+`is_enable`决定调试功能是否开启。
+若为`true`，那么会在替换字符串时向日志中输出一行调试信息，调试信息的格式由`output_format`决定，调试信息的内容由`output_mode`决定。
+若为`false`，则不会在替换字符串时向日志中输出任何内容。

+`output_format`决定了调试信息的格式，默认为`<source> -> <target>`。
+`<source>`为源内容，即未做替换前的字符串；`<target>`为做替换后的字符串。
+还有一个`<stack>`未展示出来，因为输出的很多，容易污染日志。
+`<stack>`为堆栈跟踪数组，是此字符串所在类的`StackTrace`(包括本mod)，它更多是为`target_class`中的`stack_depth`和`name`服务的。

+`is_enable` determines whether the debugging feature is enabled.
+If it is `true`, a line of debugging information will be output to the log when replacing the string,
+The format of debugging information is `output_format`, and determines the content of debugging information by `output_format`.
+If it is `false`, Will not output anything to the log when replacing the string.
 
-See for [Section-Modular](#Modular)
+`output_format` determines the format of debugging information. The default is `<source> -> <target>`.
+`<source>` is the source string, that is, the string before replacement. and `<target>`is the replacement string.
+There is another `<stack>` that is not shown, if you include it in `output_format`,
+the log will be polluted because of the large amount of output information.
+`<stack>` is a stacktrace array, which is the `StackTrace` (including this mod) of the class of this string,
+This value is more for `stack_depth` and `name` in `target_class`.
 
-The format of the config file is roughly as follows:
