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.
