我把 .beam 当作脚本使用，这样能隐藏代码，并在任何地方运行。
通常会有多个文件一起工作，例如
entry.erl
helper.erl
....能把多个 beam 文件合成一个 beam 吗？
我唯一想到的办法是把 beam 嵌入 erl 文件，然后再编译，例如
["[",
lists:map(fun(Artifact) ->
{ok, Payload} = prim_file:read_file(Artifact),
["{", filename:basename(Artifact, ".beam"), ",", io_lib:format("~w", [Payload]), "},"]
end, Artifacts)
"ok]"]得到
[{module, <<"....">>}]最后通过 code:load_file 加载
I'm treating .beam as a script so I can conceal my code and execute it any where.
Normally several files cooperate, for example:
entry.erl
helper.erl
....Can several beam files be combined into a single beam?
My only idea is embedding the beam inside an erl file before compiling that, for example
["[",
lists:map(fun(Artifact) ->
{ok, Payload} = prim_file:read_file(Artifact),
["{", filename:basename(Artifact, ".beam"), ",", io_lib:format("~w", [Payload]), "},"]
end, Artifacts)
"ok]"]producing
[{module, <<"....">>}]then loading it via code:load_file
这样能隐藏代码，并在任何地方运行
.beam 文件并非完全可移植。Erlang 虚拟机不会接受由更新的 OTP 版本，或者太旧的版本构建的文件。

通常这种情况可以用 escript (https://www.erlang.org/doc/apps/stdlib/escript.html)，它是一种能容纳多个 beam 文件以及 Erlang 运行时的归档格式。Erlang 运行时附带 escript 程序，可以解包并执行这些归档。rebar3 支持构建 escript。

.beam files aren't completely portable. The Erlang VM won't accept files built with a later OTP release, or with a release that's too old.
I'm treating .beam as a script
The usual answer here is escript (https://www.erlang.org/doc/apps/stdlib/escript.html), an archive format capable of holding several beam files together with an Erlang runtime. The Erlang runtime supplies an escript program which can unpack these archives and execute them. Building escripts is supported by rebar3.
谢谢，我会用 escript:create/2 来构建它 :clap: :clap: :clap:
在开发环境里用 docker-compose up 启动所有服务时，我的几个容器会输出几百行又几百行内容。有没有方便的办法过滤这些输出，或者更好一些，让这些服务在 docker-compose up 运行时不要写到标准输出？
看来 D 能与 C 链接。我想用 D 编写 Python 扩展模块。我是不是漏掉了什么原因，导致这种方法根本无法运行？
python 可以这样写。 Python.withPackages (q: with q; [ fastapi ]) Micro 编辑器有类似的机制吗？ 能不能把 micro 编辑器的软件包和插件一起指定？:thinking: 那样会方便很多。
