Lews

Little Lews compiles all your Less files and and keeps track of their @imports

Why you need it

You, Lenny, have these Less files with the following imports:

bundle.less
\_ fonts.less
|  \_ icons.less
|_ buttons.less
|  \_ helpers.less
|_ helpers.less

Say you edit helpers.less, Lews will compile helpers.less, buttons.less and bundle.less. Should you edit icons.less, Lews will compile icons.less, fonts.less and bundle.less.

Pretty neat, right?

Features

• Compiles all Less files that imports the changed Less file recursively
• Gulp-support
• Experimental socket-support - compiles filename sent through a socket. This is useful when working over NFS.

Usage examples

Cli:

Usage: lews [options] sourcePath [destPath]
    --no-source-map: dont inline source maps
    --use-socket [socketPath]: listen on socket for files to compile
    --no-watch: don't watch for file changes
    --watch-interval interval: specify watch interval
    --help / --usage: this help message

Gulp:

var gulp = require('gulp'),
    Lews = require('lews');

gulp.task('dev', function() {
    var lews = new Lews('css', 'public/css');
    gulp.watch(['css/**/*.less'], lews.gulpWatchCb.bind(lews));
});

With sockets and Vim: (useful then working over NFS)

lews --use-socket /srv/www/testsite/lews.sock --watch-interval 3000 /srv/www/testsite/css /srv/www/testsite/public/css

autocmd BufWritePost /srv/www/testsite/css/*.less silent !echo -ne '<afile>:p' | nc -U /srv/www/testsite/lews.sock
