Free ruby native compiler software for linux

Ruby Time Tracker is a stable and complete time tracking system for small businesses that invoice for time spent by several employees on many projects.

Future Plans

Planned upgrades include:

Locking down past periods so that no entries can be made or changed after invoicing
Custom periods so that users may define billing cycles for thier company
Reminders sent to employees who have not made entries daily or at the end of a billing cycle

Two Versions

There are currently two versions in development. The professional version uses a MySQL database and requires some knowlege of installing and configuring Ruby on Rails applications to install. The lite version includes an installer that will install and configure an SQLight database and a webrick web server for easy installation. Development is being done on the professional version and periodically the lite version will be updated to include new functionality.

Ragel State Machine Compiler compiles finite state machines from regular languages into executable C/C++/Objective-C code. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language.
Ragel can also be thought of as a finite state transducer compiler where output symbols represent blocks of code that get executed instead of written to the output stream.
When you wish to write down a regular language you start with some simple regular language and build a bigger one using the regular language operators union, concatenation, kleene star, intersection and subtraction.
This is precisely the way you describe to Ragel how to compile your finite state machines. Ragel also understands operators that embed actions into machines and operators that control any non-determinism in machines.
Ragel FSMs are closed under all of Ragels regular language, action specification and priority assignment operators. This property allows arbitrary regular languages to be described. Complexity is limited only by available processing resources.
For example, you can make one machine that picks out specially formatted comments in C code, another machine that builds a list all function declarations and a third that identifies string constants then "or" them all together to make a single machine that performs all of these tasks concurrently and independently on one pass of the input.
Main features:
- Describe arbitrary state machines using regular language operators and/or state tables.
- NFA to DFA conversion.
- Hopcrofts state minimization.
- Embed any number of actions into machines at arbitrary places.
- Control non-determinism using priorities on transitions.
- Visualize output with Graphviz.
- Use byte, double byte or word sized alphabets.
- Generate C/C++/Objective-C code with no dependencies.
- Choose from table or control flow driven output.
Enhancements:
- The documentation and the Ruby code generator were improved.

Scriptol to binary Compiler is a C++ native compiler.

Installation:

It is better to install Scriptol at root of a disk, for example:
c:scriptolc

Once the archive is extracted into the scriptolc directory, you have just to change to this directory to run the compiler.

To use the compiler at command line from any directory, you have to put the compiler into the path variable.

The setup script installs required file into sub-directories, or into the directory given as argument. Before to use the compiler, you have to read the licence, in the doc
directory: licence.html.

Usage:

Just type:
./solc mysource

Type "solc" only to list the options.

If your program is a multi-file project, the source given as parameter must be the main source file, the compiler will know dependencies from "include" statements and will build what is needed.

Exemples:

Type from the main scriptol directory:
./solc -bre demosfibo

Configuring:

By editing the solc.ini file, you may change the second pass compiler (you may have to rebuild the libsol library for this compiler), change the options of the compiler or add header files to include.

To add header files, just add "header=someheader.hpp" lines into the config file.

A xxx.cfg file may be written for each project main source beeing xxx, and if present, it overloads the solc.ini file.

4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler.
4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports over 85% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, recursion, include files, etc.
It comes with an RPN calculator, line editor, compiler, decompiler, C-source generators, and a virtual machine.
Enhancements:
- More CORE words and most of the DOUBLE wordset are supported.
- Output buffers can be flushed.
- An experimental multitasking environment was added.

Mumps is a general purpose programming language that supports a native hierarchical data base facility. It is supported by a large user community (mainly biomedical), and a diversified installed application software base. The language originated in the mid-60s at the Massachusetts General Hospital and it became widely used in both clinical and commercial settings. A dwindling number of implementations exist for the language. There are both ANSI, ISO (ISO/IEC 11756:1992) and DOD approved standards for Mumps.

As originally conceived, Mumps differed from other mini-computer based languages of the late 1960s by providing: 1) an easily manipulated hierarchical (multi-dimensional) data base that was well suited to representing medical records; 2) flexible string handling support; and (3) multiple concurrent tasks in limited memory on very small machines. Syntactically, Mumps is based on an earlier language named JOSS and has an appearance that is similar to early versions of Basic that were also based on JOSS.

This translator implements much of the most recent Mumps standard (see the manual). Mumps programs are translated to standard C++ programs and subsequently compiled to binary executables. This distribution contains the compiler source code, the manual, the run-time functions source code, all written in C/C++, and examples, written in Mumps. Also included is a stand-alone Mumps Interpreter for Windows XP and Linux. Click here for additional details.

The MDH (Multi-Dimensional and Hierarchical Data Base Toolkit) is a Linux-based, open sourced, toolkit of portable software that supports very fast, flexible, multi-dimensional and hierarchical storage, retrieval and manipulation of data bases ranging in size up to 256 terabytes. The package is written in C and C++ and is available under the GNU GPL/LGPL licenses in source code form. You must install the Mumps Compiler in order to use the MDH.

Scriptol to Php Compiler is a scriptol program that may be interpreted by the Php interpreter and it may be also compiled either to C++ or directly as an executable.

The Php interpreter is required by solp (download it at www.php.net or get it on the Scriptol CD).

Installation:

It is better to install Scriptol at root of a disk, for example:
/home/user/scriptolp

Once the archive is extracted into the scriptolp directory, you have just to go to this directory from the console to run the compiler.

To use the compiler at command line from any directory, you have to put the compilers into the path, in the usr directory for exemple, or any directory assigned to the path variable (see .bashrc or equivalent). You may also add the scriptol directory to list of paths. Before to use the compiler, you have to read the licence, in the doc directory: licence.html.

Usage:

Type the source of your program in a text editor and save it as mysource.sol or any other name with the sol extension.

Then just type:

./solp mysource

To know the compilers options, type solp without argument, at command line.

Examples:

Type from the main scriptol directory:
./solp demos/helloyou

Portable Object Compiler project consists of a set of Objective-C class libraries and a precompiler (translator) that generates plain C code.
Main features:
- Easy to install or to modify.
- Works on many systems with the native cc, debugger, profiler etc. (Unix, Windows, Macintosh, Beos, OpenVMS etc. see Platforms.txt file)
- Option for reference counted memory management (-refcnt). This uses the native malloc(), free() etc. but the compiler generates statements for keeping track of references (Tested on a few platforms, such as IRIX 5.2 with the SGI malloc).
- Built-in possibility of tracing Objective C messages. (OBJCRTMSG)
- Straightforward "C" messenger; "inline cache" messenger. Forwarding C messenger (to support -doesNotUnderstand:).
- All classes get a +initialize message at start-up, rather than each class receives a +initialize before it receives its first message.
- Some support for translating Objective-C to Smalltalk (-st80 option)
- Automatic archiver. Compiler generates code for classes to save and load objects to and from disk (for all instance variables of type "id").
- Option for Garbage Collection (using Boehm gc package). Tested on some UNIXes and WIN32. Option for reference counted memory management (doesnt require Boehm).
- Exception handling scheme (using Objective-C Blocks) that allows to specify a default handler to be executed.
- Supports dynamically loading Objective-C modules on Windows, FreeBSD, HP-UX, Linux, IRIX, Digital Unix etc.
- Has a switch for double indirection for Object identifiers (id as a handle instead of a pointer). (-become: method)
- Supports forwarding messages (-doesNotUnderstand: method)
- Support for Embedded SQL in Objective-C (Informix only for now)
- Great system for experimentation with your own additions/extensions to Objective C !
