Hey all... I just threw together a quick macro to save some typing when
working with the fields of an object. Disclaimer: this should not be used
in library code, or in anything that will stick around longer than a REPL
session. Hopefully it's self explanatory with this example. Is there a
good home for this? Does anyone want to use it?
julia> type T; a; b; end; t = T(0,0)
T(0,0)
julia> macroexpand(:(
@with t::T begin
a = 1
b = 2
c = a + b - 4
d = c - b
a = d / c
end
))
quote # REPL[3], line 3:
t.a = 1 # REPL[3], line 4:
t.b = 2 # REPL[3], line 5:
c = (t.a + t.b) - 4 # REPL[3], line 6:
d = c - t.b # REPL[3], line 7:
t.a = d / c
end
julia> @with t::T begin
a = 1
b = 2
c = a + b - 4
d = c - b
a = d / c
end
3.0
julia> t
T(3.0,2)
