#51706: platform statement: support an else clause --------------------------+-------------------------------- Reporter: rjvbertin@… | Owner: macports-tickets@… Type: enhancement | Status: new Priority: Normal | Milestone: Component: base | Version: Resolution: | Keywords: haspatch Port: | --------------------------+-------------------------------- Changes (by ryandesign@…): * keywords: => haspatch Old description:

As discussed on the ML a short while ago:

This patch introduces support for an else clause in the `platform` statement. Typical use would a port that needs to distinguish between 2 OS versions that require mutually exclusive treatment in multiple locations. With an else clause means that can be done without duplicating platform statements and without resorting to if/else constructs with their less elegant syntax in the test expression.

I haven't tested this yet but it might actually be possible to chain the commands:

``` platform darwin 10 { # older } [else] platform darwin 11 { # old } else { # younger } ```

If this is considered acceptable for a future MacPorts base version I'd really like to request a temporary vector to provide the new syntax ASAP, for instance through a PortGroup file.
