[!REBOL3] General discussion about REBOL 3
older newer | first last |
Andreas 19-Jan-2013 [750x2] | For one aspect. |
The module system could be a deciding feature pro R3. But we really need to get started on docs for that to become true. | |
BrianH 19-Jan-2013 [752x4] | The module system was almost complete in implementation with the last closed-source release, needing only the fixes we (and I mean me and you, Andreas) did in the first week of the open source release. We have only been waiting for Carl to add that pull request to get the current design working as intended, though that request doesn't only apply to modules in particular, but to scripts in general. Once it is accepted, I need to do another round of optimization, but the external effects are set already. |
So we are at the stage of writing docs and tests. | |
The only reason the user-level docs aren't yet written is because I am really bad at writing user-level docs of any kind. I was hoping that I could write some guru-level docs and then let someone read them and write something user-level. | |
As for that blog, the behavior described there has some practical problems. There is nothing in the code itself (I mean the example code in the blog, not the implementation code) to indicate that 'last-stock is a free variable, but 'if and 'not are not - they are all words not declared at the top level of the module (by using them as set-words, like in an object) or elsewhere in the code. This means that if you want it to have 'last-stock be made local to a module, you would have to make 'if and 'not local as well. That works if lib words can only be set once, but not if they can be reset, since changes wouldn't propagate to the other modules or user scripts (since those values are copied to words in other contexts). We determined that the behavior described in that blog could be useful enough to be worth supporting, but had some nasty side effects that made it not be what we wanted to do by default. That is why we made it an option, in particular the isolate option. If you specify the isolate option, your module acts like it does in the blog, and this has the effect of isolating your module from all external changes to the lib context. | |
GrahamC 19-Jan-2013 [756] | what isolate option? |
BrianH 19-Jan-2013 [757x7] | rebol [type: module options: [isolate]] your script |
Carl decided that the best way to make extensible options was to put the flag-like ones in an options block. That makes them extensible without bloating your header. | |
Another of the already-implemented options is private. The isolate option affects importing, the private option affects exporting. | |
You can do both of course. | |
There is also a content option (it acts like content: true from R2), and a compress option (for scripts that are stored compressed, and automatically decompress on load). | |
The content and compress options don't require type: module - they work on regular scripts too. | |
Scripts can also be checked against checksums, and can be limited to a length, but those aren't flags so they need their own header words. | |
Scot 19-Jan-2013 [764] | Great to know who the caretakers of R3 source are. Thanks for your work all six of you. :) |
PeterWood 19-Jan-2013 [765] | The six people named are caretakers of the R3 bug reporting system. At the moment, Carl is the only code caretaker. |
Ladislav 19-Jan-2013 [766x2] | Close, but not exact, I would say. Other people take care of r3 code as well. |
A picture is worth a thousand words: https://github.com/rebol/r3/network | |
BrianH 19-Jan-2013 [768x2] | Btw, "Reviewed" has generally meant that someone has gone over the ticket and not immediately found a good reason to dismiss it, and that we haven't found a problem yet. It is not an indication that the ticket should be implemented - we frequently have competing contradictory tickets. So it sometimes means that more debate is needed before we can accept or reject it. On the other hand, it sometimes means that we haven't gotten around to it yet. Nonetheless, some reviewed tickets will eventually be rejected. Carl and I were the reviewers for the most part, except in the case of bugs that needed some domain-specific knowledge, like the math bugs we referred to Ladislav. |
In general, when there are competing proposals and we finally pick and implement one, we dismiss the competing ones, even if they were "reviewed" before. | |
GrahamC 19-Jan-2013 [770] | do we have a state, awaiting implementation? |
BrianH 19-Jan-2013 [771] | Basically, "reviewed" with a consensus. No specific marker. We need to have the people who are familiar with the arguments go through the tickets that aren't still under debate and implement them. |
GrahamC 19-Jan-2013 [772x2] | Just that I had a proposal which was accepted and marked as built and then you reviewed and found it wasn't built |
So, how many of those are hanging around? | |
BrianH 19-Jan-2013 [774x2] | We might want to rethink that now that Carl and I aren't the only ones implementing things :) |
I haven't had a chance to go over the remaining tickets yet. And there are some that weren't implemented yet because Carl didn't want to, but hadn't yet convinced the rest of us as to why. Those might be dismissed if we get a good argument against them, which we can do in some cases ourselves now that we can see the native source. | |
GrahamC 19-Jan-2013 [776] | so we need a state of confirmed built |
BrianH 19-Jan-2013 [777x5] | That was the "tested" state. |
And we need to go through the old previously implemented but now invalid tickets, to mark them as such so we don't have bad tests added for them. | |
For some of the early tickets, more thought and experience caused us to change our minds later on. | |
We used the "tested" state for confirmed built. The "complete" state was supposed to be for when we added a test for it to the standard test suite, but we were not as consistent about that. | |
Graham, was that proposal state change recent? Was it changed to "pending"? We've had a bit of a definitional problem with the "built" state lately. Until we actually get official builds, with version numbers, we don't really have a defined "built" state. We need a state for "implemented and accepted as a pull request into Carl's repo, but not in an official build yet", but we've just been callung that "pending" for short. | |
Andreas 19-Jan-2013 [782] | I think using "built" to mark things once they get accepted is fine (much better than "pending"), but we then lack a state to describe things which have been submitted as pull request but have not yet been declined or accepted. |
Ladislav 19-Jan-2013 [783] | I updated http://www.rebol.net/wiki/Decimals-64 to reflect the current state of knowledge about molding and loading |
BrianH 19-Jan-2013 [784x2] | Yeah, we've been using comments for that. |
Andreas, maybe we can use "built" for accepted into the official repo, but have one of the "Fixed in" states for that, not giving it an actual version number in that field until it's in an official build. | |
Andreas 19-Jan-2013 [786] | yes, that's fine. but it won't give us a "waiting to be accepted" state :) |
BrianH 19-Jan-2013 [787x2] | And then we can use "pending" for waiting to be accepted. |
If you like, I can implement this policy this weekend. | |
Andreas 19-Jan-2013 [789] | We have only 8 "pending" tickets at the moment. |
BrianH 19-Jan-2013 [790] | It wouldn't take much :) And there might be miore tickets that should be in that state than are currently marked as such. |
Andreas 19-Jan-2013 [791x4] | So yes, I think using "pending" to mark "waiting to be accepted" is fine. |
No, I mean we have 8 tickets marked pending according to the "old" meaning. | |
So the policy change would not be very invasive. | |
Ah, those are seem to already be "accepted but not yet released" markes. So then that's an even stronger "yes" from me :) | |
BrianH 19-Jan-2013 [795x2] | For tickets with implementations that have been accepted into Carl's r3 master branch, mark the ticket with a Status of "built" and a Fixed in of "r3 master". |
For stuff that has a pull request that hasn't been accepted yet, we can use the "pending" status. Watch out though, since with that meaning of "pending" the ticket can now be dismissed at this stage (that didn't use to be the case with the old meaning of "pending"). | |
Scot 19-Jan-2013 [797] | Any insights on establishing .r3 file associations on Windows 7? Am I in the correct group for this? |
Ladislav 19-Jan-2013 [798x2] | You may want to have a look at http://www.rebol.net/wiki/INCLUDE_documentation#How_to_add_a_new_association_for_.r_files_in_Windows_Vista.2C_Windows_7_or_Windows_8 |
(more complicated than for the older Win versions, I admit) | |
