MDIFramework provides a ready-to-use architecture to ease the creation MDI-style applications in Java. It takes care of the overall architecture of the main window of the application, with a tabbed architecture, the presence of an HTML printable message area, and so on. It provides a generic API to manage lengthy actions, keeping the interface responsive, and taking care that actions are performed one at a time, without having to bother about it. It can add metadata to already opened files. It manages loading and unloading of external plugins at runtime.
Blacken is a Java library for Roguelike development. It supports arbitrarily resizing the window. It maintains a "preferred size", changing the font size as needed. By default, all applications support Alt-Enter for fullscreen mode. It strives to support Unicode well. A cell contains a sequence of codepoints. Codepoints may be outside the Basic Multilingual Plane or zero-width accents. All key input consists of valid Unicode codepoints. Special keys are handled by codepoints in "private use" planes. Modifier keys are handled through a prefix character (like Unix systems handle Alt via the Escape character).
jWeb1T is an Java tool for efficiently searching n-gram data in the Web 1T 5-gram corpus format. It is based on a binary search algorithm that finds the n-grams and returns their frequency counts in logarithmic time. As the corpus is stored in many files, a simple index is used to retrieve the files containing the n-grams.
