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.
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.
PYX is a highly simplified XML derivative/substitute suitable for use in certain applications. In particular, PYX markup is easy to parse, and PYX documents are easily processed with simple tools. MyoPyx is a compact PYX document parser with a SAX-like API. Its small size makes it convenient for embedding in other applications who need some form of structured document markup, but don't need the weight of a full XML processor. It provides both Java and Ruby validating, streaming parsers.
glark offers grep-like searching of text files, with very powerful, complex regular expressions (e.g., "/foo\w+/ and /bar[^\d]*baz$/ within 4 lines of each other"). It also highlights the matches, displays context (preceding and succeeding lines), does case-insensitive matches, and automatic exclusion of non-text files. It supports most options from the GNU version of grep.
ZenWeb is a system for building entire Web sites, not just pages. It allows you to focus on the content and the structure of the website, while leaving page construction, markup, layout, and navigation as secondary concerns. It provides tools for complete Web site design and creation, simple paragraph to HTML generation with embellishments, and a rich set of tools for page and Web site creation, modification, and customization.
Ruby/DICT is an RFC 2229-compliant client-side library implementation of the DICT protocol, written in the Ruby programming language. It can be used to write clients that access dictionary definitions from a set of natural language dictionary databases. rdict, a powerful CLI dictionary client built on Ruby/DICT, is included.
For Ruby developers, YAML is a natural fit for object serialization and general data storage, as their semantics are similiar. YAML4R is a fully-featured YAML parser and emitter for Ruby. Use it as a drop-in replacement for PStore, or use one of its several APIs to store object data in the friendly and readable YAML style.
newfile generates "starting-out" files using a full featured template preprocessor. It can also generate trees of files, for example, a FreeBSD port or a project using automake and autoconf. A user can add their own template files and directories to those supplied with the package. It includes templates for making "empty" files for Ruby, make, shell, C, C++, C & C++ headers, and more.
