# Terminal Kit

A full-blown terminal lib featuring: 256 colors, styles, keys & mouse handling, input field, progress bars, 
screen buffer (including **32-bit composition** and **image loading**), text buffer, and many more...

Whether you just need colors & styles, build a simple interactive command line tool or a complexe terminal application:
this is the absolute terminal lib for Node.js!

It does **NOT** depend on ncurses.

Some tutorials are available at [blog.soulserv.net/tag/terminal](http://blog.soulserv.net/tag/terminal/).



## Screenshot, PleaZe!

This is a fraction of what Terminal-Kit can do, with only few lines of code.

## Quick examples

Some examples (note that if you execute all at once, some examples overwrite each other) :

```js
// Require the lib, get a working terminal
var term = require( 'terminal-kit' ).terminal ;

// The term() function simply output a string to stdout, using current style
// output "Hello world!" in default terminal's colors
term( 'Hello world!\n' ) ;

// This output 'red' in red
term.red( 'red' ) ;

// This output 'bold' in bold
term.bold( 'bold' ) ;

// output 'mixed' using bold, underlined & red, exposing the style-mixing syntax
term.bold.underline.red( 'mixed' ) ;

// printf() style formatting everywhere:
// this will output 'My name is Jack, I'm 32.' in green
term.green( "My name is %s, I'm %d.\n" , 'Jack' , 32 ) ;

// Since v0.16.x, style markup are supported as a shorthand.
// Those two lines produce the same result.
term( "My name is " ).red( "Jack" )( " and I'm " ).green( "32\n" ) ;
term( "My name is ^rJack^ and I'm ^g32\n" ) ;

// Width and height of the terminal
term( 'The terminal size is %dx%d' , term.width , term.height ) ;

// Move the cursor at the upper-left corner
term.moveTo( 1 , 1 ) ;

// We can always pass additional arguments that will be displayed...
term.moveTo( 1 , 1 , 'Upper-left corner' ) ;

// ... and formated
term.moveTo( 1 , 1 , "My name is %s, I'm %d.\n" , 'Jack' , 32 ) ;

// ... or even combined with other styles
term.moveTo.cyan( 1 , 1 , "My name is %s, I'm %d.\n" , 'Jack' , 32  ) ;

// Get some user input
term.magenta( "Enter your name: " ) ;
var input = await term.inputField().promise ;
term.green( "\nYour name is '%s'\n" , input ) ;

// Cleanly exit : avoid having junk escape characters and restore default style.
// Any interactive functions (like .inputFiled(), .yesOrNo(), etc) will open "stdin" and listen for events,
// so the process will NOT exit except explicitly (or explicitly calling .grabInput( false )).
term.processExit() ;
```
