An example is if I go into IRB and do the following:
jruby-1.6.7 :026 > puts [1,2,3,4,5]
1
2
3
4
5
=> nil
Is there anyway to suppress the nil? The problem is if I put in a large data structure, it spams something an other irrelevant return respond. I’m more interested in seeing output from debug statements I run through a block and have to continually scroll up and look for the real data.
If you just want to suppress long output once in a while, use
;0, like:If you want to suppress it generally, use the ~/.irbrc file. The IRB.conf[:INSPECT_MODE] and IRB.conf[:PROMPT][your_prompt][:RETURN] control what is returned. You can figure out what your_prompt is by checking IRB.conf[:PROMPT_MODE]
Example:
You’ll need to restart irb after changing the value.
