Question

这可能很简单。例如，这个sys.config进入mix config.exs：

{gsms, [{interfaces,
  [
   {gsms_0705, 1, [{device,"/dev/tty.usbserial-FTF5DP2J"},
           {bnumber, "<phone-number>"},{baud,19200},
           {reopen_timeout, 5000}]}
   {gsms_0705, 2, [{device,"/dev/tty.HUAWEIMobile-Pcui"},
           {bnumber, "<phone-number>"},
           {reopen_timeout, 5000}]}
   {gsms_0705, 3, [{device, "/dev/tty.usbserial"},
          {bnumber, "<phone-number>"},
          {baud, 9600}]}
  ]}
]}

Answer 1

如果您修复语法错误（缺少逗号）并添加强制性尾随点，您甚至可以从Elixir解析Erlang术语并让解析器为您进行转换：

erlang_term = '{gsms, [{interfaces, [
  {gsms_0705, 1, [{device,"/dev/tty.usbserial-FTF5DP2J"},
                  {bnumber, "<phone-number>"},{baud,19200},
                  {reopen_timeout, 5000}]},
  {gsms_0705, 2, [{device,"/dev/tty.HUAWEIMobile-Pcui"},
                  {bnumber, "<phone-number>"},
                  {reopen_timeout, 5000}]},
  {gsms_0705, 3, [{device, "/dev/tty.usbserial"},
                  {bnumber, "<phone-number>"},
                  {baud, 9600}]}
 ]}
]}.'

{:ok, tokens, _} = :erl_scan.string(erlang_term)
{:ok, result} = :erl_parse.parse_term(tokens)
IO.inspect result, limit: :infinity

打印：

{:gsms,
 [interfaces: [{:gsms_0705, 1,
    [device: '/dev/tty.usbserial-FTF5DP2J', bnumber: '<phone-number>',
     baud: 19200, reopen_timeout: 5000]},
   {:gsms_0705, 2,
    [device: '/dev/tty.HUAWEIMobile-Pcui', bnumber: '<phone-number>',
     reopen_timeout: 5000]},
   {:gsms_0705, 3,
    [device: '/dev/tty.usbserial', bnumber: '<phone-number>', baud: 9600]}]]}

元组的第一部分是应用程序名称:gsms，元组的另一部分是包含实际选项的proplist。您可以放下周围的括号并稍微重新格式化，然后您将获得：

config :gsms, interfaces: [
  {:gsms_0705, 1, [
    device: '/dev/tty.usbserial-FTF5DP2J',
    bnumber: '<phone-number>',
    baud: 19200,
    reopen_timeout: 5000]},
  {:gsms_0705, 2, [
    device: '/dev/tty.HUAWEIMobile-Pcui',
    bnumber: '<phone-number>',
    reopen_timeout: 5000]},
  {:gsms_0705, 3, [
    device: '/dev/tty.usbserial',
    bnumber: '<phone-number>',
    baud: 9600]}]

Answer 2

我想这就是它：

config :gsms, :interfaces, [
  {:gsms_0705, 1, [device: '/dev/tty.usbserial-FTF5DP2J',
                   bnumber: '<phone-number>',
                   baud: 19200,
                   reopen_timeout: 5000]},
  # and so on
]

:gsms是您要配置的应用，:interfaces是您通过Application.get_env/2（Application.get_env(:gsms, :interfaces)）和{:gsms_*, ...}列表检索的密钥} tuples是该键的值。

如何将Erlang sys.config转换为Elixir config.exs？
