Alpus

Alpus is a viewer application for dictionaries in StarDict, DSL, XDXF, Dictd, and TSV/Plain formats ¹.

Features:

• Fast and fully offline operation

• 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 iOS help ² 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
