colorize-text.js

//colorize-text.js -by- KenDB3 of KD3net (http://bbs.kd3.us)
//This script is meant for use with Synchronet BBSes.
//It requires JSexec.exe (from SBBS) to be run from command line.
//It was written in the spirit of the 1991 program A2A - ASCII to ANSI file converter by David Kauffman A.K.A. Ansi.
//colorize-text.js takes a plain text file and adds Synchronet Ctrl-A colorization.
//If you prefer ANSI color encoding, you could convert the output file with the SBBS utility asc2ans.exe.

//Usage: 
//Pick a color and intensity for Text, a color and intensity for Numbers, and a color and intensity for Non-Text Characters
//Add the colorize-text.js script to your mods (/sbbs/mods/) or your exec (/sbbs/exec/) directory.
//Command Line: (be sure you are in the correct directory to call jsexec.exe, ie /sbbs/exec/)
//jsexec.exe colorize-text.js input-plain-text output-ctrl-a-ascii color1 H/L color2 H/L color3 H/L
//---All options are required---
//Input & Output files
//		input-plain-text should be a plain text file with no ANSI or any other color codes (ctrl-a, pipe, wildcat, etc...)
//		output-ctrl-a-ascii will be a Control-A encoded ASCII file (Synchronet Color Codes)
//Colors are one letter and can be any of the following: 
//		Red=R, Green=G, Yellow=Y, Blue=B, Magenta=M, Cyan=C, White=W
//		color1 is for TEXT: A-Z, a-z
//		color2 is for Numbers: 0-9
//		color3 is for Non-Text Characters: .,:;-() etc...
//H/L is for High or Low Intensity ANSI Colors
//		This should also be one letter for each of the 3
//		H - High Intensity (Bright) Color
//		L - Low Intensity (Dull) Color
//Example Command Line - Low Intensity Cyan Text, High Intensity Cyan Numbers, High Intensity Blue Non-Text
//		jsexec.exe colorize-text.js C:\sbbs\text\riweathr.msg C:\sbbs\text\riweathr.asc C L C H B H
//See this in use on my BBS here:
//		http://bbs.kd3.us/weather/weather.ssjs

//DISCLAIMER: This script is just meant to add Ctrl-A encoding. I wrote it to be used with JSexec.exe, 
//but, it could possibly be used by other JS scripts. I do not expect it to mangle any of your text, but
//if it does, I do not take any responsibility. PLEASE have a backup copy of your file BEFORE using this
//script, just in case. 

//Big thanks to digital man, I did not know half of this stuff was possible until I saw his JS script
//called sbbsecho_upgrade.js (http://cvs.synchro.net/cgi-bin/viewcvs.cgi/exec/sbbsecho_upgrade.js?view=log).
//It showed me the basics I needed to make this script do what it does.
