这个报错是什么原因引起的?

正常输入就会有这个错误

I'm having a look but would you have the context from which your code is being called. It is very likely the issue you are facing is in the way you call the code, not the code itself (else other would have faced this issue too).

The error messages seems to indicate that you text has 1 (or 2) character(s) (hence bounds [0, 1]) and that in your code you tried to access position 29.

Also, what version of the library are you using?

我通过继承方式，并重写了

报错是这行代码

I don't think there is an issue with the library, it is more a question for StackOverflow or similar forums as you are having issues debugging your code.

That being said, I'll try to help you still. It's a lot of code which I don't have context for and I'm not even sure is relevant. Best is, if you have located the place of your issue that you either debug your code, or you use the good old method and print some values. What are we looking for? Check the content of your CodeArea (or whatever class you are using from the library) and print it. Also print the imstart and imlength values. You'll discover (as I'm expecting) that your imlength is giving you a value not in match with the content.

As for the root cause, you'll have to investigate to find it out ;-)

I hope that helps

I think you are focusing on the wrong part. You need to find the place in your code that calls this code. What are you doing to trigger the exception? Can you locate the exact line in your code where it happens?

sorry，I've been quite busy lately. I can't let you review the code for the time being.
