ansi.js
|
||
|
|
=========
|
||
|
|
### Advanced ANSI formatting tool for Node.js
|
||
|
|
|
||
|
|
`ansi.js` is a module for Node.js that provides an easy-to-use API for
|
||
|
|
writing ANSI escape codes to `Stream` instances. ANSI escape codes are used to do
|
||
|
|
fancy things in a terminal window, like render text in colors, delete characters,
|
||
|
|
lines, the entire window, or hide and show the cursor, and lots more!
|
||
|
|
|
||
|
|
The code for the example in the screenshot above can be found in the
|
||
|
|
`examples/imgcat` directory.
|
||
|
|
|
||
|
|
#### Features:
|
||
|
|
|
||
|
|
* 256 color support for the terminal!
|
||
|
|
* Make a beep sound from your terminal!
|
||
|
|
* Works with *any* writable `Stream` instance.
|
||
|
|
* Allows you to move the cursor anywhere on the terminal window.
|
||
|
|
* Allows you to delete existing contents from the terminal window.
|
||
|
|
* Allows you to hide and show the cursor.
|
||
|
|
* Converts CSS color codes and RGB values into ANSI escape codes.
|
||
|
|
* Low-level; you are in control of when escape codes are used, it's not abstracted.

|
|
var ansi = require('ansi')
|
||
|
|
, cursor = ansi(process.stdout)
|
||
|
|
|
||
|
|
// You can chain your calls forever:
|
||
|
|
cursor
|
||
|
|
.red() // Set font color to red
|
||
|
|
.bg.grey() // Set background color to grey
|
||
|
|
.write('Hello World!') // Write 'Hello World!' to stdout
|
||
|
|
.bg.reset() // Reset the bgcolor before writing the trailing \n,
|
||
|
|
// to avoid Terminal glitches
|
||
|
|
.write('\n') // And a final \n to wrap things up
|
||
|
|
|
||
|
|
// Rendering modes are persistent:
|
||
|
|
cursor.hex('#660000').bold().underline()
|
||
|
|
|
||
|
|
// You can use the regular logging functions, text will be green
|
||
|
|
console.log('This is blood red, bold text')
|
||
|
|
|
||
|
|
// To reset just the foreground color:
|
||
|
|
cursor.fg.reset()
|
||
|
|
|
||
|
|
console.log('This will still be bold')
