The libmba package is a collection of mostly independent C modules potentially useful to any project. There are the usual ADTs including a linkedlist, hashmap, pool, stack, and varray, a flexible memory allocator, CSV parser, path canonicalization routine, I18N text abstraction, configuration file module, portable semaphores, condition variables, and more. The code is designed so that individual modules can be integrated into existing codebases rather than requiring the user to commit to the entire library. The code has no typedefs, few comments, and extensive man pages and HTML documentation.
OmegaT is a translation memory application intended for professional translators. It does not translate for you (software that does this is called "machine translation"). It features fuzzy matching, match propagation, simultaneous processing of multiple-file projects, simultaneous use of multiple translation memories, and external glossaries. Document file formats include plain text, HTML, and OpenOffice.org/StarOffice. It has Unicode (UTF-8) support (can be used with non-Latin alphabets). It is compatible with other translation memory applications (TMX Level 1).
libuninum is a library for converting Unicode strings to integers and integers to Unicode strings. Internal computation is done using arbitrary precision arithmetic, so there is no limit on the size of the integer that can be converted. Values are passed and returned as ASCII decimal strings, GNU MP mpz_t objects, or unsigned long integers. Auto-detection of the number system is provided. Very many number systems are supported. Group delimitation for output strings is fully controllable. Command line and graphical interfaces are also provided.
UnicodeDataBrowser is a browser for the UnicodeData.txt file, which contains much useful information but is not easily read by humans. It creates a scrollable table in which columns represent properties. The table may be sorted on any column. Abbreviations are expanded and characters cross-referenced in decomposition and casing fields are named. Regular expression search restricted to a selected column is available. The set of characters for which information is displayed may be restricted to those characters matching a regular expression on a specified property.
