Is there an easier way to parse into tokens a string?

Ruby
#1

Hello Team,

When running the piece of code below, I expect and get the following
line
of text, which comes as a one element array.
[“AMQ8409: Display Queue details.\n QUEUE(TEMP) TYPE(QLOCAL)\n
CURDEPTH(6)”]

I am only interested in the queue depth, which is pointed to by
CURDEPTH.
That number, which is 6 for case, is the only thing I want.
I convert that one element into a string and then parse (tokenize) it
using
the split method. As you can see it takes me 3 operations to get that
number.
Using my method below on a very long string will make it unmanageable.
Think of a string with few dozen words!
Is there a more simple Ruby way to parse the string and get what I want?

Bellow is the actual code.

Thank you

require ‘rubygems’
require ‘wmq’

WMQ::QueueManager.connect(:q_mgr_name=>‘WMQDEVA1’,
:connection_name => ‘test.host(1414)’,
:channel_name => ‘WMQDEVA1.ADM.SVRCONN’) do
|qmgr|

The next stmt returns an array of 1 element, which I convert to a

string

I am ONLY interested in the content of CURDEPTH, the number between

parenthesis

Actual output:

*["AMQ8409: Display Queue details.\n QUEUE(TEMP)

TYPE(QLOCAL)\n
CURDEPTH(6)"]*
cdepth = qmgr.mqsc(‘dis ql(TEMP) CURDEPTH’).to_s
v1,v2,v3,v4,v5,v6,v7 = cdepth.split(" “) # tokenize string to
isolate
CURDEPTH(6)
v1,v2 = v7.split(”(") # Remove left parenthesis
qdepth, gb = v2.split(")") # Remove right parenthesis
puts “CURDEPTH = #{qdepth}” # 6
end

Thank you

end

You could do it with a regular expression and a capturing group:

2.0.0-p195 :003 > s = “AMQ8409: Display Queue details.\n QUEUE(TEMP)
TYPE(QLOCAL)\n CURDEPTH(6)”
=> “AMQ8409: Display Queue details.\n QUEUE(TEMP)
TYPE(QLOCAL)\n CURDEPTH(6)”
2.0.0-p195 :005 > s[/CURDEPTH(([^)]*))/,1]
=> “6”

Jesus.
