Folks, I really like the LuaMacro
extension(http://lua-users.org/wiki/LuaMacros) and I'd like to use it
to simplify some of my AI scripts.
However while I do understand simple examples of its usage I can't
wrap my head around more complicated scenarios :(
Basically I have the following Lua code(it's a piece of some AI
behavior tree logic):
parallel(function (self)
self:add(sequence(function (self)
self:add(Foo())
self:add(Bar())
end))
end)
... which I'd like to rewrite using LuaMacro as follows:
PARAL(
ADD(SEQ(
ADD(Foo())
ADD(Bar))
))
)
I started with PARAL trying to implement it as follows:
def('PARAL', {'body';handle_params = true},
'parallel(function(self) body end)'
)
However the simple test script using this macro yields an error:
local f = PARAL(
function(self) end
)
$ lua -lmacro test.lua
lua: test.lua:6: '<name>' expected near '('
I know how I would write these macro in plain C but can't write
similar stuff using LuaMacro. Help me please :)
