# 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).
|
||
|
||
Options/Arguments:
|
||
|
||
-h, -help, --help, or -? Show this usage and exit
|
||
--version Show version and exit
|
||
-r, --revisions Show revision numbers in output
|
||
-b, --branches Show branch names in revisions when possible
|
||
-t, --tags Show tags (symbolic names) in output
|
||
--stdin Read from stdin, don't run cvs log
|
||
--stdout Output to stdout not to ChangeLog
|
||
-d, --distributed Put ChangeLogs in subdirs
|
||
-f FILE, --file FILE Write to FILE instead of "ChangeLog"
|
||
-W SECS, --window SECS Window of time within which log entries unify
|
||
-U UFILE, --usermap UFILE Expand usernames to email addresses from UFILE
|
||
-R REGEXP, --regexp REGEXP Include only entries that match REGEXP
|
||
-I REGEXP, --ignore REGEXP Ignore files whose names match REGEXP
|
||
-C, --case-insensitive Any regexp matching is done case-insensitively
|
||
-F BRANCH, --follow BRANCH Show only revisions on or ancestral to BRANCH
|
||
-S, --separate-header Blank line between each header and log message
|
||
--gmt, --utc Show times in GMT/UTC instead of local time
|
||
-w, --day-of-week Show day of week
|
||
--header FILE Get ChangeLog header from FILE ("-" means stdin)
|
||
--xml Output XML instead of ChangeLog format
|
||
-P, --prune Don't show empty log messages
|
||
-g OPTS, --global-opts OPTS Invoke like this "cvs OPTS log ..."
|
||
-l OPTS, --log-opts OPTS Invoke like this "cvs ... log OPTS"
|
||
FILE1 [FILE2 ...] Show only log information for the named FILE(s)

=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...
