#11873: Need alternate floating point version comparison function for perl5 portgroup ports ---------------------------------+------------------------------------------ Reporter: vinc17@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: MacPorts 1.9.0 Component: base | Version: Keywords: | Port: ---------------------------------+------------------------------------------ Changes (by raimue@…): * cc: raimue@… (added) Comment: Instead of inventing a different comparison function, we should just convert the version number to something compatible. The rpm-based Linux distribution Mandriva does this as of 2009. As we are using the same rpm version comparison algorithm, this would be compatible. They are using a macro %perl_convert_version which would be equivalent to: {{{ $ perl -Mversion -le '$v=version->new(1.337)->normal; $v=~s/^v//; print $v' }}} For more information refer to `perldoc version`. I propose that `perl5.setup` in the perl5 PortGroup should convert the version and set the `version` option converted. Additionally there could be a `perl5.module_version` variable local to the Portfile for use at other places in the Portfile (`perl5.version` is already in use). {{{ perl5.setup Foo-Bar 1.337 # => name p5-foo-bar # => version 1.337.0 # => perl5.module_version 1.337 }}} {{{ perl5.setup Foo-Bar 1.4 # => name p5-foo-bar # => version 1.400.0 # => perl5.module_version 1.4 }}} There needs to be a decision if we want to call out to the perl binary for this conversion or if we should implement the same in Tcl or C. -- Ticket URL: <http://trac.macports.org/ticket/11873#comment:19> MacPorts <http://www.macports.org/> Ports system for Mac OS
