Ruby

This is related to #13813.

In lib/uri/ftp.rb, documentation for #path below:

 # Returns the path from an FTP URI. # # RFC 1738 specifically states that the path for an FTP URI does not # include the / which separates the URI path from the URI host. Example: # # ftp://ftp.example.com/pub/ruby # # The above URI indicates that the client should connect to # ftp.example.com then cd pub/ruby from the initial login directory. # # If you want to cd to an absolute directory, you must include an # escaped / (%2F) in the path. Example: # # ftp://ftp.example.com/%2Fpub/ruby # # This method will then return "/pub/ruby" # 

The URIs what are started with "ftp://" is indented,
and indented documentation is treated as Ruby code.
So this becomes strange documentation, it's highlighted as some Ruby tokens.

The screenshot below is rendered HTML of URI::FTP documentation on ruby-doc.org:
http://ruby-doc.org/stdlib-2.4.1/libdoc/uri/rdoc/URI/FTP.html

The second URI of FTP isn't highlighted,
because when a string is invalid as Ruby tokens in RDoc lexical analyser,
it's treated as plain text.

I think this should be fixed to correct documentation.
The patch what I attached on this issue fixes it like below:

 # Returns the path from an FTP URI. # # RFC 1738 specifically states that the path for an FTP URI does not # include the / which separates the URI path from the URI host. Example: # # +ftp://ftp.example.com/pub/ruby+ # # The above URI indicates that the client should connect to # ftp.example.com then cd pub/ruby from the initial login directory. # # If you want to cd to an absolute directory, you must include an # escaped / (%2F) in the path. Example: # # +ftp://ftp.example.com/%2Fpub/ruby+ # # This method will then return "/pub/ruby" #
