# 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.

# 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...

=head1 NAME
cvs2cl.pl - convert cvs log messages to changelogs
=head1 SYNOPSIS
B<cvs2cl> [I<options>] [I<FILE1> [I<FILE2> ...]]
=head1 DESCRIPTION
cvs2cl produces a GNU-style ChangeLog for CVS-controlled sources by
running "cvs log" and parsing the output. Duplicate log messages get
unified in the Right Way.
The default output of cvs2cl is designed to be compact, formally unambiguous,
but still easy for humans to read. It should be largely self-explanatory; 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 B<--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.
If filenames are given as arguments cvs2cl only shows log information for the
named files.
=head1 OPTIONS
=over 4
=item B<-h>, B<-help>, B<--help>, B<-?>
Show a short help and exit.
=item B<--version>
Show version and exit.
=item B<-r>, B<--revisions>
Show revision numbers in output.
=item B<-b>, B<--branches>
Show branch names in revisions when possible.
=item B<-t>, B<--tags>
Show tags (symbolic names) in output.
=item B<-T>, B<--tagdates>
Show tags in output on their first occurance.
=item B<--show-dead>
Show dead files.
=item B<--stdin>
Read from stdin, don't run cvs log.
=item B<--stdout>
Output to stdout not to ChangeLog.
=item B<-d>, B<--distributed>
Put ChangeLogs in subdirs.
=item B<-f> I<FILE>, B<--file> I<FILE>
Write to I<FILE> instead of ChangeLog.
=item B<--fsf>
Use this if log data is in FSF ChangeLog style.
=item B<--FSF>
Attempt strict FSF-standard compatible output.
=item B<-W> I<SECS>, B<--window> I<SECS>
Window of time within which log entries unify.
=item -B<U> I<UFILE>, B<--usermap> I<UFILE>
Expand usernames to email addresses from I<UFILE>.
=item B<--passwd> I<PASSWORDFILE>
Use system passwd file for user name expansion. If no mail domain is provided
(via B<--domain>), it tries to read one from B</etc/mailname>, output of B<hostname
-d>, B<dnsdomainname>, or B<domain-name>. cvs2cl exits with an error if none of
those options is successful. Use a domain of '' to prevent the addition of a
mail domain.
=item B<--domain> I<DOMAIN>
Domain to build email addresses from.
=item B<--gecos>
Get user information from GECOS data.
=item B<-R> I<REGEXP>, B<--regexp> I<REGEXP>
Include only entries that match I<REGEXP>. This option may be used multiple
times.
=item B<-I> I<REGEXP>, B<--ignore> I<REGEXP>
Ignore files whose names match I<REGEXP>. This option may be used multiple
times.
=item B<-C>, B<--case-insensitive>
Any regexp matching is done case-insensitively.
=item B<-F> I<BRANCH>, B<--follow> I<BRANCH>
Show only revisions on or ancestral to I<BRANCH>.
=item B<--no-ancestors>
When using B<-F>, only track changes since the I<BRANCH> started.
=item B<--no-hide-branch-additions>
By default, entries generated by cvs for a file added on a branch (a dead 1.1
entry) are not shown. This flag reverses that action.
=item B<-S>, B<--separate-header>
Blank line between each header and log message.
=item B<--summary>
Add CVS change summary information.
=item B<--no-wrap>
Don't auto-wrap log message (recommend B<-S> also).
=item B<--no-indent>
Don't indent log message
=item B<--gmt>, B<--utc>
Show times in GMT/UTC instead of local time.
=item B<--accum>
Add to an existing ChangeLog (incompatible with B<--xml>).
=item B<-w>, B<--day-of-week>
Show day of week.
=item B<--no-times>
Don't show times in output.
=item B<--chrono>
Output log in chronological order (default is reverse chronological order).
=item B<--header> I<FILE>
Get ChangeLog header from I<FILE> ("B<->" means stdin).
=item B<--xml>
Output XML instead of ChangeLog format.
=item B<--xml-encoding> I<ENCODING.>
Insert encoding clause in XML header.
=item B<--noxmlns>
Don't include xmlns= attribute in root element.
=item B<--hide-filenames>
Don't show filenames (ignored for XML output).
=item B<--no-common-dir>
Don't shorten directory names from filenames.
=item B<--rcs> I<CVSROOT>
Handle filenames from raw RCS, for instance those produced by "cvs rlog"
output, stripping the prefix I<CVSROOT>.
=item B<-P>, B<--prune>
Don't show empty log messages.
=item B<--ignore-tag> I<TAG>
Ignore individual changes that are associated with a given tag.
May be repeated, if so, changes that are associated with any of
the given tags are ignored.
=item B<--show-tag> I<TAG>
Log only individual changes that are associated with a given
tag. May be repeated, if so, changes that are associated with
any of the given tags are logged.
=item B<--delta> I<FROM_TAG>B<:>I<TO_TAG>
Attempt a delta between two tags (since I<FROM_TAG> up to and
including I<TO_TAG>). The algorithm is a simple date-based one
(this is a hard problem) so results are imperfect.
=item B<-g> I<OPTS>, B<--global-opts> I<OPTS>
Pass I<OPTS> to cvs like in "cvs I<OPTS> log ...".
=item B<-l> I<OPTS>, B<--log-opts> I<OPTS>
Pass I<OPTS> to cvs log like in "cvs ... log I<OPTS>".
=back
Notes about the options and arguments:
=over 4
=item *
The B<-I> and B<-F> options may appear multiple times.
=item *
To follow trunk revisions, use "B<-F trunk>" ("B<-F TRUNK>" also works). This is
okay because no would ever, ever be crazy enough to name a branch "trunk",
right? Right.
=item *
For the B<-U> option, the I<UFILE> should be formatted like CVSROOT/users. That is,
each line of I<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.
=item *
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).
=item *
Dates/times are interpreted in the local time zone.
=item *
Remember to quote the argument to `B<-l>' so that your shell doesn't interpret
spaces as argument separators.
=item *
See the 'Common Options' section of the cvs manual ('info cvs' on UNIX-like
systems) for more information.
=item *
Note that the rules for quoting under windows shells are different.
