New Hash synthax of Ruby not supported by synthax checking

Reported by Vidmantas | January 6th, 2011 @ 10:10 AM

Synthax checker of ruby doesn't recognise new Hash synthax available from Ruby 1.9. For example:

h = { a: 1, b: 2 } # <= shows as synthax error but works perfectly fine in Ruby 1.9.x

This is due to the fact that JRuby is run in 1.8 mode, an we use the same process for syntax checking that is running Redcar. It should be easily fixable if we run Redcar in 1.9 mode. I'll see if that breaks anything else.

Well, we should be able to just specify to the embedded JRuby parser to use 1.9 mode, we shouldn't need to run the whole editor in it. We can make it configurable in the Syntax Checker menu whether it should use 1.8 or 1.9 mode.

We should move to 1.9 mode in Redcar anyway though.

Just tried it, seems that JRuby 1.5.3 doesn't support the new Hash syntax, yet. 1.6 will be the first to ship with official 1.9 support and is due to be released soon, I think we should post-pone until then.

JRuby 1.6.x has been out a while, is this enhancement still planned? With rails 3.1 using the new syntax it's now a little more useful.

Wants happening with this. Are there still technical difficulties in implementing syntax checking compatible for 1.9? For an editor built in ruby for ruby, you'd think this would be top priority.

Still no progress I assume. This is getting hard to live with. I love redcar, but it's a shame such a fundamental feature is broken, and has been so for a year.
