Here's the link: https://www.leoeditor.com/preface.html https://www.leoeditor.com/preface.html And for those on small screens: -- Leo is: -- * A fully-featured IDE, with many features inspired by Emacs. * An outliner. Everything in Leo is an outline. * A data manager, data manager and personal information manager. * A powerful scripting environment. * A tool for organizing and studying computer code. * Extensible via a simple plugin architecture. * A tool that plays well with IPython, Vim and Emacs. * Written in 100% pure Python -- Leo’s unique features -- Leo completely integrates Python scripting and outlines. Simulating the following features in Vim, Emacs or Eclipse is possible, just as it is possible to simulate Python in assembly language… * All commands and scripts have easy access to outline structure via a simple Python API. For example, p.b is the body text of the selected outline node. Scripts have full access to all of Leo’s sources. * Clones create multiple views of an outline. Leo’s underlying data is a Directed Acyclic Graphs. As a result, Leo organizes data in completely new ways. * Scripts and programs can be composed from outlines using outline-oriented directives. * Importers convert flat text into outlines. * @test and @suite scripts create unit tests automatically. * @button scripts apply scripts to outline data.
