is there anyway to merge two facts into single one

[Spriya]

Hi ,

Is there any way to merge two facts into single facts.

Here is my facts

java_known_weblogic_version1	1.7.0_72
java_known_weblogic_version1_path	/u01/java/jdk1.7.0_72/jre/bin/java

I want to merge these two facts into single one 

I mean 

java_known_weblogic_version1 = 1.7.0_72//u01/java/jdk1.7.0_72/jre/bin/java

Like this

Anyone please help me

In what context, for what purpose?

Generally speaking, I'd say you should just concatenate the two fact values in the scope where the aggregate value is wanted, as opposed to modifying fact implementations to change what facter reports.  Is that unsuitable for some reason?

Hi,

The purpose  is i want to compare using the value to a txt file which contains 1.7.0_72//u01/java/jdk1.7.0_72/jre/bin/java this reason for that i want to concatenate.

Let me know your thoughts

If you have a fact called factA and a fact called factB, and you need factC to be a combination of both values, sure, that can be done.

I don't know what version of Facter you're using, but if you're using PE 3.7 + Facter 2.2.0, you can simply use Facter.value.

E.g:

Facter.add(:factC) do

  setcode do

    factC = "#{Facter.value('factA')}#{Facter.value('factB')}"

    factC

  end

end

That would return a factC that was the combined values of factA and factB.

For more, see the docs https://docs.puppetlabs.com/facter/2.2/custom_facts.html#using-other-facts

You could of course just combine the fact values in your puppet code as well, if that's appropriate...

`$value = "${one}${two}"` is perfectly valid Puppet code.

Thank you

Hi,

When i am concatenating using your method. Its only returning one values. It should have version in front of  path

Facter.add("java_foundversion#{java_count}_foundversion#{java_count}_path") do

 setcode do

    java_version[1] + java_path

end

end

The output of facts 

/opt/puppet/bin/facter -p | grep -i java_*        java_foundversion1_path => /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.65.x86_64/jre/bin/java

java_foundversion2_path => /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/bin/java

java_foundversion3_path => /opt/oracle/agent12c/core/12.1.0.4.0/jdk/bin/java

java_foundversion4_path => /opt/oracle/agent12c/core/12.1.0.4.0/jdk/jre/bin/java

java_foundversion5_path => /opt/itm/v6.2.2/JRE/lx8266/bin/java

java_foundversion6_path => /u01/java/jdk1.7.0_72/jre/bin/java

java_foundversion7_path => /u01/java/jdk1.7.0_72/bin/java

java_foundversion8_path => /u01/java/jdk1.7.0_65/jre/bin/java

java_foundversion9_path => /u01/java/jdk1.7.0_65/bin/java

If that's happening, then one of the facts must be returning nil.

Hi, 

I tried that also whether the fact is returing nil or by writing into separate facts

Here is the code:

Facter.add("java_foundversion#{java_count}_foundversion") do

 setcode do

    java_version[1]

end

end

#end

#end

#end

#end

Facter.add("java_foundversion#{java_count}_path") do

 setcode do

   java_path

end

end

end

end

My facts

java_foundversion1_foundversion => 1.7.0_65

java_foundversion1_path => /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.65.x86_64/jre/bin/java

java_foundversion2_foundversion => 1.6.0_32

java_foundversion2_path => /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/bin/java

java_foundversion3_foundversion => 1.6.0_43

java_foundversion3_path => /opt/oracle/agent12c/core/12.1.0.4.0/jdk/bin/java

But when i am concatenating the java_path is not returning.  Let me know your thoughts
