Description

From the listing uploaded by “appupdater”.

Alpus is a viewer application for dictionaries in StarDict, DSL, XDXF, Dictd, and TSV/Plain formats ¹. Features: • Fast and fully offline operation • Searches ignoring case, diacritics, and punctuation • Wildcard search • Fuzzy search • Full-text search • In-page popup translator • History and bookmarks • Customization options Compatibility: Alpus is compatible with the following dictionary/file types: • StarDict dictionaries (*.idx) • DSL dictionaries (*.dsl) • XDXF dictionaries (*.xdxf) • Dictd dictionaries (*.index) • TSV/Plain dictionaries (*.txt, *.dic) • Hunspell dictionaries (*.aff) Setting up dictionaries: • Connect your mobile device to your computer. • Copy dictionary files to the app's documents/files folder on device ². See Android help ³ for details. • Select the dictionary index file as listed in the compatibility section above (or an archive of it) using the "Import Dictionary" option of the "Manage" menu. • Select multiple indexes/files, with each selection assumed and analyzed as one dictionary. (optional) • Select resource ZIP files (if any) to copy during importing. (optional) • Edit properties of the dictionary such as visible name using the "Edit Properties" option of the dictionary menu. (optional) • Create a full-text search index of the dictionary using the "Upgrade" option of the dictionary menu. (optional) • Create profiles to group and organize dictionaries. (optional) Resource files: Resource files of a dictionary can be put into multiple ZIP files with arbitrary sizes and file names. The resource ZIP files placed into the root folder of a dictionary (beside Main.props file) will be detected and indexed automatically. Full-text search: The app supports searching full-text of all dictionaries for exact matches. The feature requires a one-time upgrading ("Upgrade All" option of the "Manage" menu) of a dictionary which can take a very long time to complete, since every single word anywhere on the dictionary is made searchable during the process. Synchronizing between devices: Copying/moving dictionaries between devices is done using one of the two available methods: • "Export Dictionary" to an *.aaf file on the first device and then "Import Dictionary" that *.aaf file on the second • Copy/move whole "Alpus.Config" folder or individual dictionary folders using a file manager or built-in file operations Search types: There are five kinds of searches you can perform on dictionaries. • Regular search: Shows results exactly matching the query. • Extended matching search: Shows results matching the query with case, diacritics, and punctuations ignored. Suggestions include in-phrase and phonetic matches. • Full-text search: Shows list of articles containing exact matches of the query. The scope of search is not limited to headwords and includes all text in all articles (definitions, synonyms, examples, etc). • Fuzzy search: Shows list of articles most similar to the query. The search works like a spell checker for words you're not sure how it's written/spelled. • Wildcard search: Shows list of articles that match the criteria set with a wildcard query. Help and Support: • https://alpusapp.com ¹ No dictionaries are bundled with the application. You will need dictionaries in supported formats to use with the application. ² Typical location of the app's documents folder is: Android/data/com.ngcomputing.fora.android/files ³ https://support.google.com/android/answer/9064445
