[REBOL] refinements Re:
> I want to pass all of the given refinements to another function.
There's a better way of doing this. Just 'append (you have to replace
'append with a better 'append, though) the refinements of the function to
the function as a path.
Like this:
; A replacement 'append function that doesn't evaluate 'series and uses a
refined path for 'insert.
append: function [
{Appends a value to the tail of a series and returns the series head.}
series [series! port!]
value
/only {Appends a block value into a block series as a block}
][
Refined_Insert
][
Refined_Insert: to path! 'insert
if only [head insert tail :Refined_Insert 'only]
head Refined_Insert tail :series :value
]
And this function shows how to use it:
SNA_switch: function [
"Selects a choice and evaluates what follows it."
value "Value to search for."
cases [block!] "Block of cases to search."
/case "Value is case-sensitive."
/only "Treats a series value as a single value."
/any "Enables the * and ? wildcards."
/default Default_Case "Default case if no others are found."
][
Refined_Select
][
Refined_Select: to path! 'select
if case [head insert tail :Refined_Select 'case]
if only [head insert tail :Refined_Select 'only]
if any [head insert tail :Refined_Select 'any]
either found? value: Refined_Select cases value [
do value
][
either default [
do Default_Case
][
none
]
]
]
I hope that helps!

[REBOL] refinements Re:
Hi Michael, here's another idea: 1. Use refine-func instead of func to create a function. 2. Use call-with-refine to call a function with refinements. Example: Given the function f: f: func [/a /b /c][if a [print 'a] if b [print 'b] if c [print 'c]] You can create a calling function g: g: refine-func [/a /b /c] [ call-with-refine f refinements ] Such that: >> g == false >> g/a a == false >> g/b b == false >> g/c c == false Here are the two functions refine-func and call-with-refine: refine-func: func [spec body /local refinements] [ refinements: make block! length? spec foreach word spec [ if all [ refinement? word word <> /local ] [ append refinements to word! word ] ] insert body compose/deep [ refinements: make block! 0 foreach word [(refinements)] [ if get :word [ append refinements word ] ] ] either found? find spec /local [ append spec 'refinements ][ append spec [/local refinements] ] return func spec body ] call-with-refine: func [:f ref-block [block!] /local g] [ g: make path! compose [f (ref-block)] g ] Oh, by the way, the function defined as g: refine-func [/a /b /c] [ call-with-refine f refinements ] ends up looking like this: >> source g g: func [/a /b /c /local refinements][ refinements: make block! 0 foreach word [a b c] [ if get :word [append refinements word]] call-with-refine f refinements] >> At 12:50 PM 5/24/00 -0700, you wrote: >A while back a message was posted to the list (can't find it now) about >wanting to loop on the refinements specified to a function, without an 'if >for each one.

[REBOL] refinements
A while back a message was posted to the list (can't find it now) about wanting to loop on the refinements specified to a function, without an 'if for each one. I've finally come up with a reason to do something similar: I want to pass all of the given refinements to another function. That is: - I call func A, giving some refinements - func A calls func B with all of the refinements given to func A I have been doing the 'if thing on each possible refinent of A and performing a different (hard-coded) call of B with each different refinement, but this would get messy if I were to specify more than one refinement at a time. I have found an "automatic" way of building the funcname/refinement string, but I haven't found any "slick" way of doing it. BTW the code below could be improved by recognizing only refinement! from the first func block. However, I haven't decided whether I even want to use it. f1: function [/a /b /c][local1 local2 local3][ ; Calls function F2 with the refinements given to this function ; MUST define [local1 local2 local3] (exactly) as locals to this function local3: :f1 do bind refine 'local1 do join "f2" local1 ] f2: func [/a /b /c][if a [print "a"] if b [print "b"] if c [print "c"]] ; Then, somewhere in the code specify the block: refine: [ local1: make string! length? first :local3 ; Assume that no other parameters were specified repeat local2 length? first :local3 [ if true = get bind to-word pick first :local3 local2 'local1 [append local1 join "/" pick first :local3 local2] ] ] ; Example use: >> f1/b b == none >> f1/b/c b c - Michael Jelinek

[REBOL] [REBOL]hidden variables in objects? Re:
Hi Tim, hiding words in REBOL is independent of objects and facilitated by the 'use context. The 'use context can be used in objects. The 'use native is used to create a context in which words are hidden: use [ a b c ] [ a: 1 b: 2 c: 3 ] object: make object! [ a: none b: none use [a b] [ a: "this is the hidden a" b: "this is the hidden b" ] ] If we probe the object we find that the words in the use context are not exposed: >> probe object make object! [ a: none b: none ] At 09:20 AM 5/24/00 -0800, you wrote: >I am presently reviewing a presentation on rebol >made by a third party.

It is a great tag for returning results from multiple queries, by shifting the calling of the queries off the server and onto the client. Cheers, Allen K
[REBOL] Simple CGI Problem Re:(8)
Another solution is to return an image of the number rather than the text. There is a script on rebol.org that can create these number gifs on the fly. So adapt it to your counter needs. http://www.rebol.org/cgi/gif-number.html http://www.rebol.org/cgi/gif-number.r Then you can add the link to the script as a normal image tag. This would be the most cross browser friendly method.

I love the inline frame tag, but unfortuneately its not well supported yet. That makes it a bad counter since you would only count those browsers that support it. After viewing your counter I got an idea you might like. You can have your REBOL counter preprocess your web page--much like the way PHP or SSI does. Have it parse your web page looking for a special text like ~counter. Once this text is found it would replace it with the actual count. This way would let you use your favorite html editor to create and edit the page, and still have an easy to create program. You could also use tags like , just 12345, or whatever sequence you feel appropriate. This could be useful for doing quotes of the day, random jokes, time and date, and all that other fun stuff. This would only add about 3 or 4 more lines to your existing counter script. Hint: use the replace function. You will also need to tell the webserver that your printing html by first printing "Content-type: text/html^(0A)^(0A)". Best of all, it would count everytime. --Ryan [EMAIL PROTECTED] wrote: > Hello allenk, > > Wednesday, May 24, 2000, 12:47:15 PM, you wrote: > > apca> http://www.worldmerchantltd.com/cgi-bin/counter.r> > apca> > > Only in IE5... hm..

[REBOL] [REBOL] [REBOL] Default Port Values? Amended Re:
Hi Tim, A) Initiliazing Words? why do you want to initialize the word port to some value before opening it? Let us assume you did NOT initialize it. Then there are three possible states for the word port. It does not exist yet, because the port has not been opened. You can check for this condition using value? >> value? 'port == false once the word port has been assigned to some value? 'port returns true. This value could be an open port! or something else. Second condition is port has been opened. Third condition is port has been closed. Note that when a port has been closed, it still qualifies as a value of type port!. Trying to read from or write to a closed port will generate an error. (Maybe that is the source of some of your errors? Can have you been trying to read from or write to a closed port, because the port was not none?) 3 -> 2 You may want to reduce complexity by dealing with two port states: exists or open. Then, whenever you close a port, use unset to get rid of the word. Instead of using the close function, you use the following shut function that does it for you: shut: func ['port] [ if port? get port [ close get port unset port ] ] >> value? 'port == false >> port: open %file >> value? 'port == true >> shut port >> value? 'port == false Of course it's more port-like (portly?) to ask the port if its open, instead of asking it if it exists. Also, if it exists, it better reference a port! value. Let's do that: open?: func ['port] [ return all [ value? port port? get port ] ] >> open? port == false >> port: open %file >> open? port == true >> shut port >> open? port == false Using the three functions open?, open, and shut consistently, instead of using close will narrow words referencing ports to two states. If open? port returns true, then the word port is pointing at an open port that was opened using open. If open? port is false, then there is no word port and - if port previously referenced an open port - then that port has been closed. For instance you would say: if open? port [safe-close port] and by having used open? you would be guaranteed that that the port you are passing to safe-close is an open port, not some other type of value, not a closed port, and it exists. 3 -> 5? When you initialize port to some non-port value, you are introducing a fourth and a fifth state for the word port, in addition to the three default states. Besides being 1. existent/non-existent 2. open 3. closed the word port can now also be 4. none 5. a type that is not port!. (namely none!) 1. A function may fail because it expects a port! type value, BUT it is passed the word port when it references the value none, i.e. a none! type value. 2. A function may fail because the having checked for none, it determines that the value of port is NOT none, and it now attempts to access the port. BUT the port - even though it is not none - is closed, not open, and accessing it generates an error message. My personal preference is to reduce complexity. Two states suits me better than five. If I thought that declaring values before using them is important, I would certainly prefer none over an empty block. A value set to none can easily be identified using if or either, because none evaluates to a logical false value. An empty block evaluates to a logical true value. It complicates matters. With respect to your example code, be sure to use a uniform function interface. It does not help you, if you test for the types of arguments occassionally and not consistently. In the following example you note that once you do and once you don't get an error message. Apparently you overlooked that in one function you are checking for the type of the argument being passed and in the other version of the function you do not: argument is type checked here: | | With type checking:safe-close: func [p[port!]][if p [close p]] Without type checking: safe-close: func [p][if p <> [] [close p]] | | No type checking here You comment saying: lets say dufus: none safe-close dufus generates Script Error: safe-close expected p argument of type: port The error message is reporting that your safe-close function is checking for the type of the passed argument. You require that the argument be of type port! safe-close: func [p [port!]] ... but you are passing a value of type none! Therefore you get the error message. You would be getting the same error message, if you used [] instead of none with this version of the safe-close function, because you would be passing a value of type block!, while this version of safe-close expects a value of type port!. block! <> port! >>> HOWEVER: if I

[REBOL] Windows NT 4.0 / Apache / Rebol Configuration Re:(3)
Thanks to everyone who helped with the Apache setup. It turns out it was my own fault. I had configured Apache to log in as IUSR_APACHE and denied access to that user to the rest of the file system, including the Rebol directory. Fixed the permissions and it works fine. FWIW: I did not need to uncomment the httpd.conf entry for "#AddHandler cgi-script .cgi" since my script files are in the cgi-bin directory. I did need to use the ".cgi" extension on my Rebol script files. Both "#!e:/rebol/rebol.exe -cs" and "#! e:\rebol\rebol.exe" worked fine.

(My configurations etc are > listed in the message below.) When you run Rebol in --cgi mode, it is only supposed to produce output to a webserver, never to the console! Otherwise if your CGI would be working, it would open a rebol window everytime you ran a cgi script (apache doesn't have its own console). But is CGI running yet? Have you tried a script like this: #!path/to/rebol.exe -cs REBOL [] print "Content-Type: text/plain^/^/" print "Just testing!" Name this script test.cgi and place it in your /cgi-bin/ as defined in your config. The association you made for Rebol only matters to your NT system, NOT to Apache, if you would like to set Apache up for .r execution (and I could never be bothered) you must add an AddHandler command to your config. Put one below "AddHandler cgi-script .cgi" that reads: "AddHandler cgi-script .r" and that should work (never tried it, though)... Good luck, Rachid
