This repository contains the LDPL Standard Library, a collection of LDPL libraries that contain many useful pre-written statements for the LDPL Programming Language that are not included in the base language.

The library is organized in a series of .ldpl files lovingly called briefcases (this is a very serious language, you know, we have ties) each containing new statements designed to extend the functionality of LDPL in many areas. In simpler terms, designed to make your life as an LDPL programmer easier. For example the brc_lists.ldpl briefcase includes many statements designed for working with LIST values, like FLIP LIST and SORT LIST - ASCENDING.

New statements and entire briefcases are very welcome contributions, corrections and feedback are most certainly welcome as well.

Most of the time you won't need the entire Standard Library for a single project, so you can just get the briefcases you are going to use. You can do this by hand or using LPM (the LDPL Package Manager).

Open a terminal and write lpm install <briefcase-name> to install the desired briefcase. Available briefcases are std-list (list statements), std-math (math statements), std-text (text statements), std-os (operating system functions) and std-random (random number generation and statements).

For example: lpm install std-random.

To include the downloaded briefcase in your project add the line USING PACKAGE <briefcase-name> before the DATA: and PROCEDURE: sections.

For example: USING PACKAGE std-random.

Just download the briefcase you want and include it in your LDPL source file. For example, if you want to include the file std-lists.ldpl you should add the line

INCLUDE "/route/to/std-lists.ldpl"

before the DATA: and PROCEDURE: sections.

Every statement is documented in more detail within its own briefcase file.
