Ruby

Feature #11537

Updated by nobu (Nobuyoshi Nakada) almost 10 years ago

I sometimes somtimes write following code with rails application: 

 ```ruby ```rb 
 u = User.find(id) 
 if u && u.profile && u.profile.thumbnails && u.profiles.thumbnails.large 
   ... 
 ``` 

 or 

 ```ruby ```rb 
 # Use ActiveSupport 
 if u.try!(:profile).try!(:thumbnails).try!(:large) 
  ... 
 ``` 
 I hope to write shortly above code. Groovy has above operator named "Safe navigation operator" with "`?.`" "?." syntax. 
 Ruby can't use "`?.`" "?." operator. 

 Can we use "`.?`" ".?" syntax. like this: 

 ```ruby ```rb 
 u = User.find(id) 
 u.?profile.?thumbnails.?large 
 ``` 

 Matz. How do you think about this?
