Feature #21105

Updated by ennder (Jérôme BATAILLE) 4 days ago

## Subject 

 Improve Ruby Stack Trace to Include Exact Error Position (Column Number) 

 ## Description 

 Currently, when an exception occurs in Ruby, the stack trace provides the file name and line number but does not indicate the exact position (column number) where the error occurred within the line. This lack of precision can make debugging more challenging, especially in cases where multiple method calls or expressions are present on the same line. 

 ## Example 

 ``` ruby 
 class Example 
   def self.run 
     nil.some_method_call    # Error occurs here 
   end 
 end 

 Example.run 
 </code></pre> 
 ``` 

 ## Expected Behavior 

 The stack trace should include the column number where the error occurred, e.g.: 

 ``` ruby 
 trace.rb:4:10:in `run': undefined method `some_method_call' for nil:NilClass (NoMethodError) 
 ``` 


 ## Benefits 

 More precise debugging. 

 Easier identification of errors in complex one-liner expressions. 

 Better tooling support for editors and debuggers. 

 ## Additional Notes 

 Would it be possible to add this enhancement in a future Ruby version? 

 Thank you for considering this request!
