在路径中加载所有erlang模块 [英] Load all erlang modules in path

问题描述

使用简单的答案使用螺纹依赖关系加载项目的方法，依赖关系现在可以自动解决，但不会自动加载。

Using the answer from Easy way of loading projects with rebar dependencies, dependencies are now automatically resolved, but they are not automatically loaded.

那么，如何加载所有的模块我的ebin和/ deps / * / bin路径自动？这样他们可以使用Erlang shell选项卡完成，这大大加快了我的开发过程。

So, how can I load all the modules in my ebin and /deps/*/bin path automatically? That way they are available when using the Erlang shell tab completion, which speeds up my dev process considerably.

我的解决方案基于Adam Lindberg的伟大答案： https://gist.github.com/1131312 它只会加载项目模块

My solution based on the great answer of Adam Lindberg: https://gist.github.com/1131312 It will only load the project modules automagically, so almost no delay in erl startup.

推荐答案

这个代码段将会成为诀窍：

This snippet would do the trick:

[code:ensure_loaded(list_to_atom(filename:rootname(filename:basename(F))))
 || P <- code:get_path(), F <- filelib:wildcard(P ++ "/*.beam")].

将其放在您的〜/ .erlang 文件作为一行（包括点：。），它将在启动任何 Erlang shell时执行。请警告，这是非常缓慢的！

Put it in your ~/.erlang file as one row (including the dot: .) and it will be executed upon starting any Erlang shell. Be warned though, it's hideously slow!

» time erl -noshell -s init stop
erl -noshell -s init stop  0.11s user 0.02s system 11% cpu 1.143 total # Without
» time erl -noshell -s init stop
erl -noshell -s init stop  7.31s user 1.08s system 88% cpu 9.480 total # With
