Universal Installer

Don't you just love it when you end up making work for yourself, right when you think you're overworked enough as it is?

Well, such a scenario just happened to me whilst getting ROTunes v0.08 ready for release. It suddenly occurred to me that I've made so many changes and improvements to the code, it's probably easier for anyone upgrading just to delete their existing copy and install the new version afresh! Of course, that's 'just not cricket', apart from being against the whole RISC OS philosophy of being flexible enough to cater for all levels of user as well as being considerate to the end-users preferences and time.

Therefore, there was no solution other than to write an installer application for the new ROTunes update. This would ensure that new users would end up with a nice new install but also allow existing users to upgrade without having to reset or lose all their choices and preferences etc.

This brought me to thinking that I've actually been striving to come up with a nice and simple way of supplying upgrades to my software for a couple of years now. I've half-written (or bodged) installers in the past, even attempting to write a kind of multi-purpose installer, but everytime I end up with something that's only really suitable for the task in hand and not ideal for re-using the next time I release another upgrade to something!

So..... this morning I decided that I was going to crack it once and for all, and write a completely generic, easy-to-use, universal installer application for any software I may decide to upgrade in the future. As Apple always seems to have well thought out installers and user interfaces, I thought I'd write something along similar lines - but of course make it smaller, leaner and better! happy

Thus, the completion of Paul's Universal Application Installer about 30 minutes ago (not bad going if I do say so myself - a new application from concept, design, planning and coding right through to finished, debugged release-ready version in under a day!)

I just need to finish bug testing ROTunes v0.08 and I can unleash both update and installer on the world! grin

Obliteration is precisely ugg boots cardy sale what nasa intends for the spacecraft. The reason is that Galileo may still harbor some ugg classic cardy boots signs of life on Earth: microorganisms that have survived since its launch from the Kennedy Space uggs bailey button uk Center, in Florida, in 1989. If the orbiter were left to circle Jupiter after running out of bailey button uggs chocolate propellant (barring an intervention, this would likely happen within a year), it might eventually crash into Europa, one of Jupiter's large moons. In 1996, Galileo conducted the first of eight close flybys of Europa, producing breathtaking sale bailey button ugg boots pictures of its surface, which suggested that the moon has an immense ocean hidden ugg usa bailey button beneath its frozen crust. These images have led to vociferous scientific debate about the prospects for uggs boots life there; as a result, nasa officials decided that it was necessary to avoid the possibility of seeding Europa with alien cheap argyle uggs life-forms. And so the craft has been programmed to commit suicide, guaranteeing a fiery, spectacular end to one of the most ambitious, tortured, and revelatory missions in the history of uggs classic mini space exploration.
