The library also offers message queues and job queues as additional methods of thread synchronization and maintenance.</p>  </li>  <li>    <p> 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.</p>  </li>  <li>    <p> 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.</p>  </li>  <li>    <p>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.</p>  </li>  <li>    <p>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.</p>  </li>  <li>    <p>Finally, everything above is portable: all platform-dependent details      are hidden inside.</p>  </li></ul><p><b><br>  Why use PTypes?</b></p><blockquote>  <p>PTypes is yet another generic class library among tens and hundreds of others.    To find its own niche in this variety of generic programming tools we decided    to emphasis on simplicity of the interfaces and readability of the resulting    code (i.e. the code that uses the library). The library focuses    only on most widely used data types and functional interfaces. We think that    like programming languages themselves, low-level libraries, too, should use    the minimal set of notions for covering most programming patterns.</p>  <p>Some data types in the library (strings, character sets and variants) use algebraic notation rather than object-oriented, i.e. you write <span class="lang">length(s)</span> for a string object instead of <span class="lang">s.length()</span>. We believe that traditional notation better fits to a class that represents some fundamental notion and is not supposed to produce subclasses with overridden methods. In other words, if there is no inheritance and polymorphism, there is no need for method calls as well.</p>  <p>PTypes uses old-fashioned all-lowercase naming style, since it  can   peacefully co-exist with other styles in one program. Whether you are a `unixoid'   or you are using modern writing styles (Hungarian, Borland, etc.) you can   combine your favorite style with PTypes with no or very little  harm to your   source code.</p>  <p>And finally, in order to achieve better readability of the resulting    code we use    clean    class    naming,     i.e. the string type is called <span class="lang">string</span>, thread     is <span class="lang">thread</span>,     etc.</p>  <p>We designed this library in the hope that PTypes with its conciseness and    intuitiveness could find its own 'target audience'.</p></blockquote><p><br>  <b>Versions and availability</b></p><blockquote>  <p>Version 2.0 of PTypes is the tenth public release. The third number in the version indicates insignificant improvements or bug fixes. You might want to take a look at the <a href="changes.html">Changes</a> page if you are familiar with one of the previous versions.</p>  <p>The latest source code and both on-line and out-of-line documentation can be found at</p>  <blockquote>    <p><a href="http://www.melikyan.com/ptypes/">http://www.melikyan.com/ptypes/</a></p>  </blockquote>  <p>You can receive announcements about new releases through one of the following    services:</p>  <blockquote>    <p><a href="http://freshmeat.net/projects/ptypes/">Subscribe to the project        at freshmeat.net</a><br>        <a href="http://sourceforge.net/projects/ptypes/">Monitor the project        at SourceForge.net</a></p>  </blockquote>  <p>The development version of PTypes is available at SourceForge.net's CVS server. If you are willing to join the development of the library, please become a SourceForge.net user and then contact me to get full access to the CVS repository. The file TODO in the development branch contains the immediate development plan for the library.</p></blockquote><p><br>  <b>Bugs and known problems</b></p><blockquote>  <p>The list of problems encountered in the latest version along with their    solutions, if available, can be found at PTypes project management page (at    SourceForge.net):</p>  <blockquote>    <p><a href="http://sourceforge.net/projects/ptypes/">PTypes project management        page</a></p>  </blockquote></blockquote><p><b><br>  Contributors</b></p><blockquote> <p>We would like to thank:</p><blockquote><p>Pierre-Frederic Caillaud &lt;peufeu at free dot fr&gt;<br>Ralph Siemsen &lt;ralphs at netwinder dot org&gt;<br>Marco Geri &lt;m.geri at list dot it&gt;<br>Philippe Le Rohellec &lt;plerohel at hotmail dot com&gt;<br>Mark Lentczner &lt;markl at glyphic dot com&gt;<br>Jordan Ritter &lt;jpr5 at darkridge dot com&gt;<br>Sergey Matveychuk &lt;sem at ciam dot ru&gt;</p></blockquote></blockquote><p><b><br>  Contacts</b></p><blockquote>  <p>PTypes is open and free, which also means it is open to your comments and    suggestions.
