-- DaVinci is an IDE for Lua based on SciTe, IUP, and Ldb.
-- See the project page (link above) for more information.
-- The main idea of this file is that if we put this in our 
-- ~/.SciTEUser.properties file,
--  
--   command.2.*=dostring dostring(editor:GetSelText())
--   command.name.2.*=lua-dostring
--   command.mode.2.*=savebefore:no
--   command.subsystem.2.*=3
--
-- then we can mark a region of text in SciTe, with, say,
-- shift-arrows, and when we press Ctrl-2 SciTe will execute
-- it in the Lua interpreter that it links in.
-- This is an e-script. The idea is the same as in:
--   http://angg.twu.net/eev-article.html
--
error('"intro.lua" is to be executed with lua-eval-region, not at once.')

-- Which version of Lua do we have?
-- SciTe 1.74 comes with Lua 5.1, older ones came with Lua 5.0.
print(_VERSION)          --> print: output in the output pane
io.write(_VERSION.."\n") --> io.write: output on stdout
io.flush()               --> flush stdout



-- (find-luamanualw3m "#pdf-file:setvbuf")
io.stdout:setvbuf("no")  --> make io.flush() unnecessary (Lua 5.1 only)
-- Load several convenience functions.
