Lex-highlighter 100% stream-based $\mathcal O(n)$ syntax highlighter for ANSI terminal Warning This is proof-of-concept implementation and WON't be colorful like existing syntax highlighter solutions. Stream format <stream> ::= (< span > < newline >) * <span> ::= < number > < ws > < number > < ws > < colorprofile > <number> ::= 0 | [1 - 9] [0 - 9] * <colorprofile> ::= < color > | " ! " < color > | < color > < ws > " ! " < color > | " ! " < color > < ws > < color > <color> ::= " # " < hex >{6} <hex> ::= [0 - 9a - fA - F] <ws> = ( " " | " \t " ) + Negative indexing is not supported. Currently only hex colors are supported. Hex colors should have exactly 6 digits. Use ! (inverse) to represent background color. You can use foreground and background colors at the same time, but you can't use more than one foreground / background colors. Styles( italic , bold , etc) are not supported yet. Empty lines are not allowed.
