通过 rebar shell 将 args 传递给 erl？

Question

我正在使用 "rebar shell" 来测试我的应用程序。这记录为：

Start a shell with project and deps preloaded similar to
'erl -pa ebin -pa deps/*/ebin'.

如何向 'erl' 的底层调用添加额外的参数？为了例如，我想添加特定于应用程序的环境变量和运行一个Module/Function。我想调用类似的东西：

 erl -pa ebin -pa deps/*/ebin -browser_spy browser_exe "/my/dir" -run bs_example test

（我希望 code:priv_dir 像使用钢筋 shell 时那样工作，上面的 'erl' 命令不执行此操作）。

Answer 1

你不能

rebar shell 实际上不执行 erl ... 命令，而只是试图 复制其行为.

实际上，通过添加 code:add_pathz

路径，钢筋只是将自己变成 shell 并模仿 -pa

有关实施细节，请参阅 here：

shell(_Config, _AppFile) ->
    true = code:add_pathz(rebar_utils:ebin_dir()),
    %% scan all processes for any with references to the old user and save them to
    %% update later
    NeedsUpdate = [Pid || Pid <- erlang:processes(),
        proplists:get_value(group_leader, erlang:process_info(Pid)) == whereis(user)
    ],
    %% terminate the current user
    ok = supervisor:terminate_child(kernel_sup, user),
    %% start a new shell (this also starts a new user under the correct group)
    _ = user_drv:start(),
    %% wait until user_drv and user have been registered (max 3 seconds)
    ok = wait_until_user_started(3000),
    %% set any process that had a reference to the old user's group leader to the
    %% new user process
    _ = [erlang:group_leader(whereis(user), Pid) || Pid <- NeedsUpdate],
    %% enable error_logger's tty output
    ok = error_logger:swap_handler(tty),
    %% disable the simple error_logger (which may have been added multiple
    %% times). removes at most the error_logger added by init and the
    %% error_logger added by the tty handler
    ok = remove_error_handler(3),
    %% this call never returns (until user quits shell)
    timer:sleep(infinity).

通过 rebar shell 将 args 传递给 erl？

Pass args through rebar shell to erl?

erlang

rebar

erl
