An ad-hoc replacement for [multitail](https://vanheusden.com/multitail/) 
implemented with [tmux](https://github.com/tmux/tmux) and [grcat](https://github.com/garabik/grc)

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](https://www.wildfly.org/) logs

## Installation
#### With homebrew or linuxbrew
```brew install themadsens/tap/tmtail```
#### From source
Make sure tmux & node is installed, then dump [tmtail](tmtail) and [grcat.js](grcat.js) somewhere in your $PATH

## Syntax
`Usage: tmtail [-n lines] [{-c colorconf|-h highlightpattern}] <file1> [file2] [file3] ...`

Default scrollback is 1000 lines.<br/>
A `colorconf` file is located in the same places [grcat](https://github.com/garabik/grc#configuration) will look.
