port suggestion : clazy

[RJVB (René Bertin)]

This is a prototype port for clazy, a plugin and wrapper for clang that implements a static analyser with a number of predefined checks for typical coding errors. The provided checks are oriented to development using Qt (and KDE); some of them are actually able to correct the source code.

I've run into an issue writing the Portfile (again, in fact). The code below creates a reinplace command in which ${lv}=3.8 (i.e. the last value of the loop variable) for all subports. Is that a bug in "base", or simply an inevitable shortcoming?

foreach lv {3.6 3.7 3.8} {
    subport ${name}-${lv} {
        # snip
        post-patch {
            reinplace "s|@LLVM_INSTALL_PREFIX@|${prefix}/libexec/llvm-${lv}/lib|g" ${worksrcpath}/CMakeLists.txt
        }
    }
}
