Settings problem with Ruby 1.9 and TheRubyRacer V8.

[falaise]

Hello,

With this little script :

puts " ARGV_0 <#{ARGV.join(", ")}> (#{ARGV.class})"
["foo",2,3,4].each{|p| ARGV.push p}
puts " ARGV_1 <#{ARGV.join(", ")}> (#{ARGV.class})"
begin
puts " $FILENAME <#{$FILENAME}> (#{$FILENAME.class})"
rescue => ex
puts " *** EXCEPTION <#{ex.message}>\n STACK=<#{ex.backtrace.join("\n")}>"
end
puts " ARGV_2 <#{ARGV.join(", ")}> (#{ARGV.class})"

If you start it with Ruby 1.8 you will have :
ARGV_0 <> (Array)
ARGV_1 <foo, 2, 3, 4> (Array)
$FILENAME <-> (String)
ARGV_2 <foo, 2, 3, 4> (Array)
which is right and works with 'bin/envjs rubyracer foo.js' as written in the last line of 'envjs/rubyracer.rb'.

but if you try it with Ruby 1.9 you will have :
ARGV_0 <> (Array)
ARGV_1 <foo, 2, 3, 4> (Array)
*** EXCEPTION <No such file or directory - foo>
STACK=<./this_script.rb:XX:in `

'>
ARGV_2 <2, 3, 4> (Array)
which does not work with 'bin/envjs rubyracer foo.js' as written in the last line of 'envjs/rubyracer.rb'.

I suggest to ignore the global variable '$FILENAME'
Probably you have that problem with all JavaScript engines and Ruby.

Regards.
