genpatch was also depending on the new files being listed first by
'cvs diff' (which is the case but I'm not sure there is any hard
guarantee).
Use 'perl -w' for more checking, fix the resulting 'undefined value'
warnings. In many cases we don't just want $options{xxx} to exist, we
want it to be defined.
Restrict the scope of variables and remove unneeded variables.

genpatch - A utility that generates patches for submission to
|
|
wine-patches@winehq.org
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
genpatch [B<-v>] [B<-n> patch_name] [B<-f> patch_file]
|
|
[B<-c> change_log] [B<-m> modified_files]
|
|
[B<-a> added_files]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The genpatch utility generated patches for submission to
|
|
wine-patches@winehq by acting as a wrapper to "cvs diff". The "B<-v>"
|
|
switch specifies that verbose output should be generated. The "B<-n>"
|
|
switch overrides the patch name ("Name" field) which defaults to a
|
|
numeric UTC date. The "B<-f>" switch overrides the filename of the patch
|
|
which defaults to "patches/<patch_name>.diff". The "B<-c>" switch
|
|
specifies the CVS change log entry ("ChangeLog" field) which can be
|
|
seen when "cvs log" is invoked. The "B<-m>" ("ModifiedFiles" field) and
|
|
"B<-a>" ("AddedFiles" field) switches override the set of files that
|
|
would normally be included by the "cvs diff". Normally "cvs diff"
|
|
includes all files modified relative to the deltas indicated by the
|
|
"CVS/Entries" file and ignores all newly added files. The "B<-m>" switch
|
|
specifies a whitespace separated list of files that were modified.
|
|
The "B<-a>" switch specifies a whitespace separated list of files that
|
|
were added.
|
|
|
|
=head1 EXAMPLE
|
|
|
|
genpatch B<-n> NLSFix B<-c> "various fixes for NLS support" \
|
|
B<-m> ole/ole2nls.c B<-a> ole/ole3nls.c
|
|
|
|
The above generates a patch named "NLSFix" in "patches/NLSFix.diff"
|
|
that includes a modification to "ole/ole2nls.c" and a newly added
|
|
"ole/ole3nls.c".
