RISC OS User Group Of London
ROUGOL is a not-for-profit organisation consisting of RISC OS users in London and the south-east. Our aim is to bring those users together. There is no membership fee and entry to all meetings is free. To find out more, email us.
Meetings are held on the third Monday of every month. Most meetings feature a guest speaker, demonstrating the latest hardware or software, giving tutorials of software both new and old, or simply to kick off discussions on the current hot topic. Entrance is free, so why not come along and say hello?
The next RISC OS London Show is on Saturday 29th October 2016.

Lua and Dynamic Linking on RISC OS - Gavin Wraith
Lua is a small easily learnt programming language that has been available on RISC OS, in the form of RiscLua, since 2002. Only now, though, with the arrival of GCC 4.7.4, has it become possible to implement Lua on RISC OS in anything like its standard form as found on other platforms.
The recently released RiscLua 6.0 attempts to be such an implementation and also to be as compatible as possible with earlier versions.
The big new feature is that it can use dynamic loading. Whereas programs running under previous versions of RiscLua could only extend themselves by loading in Lua libraries, now programs can extend the Lua interpreter itself, as they are being interpreted, with C libraries. This makes RiscLua far more extensible than it was before, when everything had to be linked statically. The difference between Lua modules and C modules is invisible to the user.
Gavin Wraith, the developer of RiscLua, will tell us about the possibilities this opens up and
why it is a significant advance for RISC OS.
