Elixir, how to modify dependency?

Question

我需要将简单的handle_call函数“注入”我的一个依赖项，是否可以在不修改原始依赖项的情况下完成？

Answer 1

I don't think that's possible without modifying it's source. (depends on dep though) I had such problem on hackathon once. I've just forked it's source on github, modified it and replaced the import with git one like that:

{ :foobar, git: "https://github.com/elixir-lang/foobar.git" }

It's a hack, but it works. Please give us more concrete example maybe we can do it another way.
