# The Plan:
 | 
						||
#
 | 
						||
# Read in the logs for multiple files, spit out a nice ChangeLog that
 | 
						||
# mirrors the information entered during `cvs commit'.
 | 
						||
#
 | 
						||
# The problem presents some challenges. In an ideal world, we could
 | 
						||
# detect files with the same author, log message, and checkin time --
 | 
						||
# each <filelist, author, time, logmessage> would be a changelog entry.
 | 
						||
# We'd sort them; and spit them out.  Unfortunately, CVS is *not atomic*
 | 
						||
# so checkins can span a range of times.  Also, the directory structure
 | 
						||
# could be hierarchical.
 | 
						||
#
 | 
						||
# Another question is whether we really want to have the ChangeLog
 | 
						||
# exactly reflect commits. An author could issue two related commits,
 | 
						||
# with different log entries, reflecting a single logical change to the
 | 
						||
# source. GNU style ChangeLogs group these under a single author/date.
 | 
						||
# We try to do the same.
 | 
						||
#
 | 
						||
# So, we parse the output of `cvs log', storing log messages in a
 | 
						||
# multilevel hash that stores the mapping:
 | 
						||
#   directory => author => time => message => filelist
 | 
						||
# As we go, we notice "nearby" commit times and store them together
 | 
						||
# (i.e., under the same timestamp), so they appear in the same log
 | 
						||
# entry.
 | 
						||
#
 | 
						||
# When we've read all the logs, we twist this mapping into
 | 
						||
# a time => author => message => filelist mapping for each directory.
 | 
						||
#
 | 
						||
# If we're not using the `--distributed' flag, the directory is always
 | 
						||
# considered to be `./', even as descend into subdirectories.

Generate GNU-style ChangeLogs in CVS working copies.
 | 
						||
 | 
						||
Notes about the output format(s):
 | 
						||
 | 
						||
   The default output of cvs2cl.pl is designed to be compact, formally
 | 
						||
   unambiguous, but still easy for humans to read.  It is largely
 | 
						||
   self-explanatory, I hope; the one abbreviation that might not be
 | 
						||
   obvious is "utags".  That stands for "universal tags" -- a
 | 
						||
   universal tag is one held by all the files in a given change entry.
 | 
						||
 | 
						||
   If you need output that's easy for a program to parse, use the
 | 
						||
   --xml option.  Note that with XML output, just about all available
 | 
						||
   information is included with each change entry, whether you asked
 | 
						||
   for it or not, on the theory that your parser can ignore anything
 | 
						||
   it's not looking for.
 | 
						||
 | 
						||
Notes about the options and arguments (the actual options are listed
 | 
						||
last in this usage message):
 | 
						||
 | 
						||
  * The -I and -F options may appear multiple times.
 | 
						||
 | 
						||
  * To follow trunk revisions, use "-F trunk" ("-F TRUNK" also works).
 | 
						||
    This is okay because no would ever, ever be crazy enough to name a
 | 
						||
    branch "trunk", right?  Right.
 | 
						||
 | 
						||
  * For the -U option, the UFILE should be formatted like
 | 
						||
    CVSROOT/users. That is, each line of UFILE looks like this
 | 
						||
       jrandom:jrandom@red-bean.com
 | 
						||
    or maybe even like this
 | 
						||
       jrandom:'Jesse Q. Random <jrandom@red-bean.com>'
 | 
						||
    Don't forget to quote the portion after the colon if necessary.
 | 
						||
  
 | 
						||
  * Many people want to filter by date.  To do so, invoke cvs2cl.pl
 | 
						||
    like this: 
 | 
						||
       cvs2cl.pl -l "-d'DATESPEC'"
 | 
						||
    where DATESPEC is any date specification valid for "cvs log -d".
 | 
						||
    (Note that CVS 1.10.7 and below requires there be no space between
 | 
						||
    -d and its argument).
 | 
						||
 | 
						||

 | 
						||

=head1 NAME
 | 
						||
 | 
						||
cvs2cl.pl - produces GNU-style ChangeLogs in CVS working copies, by
 | 
						||
    running "cvs log" and parsing the output.  Shared log entries are
 | 
						||
    unified in an intuitive way.
 | 
						||
 | 
						||
=head1 DESCRIPTION
 | 
						||
 | 
						||
This script generates GNU-style ChangeLog files from CVS log
 | 
						||
information.  Basic usage: just run it inside a working copy and a
 | 
						||
ChangeLog will appear.  It requires repository access (i.e., 'cvs log'
 | 
						||
must work).  Run "cvs2cl.pl --help" to see more advanced options.
 | 
						||
 | 
						||
See http://www.red-bean.com/~kfogel/cvs2cl.shtml for updates, and
 | 
						||
for instructions on getting anonymous CVS access to this script.

Note about a bug-slash-opportunity:
 | 
						||
-----------------------------------
 | 
						||
 | 
						||
There's a bug in Text::Wrap, which affects cvs2cl.  This script
 | 
						||
reveals it:
 | 
						||
 | 
						||
  #!/usr/bin/perl -w
 | 
						||
  
 | 
						||
  use Text::Wrap;
 | 
						||
  
 | 
						||
  my $test_text =
 | 
						||
  "This script demonstrates a bug in Text::Wrap.  The very long line
 | 
						||
  following this paragraph will be relocated relative to the surrounding
 | 
						||
  text:
 | 
						||
  
 | 
						||
  ====================================================================
 | 
						||
  
 | 
						||
  See?  When the bug happens, we'll get the line of equal signs below
 | 
						||
  this paragraph, even though it should be above.";
 | 
						||
  
 | 
						||
  
 | 
						||
  # Print out the test text with no wrapping:
 | 
						||
  print "$test_text";
 | 
						||
  print "\n";
 | 
						||
  print "\n";
 | 
						||
  
 | 
						||
  # Now print it out wrapped, and see the bug:
 | 
						||
  print wrap ("\t", "        ", "$test_text");
 | 
						||
  print "\n";
 | 
						||
  print "\n";
 | 
						||
 | 
						||
If the line of equal signs were one shorter, then the bug doesn't
 | 
						||
happen.  Interesting.
 | 
						||
 | 
						||
Anyway, rather than fix this in Text::Wrap, we might as well write a
 | 
						||
new wrap() which has the following much-needed features:
 | 
						||
 | 
						||
* initial indentation, like current Text::Wrap()
 | 
						||
* subsequent line indentation, like current Text::Wrap()
 | 
						||
* user chooses among: force-break long words, leave them alone, or die()?
 | 
						||
* preserve existing indentation: chopped chunks from an indented line
 | 
						||
  are indented by same (like this line, not counting the asterisk!)
 | 
						||
* optional list of things to preserve on line starts, default ">"
 | 
						||
 | 
						||
Note that the last two are essentially the same concept, so unify in
 | 
						||
implementation and give a good interface to controlling them.
 | 
						||
 | 
						||
And how about:
 | 
						||
 | 
						||
Optionally, when encounter a line pre-indented by same as previous
 | 
						||
line, then strip the newline and refill, but indent by the same.
 | 
						||
Yeah...
