Pekr 1-Mar-2013 [5619] | Doc - that's interesting questions indeed. What attracted ppl to Rebol, was, that it was a complete package. So no problem with tonnes of libraries out there, plus wrappers, but curious to know, if you still think, that some common standard would be nice to have ... well, it would be even better to have ports for many things, plus schemes, plus codecs below :-) |
DocKimbel 1-Mar-2013 [5620x2] | common standard for what precisely? |
What attracted ppl to Rebol, was, that it was a complete package Who said that Red will not be a complete package too?? | |
Bo 1-Mar-2013 [5622] | @Pekr: That's one of the things that attracted me to Rebol. I didn't like to have to specify every library file that I wanted to link to and have all these dependencies...just one package with everything in it. |
Pekr 1-Mar-2013 [5623x2] | for many things we are used to ... so that Red is able to read bmp.jpg png, play basic sound, do compression/decompression .... |
well, Bo, explained it better. I am not saying that you are not planning it, I was just asking, if it is planned, because other point of view might be, that we will get some very core funcionality, plus millions of nice wrappers, but that would make a different feeling ... | |
Bo 1-Mar-2013 [5625] | Or at least like the Rebol SDK where you can easily include the major components you want, and the granularity to remove ones you don't want, like the View subset. |
DocKimbel 1-Mar-2013 [5626] | For Red, it will rather work as R2 SDK where you just import the modules you need to build your binary. We would also provide a console binary with all or most of modules included by default (like the fat binaries from the SDK). |
Bo 1-Mar-2013 [5627] | I like the way the R2 SDK worked. You could include a whole subgroup of functionality or just component-by-component. |
Kaj 1-Mar-2013 [5628x3] | As we discussed before, you can get JPEG data from the GDK binding, but you have to finish the struct definition |
Any framework that supports more than one image format will have its own internal format. That goes for R2, SDL, GDK, ImageMagick and any other framework you could bind to | |
If you bind to LibJPEG directly, you'll have to devise your own internal format once you add support for another image type | |
Bo 1-Mar-2013 [5631] | @Kaj: I'm trying to get the JPG data without having X11 installed. If I were to do something with LibJPEG directly, I would try to make it look like the R3 image! datatype. |
Kaj 1-Mar-2013 [5632x2] | Are you sure GDK has a dependency on X? |
Looks like it | |
Bo 1-Mar-2013 [5634] | I was pretty sure GDK required X. |
Kaj 1-Mar-2013 [5635x4] | Yeah, I checked and I'm not sure, but it's very entangled |
You could compile GDK on DirectFB instead of X, but it would be a lot of work | |
You could make a binding with SDL-Image to have fewer dependencies | |
A binding with DirectFB or Enlightenment just for the images would also be less massive | |
Bo 1-Mar-2013 [5639x2] | Thanks for those ideas, Kaj! I'm thinking it may be better just to wrap libjpeg. |
I don't have a lot of experience with C and library bindings, but I've done a bit and I can give it a shot when I have a bit of time. | |
Bo 2-Mar-2013 [5641x2] | Sometimes, I'm such a dunce! Something Kaj said in the past hit me as I lay awake in bed at 4:45am this morning. IIRC, he said that Red/System could be used to extend R3. My problem is that I need to perform some advanced processing on jpg images. I wanted to do this natively in Red/System, but had issues getting the jpgs loaded into bitmap form. R3 can already load jpgs into bitmap form, so why not call a Red/System compiled executable to do the processing? |
Thanks so much, Doc, for making R3 easy to extend using a Rebol-like compiled language! Thanks so much, Kaj, for your insight and foresight! | |
Kaj 2-Mar-2013 [5643x4] | If that's your purpose, then yes, that would be a nice combo |
Just this week I checked that the Red-R3 bridge works with the updated dyn-lib-emitter branch of Red | |
There are still various bugs in R3, though. You seem to need the latest build from Andreas, and R3 corrupts tuples passed across the bridge | |
On the other hand, weren't you doing this on Raspberry Pi? The Red dyn-lib-emitter branch and thus the bridge are currently only available for Windows | |
Bo 2-Mar-2013 [5647] | That will be a problem. Maybe I'll have to pass the data using slower semaphores. |
DocKimbel 2-Mar-2013 [5648x3] | Function building and evaluation now supported by the interpreter. Here's how it looks like from the Red console: red>> foo: func [a b][a * b] == func [a b][a * b] red>> foo 3 4 == 12 |
The interpreter (DO) is much more capable than the current console with its currently limited tokenizer (LOAD). So, e.g., the interpreter fully supports paths and refinements while the console don't. | |
Nobody has proposed me so far to build a R2-level cross-platform console for Red, so I will implement one in the next weeks. Before that, I will probably work on PIC support for Mach-O and ELF and implement object! support. | |
Kaj 2-Mar-2013 [5651] | Exciting! |
Gregg 2-Mar-2013 [5652] | That's great Doc! |
Kaj 2-Mar-2013 [5653] | Bo, you could use the 0MQ bindings to pass the images between Red and R3 |
Bo 3-Mar-2013 [5654] | I've never really looked into 0MQ, but I know you did some binding work with that. |
Arnold 3-Mar-2013 [5655x4] | Sorry Doc, it is hard to get-and-keep up to what you all achieve!! (And Kaj too) Even though I myself have less hours at my job I do not have as much time to follow it all. (More projects and chores in and about the house to do now and less 'spare' time at work for a quick review. |
I will try to answer the question of how I see possibilities to make Red more suitable for funding. And have it get the attention a first proper release needs. Everybody else is hereby invited to think along how to make this possible. | |
What I see as a first possible step is have a kind of Red website hosting where websites can be hosted using Red (cheyenne server) and a database behind it (MySQL or SQLite) and a possibility for digital payments (such a module could be additionally payed and kept 'closed' source). This could obviously generate a modest cashflow. There would be needed books etc. | |
time is up now sorry. | |
Kaj 3-Mar-2013 [5659x3] | I'm happy to report that Red works well on stock Windows 2000 |
Even most of the bindings work, except GTK and 0MQ, because their libraries are not compatible with 2000 | |
Perhaps it could be helped by installing newer versions of the Windows C library | |
DocKimbel 3-Mar-2013 [5662x2] | Arnold: finding good ideas for new revenue streams to fund Red would be indeed helpful. |
Kaj: interesting finding, but no that surprizing as the interfacing of Red with Windows API is currently quite limited. | |
Kaj 3-Mar-2013 [5664x2] | I need that setup to test, and I may need it to compile binding libraries myself |
0MQ also doesn't work on XP, so that's more surprising and problematic | |
Gregg 3-Mar-2013 [5666x2] | The 0MQ issue may be with newer bulids. I used old versions on XP just fine. |
Not from Red of course. | |
Fork 4-Mar-2013 [5668] | Beating the test suite alone is perhaps an unwise quest, so here is an as-is state of the Red port for people to tinker with and look at. https://github.com/dockimbel/Red/pull/421 |
