I am wondering if there is any difference between
and
Class: ERB (Ruby 2.1.1).
Is there any ?
I am reading - http://rrn.dk/rubys-erb-templating-system and
ERB - APIdock … Didn’t find any difference.

Humm… Xavier. I did it… #run calling #result inside it. No idea, why
then #run is needed in the API. That’s a my question. Because in CSV
module, I found lot’s of such things, where docs saying same, but they
are not. I found 1 bug, and some other wrong documentation. Verified by
JEGII, who used to tell you Ruby Hero

(#run and #result), but not documented.
I guess there is a misunderstanding somewhere, ERB#run says in its
documentation that it prints the result.
Maybe you interpret something else due to some issue with the English
sentence?

I know they are different library … I meant to say, currently I am not
taking any risks… May be something there between those 2 methods
(#run and #result), but not documented. So I asked here to experts, if
they have anything to share…

Yeah, you could just remove the method, but having the method is equally
valid.
Sometimes libraries have convenience methods like that, in Perl land for
example this one-liner is legendary:
perl -MLWP::Simple -e 'getprint "http://www.sn.no"'
Why getprint? Well, no big deal, the author just wanted to provide the
shortcut.

No, they are different.
run calls result and prints it, as in displays it on STDOUT.
result merely returns the processed input as a string.

Yes, In my case I was using puts with both, thus couldn’t catch the
difference. Now I tried as you said, got the difference :
#run
require ‘erb’
name = “Arup” # !> assigned but unused variable - name
template_string = “My name is <%= name %>”
template = ERB.new template_string
template.run
>> My name is Arup
#result
require ‘erb’
name = “Arup” # !> assigned but unused variable - name
template_string = “My name is <%= name %>”
template = ERB.new template_string
template.result # no output.
Thank you very much.
