rkelly gem выдал исключение для меня, поэтому я использовал вилку rkelly-remix - вы должны удалить оригинал, потому что они используют одно и то же имя:
gem uninstall rkelly
gem install rkelly-remix
У меня был следующий код JS:
var xpos = 0;
var ypos = 0;
var city = 'Parish';
var cashSaldo = '0.00';
var bankSaldo = '';
var address = 'Lot: 0 - 0';
var simplemode = true;
var email_reminder = true;
var text_citylist = 'Take a cab to';
var text_nostreet = 'Lot';
var text_lotpos = 'Lot:';
var text_products_title = 'Products';
var text_products_subtitle = 'Produce and set prices';
var text_title = 'Miniconomy';
var text_has_harbor = 'This city has a harbor';
var products = {"gron":{"ln":"Clay"},"stee":{"ln":"Brick"},"ijee":{"ln":"Iron Ore"},"boom":{"ln":"Tree"},"goud":{"ln":"Gold"},"olie":{"ln":"Oil"},"oven":{"ln":"Oven"},"ijze":{"ln":"Iron"},"hout":{"ln":"Wood"},"schi":{"ln":"Bulletproof Vest"},"benz":{"ln":"Gas"},"pomp":{"ln":"Pump"},"schr":{"ln":"Screwdriver"},"sche":{"ln":"Shovel"},"moto":{"ln":"Electrical Engine"},"plas":{"ln":"Plastic"},"zaag":{"ln":"Saw"},"mach":{"ln":"Machine"},"chip":{"ln":"Chip"},"tele":{"ln":"Telephone"},"came":{"ln":"Camera"},"alar":{"ln":"Alarm"},"glas":{"ln":"Glass"}};
var isChristmas = 0;
var newMap = 1;
И этот код мне пришлось написать, чтобы разобрать его:
o = lambda do |x|
next true if x == [:true]
next x.size != 2 ? fail : eval(x[1].to_s) if x[0] == :lit || x[0] == :str
next x.size != 2 ? fail : Hash[ x[1].map do |a,b,c|
fail unless a == :property
fail unless b.is_a? Symbol
[eval(b.to_s).to_sym, o[c]]
end ] if x.first == :object
fail x.inspect
end
require "rkelly"
result = Hash[ RKelly::Parser.new.parse(my_js_code).to_sexp.map do |k, v|
fail unless k == :var
fail unless v.size == 1
a, b, c = v.first
fail unless a == :var_decl
k, v = c
fail unless k == :assign
[b, o[v]]
end ]
В результате:
