terminal-control v0.0.4

terminal-control

Terminal escape codes made easy. Get in full control.

If your application runs in different environments, don't worry. The init function checks if the process runs in a tty. If it's not, no escape codes will be output even if you call the methods. You can override this behavior by calling init(true).

Installation

Run the following commands to download and install the package:

$ npm install terminal-control

#Usage

var term = require('terminal-control').init().autoClean();

term.setBold(true);
term.moveCursorTo(5,5);
console.log('This text is displayed with an offset!');
