zaje is a syntax highlighter that aims to cover all your shell colouring needs. With a spot of one-line shell functions, it can act as an ad-hoc replacement for both cat and tail.

Features

Supports over a 100 lexers for programming languages, configuration and log formats and UNIX commands (this is done using the highlight Go package
Can accept input as an argument as well as from an STDIN stream
Can detect the lexer to use based on:
- The file name (when acting in cat mode)
- The first line of text (so it will usually work nicely when piping as well)
Supports explicit specification of the lexer to use via a command-line arg and an ENV var
Easily to deploy: since it’s a Go CLI app, it’s one, statically linked executable with no dynamic deps
Easily extendable: see Revising and adding new lexers for details

Installation

$ curl https://raw.githubusercontent.com/jessp01/zaje/master/install_zaje.sh > install_zaje.sh
$ ./install_zaje.sh
