echo back every Ruby code line like sh -x?

Is there a way to have a ruby script echo back (or log to file I can tail -f) every line executed, similar to bash -x or @echo on in DOS?

ruby -w doesn't do it--only increases verbosity of warnings etc.

Researched Unroller but it doesn't work, possibly too dated. Uncompilable dependencies.

I use irb a lot but in this case I need something non-interactive eg. to inspect post-mortem.

Solution

  • You can use

    ruby -rtracer [your_script.rb]

    There is also ruby-debug which can do

    rdebug --trace [your_script.rb]
