LESS to Stylus converter

Convert LESS to Stylus by parsing LESS sources and traversing resulting AST.

Installation

% npm install -g less2stylus

% less2stylus styles.less > styles.styl

Bootstrap 3.0 can be translated as-is.

every mixin with no params or all params having default values will have corresponding class generated, so
```
.some-mixin() {
  ...
}
```
results in
```
some-mixin()
  ...

.some-mixin
  some-mixin()
```
call to a mixin with no params will result in an @extend of corresponding class, so
```
body {
  .some-mixin()
}
```
results in
```
body
  @extend .some-mixin
```
@media directives which use variables to specify a condition on which rules apply will translate into an additional variable declaration which holds @media condition. This is because of Stylus limitation not to allow variables inside @media conditions.
```
@media screen and (min-width: tablet) {
  ...
}
```
results in
```
var213123edf25df1a = "screen and (min-width: " + tablet + ")"
@media var213123edf25df1a
  ...
```
if there are mixins which named translate, translate3d, scale, skew, rotate then they will be prefixed with mixin- in resulted Stylus sources. This is to prevent recursive mixin invokations.
