Maxim 8-Jan-2013 [5212] | its dangerous because issues are very often used for hexadecimal notation. this will complexify things for dialectors. if the above is implemented, an any-issue! type must be added to allow comparing both forms as the same type, when it doesn't matter. overall, not sure the added confusion is really worth it. |
Ladislav 8-Jan-2013 [5213] | yes, you summed up the issues, Max |
Kaj 8-Jan-2013 [5214x3] | Red has a dedicated notation for hexadecimal numbers |
If you know it's a number, you shouldn't use a string issue for storage: that's wildly inefficient | |
With my proposal, you can parse numbers in issue notation, detect it's an integer and convert it to integer storage, without polluting the symbol table | |
Maxim 8-Jan-2013 [5217] | Kaj, you're missing the point, in real life, the idea adds confusion to dialecting and probably very little benefits in real-life. very few uses require *only* first characters as numbers IMHO. most will also use other chars as part of their dataset. |
Kaj 8-Jan-2013 [5218] | There definitely is a point. Please read the above discussion |
DocKimbel 8-Jan-2013 [5219] | Another thing: are natives more efficient than routines? Routines and natives are both Red/System code that use Red runtime internal API, so they perform the same. In case of routines, you might have a tiny overhead for integer! and logic! that are converted back and forth between Red and Red/System, but it is really very small, and only significant if you iterate a lot of times over a routine call. From the memory and boot time perspective, natives are more efficient because their body block is not stored internally for reflection like routines. So, for functions like QUIT that should be part of Red core, it is better to implement them as natives, to save memory and booting time. |
Arnold 8-Jan-2013 [5220] | Until SMS texting there were very little words spelled with numbers in them. |
Kaj 8-Jan-2013 [5221x2] | Doc, thanks for the explanation. About reflection, will there be a compile option to turn it off, for commercial code that should stay closed? |
It may also be useful to turn it off per function, for example for being able to write routines almost as efficient as natives | |
Bo 8-Jan-2013 [5223x2] | Sorry to change topic from the current issues (pun intended), but I wanted to say thanks to Doc and Kaj for the information about graphics on Red/System on Linux running on ARM! Where could I download the GTK.reds file? |
Sorry if the answer is obvious and I just missed reading it somewhere. | |
Kaj 8-Jan-2013 [5225x2] | http://www.red-lang.org/p/contributions_20.html |
You also need the Red-GLib and Red-common repositories which aren't listed there | |
Bo 8-Jan-2013 [5227] | Where would I find those? |
Kaj 8-Jan-2013 [5228] | In the same place, using the same name pattern |
DocKimbel 9-Jan-2013 [5229x2] | About reflection, will there be a compile option to turn it off, for commercial code that should stay closed? What I planned so far is a compile option to switch between different modes of bundling the functions/routines source code into the final executable. Main options are: - in form of native "build instructions" (the current behavior) - in form of compressed text The latter option will generate smaller executables, but will be slow down boot time a little, as it will require the interpreter to process it. The former option provides a high level of obfuscation, that requires a lot of work to decompile (cracking REBOL's SDK protection is probably an easier job). |
interpreter => tokenizer | |
Kaj 9-Jan-2013 [5231] | Hm, I guess interpreted functions make it hard to leave out the source in some form. That would be another argument for being able to designate it per function |
DocKimbel 9-Jan-2013 [5232] | Actually, every statically defined Red function will get compiled, only functions created at runtime will be passed to the interprerter (or JIT-compiled). |
Kaj 9-Jan-2013 [5233] | Yes, but the source is still included for reflection, isn't it? That could be removed |
DocKimbel 9-Jan-2013 [5234x2] | So the "interpreted functions" do not exists at compile-time nor in the executable in source form, as their are created at runtime. |
they | |
Pekr 9-Jan-2013 [5236] | what about function argument, like in Rebol? I mean, those catch etc. arguments? |
Kaj 9-Jan-2013 [5237] | I thought the source is added as extra for body-of? |
DocKimbel 9-Jan-2013 [5238] | We could remove the body block of compiled function! values, yes, so it doesn't get added to the executable. That could be an optional switch that would also disable undefine 'body-of accessor. |
Kaj 9-Jan-2013 [5239] | Yes, that's exactly what I mean |
DocKimbel 9-Jan-2013 [5240] | Pekr: I don't understand your question, could you be more specific? |
Pekr 9-Jan-2013 [5241] | Doc - Kaj wants some option to trigger functions being complied in various ways. I just said, that maybe it can be done on per function basis, using special parameters ... my-func: func [[dynamic] a [integer!]][] |
Kaj 9-Jan-2013 [5242] | Yes, I was also thinking in that direction |
Pekr 9-Jan-2013 [5243] | The problem might be, that it has to be decided during compile time, so the source code would have to be analyzed. Otoh it might be the right place (instead of preprocessor) to fit in, along with catch, throw .... |
DocKimbel 9-Jan-2013 [5244x6] | You can still define it at runtime in such case, instead of statically define it. No need to add another attribute. |
Functions created at runtime will always retain their body block. | |
You will be able to achieve that using different approaches: 1) Using DO: do [foo: func [...][...]] 2) Indirectly specifying the spec and/or body block: body: [...] foo: func [...] body | |
This will result in 'foo function been created at runtime (then JIT-compiled or interpreted on each call). | |
Kaj: you should add your syntax proposition for keyword! + issue! to github tracker as a wish, so we don't forget about it. | |
If we don't find any big drawback, I think I will implement it. | |
Kaj 9-Jan-2013 [5250] | OK, thanks |
DocKimbel 11-Jan-2013 [5251] | Added routines invocation support to interpreter. |
Pierre 11-Jan-2013 [5252] | Congratulations: the rhythm of changes in Red is just fast! I scripted a little command that I run from time to time, just to see how both Rebol3 and Red are going: cd ~/dev/Red/ && git pull && cd && cd dev/r3/ && git pull And I can see through gitk that the rythm of Red's work is just amazing. Courage! |
DocKimbel 11-Jan-2013 [5253] | Merci Pierre ! :-) |
Pierre 11-Jan-2013 [5254] | De rien, merci à toi! I cannot really find a startup guide for Red: so, if no one shouts, I'll try to write one, during my long hours of flight next week. |
Kaj 11-Jan-2013 [5255] | That would be good |
Pierre 11-Jan-2013 [5256] | ok, then! |
DocKimbel 11-Jan-2013 [5257x3] | Pierre, have you scrolled down throw this page: https://github.com/dockimbel/Red ? |
through | |
Let me know if there are missing information there. | |
Pierre 11-Jan-2013 [5260] | I had read another version of these instructions; it looks like it was reworked a bit. |
DocKimbel 11-Jan-2013 [5261] | Yes it was, the Red/System README was merged in Red's one. |
