I am running the following command in linux to generate a verbose log for a particular revision.
svn log -v -r12345 http://svn-remote.com/path
The output is:

BUG ID 12345678 - BLAH IMPLEMENTATION IN PROJECT.CYCLE
------------------------------------------------------------------------
I want to parse this log output the package names for each of those files. Eg:
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleGroupTask.java
How to write the perl or python or a shell script to do that so that the usage can be like this for example:
$ perl svnlog.pl 12345 > log.txt
This is a version that will run svn log and parse the output.
Of course I don't have your repo so I had to fake the command and output by just cating your output but it works.
use strict;
my $revno = shift @ARGV;
die "Usage: $0: svn-revision\n" unless $revno;
my $cmd = "svn log -v -r$revno 'http://svn-remote.com/path'";
open(SVN,"$cmd |") or die "Command '$cmd' Failed : $!\n";
while(<SVN>) {
chomp;
if ( /^\s+\S\s\/([^\/]+\/[^\/]+).*[^\/]$/ ) {
(my $tag = $1) =~ s!/!.!g;
s!.*/src/main/java/!!;
my @a = split(/\//);
my $file = pop @a;
print $tag, " ", join(".", @a), " ", $file, "\n";
}
}
My test output.
PROJECT.CYCLE com.companyname.cycle.agent Main.java
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleGroupTask.java
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleProcessTaskBll.java
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleSequenceProcessTaskBll.java
PROJECT.CYCLE com.companyname.cycle.test.bll MockCycleBll.java
PROJECT.CYCLE com.companyname.pas.cycle.bll DasCycleBll.java
PROJECT.CYCLE com.companyname.pas.cycle.dal DasCycleDal.java
A maven repo would have a src/test/java directory too :D, I presume you're not interested in them.
EDIT
Running the body of the Perl against your data basically adding my $cmd = "sh fake.sh"; from the other question produces:
PROJECT.CYCLE com.companyname.cycle.agent Main.java
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleGroupTask.java
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleProcessTaskBll.java
PROJECT.CYCLE com.companyname.cycle.agent.bll.tasks CycleSequenceProcessTaskBll.java
PROJECT.CYCLE com.companyname.cycle.test.bll MockCycleBll.java

PROJECT.SHARED com.companyname.extensibility.helper ExtensionConfigurationHelper.java
PROJECT.SRE com.companyname.ext DocumentGeneratorExt.java
PROJECT.SRE com.companyname.ext NamedExtensionPoint.java
PROJECT.SRE com.companyname.ext SystemDateBll.java
MODULE.CYCLE com.companyname.extensibility FileCycle1.java
MODULE.CYCLE com.companyname.extensibility FileCycle2.java
Which seems to be what the OP wants in the other question.
So the issue would be looping around the body of the Perl once for each $revno.
foreach my $revno (@ARGV) {
print $revno, "\n";
}
EDIT changing the body of the code group by module to be...
my %info;
while(<SVN>) {
chomp;
if ( /^\s+\S\s\/([^\/]+\/[^\/]+).*[^\/]$/ ) {
(my $tag = $1) =~ s!/!.!g;
s!.*/src/main/java/!!;
my @a = split(/\//);
my $file = pop @a;
print $tag, " ", join(".", @a), " ", $file, "\n";
push @{$info{$tag}}, join(" ", join(".", @a), $file);
#push @{$info{$tag}}, $file;
}
}
while ( my ($key, $value) = each %info )
{
print "$key\n";
for my $line ( @{$info{$key}} ) {
print "\t", $line, "\n";
}
}
produces this on the data previously given.
PROJECT.SHARED
com.companyname.extensibility NamedExtensionPoint.java
com.companyname.extensibility PrePostExtensionPoint.java
com.companyname.extensibility.helper ExtensionConfigurationHelper.java
PROJECT.CYCLE
com.companyname.cycle.agent Main.java

com.companyname.extensibility FileCycle2.java
PROJECT.SRE
com.companyname.ext DocumentGeneratorExt.java
com.companyname.ext NamedExtensionPoint.java
com.companyname.ext SystemDateBll.java
Which should go someway to helping the OP achieve what they want.
I think your java project is maven project:
awk -F'src/main/java/' 'NF==2{split($1,a,"/");j=p=$2;sub(/.*\//,"",j);sub("/[^/]*$","",p);gsub("/",".",p);print a[2]"."a[3],p,j}' yourlog
test with your example:
kent$ cat f1
