Successfully recompiling a module:

08:34:43.255 [info] /Code/Webmachine/src/webmachine_dispatcher.erl:0: Recompiled.
08:34:43.265 [info] webmachine_dispatcher: Reloaded! (Beam changed.)

Warnings:

08:35:06.660 [info] /Code/Webmachine/src/webmachine_dispatcher.erl:33: Warning: function dispatch/3 is unused

Errors:

08:35:16.881 [info] /Code/Webmachine/src/webmachine_dispatcher.erl:196: Error: function reconstitute/1 undefined
/Code/Webmachine/src/webmachine_dispatcher.erl:250: Error: syntax error before: reconstitute

Stopping and Pausing:

sync:stop().
sync:pause().

指定要sync的目录:

[
    {sync, [
        {src_dirs, {strategy(), [src_dir_descr()]}}
    ]}
].

-type strategy() :: add | replace.
  add:增加指定目录
  replace:只sync指定目录
-type src_dir_descr() :: { Dir :: file:filename(), [Options :: compile_option()]}.
实例:
[
    {sync, [
        {src_dirs, {replace, [{"./priv/plugins", [{outdir,"./priv/plugins_bin"}]}]}}
    ]}
].

指定日志等级:

all: Print all console notifications
none: Print no console notifications
[success | warnings | errors]: A list of any combination of the atoms success, warnings, or errors. Example: [warnings, errors] will only show warnings and errors, but suppress success messages.
true: An alias to all, kept for backwards compatibility
false: An alias to none, kept for backwards compatibility
skip_success: An alias to [errors, warnings], kept for backwards compatibility.

1.Loaded from a .config file
{log, all},
{log, [success, warnings]},
2. As an environment variable called from the erlang command line:
erl -sync log all
erl -sync log none
3. From within the Erlang shell:
sync:log(all);
sync:log(none);
sync:log([errors, warnings]);

配置实例:

[
  {sync, [
    {growl, all},
    {log, all},
    {non_descendants, fix},
    {executable, auto},
    {whitelisted_modules, []},
    {excluded_modules, []}
  ]}
].
