RCS must be installed on the system prior to using this module. This module should simplify the creation of an RCS front-end. =head2 OBJECT CONSTRUCTOR The B method may be used as either a class method or an object method to create a new object. # called as class method $obj = Rcs->new; # called as object method $newobj = $obj->new; =head2 CLASS METHODS Besides the object constructor, there are three class methods provided which effect any newly created objects. The B method sets the RCS archive extension, which is ',v' by default. # set/unset RCS archive extension Rcs->arcext(''); # set no archive extension Rcs->arcext(',v'); # set archive extension to ',v' $arc_ext = Rcs->arcext(); # get current archive extension The B method sets the directory path where the RCS executables (i.e. rcs, ci, co) are located. The default location is '/usr/local/bin'. # set RCS bin directory Rcs->bindir('/usr/bin'); # access RCS bin directory $bin_dir = Rcs->bindir; The B method sets/unsets the quiet mode for the RCS executables. Quiet mode is set by default. # set/unset RCS quiet mode Rcs->quiet(0); # unset quiet mode Rcs->quiet(1); # set quiet mode # access RCS quiet mode $quiet_mode = Rcs->quiet; These methods may also be called as object methods. $obj->arcext(''); $obj->bindir('/usr/bin'); $obj->quiet(0); =head2 OBJECT ATTRIBUTE METHODS These methods set the attributes of the RCS object. The B method is used to set the name of the RCS working file. The filename must be set before invoking any access of modifier methods on the object. $obj->file('mr_anderson.pl'); The B method is used to set the name of the RCS archive file. Using this method is optional, as the other methods will assume the archive filename is the same as the working file unless specified otherwise. The RCS archive extension (default ',v') is automatically added to the filename. $obj->arcfile('principle_mcvicker.pl'); The B methods set the path of the RCS working directory. If not specified, default path is '.' (current working directory). $obj->workdir('/usr/local/source'); The B methods set the path of the RCS archive directory. If not specified, default path is './RCS'. $obj->rcsdir('/usr/local/archive'); =head2 RCS PARSE METHODS This class provides methods to directly parse the RCS archive file. The B method returns a list of all user on the access list. @@access_list = $obj->access; The B method returns the author of the revision. The head revision is used if no revision argument is passed to method. # returns the author of revision '1.3' $author = $obj->author('1.3'); # returns the authos of the head revision $author = $obj->author; The B method returns the head revision. $head = $obj->head; The B method returns the locker of the revision. The method returns null if the revision is unlocked. The head revision is used if no revision argument is passed to method. # returns locker of revision '1.3' $locker = $obj->lock('1.3'); # returns locker of head revision $locker = $obj->lock; The B method returns a list of all revisions of archive file. @@revisions = $obj->revisions; The B method returns the state of the revision. The head revision is used if no revision argument is passed to method. # returns state of revision '1.3' $state = $obj->state('1.3'); # returns state of head revision $state = $obj->state; The B method returns the symbol(s) associated with a revision. If called in list context, method returns all symbols associated with revision. If called in scalar context, method returns last symbol assciated with a revision. The head revision is used if no revision argument is passed to method. # list context, returns all symbols associated with revision 1.3 @@symbols = $obj->symbol('1.3'); # list context, returns all symbols associated with head revision @@symbols = $obj->symbol; # scalar context, returns last symbol associated with revision 1.3 $symbol = $obj->symbol('1.3'); # scalar context, returns last symbol associated with head revision $symbol = $obj->symbol; The B method returns a hash, keyed by symbol, of all of the revisions associated with the file. %symbols = $obj->symbols; foreach $sym (keys %symbols) { $rev = $symbols{$sym}; } The B method returns the date of a revision. The returned date format is the same as the localtime format. When called as a scalar, it returns the system date number. If called is list context, the list ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) is returned. # scalar mode $scalar_date = $obj->revdate; print "Scalar date number = $scalar_date\n"; $date_str = localtime($scalar_date); print "Scalar date string = $date_str\n"; # list mode @@list_date = $obj->revdate; print "List date = @@list_date\n"; The B method returns a hash of revision dates, keyed on revision. The hash values are system date numbers. When called in scalar mode, the method returns the most recent revision date. # list mode %DatesHash = obj->dates; @@dates_list = sort {$b<=>$a} values %DatesHash; $MostRecent = $dates_list[0]; # scalar mode $most_recent = $obj->dates; print "Most recent date = $most_recent\n"; $most_recent_str = localtime($most_recent); print "Most recent date string = $most_recent_str\n"; The B method returns the revision against which a specified symbol was defined. If the symbol was not defined against any version of this file, 0 is returned. # gets revision that has 'MY_SYMBOL' defined against it $rev = symrev('MY_SYMBOL'); The B method returns a revision which was current at a specified date/time. If all revisions are newer than the specified date/time, i.e. the file did not exist then, 0 is returned. # gets revision that was active on 25th June 1998 16:45:30 $rev = daterev(1998, 6, 25, 16, 45, 30); The B method returns a hash of revision comments, keyed on revision. A key value of 0 returns the description. %comments = $obj->comments; $description = $comments{0}; $comment_1_3 = $comments{'1.3'}; =head2 RCS SYSTEM METHODS These methods invoke the RCS system utilities. The B method calls the RCS ci program. # check in, and then check out in unlocked state $obj->ci('-u'); The B method calls the RCS co program. # check out in locked state $obj->co('-l'); The B method calls the RCS rcs program. # lock file $obj->rcs('-l'); The B method calls the RCS rcsdiff program. When called in list context, this method returns the outpout of the rcsdiff program. When called in scalar context, this method returns the return status of the rcsdiff program. The return status is 0 for the same, 1 for some differences, and 2 for error condition. When called without parameters, rcsdiff does a diff between the current working file, and the last revision checked in. # call in list context @@diff_output = $obj->rcsdiff; # call in scalar context $changed = $obj->rcsdiff; if ($changed) { print "Working file has changed\n"; } Call rcsdiff with parameters to do a diff between any two revisions. @@diff_output = $obj->rcsdiff('-r1.2', '-r1.1'); The B method calls the RCS rlog program. This method returns the output of the rlog program. # get complete log output @@rlog_complete = $obj->rlog; # called with '-h' switch outputs only header information @@rlog_header = $obj->rlog('-h'); print @@rlog_header; The B method calls the RCS rcsclean program. # remove working file $obj->rcsclean; =head1 EXAMPLES =head2 CREATE ACCESS LIST Using method B with the B<-a> switch allows you to add users to the access list of an RCS archive file. use Rcs; $obj = Rcs->new; $obj->rcsdir("./project_tree/archive"); $obj->workdir("./project_tree/src"); $obj->file("cornholio.pl"); Methos B invokes the RCS utility rcs with the same parameters. @@users = qw(beavis butthead); $obj->rcs("-a@@users"); Calling method B returns list of users on access list. $filename = $obj->file; @@access_list = $obj->access; print "Users @@access_list are on the access list of $filename\n"; =head2 PARSE RCS ARCHIVE FILE Set class variables and create 'RCS' object.

Set bin directory where RCS programs (e.g. rcs, ci, co) reside. The default is '/usr/local/bin'. This sets the bin directory for all objects. use Rcs; Rcs->bindir('/usr/bin'); Rcs->quiet(0); # turn off quiet mode $obj = Rcs->new; Set information regarding RCS object. This information includes name of working file, directory of working file ('.' by default), and RCS archive directory ('./RCS' by default). $obj->file('cornholio.pl'); # Set RCS archive directory, is './RCS' by default $obj->rcsdir("./project_tree/archive"); # Set working directory, is '.' by default $obj->workdir("./project_tree/src"); Check in file using B<-u> switch. This will check in the file, and will then check out the file in an unlocked state. The B<-m> switch is used to set the revision comment. Command: $obj->ci('-u', '-mRevision Comment'); is equivalent to commands: $obj->ci('-mRevision Comment'); $obj->co; =head2 CHECK-OUT FILE Set class variables and create 'RCS' object. Set bin directory where RCS programs (e.g. rcs, ci, co) reside. The default is '/usr/local/bin'.
