Yichao, why is it bad idea to splat? Is it not performant? El jueves, 24 de diciembre de 2015, 5:02:14 (UTC-6), Min-Woong Sohn escribió: > > I want to reduce the amount of memory used by a dataframe that has lots of > binary variables. What is the best way to achieve this? For example, how >

[julia-users] Re: Using macros to override lots of operators for a user-defined type

You could also use a macro: module MetaFoo export Foo, ops, @foo_op type Foo{T<:Number} x::Vector{T} end const ops = [+, -, *, /] const syms = [symbol(op) for op in ops] for sym in syms dot_sym = symbol(".$sym") docstr = "`$sym` also works for `Foo` types!" @eval begin

[julia-users] Re: Using macros to override lots of operators for a user-defined type

It's nice how does @show works! It returned a tuple because I made a mistake, without it, it looks like this: julia> macro foo_op(op) quote dot_op = symbol(".$($op)") docstr = "`$($op)` also works for `Foo` types!" @show $op typeof($op)

[julia-users] Re: Using macros to override lots of operators for a user-defined type

Thanks to Michael's example, I did this other version of the macro: julia> type Foo{T<:Number} x::Vector{T} end julia> macro foo_op(op) quote dot_op = symbol(".$($op)") docstr = "`$($op)` also works for `Foo` types!"

Re: [julia-users] Re: Using macros to override lots of operators for a user-defined type

I didn't know of "$($x)" to interpolate inside stirng inside expresion, thanks! This also works: macro foo_op(op) quote dot_op = symbol(".$($op)") docstr = "`$($op)` also works for `Foo` types!" function Base.$op(a::Foo, b::Foo) Foo(dot_op(a.x, b.x))

[julia-users] Re: Using macros to override lots of operators for a user-defined type

I haven't been able to figure out how to make it work inside a for loop though: julia> for op in [+, -] @foo_op op end ERROR: UndefVarError: op not defined [inlined code] from none:5 in anonymous at no file:0 julia> macro foo_op(op) quote dot_op =
