我知道IEx.pry
当你运行像iex -S mix
.
我正在做一些不使用混合的长生不老药练习。我使用elixir myfile.exs
.
如何使用 IEx 运行此文件,以便可以IEx.pry
在应用程序中使用断点?
编辑:这里是文件:
# hello_world.exs
defmodule HelloWorld do
@doc """
Greets the user by name, or by saying "Hello, World!"
if no name is given.
"""
@spec hello(String.t) :: String.t
def hello(name \\ "World") do
"Hello, #{name}!"
end
end
# hello_world_test.exs
if !System.get_env("EXERCISM_TEST_EXAMPLES") do
Code.load_file("hello_world.exs", __DIR__)
end
ExUnit.start
ExUnit.configure exclude: :pending, trace: true
defmodule HelloWorldTest do
use ExUnit.Case
test "says hello with no name" do
assert HelloWorld.hello() == "Hello, World!"
end
end
输出:
