A program for making font samples that show Unicode coverage of the font and are similar in appearance to Unicode charts. Samples can be saved as PDF or PostScript files.

Software distributions released to the CPAN include a META.json or, for older distributions, META.yml, which describes the distribution, its contents, and the requirements for building and installing the distribution. The data structure stored in the META.json file is described in CPAN::Meta::Spec. CPAN::Meta provides a simple class to represent this distribution metadata (or distmeta), along with some helpful methods for interrogating that data.

Code::Perl allows you to build chunks of Perl code as a tree and then when you're finished building, the tree can output the Perl code. This is useful if you have built your own mini-language and you want to generate Perl from it. Rather than generating the Perl at parse time and having to worry about quoting, escaping, parentheses etc, you can just build a tree using Code::Perl and then dump out the correct Perl at the end.

Use List::Rotation::Cycle to loop through a list of values. Once you get to the end of the list, you go back to the beginning. List::Rotation::Cycle is implemented as a Singleton Pattern. You always just get 1 (the very same) Cycle object even if you use the new method several times. This is done by using Memoize on the new method. It returns the same object for every use of new that comes with the same List of parameters.

Test::Identity provides a single testing function, identical. It asserts that a given reference is as expected; that is, it either refers to the same object or is undef. It is similar to Test::More::is except that it uses refaddr, ensuring that it behaves correctly even if the references under test are objects that overload stringification or numification. It also provides better diagnostics if the test fails.

Pathutil tries to be a faster pure Ruby impelementation of Pathname. It arose out of a need to fix basic problems with Pathname, such as suscepetibility to join overrides, need for automatic encoding, and normalization (for stuff like Jekyll) and the ability to do other safe-style operations in an encapsulated format, like copying files and folders with symlinks but only if they originate from the given root.

Battleships solitaire game with a color point-and-shoot interface in the style of blue and galaxis games (for console). This program allows you to play the familiar Battleships game against the computer on a 10x10 board. The interface is visual and largely self-explanatory; you place your ships and pick your shots by moving the cursor around the `sea' with the rogue/hack motion keys hjklyubn.

The aim of this game is to shoot colored balls so the form similarily colored groups, causing them to fall out of the screen. You can either win by clearing your entire field, or lose if any balls attach below the white line near the bottom. The main difference between this game and the classic Bust a Move, is online multiplayer support, with menu options for playing against random opponents, or starting or joining a named (private) game.

This is a small utility for checking and repairing the qmail queue structure. It will fix uid/gid settings and permissions. It will rename the message files to match their inodes. It will even create directories and files that don't exist that should be there (you can even create a queue from scratch). It will also print warnings for any files it finds that should not exist.

The program dvips takes a DVI file [.dvi] produced by TeX (or by some other processor such as GFtoDVI) and converts it to PostScript, normally sending the result directly to the laserprinter. Fonts used may either be resident in the printer or defined as bitmaps in PK files, or a `virtual' combination of both. Dvips will automatically invoke METAFONT to generate fonts that don't already exist.
