OT: "show run" parser

Ruby
1

Dear Rubyists,
I realize this is a fairly off-topic question, but I’m wondering if any
of you know of a tool that can read the output of “show run” (like in a
Cisco switch), parse the output, and produce a nice-looking document.

Anything perchance written in Ruby?

Thanks much!

I don’t know the “show run” command and what you want to parse out
of it. I guess the information you like to retrieve is not that
complicated.

show run.grep /^col1/

It’s difficult to have a generic tool for Cisco configs considering the
vast
number of options there can be and the somewhat idiosyncratic format
they each
come in!

You may find something here: http://cosi-nms.sourceforge.net/

Unlikely to be any in Ruby though.

I have seen the occassional conversion s/w on the web but I have no
references.

It depends a lot on what you mean by “nice looking document” of course.
Presumably you want to extract only certain portions for display.
I wrote a reasonably generic parser in Python some time ago, it
basically
looked for indented sections and common prefixes and specifically
checked for
the sort of thing we have on our routers. I could try and dig it out if
you’re interested (email me). I also started an extendable parser in
Ruby but
it’s far from done and it was the first non-trivial Ruby program I wrote
so
it’s probably very bad Ruby style (it’s probably also way over the top
since
it was for analysing the contents of Pix configs).
