Alpus is compatible with the following dictionary/file types:
Setting up dictionaries
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.
The app supports searching full-text of all dictionaries for exact matches. The feature requires one-time upgrading ("Upgrade All" option of the "Manage" menu) of a dictionary which can take 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:
There are five kinds of searches you can perform on dictionaries.
Updating the app consists of keeping the portable "Alpus.Config" folder and replacing the remaining files and folders.
Uninstalling the app consists of removing the Alpus bundle. Some files/folders may need to be removed manually which is described here.
Troubleshooting and FAQ
Q: I bought an offline dictionary, can I use it in Alpus?
A: Probably, no. Most standalone dictionaries have it's own proprietary data format incompatible with general-purpose dictionaries. You need dictionary data in one of the supported formats.
Q: Suggestions are slow when a lot of dictionaries are installed.
A: Unlike traditional search auto-completion, Alpus performs a complete search and matching of the query (e.g. occurrences in multi-word phrases) on all dictionaries in profile when suggestions are activated. Grouping dictionaries into smaller sets based on usage context using profiles may be helpful.
Q: I can't find the dictionary I need or the dictionary isn't displayed properly when searching.
A: Importing the dictionary using the latest version of the app or using alternate formats may be helpful.
Q: When I modify/replace Alpus.Config folder manually, my profiles are lost.
A: This is the expected behavior since profiles are stored as app settings (rather than disk files) on mobile devices for the sake of stability.
