Free programming software for linux

The lptools suite provides a complete, programming-language independent, literate programming environment. The suite targets XML documentation, but the underlying system has no bias that would disadvantage other documentation languages.
Also included, and probably worth the price of admission on its own, is a programmable build tool (a make replacement) that can handle very complex and dynamic dependency graphs.
Literate programming is a style of programming, invented by Knuth, which targets human readers first, and the compiler second. In literate code, the documentation is the important thing, and the code organization is subject to it.
The literate programming tools then take on the responsibility of assembling compilable code and cross-referenced documentation from the sources.
The lptools suite provides a complete literate programming environment. The tools are programming language independent. Directives to the system are designed to have minimal effect on readability.
Core tools:
lpcc
- assembles code fragments from lp source files into compilable code
- provides macro substitution facilities
- can be used to produce an lp source file from the assembled code
lproots
- given an lp source, lists the names of all code blocks marked as a root
lpblocks
- given an lp source, lists the names of all blocks it defines
lpdeps
- given an lp source, lists all lp files it references
lptags
- given an lp source, generates ctags for lp and (optionally) code symbols
lphelp
- outputs a complete explanation of the lp system

Kye is a two-dimensional, multithreaded programming language. Unlike most similar languages, it is intended to be more useful than simply a curiosity.
It is especially suited to automated code generation, whereby a Kye program could be evolved to suit a particular application.
Enhancements:
- Implemented memory usage checks

Filecentral is a filesystem browser and file manager. It uses the navigational model of the OSX finder, but tries to integrate into the GNOME Desktop. It uses gnome-vfs and is thus also able to manage remote files.

Filecentral is programmed in C, the best programming language to shoot yourself in the foot.

GIPSpin is a graphical interface programming system which allows code to be visualized and which can generate threaded code.

The user constructs code segments using visual boxes. The program flow is represented as links between the boxes. Complex elements such as threader boxes are available to implement threading.

Currently, simple C code can be automatically parsed and visualized. The user can also start with the GUI to construct code segments which are turned into C++ code.

Intended Audience:

Researchers and programmers who are interested in visual programming and threading. As stated in the development status, a lot of work remains to be done, and we would be happy for suggestions and comments.

We have found that the GIPSpin approach is also helpful for beginning programmers by reducing the intimidation factor in jumping right to text programming, and also helping develop better mental skills for grasping program flow. Seeing how the structured boxes generate code makes the task of programming seem less daunting.

Multi-Agent Grid Engine library is an experiment aimed to make a programming tool for creation of autonomic systems.

Pretty Code Web is a syntax highlighter for publishing code, written in any programming language, to the web.
Written in php it uses syntax files separate from the main code to highlight a specified language.
Main features:
- Syntax highlighting for (potentially) any language.
- User defined syntax files.
- User defined colors
- Separate colors for:
- 6 Keyword Groups
- Text Strings
- Operators
- Block and Line Comments
- Bracket Characters

WebPython is a Web-application development toolkit written in the Python programming language.
WebPython project contains an object relational database layer, portable over MySQL and PostgreSQL; a document templating engine complete with simple built-in automation; and a mechanism to store Python objects in an SQL database, among other features.
Enhancements:
- This release has database caching through the use of memcached, which greatly speeds up database reads.
- A new version of the Tutorial Blog (using this new feature) has also been released.
