incant is a dict(ionary) service client with both command line and GUI versions. incant features multiple-word string searches and attempts to pattern match when a search fails. The GUI version supports browsing, dictionary selection, and intuitive keybindings. incant should work with most versions of tcl/tk, however it has only been tested with TCL/TK 8.0. incant is platform independant (within reason, clearly incant for cmdline doesn't work on MacOS).
Patchutils contains a collection of tools for manipulating patch files: interdiff, combinediff, flipdiff, filterdiff, fixcvsdiff, rediff, lsdiff, grepdiff, splitdiff, recountdiff, and unwrapdiff. You can use interdiff to create an incremental patch between two patches that are against a common source tree, combinediff for creating a cumulative diff from two incremental patches, and flipdiff to transpose two incremental patches. Filterdiff is for extracting or excluding patches from a patch set based on modified files matching shell wildcards. Lsdiff lists modified files in a patch. Rediff, recountdiff, and unwrapdiff correct hand-edited (or otherwise broken) patches.
ICU provides a Unicode implementation, with functions for formatting numbers, dates, times, and currencies (according to locale conventions, transliteration, and parsing text in those formats). It provides flexible patterns for formatting messages, where the pattern determines the order of the variable parts of the messages, and the format for each of those variables. These patterns can be stored in resource files for translation to different languages. Included are more than 100 codepage converters for interaction with non-unicode systems.
Isearch is software for indexing and searching text documents. It supports full text and field based search, relevance ranked results, Boolean queries, and heterogeneous databases. It can parse many kinds of documents "out of the box," including HTML, mail folders, list digests, SGML-style tagged data, and USMARC. It can be extended to support other formats by creating descendant classes in C++ that define the document structure. It is pretty easy to customize in this way, provided that you know some C++ (and you will need to ftp the source code). A CGI interface is also included for Web based searching.
OSSP iselect is an interactive line selection tool for ASCII files, operating via a full-screen Curses-based terminal session. It can be used either as an user interface frontend controlled by a Bourne-Shell/Perl/Tcl backend as its control script or in batch mode as a pipeline filter (usually between grep and the final executing command).
Java HTML generator is a very simple, yet incredibly versatile HTML generator package for Java. It allows you to easily manipulate complex, nested HTML tags. This package is intended to be used with Java Servlets in conjunction with complex dynamic pages (such as large tables). It is based on the new Java 2 container classes.
