#### Terminal reset Terminal can be cleared with `clc.reset` ```javascript console.log(clc.reset); ``` #### Move around functions ##### clc.move(x, y) Move cursor _x_ columns and _y_ rows away. Values can be positive or negative, e.g.: ```javascript process.stdout.write(clc.move(-2, -2)); // Move cursors two columns and two rows back ``` ##### clc.moveTo(x, y) Absolute move. Sets cursor position at _x_ column and _y_ row ```javascript process.stdout.write(clc.moveTo(0, 0)); // Move cursor to first row and first column in terminal window ``` ##### clc.bol([n[, erase]]) Move cursor to the begining of the line, with _n_ we may specify how many lines away we want to move, value can be positive or negative. Additionally we may decide to clear lines content with _erase_ ```javascript process.stdout.write(clc.bol(-2)); // Move cursor two lines back and place it at begin of the line ``` ##### clc.up(n) Move cursor up _n_ rows ##### clc.down(n) Move cursor down _n_ rows ##### clc.right(n) Move cursor right _n_ columns ##### clc.left(n) Move cursor left _n_ columns #### Terminal characteristics ##### clc.width Returns terminal width ##### clc.height Returns terminal height ### Additional functionalities (provided as separate modules) #### trim(formatedText) _(cli-color/trim)_ Trims ANSI formatted string to plain text ```javascript var ansiTrim = require('cli-color/trim'); var plain = ansiTrim(formatted); ``` #### throbber(write, interval[, format]) _(cli-color/throbber)_ Writes throbber string to _write_ function at given _interval_. Optionally throbber output can be formatted with given _format_ function ```javascript var setupThrobber = require('cli-color/throbber'); var throbber = setupThrobber(function (str) { process.stdout.write(str); }, 200); throbber.start(); // at any time you can stop/start throbber throbber.stop(); ``` ## Tests [![Build Status](https://travis-ci.org/medikoo/cli-color.png)](https://travis-ci.org/medikoo/cli-color) $ npm test
