Parse file to a hash

ruby-talk
1

Hello!

I need to parse a specific file to a hash. This is a sample of the file:

blablabla......
}
    -- 1.3.6.1.4.1.000.6.1.2.2.11.1
    mASLocked OBJECT-TYPE
      SYNTAX INTEGER
......blablabla

And my hash has to be like this:

my_hash = {
'mASLocked' => '1.3.6.1.4.1.000.6.1.2.2.11.1'
}

The hash will have about 400 items on it.

The only 2 things that are standard on the file are the '-- ' before the
number and the string 'OBJECT-TYPE' on the second line.

I saw a lot of parse examples but they always use something like DATA
SEPARATION DATA. This is not my case since the identifier is in one line
before the data and in the other line after the data I want.

I am thinking of doing something very ugly here. Any ideas to save me
from do a ugly Frankenstein (and probably wrong) code?

Thanks

You might try String#scan with a multiline regex.

text =<<EOF
   -- 1.3.6.1.4.1.000.6.1.2.2.11.1
   mASLocked OBJECT-TYPE
     SYNTAX INTEGER
EOF

hash = Hash.new

regex = /-- (.+)\n\s+(.+) OBJECT-TYPE/m

text.scan(regex) do |value,key|
  hash[key] = value
end

p hash

p hash
