Can any one help to correct the error which i got while using Rcs.pm in the Code

srins has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
I was using perl module Rcs for Revision Control System.In that i was using an method to retrive all my versions of Testcases.

my @all_testcase_versions=$rcsObj->revisions;
print "All Testcase Versions:@all_testcase_versions\n";
[download]

Output of that method is

All Testcase Versions:1.4 1.3 1.2 1.1
[download]

In that Module i was trying to get the file by giving versions as input
something as

To retrieve a specific version
my $specific_version = $rcsObj->get('1.2');
[download]

But this Functionality was not present in Rcs.pm,so i tried to parse that using Rcs::Parser Module.
But in Rcs::Parser Module they were using

  my $rcs = new RCS;
  my $ret = $rcs->load($filename);
  my $specific_version = $rcs->get('1.2');
[download]

But there was no RCS.pm module,but they have used as
my$rcs=new RCS;
I have changed that to
my $rcs=new Rcs;
in both my code and also in its Parser.pm file.But i am getting error as

Failed to retrieve revision info of test case - TC00631.xml due to sys
+tem error: Can't locate object method "load" via package "Rcs" line 1
+514.
[download]

I have also tried to use

 my $rcs = Rcs::Parser->new;
 my $ret = $rcs->load($rcstestcasename);
 my $specific_version = $rcs->get('1.2');
[download]

But i am not getting any Output.
Can any one help me in identifying what this my $rcs=new RCS;
Do i need to change anythign in my code.
OR,is there any module to retrive my files based on my version input.
Help needed to retrive my older files based on versions as input in CVS.
My Testcase in CVS is in Xml format.
say TC00631.xml and TC00631.xml,v

cat TC00631.xml,v
gives,
1.2

My Code is

    
use Rcs;
#use RCS;
use Rcs::Parser;
 # create a Rcs instance for the test case's revision info
        my $rcsObj = Rcs->new;
        $rcsObj->rcsdir(dirname($rcsDir));
        $rcsObj->workdir(dirname($rcsDir));
        $rcsObj->file($testCaseName);
        my $rcstestcasename=$rcsObj->file($testCaseName); 
        print "FileName:$rcstestcasename\n";

        # abstract interesting revision info
     my @all_testcase_versions=$rcsObj->revisions;
     print "All Testcase Versions:@all_testcase_versions\n";

        my $rcs = Rcs::Parser->new;
        my $ret = $rcs->load($rcstestcasename);
        my $specific_version = $rcs->get('1.2');
        print "1.2version:$specific_version\n";

    }; # end of eval

Can any one help in this regard.

Srins.

From looking at the module on CPAN, you have the right capitalization: it's `use Rcs`, not `use RCS` (although I don't see `use RCS` in the documentation -- maybe you have an old version?) As to what you're trying to do: I haven't used RCS in a while, but as far as I know, there is no `rcs get` command. If you want the text of the file at the particular revision, it looks like you should be doing something like this: `my $rcs = Rcs->new; # guessing the next line from your question $rcs->file($testCaseName); # equivalent to running "co -r 1.2" on the command line; # that is, will retrieve version 1.2 without locking. $rcs->co("-r" => "1.2");` [download] At this point, the working file should contain the text of the file at the specific version. Since you know its directory and its name, you can manipulate it like any other file. Caveat: I haven't tested this code, and it's based on an old recollection of RCS. But I hope it will help point you in the right direction. Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.	[reply] [d/l] [select]
