How to check ruby syntax error in ruby code

ruby

Solution

Under MRI, you can use `RubyVM::InstructionSequence#compile` (relevant documentation) to compile Ruby code (which will throw exceptions if there are errors):

2.1.0 :001 > RubyVM::InstructionSequence.compile "a = 1 + 2"
 => <RubyVM::InstructionSequence:<compiled>@<compiled>>

2.1.0 :002 > RubyVM::InstructionSequence.compile "a = 1 + "
<compiled>:1: syntax error, unexpected end-of-input
a = 1 +
        ^
SyntaxError: compile error
        from (irb):2:in `compile'
        from (irb):2
        from /usr/local/rvm/rubies/ruby-2.1.0/bin/irb:11:in `<main>'

Problem

I use following now to check syntax error: ``` system "ruby -wc path/to/file.rb" ``` but it very waste time if there are too many file(for instance, i refactory code), so my question is: is there way to ruby syntax check in ruby code?
