Open Source Compilers

Protocol Buffers are Google’s fast and simple, language- and platform-neutral, extensible mechanism for serializing structured data. It allows you to define how your data should be structured once, and then using a special generated source code, you can then easily write and read your structured data to and from a variety of data streams and using a variety of languages. Protocol Buffers currently supports a wide array of languages, including C++, Java, Python, Ruby, and many others with more to come.

gputils is a collection of tools for Microchip PIC microcontrollers. Its goal is to be fully compatible with Microchip's tools, MPASM, MPLINK, and MPLIB.

ASN.1 types and codecs (BER, CER, DER) implementation in Python programming language. A collection of various ASN.1-based protocols data structures is supplied in a dedicated Python package. Project moved to GitHub: https://github.com/etingof/pyasn1

PHDL is an HDL that functions as an alternative to mainstream graphical schematic capture tools. The language is compiled into a pcb netlist which can then be imported into a layout tool. We are currently on version 2.1 of the tool. We have created an eclipse plugin version of the tool as well as a standalone command-line based version. Both function identically and output a netlist that can be imported into a pcb layout tool. VHDL revolutionized how FPGA designs and digital logic circuits have been designed and captured and overcame many of the difficulties associated with the use of schematic editing tools. We believe the use of an HDL is also the way of the future when it comes to PCB design. The PHDL compiler automatically supports the output of PADS and Eagle netlists, and through extending a simple java class, users can generate a netlist in practically any format required by their choice of a layout tool.

The Language Machine is a toolkit for language and grammar: a library, main program, and self-hosted rule compilers with one frontend. The system is easy to use. It directly implements unrestricted rule-based grammars with actions and external interfaces.

UIMP(Unified Image Manipulation Program) is an OS independent Image Processing system, which provides over 1000 algorithms and supports web online, console and GUI program.

IvmaiAsn ASN1/ECN/XDR Tools. A collection of the ASN.1/ECN parser, XDR-to-ASN.1 converter and pretty-printer scripts for ASN.1/ECN specifications. Contains also a formal definition of the ASN.1 built-in types, ECN encoding classes and XDR encodings.

The Introspector enables the programming tools that deal with source code such as the compiler to communicate in a standard and neutral manner reducing the accidental cost of programming. http://github.com/h4ck3rm1k3/

dxcut is a library for reading, editing, and writing dex and odex files which contain the class definition and Dalvik bytecode used by the Android operating system. This project includes a disassembler/decompiler, dex optimizer, and hooking utils.

latexcalc is a "LaTeX Calculator" that calculates values inside your LaTeX files before typesetting them. More accurately, it preprocesses files written in a superset of the LaTeX typesetting language and evaluates specified expressions in the text.

ByteML is a XML-JavaBytecode interoperability framework. With the aid of this framework the end-user can convert bytecode ( Java .class files ) to XML files and vice-versa.

ConvertMake is a developer tool for Mac OS X that converts command line build systems into Apple's Xcode .xcodeproj project format.

flatcc has no external dependencies except for build and compiler tools, and the C runtime library. With concurrent Ninja builds, a small client project can build flatcc with libraries, generate schema code, link the project and execute a test case in a few seconds, produce binaries between 15K and 60K, read small buffers in 30ns, build FlatBuffers in about 600ns, and with a larger executable also handle optional json parsing or printing in less than 2 us for a 10 field mixed type message. The JSON parser may change the interface for parsing union vectors in a future release which requires code generation to match library versions. This project builds flatcc, a compiler that generates FlatBuffers code for C given a FlatBuffer schema file. This introduction also creates a separate test project with the traditional monster example, here in a C version. The setup script builds flatcc using CMake, then creates a test project directory with the monster example.

A project to develop a tool converts Intel IHEX format or other to machine-depend format. Basically it intends to help cross compiling environment for old-time 8-bit computers.

JAXX is a powerful XML user interface language for Java. JAXX source files compile into ordinary Java classes, making integration a snap. JAXX features advanced data binding and event handling, and uses (fully compiled) Java as its scripting language

L2jdertin, Stable L2J Cliente: Interlude.

Libraries and tools for compiling and text processing, written in Dylan using XML-based literate programming techniques.

pyxser stands for python xml serialization and is a python object to XML serializer that validates every XML deserialization against the pyxser 1.0 XML Schema. pyxser is written entirely in C as a python extension.

Abacus Technologies Relational XQuery is an XQJ compatible XQuery processor that provides the ability to execute XQuery against both relational and XML data sources. Relational data can be transformed to any XML schema using XQuery's powerful features.

Compiler and interpreter for the Scriptol programming language. Scriptol is object oriented and the first language to use XML as data structure in sources. It is easy to learn and safe. Also, RSS readers in PHP, an RSS feed editor.

Toolset for the TMPL (Template Matching Processor Language). Compiler and runtime for creating/ evaluating templates on XML data streams. Can be integrated easily in Java projects.

Templification - Keeping templates simple and efficient. PHP Precompiled Templates for faster production server operation and more efficient use of memory. Encourages better design models, too! Incredibly easy to Drop In Place in existing solutions.

The VSR is a repository of tools and challenges in verification (see for example epubs.cclrc.ac.uk/work-details?w=33971). It is part of the international grand challenge on software verification (eg http://vstte.ethz.ch/pdfs/vstte-hoare-misra.pdf)

What is a domain-specific language intended for constructing web services on top of ordinary web pages, or otherwise automate web-related tasks. Using a powerful pattern matching sublanguage, What strives to be for XML/HTML what Perl is for text analysis

XIPL/XASM is a basic environment to build high-level Image Processing operations using a XML-based language. The idea is to compile the high-level XIPL language into a low-level one, XASM (XML-based too), using XSLT technology.
