Package format

A package format is a type of archive containing computer programs and additional metadata needed by package managers. While the archive file format itself may be unchanged, package formats bear additional metadata, such as a manifest file or certain directory layouts. Packages may contain either source code or executable files.

Packages may be converted to one type to another with software such as Alien.

Format (Common Lisp)

FORMAT is a function in Common Lisp that can produce formatted text using a format string similar to the printf format string. It provides more functionality than printf, allowing the user to output numbers in English, apply certain format specifiers only under certain conditions, iterate over data structures, and output in a tabular format. This functionally originates in MIT's Lisp Machine Lisp, where it was based on Multics ioa_.

Example

An example of a C printf call is the following:

Using Common Lisp, this is equivalent to:

Another example would be to print every element of list delimited with commas, which can be done using the ~{, ~^ and ~} directives:

Note that not only is the list of values iterated over directly by FORMAT, but the commas correctly are printed between items, not after them. A yet more complex example would be printing out a list using customary English phrasing:

Whilst FORMAT is somewhat infamous for its tendency to become opaque and hard to read, it provides a remarkably concise yet powerful syntax for a specialised and common need.

Package (OS X)

In the Apple OS X operating system, a package is a file system directory that is normally displayed to the user by the Finder as if it were a single file. Such a directory may be the top-level of a directory tree of objects stored as files, or it may be other archives of files or objects for various purposes, such as installer packages, or backup archives.

Definition

The package is a common file system abstraction used by Apple operating systems, such as OS X and iOS. It is a directory that may contain a hierarchy of files or objects that represent a preserved, organized state. A package is displayed to users like a single file in the Finder application to avoid being changed by the user. However, the content of packages may be accessed through special keyboard and mouse combination events. For this purpose, the control-click, or right-click, menu displays a directive Show Package Contents.
