Ashley 11-Jun-2007 [8287] | A key consideration is whether you want the translation(s) to be static (compile-time) or dynamic (run-time). Advantages and disadvantages to both approaches. |
btiffin 11-Jun-2007 [8288] | Yeah, I toggle back and forth, but they'll be static this time. :) |
Rebolek 11-Jun-2007 [8289] | some BIND expert, please, help me: >> act: [add a b] == [add a b] >> for a 1 5 1 [for b 1 5 1 [do act]] ** Script Error: a has no value ** Where: do-body ** Near: add a b There must be something easier than >> for a 1 5 1 [for b 1 5 1 [do bind bind act 'a 'b]] |
Sunanda 11-Jun-2007 [8290] | Is this simpler and the same effect? act: func [a b][add a b] for a 1 5 1 [for b 1 5 1 [act a b]] |
Rebolek 11-Jun-2007 [8291] | hm, not exactly what I want because this is simplified, I have more variables than just 'a and 'b, but still useful. |
btiffin 11-Jun-2007 [8292] | May or may not work for your needs for a 1 5 1 [for b 1 5 1 bind act 'a] |
Graham 11-Jun-2007 [8293] | Is there an async https protocol in the offing? |
Gabriele 11-Jun-2007 [8294] | mine works with both http and https |
Graham 11-Jun-2007 [8295x2] | is this the current release? |
or you own unreleased version? | |
Gabriele 11-Jun-2007 [8297] | same version as used on the detective and published on my site |
Graham 11-Jun-2007 [8298] | Ok. |
Oldes 12-Jun-2007 [8299x3] | what would be the best way how to legalize urls like this one http://maps.google.com/mapfiles//cb/blue_outlines.png |
I mean rebol-file from such a url | |
hm.. parse t: "a//bb/c" [any [to "/" p1: some "/" p2: (p1: change/part p1 "/" p2) :p1] to end] t | |
Anton 13-Jun-2007 [8302x2] | You mean, to "clean" it, into a legal url ? |
http://anton.wildit.net.au/rebol/freezer/simple-clean-path.r | |
Oldes 13-Jun-2007 [8304x2] | yes... that's what I wanted.. especially to make the local file secure as well... (so converting url to local file does not leave the send-box:) |
I already had own version, but your is a little bit better as correctly handles complete url... my was only for the path | |
Chris 13-Jun-2007 [8306] | This is one reason I wrote my files:// protocol -- http://www.ross-gill.com/r/sandbox.html (need to add to the library). |
Anton 14-Jun-2007 [8307x2] | we also had a secure-clean-path.... |
Ah.. secure-clean-path should be in rebol.org already. | |
Henrik 16-Jun-2007 [8309x4] | do func [a b /c] [either c [a + b][a * b]] 2 3 How do I invoke the refinement? |
or perhaps: f. func [a b /c] [either c [a + b][a * b]] 2 3 do :f 2 3 ; <--- here? | |
Think I figured it out... | |
nope, didn't work. I need the function in a composed block: compose [do (:f/c) 2 3] ; causes error, since arguments are not inside the compose parantheses. But the arguments are not used, so: compose [do (:f/c 2 3)] But now the arguments are local to the function. The arguments come from a different context, so I can't just compose the get-word'ed function with the arguments. So I'll go back to the first question on how to make a refinement on an inline function? | |
Graham 16-Jun-2007 [8313] | why use the refinement in a throwaway function? |
Henrik 16-Jun-2007 [8314x3] | the function is rather complex and must be used many times, so I wrote it outside the block. |
the block is a database query on a remote machine | |
and the function helps me to find out whether certain conditions for a database entry is true or false | |
Graham 16-Jun-2007 [8317] | Didn't Maarten use refinements in rugby? |
Gabriele 16-Jun-2007 [8318x3] | hmm, since you're composing, why not put a path there? |
otherwise... do 'f/c 2 3 should work. | |
>> f: func [a b /c] [either c [a + b][a * b]] >> do 'f/c 2 3 == 5 >> do 'f 2 3 == 6 | |
Henrik 16-Jun-2007 [8321] | gabriele, what if the function is local, but must be used remotely (security is unimportant right now) |
Anton 16-Jun-2007 [8322] | That is a good question, Henrik. |
Volker 16-Jun-2007 [8323x3] | what is wrong with an extra assignment? f: func [a b /c] [either c [a + b][a * b]]] f/c 1 2 |
do (f: func [a b /c] [either c [a + b][a * b]] 'f/c) 2 3 | |
or a wrapper, an 'f-without-c and 'f-with-c. | |
Henrik 16-Jun-2007 [8326] | volker, can't check right now if that works, but does it pack the entire function inside the block? |
Volker 16-Jun-2007 [8327x4] | inside the parens |
and then returns a path with a refinement. 'do gets the path, done. | |
You can put a 'use around it to avoid the temp | |
But not really sure what you want to do. somehow sending a function i guess. | |
Gabriele 18-Jun-2007 [8331x2] | well... if it's to be automatically called etc., i'd suggest avoiding refinements as much as possible. just use a logic arg. |
if you really have to use refinements, you have to compose a path, no other way around in r2. (you see, that's why we've been asking for a low level apply native for so much time) | |
Henrik 18-Jun-2007 [8333] | I see, thanks |
Terry 18-Jun-2007 [8334] | After dealing with strings for so many years with various languages, I would say that TRIM should be default with any reading/writing functions, and when you don't want something trimmed then use a function. a: " my untrimmed string " write no-trim a |
Anton 18-Jun-2007 [8335] | That doesn't make any sense to me as I hardly ever use trim. In the case where TRIM is embedded into some functionality, disabling it becomes an exercise of varying difficulty. eg. VID's TEXT style trims text automatically, unless you specify AS-IS. Discovering where this happens takes a little while. |
Maxim 18-Jun-2007 [8336] | I second Anton's statement... adding TRIM is EXTREMELY damaging to data. 100% of work I have done in the last year implementing transactional ticketing web services 100% implemented in REBOL would have been simply nightmarish if such data destruction would have occured. |
