An ad-hoc replacement for multitail implemented with tmux and grcat
The following features thus come more or less for free.
- Mouse aware for select, resize etc.
- The full tmux copy-mode for scrollback browsing, searching etc
- Copy scrollback text to the clipboard (y & Y) without any fuzz, via tmux clipboard integration
- Easily extendible by adding bindings for tmux actions. The sky is the limit ..
Color highlighting is done with an node clone of grcat, grcat.js, which is about a factor 10 faster than the python original
Currently a default grcat configuration is baked into tmtail that should be well suited for tailing wildfly logs
Installation
With homebrew or linuxbrew
brew install themadsens/tap/tmtail
From source
Make sure tmux & node is installed, then dump tmtail and grcat.js somewhere in your $PATH
Syntax
Usage: tmtail [-n lines] [{-c colorconf|-h highlightpattern}] <file1> [file2] [file3] ...
Default scrollback is 1000 lines.
A colorconf file is located in the same places grcat will look.
