Invoking from within code fails

[rpattcorner]

Probably an error on my part, but ...

Invoking byebug from shell works fine, e.g.

byebug -- myprogram.rb --option1

However inserting the command

byebug

in ruby code results in, for example:

[root@ip-10-0-1-100 deploy]# ruby sshtest.bb.rb
sshtest.bb.rb:9:in <main>': undefined local variable or methodbyebug' for main:Object (NameError)

Code looks like:

[root@ip-10-0-1-100 deploy]# cat sshtest.bb.rb
require 'net/http'
require 'json'
require 'rexml/document'

require 'net/ssh'
require 'net/ssh/multi'

connect_fail_retries = 0;
byebug
begin
puts "before do",connect_fail_retries
...

What obvious thing am I missing?
Documentation says to just insert

[deivid-rodriguez]

Yes, maybe the documentation is not very clear regarding this. You need to require byebug before calling byebug, but if you use bundler it will take care of that for you.

In your case, you can do

ruby -rbyebug sshtest.bb.rb

to tell the ruby to require it before running your program.

Thanks so much Deivid … that completely fixed the problem! Apologies for the simplicity of the question …

You are welcome @rpattcorner , no need to apologize!

@deivid-rodriguez I would recommend adding the require 'byebug' bit to the documentation.

I fell in the same trap, however require 'byebug' failed with with a 'cannot load such file' error even thought the gem was installed. But adding it to the Gemfile worked.
