index out of bounds: the len is 17526 but the index is 17526 about ratatui HOT 9 CLOSED

This bug is explicitly hit when the zero width character is at the end of the rendering area. Give the fix in #1165 a try (with a patch dependency pointing at the PR) and let me know if that fixes your issue. I'm about 95% certain that will fix the bug you're seeing, but If it doesn't, can you please provide a debug stack trace which includes the relevant line numbers.

Thanks for the bug report. I think the stacktrace will probably be enough to find the error.

Incidentally, have you considered whether it might make sense to add your app's functionality (pinning the first column) to https://github.com/YS-L/csvlens instead of building it out into into another app?

Why doesn't this stacktrace have line numbers?

release mode probably?

Thank you for this hint, I didn't know this tool until now. I tried, but I think there would be more to change then pinning the first column. csvlens breaks csv columns which contain JSON data. This helps reading files, but it is not good for forensic work. Furthermore, I want to highlight lines or columns based on regular expressions. When we do forensic investigation, we often read thousands of log lines per day, to find things that should not be there. I want the tool to support this work.

However, I will include csvlens in my future work, because until now I used xsv table | less -S; while csvlens looks much better. 👍

Both of these seem like reasonable features to implement in csvlens (not breaking json data and highlighting lines or columns)

You're right. Let me think about this

Also, pinning the first n columns would also make a good feature there too. I don't want to discourage you from writing an app like this if you want to, but given a choice of 1 excellent app or 2 good ones, I'd generally take the first choice.

Fixed by #1165

Thanks a lot for your work 👍
