Conseptizer is the combination of two ideas: a closure(-mimic) / higher-order programming and dynamic typing library for the C programming language, and a very dynamic programming language that provides expressiveness through simplicity. It offers powerful features that cannot be found in the mainstream today. Each of these two aspects can be useful on their own, but the combination and tight integration in Conseptizer means that if at some point your runtime performance requirements are not fulfilled by the dynamic language, it is very easy to migrate parts of your program code to C.
The Go Programming Language (Go) is an expressive, concise, clean, and efficient language with concurrency mechanisms that make it easy to write programs that get the most out of multicore and networked machines. Its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
HGL is a compiler/interpreter suite for developing images. It features its own simple but powerful language, Lua integration, output in various formats as well as runtime input handled by plugins, and easy integration into various environments like Web servers or graphical applications. The input is taken from a source file, which has to be compiled for quick and frequent access by the interpreter. An interpreter then runs the compiled files, takes input from custom plugins (if neccessary), and outputs its result via custom plugins.
Nimrod is a statically typed, imperative programming language that tries to give the programmer ultimate power without compromising on runtime efficiency. This means it focuses on compile-time mechanisms in all their various forms. Beneath a nice infix/indentation based syntax with a powerful (AST based, hygienic) macro system lies a semantic model that supports a soft realtime GC on thread local heaps. Asynchronous message passing is used between threads, so no "stop the world" mechanism is necessary. An unsafe shared memory heap is also provided for the increased efficiency that results from that model.
Eero is a binary-compatible variant of Objective-C 2.0, implemented with a patched version of the Clang/LLVM compiler. It features a streamlined syntax with improved readability and reduced code clutter, as well as new features such as Python-like indentation and a limited form of operator overloading. It is inspired by languages such as Smalltalk and Ruby.
Pythonect is an experimental general-purpose dataflow programming language based on Python. It provides both a visual programming language and a text-based scripting language. The text-based scripting language aims to combine the quick and intuitive feel of shell scripting with the power of Python. The visual programming language is based on the idea of a diagram with “boxes and arrows”.
o42a is a high-level general purpose programming language. It is compiled, statically-typed, prototype-based, logic-driven, and primarily declarative, while the imperative programming style is also supported. A program written in o42a is closer to natural English text than one written in any C-like programming language. The language is designed with programming productivity and code maintainability as main priorities. This achieved by powerful, yet restrained, semantics, and expressive and natural syntax.
CPC (Continuation Passing C) is a programming language designed for writing concurrent systems. The CPC programmer manipulates very lightweight threads, choosing whether they should be cooperatively or preemptively scheduled at any given point; the CPC program is then processed by the CPC translator, which produces highly efficient event-loop code. This approach gives the best both worlds: the relative convenience of programming with threads, and the low memory usage of event-loop code. The semantics of CPC is defined as a source-to-source translation from CPC into plain C using a technique known as conversion into Continuation Passing Style. The current implementation of CPC has been used to write Hekate, a BitTorrent seeder designed to handle millions of simultaneous torrents and tens of thousands of simultaneously connected peers.
