Come to think of this. I'm emacs user when comes to lua, lisp, shell scripts, etc. I'm not very good yet, but one thing that puzzles me, is how can I instruct emacs to follow different identation modes for 
parts of the code. Sometimes that code would be in a string.
I'm talking about formatting better my luajit ffi bindings - there you have lua with C mixed.

I am not sure you can cleanly make this a one liner though.


Python 2.5 and later (don't have the older serpents around):

     doThings(x) if x else doThings(y)


An approach I like to solve the problem and make everybody
happy is the one used by the Go language: whitespace is not
significant but there is a canonical indentation style and
a tool (gofmt) that enforces it.


The style used in PiL is a candidate.


I don't see a reason why this wouldn't work with Lua. It is
probably possible to make a parser that takes valid Lua code
and returns a canonical representation for it.


For example: if you make an entry in LuaWiki that contains in
its source
   {{{!Lua
....
}}}
it would not merely highlight keywords as it does now, but also
do the indents.  It would show up canonically, no matter how it
was typed in. Why not?
