Free lightweight concrete software for linux

Lightweight C++ is a programming language that looks like C++ (a lightweight C++ dialect) and is directly translated to readable C by the lwc preprocessor.
Its more "K&R" and, well, more lightweight. Important thing about lightweight C++ is that by studying the generated C code it is easy to understand how OOP features are implemented and what is the cost of everything.
Adding new features and extensions is also very easy (much easier than adding new C++ extensions to gcc at least), and this is one of lwc goals: To keep evolving.
Main features:
- function overloading,
- member functions,
- inheritance,
- virtual functions (polymorphism),
- multiple inheritance,
- virtual inheritance and pure virtual functions,
- constructors, destructors,
- new and delete,
- default function arguments,
- simple exceptions (no auto destruction of locals)
- and a mechanism of simplistic templates (implemented as high-level multi-line macros).
- operator overloading (works with ptrs when it can)
- +other
Enhancements:
- Changed the generated code for the gcc cleanup attribute so that if a constructor throws, the destructor is not invoked. As in the simple case where we dont have the cleanup attribute and like C++.

LightWeight Time Tracker (LWTT) is a very simple time-tracking program. LightWeight Time Tracker provides independent real-time tracking of multiple tasks (such as programming, lectures, presentations, etc.).

The data are saved to an XML file under the home directory.

Analysis of Reinforced Concrete Elements will assist its user to find out capacity of various Reinforced Concrete Structural Elements.

The following professionals are the target audience:

Structural Engineers
Civil Engineers
Architect
Builders

Installation:

The software is web-based, so you need web-server (Apache) running with PHP. The installaton is very simple. If your document root is /var/www/html , then on uncompressing downloaded compressed file in this "document root", the URL for ARCE application become: http://YourWebSite/arce/

Enhancements:

• Add f to fullscreen & q to exit program
• Add use key to scroll image
• Fix issue slideshow can't zoom fit
• Fix issue rotate
• Add feature zoom in & out (code not yet)

Requirements:

• gtk+

SVN-RaWeb-Light is a Perl module, that once installed and driven by a CGI script provides a lightweight Web-based browser for remote Subversion repositories, not unlike the default HTML one for http:// repositories. (with some improvements).

If you deploy this module in a public URL with a good bandwidth, let me know so I can link to it here for demonstration purposes.

tkCybernetics project is a lightweight cybernetics simulator.
It was designed for didactic purposes, but might be useful for quick tests of circuits.
Main features:
- The usual elements (all apropiately parameteryzable) are available - highpass filter, lowpass filter, integrator, sums, characteristics, completely customizable functions, factors, input-functions and output at arbitrary points of the circuit.
- The results are displayed as graphs and can be exported as postscript. Does currently not support saving of circuits. Checks if circuits are logicaly correct. Its NOT intended for simulation of artificial neural networks or really complex siystems. Its extensible, but only if you know Tcl (and know it well) - port to Python considered.

Enter aims at beign lightweight, yet highly configurable login manager for X. Supporting many different desktop setups. It is written in C with minimal dependencies, making it an excellent choice when using other lightweight window managers, such as fluxbox.

KWrite is a simple text editor, with syntax highlighting, codefolding, dynamic word wrap and more, its the lightweight version of Kate, providing more speed for minor tasks.

KWrite ships per default with KDEBASE package.
