Bug #6488: String#slice example has a syntax error

• Status: Closed

http://www.ruby-doc.org/core-1.9.3/String.html#method-i-slice has a syntax error:

a[%raeiou\11//] #=> "ell"
a[%raeiou\11//, 0] #=> "ell"
a[%raeiou\11//, 1] #=> "l"
a[%raeiou\11//, 2] #=> nil

Oh, I have just realized that similar problems exist in the other regexp examples on the page, not just for slice.

Seems this is a renderer issue. Eric, what do you think?

I was unable to reproduce this with ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux] and rdoc 3.9.4

Could be an issue with ruby-doc.org?

This is a bug in RDoc's ruby parser

Fixed by eaf2b80c and 0d72fc0d to the rdoc repository.

The references to the RDoc github commits don't show up as live links, so to save others the trouble of finding them, here are URLs for each:

More specifically, it was a problem in the HTML pages generated by RDoc v3.12 (and ruby-doc.org was indeed using that version).

Over the weekend James Britt regenerated the "core" and "std=lib" RDoc pages (for all Ruby versions) using a copy of rdoc that included this bug's ruby_lex.rb patches, so the regexp literals on those pages should be fixed now.

(The gem RDocs on the site are built separately and so they may not have been updated yet.)
