Library_Maker

A Library Maker is any tool designed for creating and editing
Libraries for Game
Maker and/or LateralGM.

Generally, it deals with files of the following formats:
LIB and LGL.

Currently, two Library Makers are publicly available:

• The official YoYo Games Library
  Maker (included with the
  Extension Maker) which is only capable
  of working with LIBs.

• The unofficial LateralGM
  LibMaker capable of working
  with LIBs and LGLs, as well as saving older LIBs.

LateralGM LibMaker

We strongly recommend this version, as it is capable of reproducing all
of the functionality of the official Library Maker, but has better
support and more features.

Philosophy features:

• Cross platform - You can run it on Win, Mac, and even Linux.
• Open source - Other people can look over the code, and even edit it
  and contribute to it.
• Actively Supported - The official Makers are not supported by
  YoYo Games. The unofficial LibMaker is supported by the LateralGM
  team, and our community (the ENIGMA forums). We are glad to answer
  questions, take input and feedback, and even modify/update the
  project to your needs.

Program features:

• Cleaner interface
• Modular interface, makes what you see very easy to modify, swap out,
  or entirely replace while maintaining the basic functionality of the
  program.
• Action Preview, allows you to preview an action as you would see it
  if you edited it in Game Maker.
• Icon Preview, the action list at the left provides little previews
  of each action's icon right there, making it easier to navigate the
  list.
• Syntax Highlighted code editor, powered by
  JoshEdit.
• Ability to save and load both versions of LIB, as well as the tiny
  LGL alternative format (currently LGL is only supported by
  LateralGM).
• Ability to load (and edit) official LIBs.
• Ability to change the Library ID.
