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. - - -############### Globals ################ - - -# What we run to generate it: -my $Log_Source_Command = "cvs log"; - -# In case we have to print it out: -my $VERSION = '$Revision$'; -$VERSION =~ s/\S+\s+(\S+)\s+\S+/$1/; - -## Vars set by options: - -# Print debugging messages? -my $Debug = 0; - -# Just show version and exit? -my $Print_Version = 0; - -# Just print usage message and exit? -my $Print_Usage = 0; - -# Single top-level ChangeLog, or one per subdirectory? -my $Distributed = 0; - -# What file should we generate (defaults to "ChangeLog")? -my $Log_File_Name = "ChangeLog"; - -# Grab most recent entry date from existing ChangeLog file, just add -# to that ChangeLog. -my $Cumulative = 0; - -# Expand usernames to email addresses based on a map file? -my $User_Map_File = ""; - -# Output to a file or to stdout? -my $Output_To_Stdout = 0; - -# Eliminate empty log messages? -my $Prune_Empty_Msgs = 0; - -# Don't call Text::Wrap on the body of the message -my $No_Wrap = 0; - -# Separates header from log message.

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 -?

Basic usage: just run it inside a working copy and a -ChangeLog will appear.  It requires repository access (i.e., 'cvs log' -must work).

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... |
