MaiaEditor is a lightweight and versatile web editor. The only dependency is the Prism library, for syntax highlight. It is the MaiaStudio default editor. MaiaStudio is the MaiaScript IDE.

MaiaScript is a programming language aimed at developing adaptable and intelligent applications. An adaptive application modifies its code to suit the conditions of the environment. An intelligent application, it learns to process the data it receives and adjusts to possible changes in its characteristics, over time. The MaiaScript language implements the adaptation paradigm, combining it with a variation of the object-oriented paradigm, simplified to exclude definitions of types and access restrictions. These characteristics make MaiaScript a programming language suitable for rapid learning, both by Computer Science professionals and scientists who are starting to implement computational algorithms. The characteristics of this language, also allow the rapid development of complex applications, especially when adaptability is necessary. MaiaScript also presents a syntax similar to that used in Mathematics, including libraries for Numerical Calculation, Complex Network Analysis, Database Access, Regular Expression Processing, and an abstraction layer between the MaiaScript interpreter and the underlying Operating System.

MaiaEditor currently implements the following features:

  • Syntax highlighting;
  • Line number display;
  • Auto-indentation;
  • Automatic closing of structures;
  • Indent and unindent method;
  • Comment and uncomment method;
  • Undo and redo;
  • Search and replace text based on regular expressions;
  • Support for any language supported by the Prism syntax highlighter;
  • Lightweight and easily extensible editor;
  • Simplified API, although powerful;
  • Free software.

In addition to being accessible via the API, some commands are available as shortcut keys:

  • [CTRL] + i: indent;
  • [SHIFT] + [CTRL] + i: unindent;
  • [CTRL] + m: comment;
  • [SHIFT] + [CTRL] + m: uncomment;
  • [CTRL] + z: undo;
  • [SHIFT] + [CTRL] + z: redo, or on macOS:
  • [CMD] + i: indent;
  • [SHIFT] + [CMD] + i: unindent;
  • [CMD] + m: comment;
  • [SHIFT] + [CMD] + m: uncomment;
  • [CMD] + z: undo;
  • [SHIFT] + [CMD] + z: redo.
