0runner

A simple multi-launcher for 0install

The maintainer of ZeroInstall has a philosophical objection to allowing the direct expression in feed files of package build instructions with multiple steps. To get around this inconvenience, 0runner can be used to 0launch a sequence of feeds, passing ; as a separator between lists of arguments to be passed to 0launch. For example, the following snippet issues two cmake commands in sequence:

<command name='compile'>
 <runner interface='http://ryppl.github.com/feeds/ryppl/0runner.xml'/>
   <arg>http://afb.users.sourceforge.net/zero-install/interfaces/cmake.xml</arg>
       <arg>-D</arg> <arg>CMAKE_INSTALL_PREFIX=${DISTDIR}</arg> <arg>${SRCDIR}</arg>
   <arg>;</arg>
   <arg>http://afb.users.sourceforge.net/zero-install/interfaces/cmake.xml</arg>
       <arg>--build</arg> <arg>.</arg> <arg>--target</arg> <arg>install</arg>
 </runner>
</command>
