Hi, thanks for the great job.
I tried your online beautifier against this code

eval(function(p,a,c,k,e,d){while(c--)if(k[c])p=p.replace(new RegExp('\\b'+c.toString(a)+'\\b','g'),k[c]);return p}('a 3c="3b.3a.39.38.37";36("2://4.d.5/19-p-35.34");6(g.3==3&&g.3.33.32(\'19\')!=-1){9.3=\'2://4.d.5/p\'}31{8("30").2z({o:"2://15.7.14.13:12/11/v.10",z:"2",18:"2://4.d.5/18/2y.2x",2w:{o:\'2://4.d.5/2v/2u.2t\',2s:\'2://4.d.5/p\'},2r:"2q.2p",2o:"2://4.d.5",2n:"17",2m:1,2l:"2k",2j:"2i",2h:2g,2f:2e,2d:[{f:"17",s:"9.3 = \'<16 2c>/<16 2b>\';/2a/29.28"},{f:"27",26:{o:\'2://15.7.14.13:12/11/v.10\',\'z\':\'2\'}},{f:"25"}]});a j;a i=0;a n=0;a c=0;h=(y.3!=y.24.3)?9.23:9.3;8().22(b(x){6(c>0)n+=x.w-c;c=x.w;6(0!=0&&n>=0){c=-1;8().21();8().20(1z);$(\'#1y\').m();$(\'l.k\').m()}});8().1x(b(x){c=-1});8().1w(b(x){u(x);t()});8().1v(b(){$(\'l.k\').m()});b u(x){$(\'l.k\').1u();6(j)1t;j=1;}b t(){6(i==0){a e=9.1s("1r");e.f="1q/1p";e.s=\'2://4.1o.1n/1m/1l.1k?1j=1i\';9.1h.1g(e);i=1}}6(h.r(\'1f-1e.q\')!=-1){1d(1c)}6(h.r(\'1b.5\')!=-1){g.3=\'2://4.1a.q/\'}}',36,121,'||http|location|www|tv|if||jwplayer|document|var|function|p0151296|rapidvideo|js|type|top|ref_url|first_play|vvplay|video_ad|div|show|tt151296|file|24o0gquf1f4j|net|search|src|show_on_play|doPlay||position||window|provider|mp4|5rzifi5s4wamkzh6rgwcwvdm4qkfklw42cfianycqgwefhf3vvfvkzrnettq|8777|210|161|50|TMPL_VAR|flash|skin|embed|guardaserie|serietv|true|CloseWindows|01|cineblog|appendChild|body|187036|zone|php|display|ad|com|yieldtraffic|javascript|text|script|createElement|return|hide|onComplete|onPlay|onSeek|play_limit_box|false|setFullscreen|stop|onTime|referrer|parent|download|config|html5|swf|player|video_player|file_code|site_url|modes|370|height|896|width|start|startparam|1363|duration|bufferlength|primary|aboutlink|Tv|RapidVideo|abouttext|link|png|video_logo|images|logo|xml|five|setup|jwplayer2|else|indexOf|href|html|896x370|jw_player_fix|avi|ita|hardsub|s01e08|Yonderland|tv_file_name'.split('|')))

and it correctly beautify it. Then I have installed your python library and tested against the same js but this result in an error:

>>> res = jsbeautifier.beautify_file('beautify.js')

AttributeError: 'NoneType' object has no attribute 'groups'

Is there any way to solve this problem?
Thanks in advance
