klogg

klogg is the fork of glogg - the fast, smart log explorer.

Klogg is cross-platform open source tool designed to view and search information in large log files.

Klogg:

Runs on Unix-like systems, Windows and Mac thanks to Qt5
Supports Perl-compatible regular expressions
Is fast and reads the file directly from disk, without loading it into memory
Utilizes all CPU cores to speed up regex-matching
Detects file encoding using uchardet library (support utf8, utf16, cp1251 and more)
Colorizes the log and search results
Watches for file changes on disk and reloads it (kind of like tail)

How to process 100gb tsv and XML files?
I found this https://klogg.filimonov.dev. - Source: Hacker News / 7 months ago
Lnav Logfile Navigator
Not a CLI tool, but I recently started using https://klogg.filimonov.dev/ klogg (which seems to be a successor of glogg) more and more often. - Source: Hacker News / 9 months ago
Share your greatest free tools
Glogg is a great tool, but unfortunately it is not developed anymore. I maintain a fork -- klogg (https://klogg.filimonov.dev). It is generally faster for both opening a file and performing searches. Current dev builds that use hyperscan regular expression engine can open a file and do a search while glogg would still be indexing that file. Source: almost 3 years ago
Opening large files (>2GB) in Windows
Once I had to go through an unusually large log file which was around 2GB. I am a regular Notepad++ user but it couldn't handle the file. In addition to opening the file I also needed to search around the file for keywords like Error or Exception. I found klogg to be just the right tool for me. It allows for viewing as well searching for words within the large text file easily. - Source: dev.to / almost 3 years ago
pyTermTk, a personal attempt to create a Python TUI
This is still an early stage TUI, many widgets are incomplete or missing (i.e. Text area, partial keyboard support, incomprehensible Documentation) I have very little time to work on it and the progresses are incredibly slow. I develop it in order to create a terminal log viewer that could mimic the features exposed by glogg or klogg. Source: about 3 years ago
