Free standard portable library 0.1.5 software for linux

Standard Portable Library is a pointer friendly C/C++ STL substitute. The API is similar to Java or .NET and includes common data structures, networking, and database support.

XML Schema Standard Type Library, in short XSSTL, is a collection of universally-useful data types defined in the W3C XML Schema language. The provided types describe concepts such as email address, IP address, phone number, country code, US states, etc.
To make all the types from XSSTL available in your schema simply add the following import directive:
< import namespace="http://www.codesynthesis.com/xmlns/xsstl"
schemaLocation="xsstl.xsd"/ >
And the following namespace-to-prefix mapping to your schema root:
xmlns:stl="http://www.codesynthesis.com/xmlns/xsstl"
Alternatively, you can import individual types:
< import namespace="http://www.codesynthesis.com/xmlns/xsstl"
schemaLocation="xsstl/email-address.xsd"/ >
< import namespace="http://www.codesynthesis.com/xmlns/xsstl"
schemaLocation="xsstl/phone-number.xsd"/ >
Enhancements:
- This initial version includes the following data types: EmailAddress, IPv4Address, Port, IPv4Endpoint, IPv4EndpointStruct, ISO3166CountyCode, Percentage, PhoneNumber, PhoneCountryCode, PhoneAreaCode, PhoneSubscriberNumber, PhoneExtensionNumber, PhoneNumberStruct, RFC822DateTime, USStateTerritoryCode, USStateCode, USTerritoryCode, USContinentalStateCode, and USContiguousStateCode.

Portable Coroutine Library (PCL) implements the low level functionality for coroutines. For a definition of the term coroutine see The Art of Computer Programming by Donald E. Knuth.
Coroutines are a very simple cooperative multitasking environment where the switch from one task to another is done explicitly by a function call. Coroutines are a lot faster than processes or threads switch, since there is no OS kernel involvement for the operation.
Also coroutines require much less OS resources than processes of threads. The idea of writing this library started when I was testing Linux epoll functionality and performance.
I initially started using the coro library by E. Toernig and I found the library very interesting. It was simple and yet powerful. The limitations of the coro library were both non portability and crashes when not used together with certain versions of gcc.
So I decided to write a new library to address the problems aforementioned by also taking portable context switching ideas from the GNU Pth library. This library is easily portable on almost every Unix system and on Windows.
It can use either the ucontext.h functionalities ( getcontext()/makecontest()/swapcontext() ) or the standard longjmp()/setjmp().
Enhancements:
- This release fixes a shared library soname generation error that was missing the library version information.

C++ Portable Types Library (PTypes) is a simple alternative to the STL that includes multithreading and networking. C++ Portable Types Library (PTypes) defines dynamic strings, variants, character sets, lists and other basic data types along with portable thread and synchronization objects, IP sockets and named pipes. Its main `target audience is developers of complex network daemons, robots or non-visual client/server applications of any kind.
PTypes defines simple and intuitive interfaces and differs from the STL in fairly moderate use of templates. The library is portable across many modern operating systems (currently FreeBSD, Linux, SunOS, Mac OS X and Windows). All platform-dependent issues are hidden inside. A simple web server called wshare is included in the package to demonstrate the full power of the library.
And finally, PTypes is open and free.
Main features:
- Threads and synchronization primitives solve the vital problem of diversity of the threading APIs on different platforms. The library also offers message queues and job queues as additional methods of thread synchronization and maintenance.
- IP socket classes and utilities provide complete IP-based framework for both client-side and server-side programming. Combined with PTypes multithreading, these classes can be used for designing complex non-visual applications, such like network daemons or web robots.
- Dynamic strings, variants, character sets, date/time type and various kinds of dynamic and associative arrays: Delphi programmers will find them very similar to the ones in their favorite language. The collection of these basic data types may be useful, among other things, for building compilers and interpreters for higher-level languages.
- Streaming interfaces provide buffered I/O with simple and powerful text parsing methods. A strictly defined syntax for a given text format or a formal language can be represented by calls to PTypes token extraction methods. The unified streaming interface is applicable to files, named pipes and network sockets.
- Special thread class with enhanced functionality called unit. Units have their own main() and input/output plugs; they can be connected to each other within one application to form pipes, like processes in the UNIX shell.
- Finally, everything above is portable: all platform-dependent details are hidden inside.
Enhancements:
- Added support for HP-UX
- Compilation problems solved on *BSD systems (64-bit seek issue)
- Several MacOS X compilation problems solved (socklen_t, libtool)
- MSVC project files are now in the new VC7+ format (.sln, .vcproj)
- Dropped support for BSDi, CygWin and also the Borland C++ compiler.

ustring is a C++ library to implement the complete Unicode 3.0 standard. It gives an easy access to the properties of each of the 10600 characters defined by the Unicode 3.0 standard, including the uppercase and lowercase mapping, category and subcategory, character name, and bidirectional category.

ustring C++ Unicode library provides a wide string class which fits with STL, implementing a full Unicode normalizer, uppercase and lowercase transformation, and diacritical mark removal. A Unicode level-1 regular expression class is also provided.

DM1 Thread Library is part of the DM1 project. This library was born out of my need to have a portable C++ Thread library that would be simple to use, and would provide all the necessary Threads functionality I required for the DM1 project.
Initially, this library was in C, but when I decided to re-write DM1 in C++, I ported the library to C++. During the port, I enhanced the functionality of the Threads library.
The DM1 Threads library aims to be small. It does not try to provide a comprehensive set of functionality, but only what is absolutely essential for a project like DM1. I had the simplicity of the Java Threads package in mind when creating this library.
The constructs provided by the DM1 Thread library are:
- Thread objects that represent Operating System threads.
- A Mutex is provided as a mechanism for Mutual Exclusion . Mutexes are used to ensure that a piece of code is executed by only one thread at any point in time.
- Events are provided as low-level mechanisms for thread synchronisation. Events can be waited for, and signalled to.
- A higher level object, that combines the functionality of an Event and a Mutex, is provided. This is the Monitor object. A Monitor can be locked exclusively, just like a Mutex, but it can also be made the object of a Wait operation. The signalling mechanism supports notification of one or more waiting threads.
- To enable more efficient locking when both shared and exclusive access to data is required, Latches are provided.
- Apart from the Thread synchronisation primitives described above, the library also provides a ThreadPool for the situation when it is inefficient to create a thread exclusively for a particular task, and it is desirable to share a pool of threads for executing multiple tasks.
Design Principles
The DM1 Threads library was designed with the following principles in mind:
1. Implement the bare minimum that is required. This Threads library does not aim to be a comprehensive threads package.
2. Avoid complex algorithms. If a particular construct is hard to implement correctly on all platforms, avoid it.
3. Document the library.
4. Avoid low level code, such as assembler code to implement Spin locks. Rely on the libraries provided by the Operating System.
5. Avoid holding Mutexes beyond function calls. A DM1 Thread library function will not hold any Mutex locks when it returns.
6. Avoid using clever C++ techniques wherever possible. (Unfortunately, some cleverness is required to implement the Thread class correctly).
7. Avoid dependency on external libraries. The DM1 library only requires the standard C library, apart from native Threads functionality.
8. Always report an error as soon as it is discovered.
9. Insert debug messages that can be switched on at run-time.
10. Do not throw exceptions from destructors because these might be executing as a result of an uncaught exception.
11. Never let an error go unreported.

SAgl is a portable small antialiased graphics library. It offers lines, circles, and bezier curves, as well as thick lines and fills.

It can be used on top of SDL or with X or any other graphics system.

The Configuration File Library (CFL) is a collection of routines for manipulating configuration files. The project is a portable library fully written from scratch in pure ANSI C.

It is designed to offer for C programmers common routines for manipulating configuration text files.
