Leo: Leonine Editor with Outlines

Project description

Leo is:

  • An outliner. Everything in Leo is an outline.
  • A Personal Information Manager.
  • A browser with a memory.
  • A powerful scripting environment.
  • A tool for studying other people’s code.
  • A fully-featured IDE, with emacs-like commands.
  • Extensible via a simple plugin architecture.
  • A tool that plays well with IPython, vim and xemacs.
  • Written in 100% pure Python
  • Compatible with Python 2.6 and above or Python 3.0 and above.
  • A tool with an inspiring and active community.

Leo’s unique features

  • Always-present, persistent, outline structure.
  • Leo’s underlying data is a Directed Acyclic Graph.
  • Clones create multiple views of an outline.
  • A simple, powerful, outline-oriented Python API.
  • Scripts and programs can be composed from outlines.
  • Importers convert flat text into outlines.
  • Scripts have full access to all of Leo’s sources.
  • Commands that act on outline structure. Example: the rst3 command converts outlines to reStructuredText.
  • @test and @suite scripts create unit tests automatically.
  • @button scripts apply scripts to outline data.
  • Outline-oriented directives.

Simulating these features in vim, Emacs or Eclipse is possible, just as it is possible to simulate Python in assembly language…
