http://webpages.charter.net/edreamleo/intro.html

Leo 4.10 contains 9 months of intense work on Leo. Several very important
features are subtle; you could almost call them Easter Eggs, so please read
the following notes carefully.

The highlights of Leo 4.10:
---------------------------

* Dozens of new and improved features and commands, including...
- Tab completion now shows all @command & @button nodes.
- Leo tabs may be detached from the main window.
- The Open With menu now works.
- The leoInspect module answers questions about Python code.
- Leo can highlight the pane containing the focus.
- The bigdash plugin searches across multiple files.
- Improved abbreviation capabilities.
- Improved handling of URL's.
- Improved editing of non-Leo files.
- Improvements create "weightless" unit testing.
* Easier installation on MacOS.
* Fixed almost 70 bugs.

The Easter Eggs
---------------

1. Tab completion now shows all @command & @button nodes.

Put all your common scripts in @command nodes in myLeoSettings.leo.
Typing @c will remind you of the names of these scripts.
You can execute the scripts by name without the "@command-" prefix.

2. Improved abbreviation capabilities.

Virtually any kind of abbreviation is possible. For example, ~a to ã.

3. Improved handling of URL's.

URL's can link to other Leo outlines. Ctrl-Click on nodes or URL's
in body text to activate the URL.

4 Weightless unit testing.

The mantra is edit, alt-4 (run-marked-unit-tests-externally), edit,
alt-4,... Several seemingly innocuous changes made this work without an
"friction". The result is a remarkable increase in productivity.

Coverting Leo to Python 3k: goals

This is the first in a series of posts that will describe how I am converting my Leo app to run on Python 3k. I will be writing these posts before the project is complete so that the details are fresh in my mind. But the intention is to say something that will be generally useful to anyone contemplating a similar project: I'll keep Leo-specific details to a minimum. My emphasis will be on strategy and tactics, not code-level details.

The one and only goal of this project is straightforward: the final product will be code that compiles and runs on both Python2k and Python3k without any modification whatsoever. A common code base is an absolute requirement, for two reasons:

1. Leo is under active development using bzr. It would be intolerable to attempt to support multiple code bases for any length of time.

2. Python's 2to3 code-conversion tool does not begin to have the sophistication needed to automatically convert Leo's code. But even if 2to3 did have the smarts, it would odious to add an intermediate code-conversion step every time anyone changed Leo's code base.

This goal is just a bit ambitious, but I have absolute confidence that it can be accomplished. I'll tell you why in the next post.
