The objective of APL-Library is to provide a collection of APL
libraries that provide much of the functionality of other scripting
languages.
APL is a functional programming language originally proposed in the
1950s and implemented by IBM in the 1960s. Several APL interpreters
are available see http://www.sigapl.org/. These workspaces were
developed in GNU APL (http://ftp.gnu.org/gnu/apl).
APL uses a suite of operators and functions represented by special
characters and many APL vendors use proprietary file formats. Files
in the library are utf-8 encoding where APL's special characters are
stored with their Unicode value.
To display these files one must have an appropriate font installed.
The Free Software Foundation offers one at http://ftp.gnu.org/gnu/unifont/
As the standard computer keyboard does not contain many of these
special APL characters you must reconfigure yours and you have many
options. File README-3-keyboard distributed with GNU APL offers many
ideas. I used Emacs and gnu-apl-mode.
Open file apl-library.info by entering info path/to/apl-library.info
at the shell prompt.
Many of these libraries depend on workspace FILE_IO.apl shipped with
gnu-apl. This workspace has recently been updated and you may need
functions not available in prior releases of gnu-apl. Source code for
gnu-apl (and workspace FILE_IO.apl) is available at
http://savannah.gnu.org/projects/apl.
