flex.rb is a regexp matching and scanning library for the Ruby language. It is more than 3 times faster than Ruby regexps, and supports matching text arriving in multiple parts (via async, non-blocking I/O). flex.rb embeds the GNU Flex 2.5.4 (fast lexical analyzer generator) as an engine, and all of Flex's functionality is accessible from Ruby scripts.
FreeMarker is a template engine that was originally designed so that servlet-based applications could keep graphical design separate from application logic. The templates provide an easy and highly flexible way to generate any kind of text output (HTML, PostScript, TeX, source code, etc.) from a variety of data sources such as Java objects, Jython objects, XML object models, and more.
QDPF was written to solve the problem of exposing internal services to the Internet. It runs on machines which bridge two networks and forwards TCP/IP packets from one to the other. Its main use is to expose corporate or Intranet services to the Internet, by running it on an intervening machine. TCP sessions can also be followed in detail using the 'trace' option. QDPF is a Java console application.
Text::Template is a module for doing dynamic content generation in Perl. You can embed any Perl code into a file, and then make a call to the module to `fill in' the blanks in the file. This is good for generating HTML pages and form letters. It was first released in 1995 and is very stable, very fast, and very reliable. It is also integrated with Perl's Safe module in case you don't trust the template author.
quote.rb is a Ruby script which defines more than 70 quoters (basic string manipulation routines). Most quoters just add or remove backslashes at the appropriate place; others include hexdumps, checksums, simple encryptions, etc. quote.rb's main goal is to provide all quoters necessary for simple and advanced web programming (CGI and server-side scripting) in one place.
