Ansiprint is a utility for printing text files (or stdin) from remote terminals using ANSI telnet escape sequences. It was inspired by the ansiprt.c component of the University of Washington's excellent email package, PINE. However, since the author believed that ansiprt.c was released under "somewhat ridiculous terms", ansiprint has been completely re-written in C++, and includes a variety of new features.
Anteater is a log analyser for MTA logfiles (such as those produced by sendmail and postfix). The tool is written in 100% C++ and is very easy to customize. Input, output, and the analysis are modular class objects with a clear interface. Currently, there are modules for reading the syslog format of sendmail and postfix that do up to eight useful analyses and write the result in plain ASCII or HTML, to stdout or to files.
Apache Jakarta Regexp is a 100% pure Java regular expression package. Expression syntax supports all of Perl5 syntax, with the exception of back reference substitution markers (several people have mentioned this lack, so please feel free to contribute a solution). It also supports a very limited subset of POSIX features. Performance and features are somewhat inferior to ORO, and the new JDK 1.4 (java.util.regex) package, but the package is especially small and features the ability to precompile expressions (without using object serialization) into byte arrays, thus avoiding the need to load the expression compiler.
Arabeske is a special kind of vector drawing software. It has a limited set of shapes but is extremely specialised towards complex symmetric interlaced drawings, like those traditionally found in Arabic architecture. It is not a texture editor, but rather a pattern generator. It exports in EPS, PNG, and POV-Ray formats.
Arad-OneTable-Editor is a set of perl modules to manage and display a dialog for a single-table SQL query. It can verify types, and scroll between the records. The data handling is separate from the dialog class, so it is possible to write different generic dialogs for the same query. A Perl/Tk dialog and a GNU/readline (or plain text) dialog are included in the distribution.
The Archive::Zip module allows a Perl program to create, manipulate, read, and write Zip archive files without calling an external program. Members can be added, removed, extracted, replaced, rearranged, and enumerated. They can also be renamed or have their dates, comments, or other attributes queried or modified. Their data can be compressed or uncompressed as needed, and members can be created from members in existing Zip files, or from existing directories, files, or strings.
ascii lists ASCII idiomatic names and octal/decimal code-point forms. It provides easy conversion between various byte representations and the American Standard Code for Information Interchange (ASCII) character table. It knows about a wide variety of hex, binary, octal, Teletype mnemonic, ISO/ECMA code point, slang names, XML entity names, and other representations. Given any one on the command line, it will try to display all others. Called with no arguments, it displays a small, handy ASCII chart.
