What is this?

krasota.js is trying to save the world. It provides the ability to carry out the syntactic transformation JavaScript code. Conversions can be both for the protection coding style, and for more complex refactorings logic.

How to use?

Note: For using from command-line you should install it globally -- npm install -g krasota.

$ krasota --help

$ krasota -i tests/split-vars.js -b krasota/lib/beautifiers/split-vars
$ krasota -i tests/join-vars.js -b krasota/lib/beautifiers/trailing-whitespaces -b krasota/lib/beautifiers/join-vars
$ krasota -i my-file.js -o my-beauty-file.js -b ./local/path/to/my/beautifier

See below for available build-in beautifiers.

API

Note: If you are using krasota programatically you should not install it globally, it's enough to declare depends in package.json.

COA

Because of using COA all command-line interface available through require('krasota').COA. Example:

require('krasota').COA
    .invoke({
        input: 'tests/join-vars.js',
        beautifiers: [ 'lib/beautifiers/trailing-whitespaces', 'krasota/lib/beautifiers/join-vars' ]
    })

OMeta

You can use krasota through the require('krasota') in terms of raw OmetaJS-grammas. Take a look to the tests/tests.js for example of usage.

Which beautifiers are available?

There are not many proof-of-concept beautifiers, but it's complex enough for using as samples for your own.

krasota/lib/beautifiers/always-semicolons

Force insert semicolons (you know epic thread). Example:

beforeafter
clearMenus()
!isActive && $parent.toggleClass('open')
clearMenus();
!isActive && $parent.toggleClass('open');

krasota/lib/beautifiers/join-vars

Join multiply consecutive var statements into one var statement with multiply assigns. Example:

beforeafter
var a = 1;
var b = 2;
var c = 3;
var a = 1,
    b = 2,
    c = 3;

krasota/lib/beautifiers/split-vars

Split var statements with multiply assigns into multiply consecutive var statements. Example:

beforeafter
var a = 1,
    b = 2,
    c = 3;
var a = 1;
var b = 2;
var c = 3;

krasota/lib/beautifiers/trailing-whitespaces

Remove trailing whitespaces (it's pretty simple without any examples).
