API

build(input, [options,] callback)

input

Required
Type: string

Input less content.

options

rtl

Type: boolean
Default: true

Create mirrored css for right-to-left support.

rootPaths

Type: array of string

Root paths to use for import directives.

This option differs from the less compiler.paths option.
It is useful if less files are located in separate folders but referenced as they would all be in one.
If rootPaths are provided and a file can not be found, the compiler.paths option will be used instead.

Note: parser.filename has to be set to the path of the input file in order to get this working.

Example

rootPaths: [ './lib1', './lib2' ]

Folder structure

lib1
 my
  themes
   foo
    foo.less
lib2
 my
  themes
   bar
    bar.less

lib2/my/themes/bar/bar.less

@import "../foo/foo.less"; /* lib1/my/themes/foo/foo.less will be imported */

parser

Type: object

Options for the less parser (less.Parser).

compiler

Type object

Options for the less compiler (tree.toCss).

Type: function

result.css

Type: string

Mirrored css for right-to-left support (if rtl option was enabled).
