A fun, positional pipe operator >>> for when piping to the first arg just won't cut it.
Bowfish is implemented as a macro. It makes use of the Macro.pipe function called by the standard Elixir forward pipe operator.
import Bowfish
# --- a trivial example ---
"bowfish" >>> String.upcase(:_)
# "BOWFISH"
# --- piping to functions ---
defmodule Test do
def div(a, b), do: a / b
end
4 >>> Test.div(1, :_)
# 0.25
# --- using with an anonymous function ---
add = fn (a, b) -> a + b end
5 >>> add.(1, :_)
# 6
# --- using in a chain ---
add = fn (a, b, c) -> a + b + c end
1 >>> add.(1, 0, :_) >>> Integer.to_string(16, :_)
# "10000"
# --- using with the forward pipe operator ---
add = fn (a, b, c) -> a + b + c end
2
>>> add.(1, :_, 40)
|> Integer.to_string()
|> String.codepoints()
|> Enum.reverse()
>>> Enum.concat(["1","2"], :_)
# ["1","2","3","4"]Available in hex. The package can be installed as:
-
Add bowfish to your list of dependencies in
mix.exs:def deps do [{:bowfish, "~> 0.1.0"}] end
-
Import bowfish in your module.
This really doesn't merit one... but in case that's some kind of sticking point: MIT.
