Arnold 16-Jun-2013 [8421x2] | That solved it! Thnx, now putting the questionmark back in. |
(As fast as yesterday) The base-1 versus base-0 would be accountable for a minute delay (less than 1% of the addressed numbers in the array, the 0-th and the last). The use of variables in the register looks more likely imho. Good point for the wishlist. | |
DocKimbel 16-Jun-2013 [8423x2] | I was going to add register variables to the Red/System V2 wish list. This is not required as one of the first change I have in mind for Red/System 2.0 is adding a good registers allocation method to backend code emitters. |
That change alone should make a significant difference in speed (I expected it close to twice faster) and code size compared to the current approach. | |
Arnold 16-Jun-2013 [8425] | Put it on for the world to know :) The mersenne twister has a lot of examples in other languages. finding out the closest 1 to red/system. |
PeterWood 16-Jun-2013 [8426x2] | Arnold as I understand, If the compiler to fully uses the registers then they wouldn't be available for application programmers. |
to fully -> fully | |
DocKimbel 16-Jun-2013 [8428] | I'm making good progress on the new Android bridge and demo, I should be able to release it tonight with all the new changes in source code (so Pekr will not need to reverse-engineer the apk ;-)). |
Pekr 16-Jun-2013 [8429] | most probbly I will do so anyway ;-) Will the demo be hello world example, or more usefull one, e.g. getting a contact list item? :-) |
DocKimbel 16-Jun-2013 [8430] | I'm not sure you're much interested in learning how to do it using Java objects, do you? It can be done already, but in order to implement proper abstraction for Red, we need at least objects support. Also, getting the GUI layer done is higher priority. |
Kaj 16-Jun-2013 [8431x2] | Arnold, sorry about forgetting the parentheses. They will really be gone in Red/System v2 :-) |
The register storage class in C is just an advice from the programmer to the compiler. The compiler always needs to make the best use of the available registers. Your variables may or may not be stored in them, and if you request them, you may or may not get them | |
Arnold 16-Jun-2013 [8433x2] | @Kaj, no problem, and Peter came to the rescue. Amazing even with a community this small, these things get solved in such a small timeframe. |
I cut out all register directives from the C source, replaced with ordinary declarations. Program is yet as fast as previously. Most likely to me is the XCode compiler fills in some optimisations regarding this. | |
Kaj 16-Jun-2013 [8435x3] | Yes |
When Knuth wrote it long ago, it probably still made some difference in some compilers then | |
It even has #defines for K&R declarations... | |
Arnold 16-Jun-2013 [8438] | About the pointer, I got the example of pointer/value: value somewhere, not saying from the fossil repository but might very well be so. The pointer: :value suggested confuses me. I tend to stick to what I had figured out. I prefer to avoid pointers almost always at all costs because of the trouble they can be. A good description is needed of how they are best used in Red(/System). |
DocKimbel 17-Jun-2013 [8439x3] | Arnold, if you have specific questions about pointers in Red/System, maybe you could ask them on SO and make the first SO entries for Red? |
Red on Android teaser: http://static.red-lang.org/droid-eval.png | |
Notice that this runs on the x86 emulator, there's still a few bugs to fix for the ARM version. | |
Henrik 17-Jun-2013 [8442] | Nice :-) |
DocKimbel 17-Jun-2013 [8443x3] | Also, it's possible to use a ICS skin...I just need to figure out how/where to define it. |
The whole UI is built in Red, calling the Android API through JNI. | |
Though, there's no UI dialect yet, but it can be built pretty quickly as Kaj demonstrated in the GTK binding. | |
Pekr 17-Jun-2013 [8446x2] | ah, looks nice anyway. So - was the bridge rewriten, wrt your mentioned jni object limit? |
What I mean is - would like to post something to FB channel, but not necessarily if the screenshot is an interim teaser. I can wait for some "more official" release, but surely I don't know your intentions, e.g. yesterday you mentioned objects, but those might be few weeks away? | |
DocKimbel 17-Jun-2013 [8448x2] | Rewrite bridge: that was my intention, but I gave up after hitting a few walls in Java reflective abilities. So, I just optimized the memory usage of the current one and improved it. |
Objects are required to build a cross-platform mobile API for Red. That way, you would use the same API for accessing universal mobile services and hardware from Red, like contacts, phone calls, SMS, GPS, Bluetooth,... | |
Pekr 17-Jun-2013 [8450x2] | ok, now I understand. So objects are next it seems? |
I mean - needed for parse, networking etc. anyway? | |
DocKimbel 17-Jun-2013 [8452x2] | In the meantime, you will only have a platform-specific API, but as soon as objects are done, we could add some nice abstraction layers on top of it. |
Yes, objects are becoming uber-urgent. :-) | |
Pekr 17-Jun-2013 [8454] | OK, so will ask in a different way (wrt Android) - will there be any official release, an example published, or even a blog article? If not, I will post as we go. If so, I might wait, so that we can refer ppl to download it and try to do their own small steps ... |
DocKimbel 17-Jun-2013 [8455x4] | Parse: not necessarily, it was just a requirement from Gab. |
Networking needs I/O, I/O needs ports, ports needs objects. :-) | |
If you mean by "official release" a 1.0, we're still far from that. | |
I might mention it briefly in the next blog entry. I would like to make merge the dyn-lib-emitter branch and make a new release. As the Java and Android bridges will be included, I will mention them. | |
Pekr 17-Jun-2013 [8459x2] | ok, any timing? I mean - since thursday I will be out for 4 days .... |
(there is no need to rush those things, I can wait) | |
DocKimbel 17-Jun-2013 [8461] | New release: Tuesday or Wednesday. |
Pekr 17-Jun-2013 [8462] | OK, good to know to plan ahead .... |
DocKimbel 17-Jun-2013 [8463] | Depends on how stable the ARM version of the bridge will be (and how much time I will take to fix it if required). |
Pekr 17-Jun-2013 [8464x2] | So I post a teaser, and later on will mention full new release, once the merge is in place and/or eventually blog article appears ... |
btw - is ELF emitter finished? Noticed Cyphre used some of Adrian's work for R3 droid port too ... | |
DocKimbel 17-Jun-2013 [8466x3] | I also plan to add a quick support for compiling kernel drivers for Windows. It shouldn't take long and some users need it, so I will give it a quick try. |
Post a teaser: go on with spreading the teaser! :) | |
ELF: no it's not, Andreas hasn't found time for it yet, but I can't wait anymore, so I'll merge it in master this week. | |
Kaj 17-Jun-2013 [8469x2] | Arnold, all sorts of constructs with pointers are valid, but the correction I gave is the correct translation of the C source |
pointer/value: value | |
