Can add one more rule which judging by user provided pattern

[addozhang]

Provide a pattern parameter, such as time pattern.

If match, flush buffer and add current record to buffer. If not add current record to buffer only without flush.

Because it is not friendly if starts with message contains Exception|Error|Throwable|V8 errors stack trace

[igorpeshansky]

I'm not sure I understand what you're proposing here. Can you provide a specific example of an actual stack trace that isn't supported today?

[addozhang]

@igorpeshansky As below, what I want is the stacktrace combined with previous one line as single line.

In curent detect exception implementation, the first line of java stacktrace starting with one of Exception|Error|Throwable|V8 errors stack trace. Traditionally, some developers hope the stacktrace

I made simple change to get this. Later I will commit the change. But I am not Ruby developer, so it is better for some others can implement it.
