Doxygen is a cross-platform, JavaDoc-like documentation system for C++, C, Objective-C, C#, Java, IDL, Python, PHP, VHDL, and Fortran. Doxygen can be used to generate an on-line class browser (in HTML) and/or an off-line reference manual (in LaTeX or RTF) from a set of source files. Doxygen can also be configured to extract the code-structure from undocumented source files. This includes dependency graphs, class diagrams and hyperlinked source code. This type of information can be very useful to quickly find your way in large source distributions.
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. It is intended for people people who write and want their writing to look great without tinkering with formatting details, font attributes, or page boundaries. On screen, it looks like any word processor, but it uses the TeX engine for printed output and producing richly cross-referenced PDFs. It is stable and fully featured.
Visual Paradigm for UML is a Unified Modeling Language (UML) design tool that supports all UML diagrams, SysML diagrams, and entity relationship diagrams. Visual Paradigm for UML provides extensive use case modeling features, including full function UML use case diagram, flow of events editor, use case/actor grid, and activity diagram generation. Visual Paradigm for UML produces system documentation in PDF, HTML, and MS Word formats. A developer can design system documentation with the template designer. A system analyst can estimate the consequences of changes with impact analysis diagrams, such as matrix and analysis diagram. Visual Paradigm for UML generates Java code.
SDE for Eclipse is a UML modeling environment tightly integrated with Eclipse IDE. It lets you draw all types of UML diagrams (use case diagrams, class diagrams, component diagrams, etc.) in Eclipse, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features the latest UML notation support, a Rational Rose importer, an XMI importer, Microsoft Visio integration, HTML/PDF documentation generators, and plug-in and template support.
GNU Source-highlight produces a document with syntax highlighting when given a source file. It handles many languages, e.g., Java, C/C++, Prolog, Perl, PHP3, Python, Flex, HTML, and other formats, e.g., ChangeLog and log files, as source languages and HTML, XHTML, DocBook, ANSI color escapes, LaTeX, and Texinfo as output formats. Input and output formats can be specified with a regular expression-oriented syntax.
Libecc is a C++ elliptic curve cryptography library that supports fixed-size keys for maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves, and to provide an important source of information for anyone with general interest in ECC.
BOUML is a UML 2 tool box that allows you to specify and generate code in C++, Java, IDL, and PHP. BOUML is very fast and doesn't require much memory to manage several thousands of classes. BOUML is extensible, and the external tools (named plug-outs) can be written in C++ or Java, using BOUML for their definition as any other program. UML models can be exported to HTML pages, including PNG or SVG graphics.
