Kaj 29-May-2013 [8058x4] | My multi-line implementation is here in console.red. It's fairly complete; not sure if you have more: |
http://red.esperconsultancy.nl/Red-common/dir?ci=tip&name=examples | |
No GC in Red yet, though :-( | |
The viking ship is how I always thought about it :-) | |
Geomol 29-May-2013 [8062x2] | The license for Red at bottom of https://github.com/dockimbel/Red/blob/master/README.md state, that the runtime uses the more permissive BSL license. Why this distinction? |
:) Yeah, us crazy vikings. | |
Kaj 29-May-2013 [8064] | Because Red needs to compete with other compilers. Classic compilers insert only very small pieces of boilerplate code, so that's free of rights. Red inserts the entire runtime and interpreter in compiled programs, but it needs to compete with that freedom |
Geomol 29-May-2013 [8065] | And Red owner could get into trouble, if not giving permission or what? |
Kaj 29-May-2013 [8066] | No, but people would complain that when they keep programming in C++, their executables are more free |
Geomol 29-May-2013 [8067] | Licenses kinda sucks, don't they? When Mozart visited the sixtin chapel in Rome in 1770, he heard a secret piece of music, Allegris "Miserere". From memory, he wrote the piece down with all 12 voices or how many, when he was back at the hotel. Later he received an order from the Pope. Licenses kinda remind me of this. Why show or play something for someone else, and then at the same time say, you can't use it? :) |
Kaj 29-May-2013 [8068x2] | Yeah, it complicates things a lot |
So far I have mostly talked about the ability to write R3 extensions in Red and Red/System, because I made a specific bridge for that. But with Red's ability to generate shared libraries, you can also make generic extensions for other systems, such as R2 and World. You can write libraries in Red and then import them with the DLL interfaces in World and R2 | |
Geomol 29-May-2013 [8070x2] | nice |
If you see any code from me, be it mezzanines or C source or anything, use it, if you can! And I don't ask for specific mention. If people feel, they got some pieces of gold and wants to mention, where they got it from, fine. | |
Kaj 29-May-2013 [8072x2] | Thanks, that's great! |
But a viking deserves a rune stone in his memory, don't you think? | |
Geomol 29-May-2013 [8074x3] | :) I'll create my own rune stones. (Any someone may create one too, but I don't ask for it.) |
*And* | |
I got the red-core interpreter running here btw. That was easy. But I miss a HELP function in there. And I see a lot of functions, so it seems to have come quite a way, but no DO of scripts? | |
Kaj 29-May-2013 [8077x3] | Gregg is working on HELP and WHAT, but it seems to have stalled |
I/O is not in Red, only in my extensions. DO is the internal interpreter, so it doesn't know about my I/O. It's a good point, I should try to override DO | |
You can start a script when you give its name on the command line, even a URL | |
Geomol 29-May-2013 [8080x2] | I think, it would be a lot easier for e.g. Gregg to create mezzanines, if he could do a script with them, like cortex.w and rebol.w in World. |
ok | |
Kaj 29-May-2013 [8082] | Yes, I'll look into it |
Geomol 29-May-2013 [8083] | How are Red scripts named? .r or .red or what? |
Kaj 29-May-2013 [8084x4] | .red but it doesn't really matter |
Note that, even if DO and LOAD currently don't work on files, you can still use: | |
DO READ %file | |
DO READ "url" | |
Geomol 29-May-2013 [8088] | ok, good enough for now, I guess. |
Gregg 29-May-2013 [8089] | Red HELP func made some decent progress, but I stopped work on it because of some issues, and I didn't want to distract Doc until he's done with Android. |
Geomol 29-May-2013 [8090] | I looked at REBOL WHAT function, Kaj mentioned. I don't think, I've ever used it. Is it commonly used by you guys? |
Gregg 29-May-2013 [8091x4] | Almost never for me. |
BTW, my Red HELP experiment is here, under %Red/mezz/. You can paste it into a Red console to test. | |
Ah, yes. One issue was that calling HELP with no arg crashes the interpreter. | |
I might have stopped until we have errors in Red, because debugging by crashing is hard. ;-) | |
Geomol 29-May-2013 [8095] | yeah :) |
Gregg 29-May-2013 [8096] | But also shows that you can still do a lot in Red, even without it. Most of the mezz code I did works. |
Kaj 29-May-2013 [8097] | WHAT is quite essential on Try REBOL for new users |
Gregg 29-May-2013 [8098] | It's never struck me as a great name. I just always use HELP. e.g. HELP function! |
Kaj 29-May-2013 [8099x3] | It's very introductory, like What, Why, When, Where. You need that before you know to do HELP function! |
I found a bug in the interpreter that currently prevents me from overriding DO: | |
https://github.com/dockimbel/Red/issues/482 | |
Gregg 29-May-2013 [8102] | Except, we don't have WHY, WHEN, or WHERE. ;-) |
Geomol 29-May-2013 [8103] | World should have a WHY??? :) |
Kaj 29-May-2013 [8104x2] | I don't see how that devalues WHAT. :-) And R3 has WHY? |
I don't remember which, but I think there are old computer systems that list available commands with WHAT | |
Arnold 30-May-2013 [8106] | WHAT is to find out what stuff is attached under an object. I use (d) it a lot with VID, finding out which field was filled with what value to see how I could go about dynamically change the properties like captions and values and colors. |
Geomol 30-May-2013 [8107] | Arnold, isn't that what HELP (or the ? short) is used for? WHAT seems to "Prints a list of globally-defined functions.". |
