched, and loads main interface. from here we can goto remaining Activities, or use functionalities within it.
