ansi pansi
Basic ansi formatting, foreground and background colours for use with CLIs.
installation
npm install ansi-pansi
usage
var ansi = require( 'ansi-pansi' ),
foo = ansi( 'foo' );
console.log( foo.bold().blue().background().yellow().toString() );
// logs in bold, blue text on a yellow background => foo
console.log( foo.reset().concat( '\nbar' ).italic().text().white().background().red().toString() );
// logs in bold, blue text on a yellow background => foo
// logs in italic, white text on a red background => bar
ansi.clear(); // same as executing – $> clear – from the command line
API
The following convenience methods are available on the AnsiPansi
instance returned by the ansi
method.
concat( string:String ):this
Concatenated the passed string
to the current String. Any formatting options already set are still valid.
Example:
var ansi = require( 'ansi-pansi' ),
foo = ansi( 'foo' );
foo.red().bold(); // red and bold formatting is applied to 'foo'
foo.concat( 'bar' ); // red and bold formatting is ALSO applied to 'bar'
reset():this
Resets the formatting on the current instance, so any new Strings which are concatenated to it will not have any previous formatting applied.
Example:
var ansi = require( 'ansi-pansi' ),
foo = ansi( 'foo' );
foo.red().bold(); // red and bold formatting is applied to 'foo'
foo.concat( 'bar' ); // red and bold formatting is ALSO applied to 'bar'
foo.reset().concat( 'lorem ipsum' ); // no formatting currently applied to 'lorem ipsum'
toString():ANSIFormattedString
Returns the ANSI formatted String created.
Example:
var ansi = require( 'ansi-pansi' ),
foo = ansi( 'foo' );
foo.red().bold().concat( 'bar' );
foo.concat( 'lorem ipsum' ).italic().blue();
foo.toString(); // returns => '\u001b[0m\u001b[1;31mfoo bar\u001b[0m \u001b[3;34mlorem ipsum\u001b[0m\u001b[m'
API:Formatting
All the options below are methods on the AnsiPansi
instance returned by calling ansi
.
**NOTE: ** Not all formatting across all CLIs.
formatting
bold
, faint
, italic
, underline
, blink
, blinkfast
, invert
, hide
, strike
views
background
, text
NOTE: All colours are automaticallu assigned to text
unless you call background
first. Once a background colour is set, text
is called to allow setting the text colour.
Example:
var ansi = require( 'ansi-pansi' ),
str = ansi( 'lorem ipsum ' ); // string
str.background().red().white() // format above text to be white on a red background
str.concat( ' dolor sit amet' ).red().background().white() // concatenate text and format it with red text on a white background
colours
black
, red
, green
, yellow
, blue
, magenta
, cyan
, white
NOTE: When assigning a colour it will automatically be assigned as the text
colour unless you call background
first.
