有没有办法在 erlang 中使用 rebar3 创建“.ez”文件？

Question

I know that the support for loading code from archive files is experimental .

An archive file for an application can, for example, be created like this:

zip:create("mnesia-4.4.7.ez",
    ["mnesia-4.4.7"],
    [{cwd, code:lib_dir()},
     {compress, all},
     {uncompress,[".beam",".app"]}]).

But is there any way create ".ez" file using rebar3 conveniently?

Answer 1

This rebar3 plugin worked for me. Here's the basic steps.

1. Add an entry for rebar3_archive_plugin to the plugins entry of your ~/.config/rebar3/rebar.config file (I showed git below but I think its in hex too).

{plugins, [
  {rebar3_archive_plugin, {git, "git@github.com:deadtrickster/rebar3_archive_plugin.git", {branch, "master"}}}
]}.

2. Cd to the app directory and run rebar3 archive

Alternatively, you could add the rebar3_archive_plugin entry to the rebar.config of each app that needs to be archived. For my personal build machine I prefer the first approach because it works for all apps. However, the alternate approach may be preferable if you are trying to do this from an automated build system or the main rebar.config file isn't in your control.
