In the company I'm working for there are still lots of components in pure Erlang, and those Erlang packages are installed globally under /usr/lib/erlang/lib/... by a Linux package manager like yum; Managing packages dependencies is not a big deal here I would say, even without yum; With switching to Elixir doesn't mean we have to rewrite all components in Elixir, a consensus here is only when rewriting is proven to have superior benefits; so here why not give user freedom to manage global packages? not restricting user have to make a fake project to evaluate something; here benchee is used as a global package and doesn't belong to any particular project, don't even want to add into mix.exs The current requirement of mix to install a package within a project is just odd to people with different language background This is the proposal: $ mix install benchee --save # install the package to current project, `--save` option is optinal, inspired from `npm install`, which does add the new dependency to its package.json; for mix this can be added into mix.exs $ mix install benchee --user # install into a hidden directory under user's home, this works for a user with ERL_LIBS properly set; this is pip's behavior $ sudo mix install benchee --global # install globally to where Elixir or Erlang's system libs (that is /usr/lib/erlang/lib to Erlang usually) -- You received this message because you are subscribed to the Google Groups "elixir-lang-talk" group.
