Pure Language and Library Documentation

Last updated: October 23, 2014 (v0.63)

This manual collects all of Pure’s online documentation: The Pure Manual which covers the Pure language and the operation of the Pure interpreter; the Pure Library Manual which describes the standard library modules included in the distribution of the Pure interpreter; all available documentation for the various addon modules which can be downloaded as separate packages from the Pure website; and an appendix with installation instructions and additional information for Windows users.

Most of the Pure documentation is distributed under the GNU Free Documentation License. The authors of the current edition are listed below. (This just lists the primary section authors in alphabetical order; please check the different parts of this manual for additional authorship and licensing information.)

The Pure programming system is free and open source software. The interpreter runtime, the standard library and most of the addon modules are distributed under the GNU Lesser General Public License or the 3-clause BSD License which allow for commercial applications. Some parts of the system also use the GNU General Public License (typically because they interface to other GPL’ed software such as Gnumeric, GSL and Octave). Details about authorship and license conditions can be found in the sources or in the various manual sections.

From the Pure website you can also download a recent version of this manual in pdf format.
