RubyScript2Exe transforms your Ruby script into a standalone Windows or Linux executable. You can look at it as a "compiler", for it collects all necessary files to run your script on an other machine.
Transpiles/Converts Pascal to Working PHP Source Code
PAS2PHP will translate a large subset of Object Pascal to PHP, allowing you to write web applications using Lazarus/FreePascal, and then run the application on a standard HTML/PHP server. Over the last week, a lot of work has gone into PAS2PHP. Most of the major issues are resolved. There are still a number of incompatibilities which are either not fixable, or have simple workarounds. As of v0.5, you should be able to write entire PHP applications in Pascal. The key to coding for PAS2PHP is to understand the limitations of PHP. Read the example code provided, and always check the outputed PHP code to understand how this works. As a guide to what PAS2PHP can achieve... my web site is written in Pascal, and then converted to PHP. (The code is in the source package). PAS2PHP uses the Pascal Parse Tree Classes (PasTree) which comes with FreePascal, and therefore the parsing limits are defined by this library.
DURIAN is a Free Delphi Web Application Server for make interactive dynamic web documents in the Pascal server-side html-embedded scripting language for Windows (Delphi) and Linux (Kylix).
Yet another scripting language Main features: - Pointers - Structures - Objectoriented programming (yet to come) - code in plain english - easy to learn (based on C, C++, Java, Pascal, Python, Lua)
Oberon V4 for Linux and sources for different Oberon V4 implementation
Here you can find both an Oberon V4 system for Linux (x86) as well as a collection of sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server and on the one of the University of Linz where Mössenböck's group did further development after he left ETH and the Group at ETH concentrated on System 3. More Information can be found in the wiki https://sourceforge.net/p/oberon/wiki/Home/ of this Project and on Wikipedia https://en.wikipedia.org/wiki/Oberon_(operating_system). In 2013 they were moved here for easy access and, in case of interest, collaboration on further development. The Oberon mailing list is an established channel for its discussion and followed also by the administrators of this SF project.  ftp://ftp.ethoberon.ethz.ch/Oberon/OberonV4/  ftp://oberon.ssw.uni-linz.ac.at/pub/Oberon/  https://lists.inf.ethz.ch/mailman/listinfo/oberon
RUG is an universal machine-friendly binary file generator. Together with suitable macro packages, it can be used to assemble executables for almost any known processor. The main goal is to build a backend for a future Scheme translator.
'PASC++AL' will be an education application. It will be simulation of compiler and virtual machine for PASCAL language write in C++. This project will be realized under Uniwersity of Podlasie (POLAND).
FORTH-like language compiler for AVR ATMega
Iterpreter of Pascal language which may help programmers doing ther job. Include basic operations in/out, declarations of variables.
AllInOneRuby creates an Windows or Linux executable that includes both the Ruby interpreter and the runtime libraries. Why? Because it's sometimes not easy, or allowed to do a complete Ruby installation. That's where AllInOneRuby comes in.
E Integrated Development Environment Targeting All Systems
NOTE: Project has been delayed due to other tasks. I will return to this project in 2018. This is a new project which will be available soon. I wanted to bring AmigaE back to life, so I wrote an E to C transpiler which creates C code compatible CC65/CMOC/VBCC/BCC/GCC/TCC/LCC etc. The aim is to bring AmigaE to every possible platform in one hit.
