My use case is a Java error that has a long stack trace that I'd want to see.

egrep has this feature.

-A NUM, --after-context=NUM
Print NUM linesof trailing context after matchinglines.
Places a line containing -- betweencontiguous groups of
matches.

-B NUM, --before-context=NUM
Print NUM lines of leading context before matching lines.
Places a line containing -- betweencontiguous groups of
matches. ]]> https://www.logfusion.ca/Discussions/View/hightlight-rule-to-show-current-line-and-previous-or-next-lines/?ID=77de919f-7f1d-48fd-8282-0d6ff4027685#2 Mon, 03 Mar 2014 19:42:31 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/hightlight-rule-to-show-current-line-and-previous-or-next-lines/?ID=77de919f-7f1d-48fd-8282-0d6ff4027685#2 LogFusion I like this idea a lot

I've added it to our list, and if we're able to implement it in a future version, we'll be sure to let you know!

As a workaround, what I currently do is select the highlighted line, then show all lines to look at the ones around it. It's a bit manual, but does the trick.

Thanks! ]]> https://www.logfusion.ca/Discussions/View/hightlight-rule-to-show-current-line-and-previous-or-next-lines/?ID=77de919f-7f1d-48fd-8282-0d6ff4027685 Mon, 03 Mar 2014 15:32:44 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/hightlight-rule-to-show-current-line-and-previous-or-next-lines/?ID=77de919f-7f1d-48fd-8282-0d6ff4027685 LogFusion Hello;

Would it be possible to show a number of lines around a highlighted line?

A log file can contain errors and the statement causing the error would be a few lines above the error. For example.

Would it be possible to show a few lines before the actual error message? For example an additional configuration parameter in the highlight rule dialog: lines shown before or after the highlighted line.

Kind regards;
