LogRust

A log file viewer written in Rust using iced-rs

Currently, unusable. It only counts occurrences of specific log levels and displays them in a UI. Nevertheless, it does so in an extremely fast manner (on my machine, it takes around 15 seconds to scan a ~4.5 Gb file with ~23.5 million lines)

As the name implies, this is pretty much a toy project. I always wanted to get into Rust while also trying some kind of UI framework. And I happened to need some library that could open and filter large logs by their log level so here we are

logrust's Issues

Scrollview for the actual log file content

Displaying the actual content is probably the hardest task. There's quite a few things to be aware of:

• For performance concerns, we should only load about 2 or 3 times the window height of lines. This allows the user to scroll a bit while we dynamically load more data
• When changing filter criteria the scroll state should probably be reset since the scroll state might have changed

Theming

We need a dark mode at least. Maybe add some other options to choose from

Filter options

How to display those in the most efficient way? In the top bar or in a split panel to the left/right of the log? Ideally, we have a few options to filter logs

• By log level (clarify if user defined or opinionated)
• By timestamp (probably need to have some date format setting for this)
• By search string

Grouping messages

Also a few options for this one:

• Group by log level
• Group by message
• Group by timestamp (this might be useful when comparing logs, i.e. for recurring jobs)

Tab/Title bar

There needs to be some form of tab bar at the top where people can change all kinds of settings, choose a file, view an about page, etc.

iced-aw has a widget for this iirc
