Anton 6-Oct-2006 [5716] | And note that it works also for sub-blocks: do bind [print [a]] context [a: 1] |
Pekr 6-Oct-2006 [5717] | I don't use bind, as it is more guru stuff, but is the bind as it is sufficient for you? e.g. wouldn't you prefer bind not binding for sub-blocks by default, and e.g. having bind/deep for such thing? |
Anton 6-Oct-2006 [5718] | Yes, I would prefer more options for binding particular parts of a block "surgically". |
Pekr 6-Oct-2006 [5719] | hehe, I can rebind whatever, even functions? do bind [print a] context [a: 1 print: :probe] |
Ladislav 6-Oct-2006 [5720] | yes, you can |
Pekr 6-Oct-2006 [5721] | hmm, but maybe mine is not example of binding anyway, it just simply created alias, no? |
Ladislav 6-Oct-2006 [5722] | I would prefer more options for binding particular parts of a block surgically"" - that is possible e.g. using my BUILD dialect or other instruments... |
Anton 6-Oct-2006 [5723x2] | It *is* an example. |
That's true, Ladislav, I was just about to write that it is possible to write higher-level functions. | |
Pekr 6-Oct-2006 [5725] | yes, it seems so ... print: :probe is known only in a newly created context, or so it seems ... |
Ladislav 6-Oct-2006 [5726] | right, Pekr |
Pekr 6-Oct-2006 [5727] | 'bind offers whole level of interesting low level (or high level, it depends how you look at it :-) magic ... |
Ladislav 6-Oct-2006 [5728] | right again |
Pekr 6-Oct-2006 [5729] | you can "borrow" your values here or there ... |
Ladislav 6-Oct-2006 [5730x2] | actually, you "borrow" variables, when using BIND |
(which is almost the same in many cases) | |
Pekr 6-Oct-2006 [5732] | and when such variable "points to" some other context, you get there too with newly binded word? Well, that is interesting also from security pov - we have powerfull instrument on one hand, but we have to be carefull on the other hand ... |
Ladislav 6-Oct-2006 [5733] | yes, that is why REBOL modules are hard to implement |
Pekr 6-Oct-2006 [5734] | one question - can we save and send some context, with all its bindings, to some other machine, load it there, and theoretically expect that such rebol got all identical environment? |
Ladislav 6-Oct-2006 [5735] | no |
Pekr 6-Oct-2006 [5736] | that could easily mean copying all internal state of particular rebol process, right? :-) I wonder is some language makes such a "reflectivity" (probably improper word) possible ... |
Anton 6-Oct-2006 [5737] | Of course, enter Jaime... |
Pekr 6-Oct-2006 [5738] | ah, so Scheme? |
Ladislav 6-Oct-2006 [5739x2] | Confusion for Pekr: f: func [x] [x] g: func [x] [x] var1: first second :f var2: first second :g bind second :f var2 bind second :g var1 f 1 g 2 f 3 g 4 |
what a mess, isn't it? | |
Pekr 6-Oct-2006 [5741] | yes, it is :-) |
Anton 6-Oct-2006 [5742] | Let me guess output: none, none, 1, 2 ? |
Ladislav 6-Oct-2006 [5743] | wrong |
Anton 6-Oct-2006 [5744] | Oops. |
Ladislav 6-Oct-2006 [5745] | #[unset!] 1 2 3 |
Anton 6-Oct-2006 [5746] | Ok makes sense. |
Pekr 6-Oct-2006 [5747] | fuctnion words remember their values? g 2 results in 1, which is there because there was first call to f 1 |
Anton 6-Oct-2006 [5748] | All words remember their values, unless you rebind the words to a different context. Whether a word is in a function body block or not doesn't matter. |
Ladislav 6-Oct-2006 [5749] | warning! according to the documentation it is possible that in the future REBOL function words will be set to #[none!] or something else when the function returns |
Henrik 8-Oct-2006 [5750x2] | Anyone have an idea on how INFORM stops the event system and returns to the console after pressing a button, allowing it to return a value? I've been studying the source of SHOW-POPUP, HIDE-POPUP, INFORM and the various POPFACE-FEEL objects, but I can't figure out how it's done. |
pressing a button = pressing a button in an INFORM | |
Gabriele 9-Oct-2006 [5752x2] | check the wake-event function |
basically, inform does a new wait [] | |
Anton 9-Oct-2006 [5754] | Starting at the top: system/view/event-port/awake ---> system/view/wake-event |
Gabriele 9-Oct-2006 [5755x2] | wake-event behaves differently when there is a popup open |
it returns true (which makes wait [] return) when hide-popup has been called | |
Anton 9-Oct-2006 [5757x2] | Yes, wake-event calls system/view/popface/feel |
inform calls show-popup which creates your new pop-face. | |
Rebolek 12-Oct-2006 [5759] | simple and almost useless tool :) do http://bolek.techno.cz/reb/webtext.r |
Anton 12-Oct-2006 [5760] | Hmm not bad. |
Gregg 12-Oct-2006 [5761] | Very cool bolek! With a few more fields for control of color and gradients, and the ability to save as an image, I would suggest it for inclusion as a Desktop entry with things like Font-lab and such. |
Rebolek 12-Oct-2006 [5762] | Good idea, Gregg, I'll look into it! Hm, guess I should finish Texture-lab also... :) |
Gregg 12-Oct-2006 [5763] | Yes! That was a way cool app. |
Rebolek 12-Oct-2006 [5764] | Updated version of TextureLab - do http://bolek.techno.cz/reb/texture-lab.r |
Louis 14-Oct-2006 [5765] | What could be causing this error. I get it whither I encap or not. ** Script Error: trans-date has no value ** Where: switch ** Near: forall args [ val: first args switch/default type?/word val [ pair! [append pairs val] integer... So far as I know I haven't touched this part of the script this is found in. |
