Leo's second tutorial
<http://leoeditor.com/tutorial-pim.html#using-abbreviations-and-templates>mentions
abbreviations, but doesn't indicate how amazingly powerful they are.
Earlier today I realized that almost all of Leo's commands can be executed
as abbreviations!
Rev a002317 tweaks the abbreviation code so that commands that set the
selection range work properly when the abbreviation goes away. For example:
e;;={|{x='';c.k.simulateCommand('end-of-line-extend-selection')}|}
defines the e;; abbreviation so it selects from the cursor position (after
e;; goes away) to the end of the line. Amazing! Similarly:
ee;;={|{x = '' ; c.k.simulateCommand('end-of-buffer-extend-selection')}|}
Notice: ee;; not E;; Much easier to type. Kinda like vim bindings but
without the need to keep hitting escape ;-)
Abbreviations won't work for commands like sort-line that require an
existing selection range, but they probably will work for almost all other
Leo commands.
Abbreviations are full scripting environments. As such, they are a bit of
a security risk (but no more than Ctrl-B). @bool scripting-abbreviations =
True must be in effect to make this all work.
I don't suppose such abbreviations will supplant the minibuffer, but there
are many cases in which they would be useful.
