Description

lazyjournal -version reports "0.8.5"; it runs in a docker container. The container's OS is Rocky Linux 8, the host is MacOS.

After starting lazyjournal -mouse-disable I was watching the logs of a systemd unit. In the field "Filter (Default)" I had entered a string which was highlighted in "Logs" below.

While scrolling up and down through the filtered logs with the mouse, the program suddenly closed and I saw the following message in the terminal

configuration file not found
panic: runtime error: index out of range [310] with length 7

I was scrolling up and down repeatedly, looking for something.

[vasgard-bronsen]

I can replicate the behavior ((rapid) scrolling causes panic), this time with slightly different numbers.

I'll try to reproduce this in my environment and give you feedback.

@vasgard-bronsen I didn't understand what system you ended up using? The original Debian-based image.

[vasgard-bronsen]

lazyjournal runs inside a docker container. The container uses Rocky Linux 8 as OS; which is basically RedHat Enterprise Linux with a different name. The architecture is arm64.

[Lifailon]

I've made some fixes that should help fix the errors.

@vasgard-bronsen can you install the app using go install github.com/Lifailon/lazyjournal@latest or build it from source (for this you can use make build install) to check it?

Fixes included in release 0.8.6.
