title: Development for Acorn RISC OS on Raspberry PI
body: <p>Can anyone suggest or recommend development tools or documentation for writing graphical applications on the Acorn RISC OS on the Raspberry PI? This OS is newly supported on the Raspberry PI computer, and I would like to be able to write graphical applications for that OS. It is however quite hard to identify working tools for the version on PI, given the long history of RISC OS, the (multiple) incompatible revisions of the OS, and relatively scant resources for RISC OS on PI.</p>
  
  <p>One set of development tools bundled on the official RISC OS SD card image is the <a href="http://riscos-charm.yolasite.com/" rel="nofollow">Charm</a> high level programming language.</p>
  
  <p>There is an implementation of the <a href="http://www.wra1th.plus.com/lua/risclua.html" rel="nofollow">Lua</a> scripting language available too, with extensions to integrate with the WIMP GUI environment.</p>
