Debian::Rules(3pm) User Contributed Perl Documentation Debian::Rules(3pm) NAME
Debian::Rules - handy manipulation of debian/rules SYNOPSIS
my $r = Debian::Rules->new('debian/rules'); my $r = Debian::Rules->new( { filename => 'debian/rules' } ); $r->is_dh7tiny && print "Using the latest and greatest "; $r->is_quiltified && print "quilt rules the rules "; # file contents changed externally $r->parse; $r->add_quilt; $r->drop_quilt; $r->write; # or undef($r); DESCRIPTION
Some times, one needs to know whether debian/rules uses the debhelper(1) 7 tiny variant, or whether it is integrated with quilt(1). Debian::Rules provides facilities to check this, as well as adding/removing quilt integration. Modified contents are written to file either vie the "write" method, or when the object reference goes out of scope (via DESTROY). CONSTRUCTOR
"new" is the standard Class::Accessor constructor, with the exception that if only one, non-reference argument is provided, it is treated as a value for the filename field. If a file name is given, the constructor calls "read" to read the file contents into memory. One of filename or lines is mandatory. FIELDS
filename Contains the file name of the rules file. lines Reference to an array pointing to the rules file. Initialized by "new". METHODS
parse Parses the rules file and stores its findings for later use. Called automatically by is_dh7tiny and is_quiltified. The result of the parsing is cached and subsequent calls to "is_XXX" use the cache. To force cache refresh (for eample if the contents of the file have been changed), call "parse" again. is_dh7tiny Returns true if the contents of the rules file seem to use the so called tiny variant offerred by debhelper 7. Tiny rules are detected by the presense of the following two lines: %: dh $@ (any options on the "dh" command line ignored). is_quiltified Returns true if the contents of the rules file indicate that quilt(1) is used. Various styles of "quilt" integration are detected: dh --with=quilt quilt.make with "$(QUILT_STAMPFN)" and "unpatch" targets. add_quilt Integrates quilt(1) into the rules. For debhelper 7 tiny rules (as determined by "is_dh7tiny") "--with=quilt" is added to every "dh" invocation. For the more traditional variant, quilt is integrated vua quilt.make and its "$(QUILT_STAMPFN)" and "unpatch" targets. drop_quilt Removes quilt(1) integration. Both debhelper 7 tiny style ("dh --with=quilt") and traditional ("$(QUILT_STAMPFN)" and "unpatch") approaches are detected and removed. read [filename] Replaces the current rules content with the content of filename. If filename is not given, uses the value of the "filename" member. write [filename] Writes the in-memory contents filename. If not given, uses the value of the "filename" member. If "lines" points to an empty array, the file is removed.
