[REBOL] cgi Re:(3)
I am no expert either, but I seem to have it going (at last). I added the following to access.conf Directory /home/ingo/public_html AllowOverride All Options ExecCGI FollowSymLinks order allow,deny allow from all /Directory This allows me to use CGI (ExecCGI) within the dir /home/ingo/public_html and all its sub-dirs. CGI scripts need to have the ending .cgi (this may be changed somewhere else), be runnable, and have a #!rebol -cs in the first line (if the rebol executable is in the same directory) I don't remember if I changed other settings in the apache conffiles, sorry 1. SCRIPT LANGUAGE="REBOL" RUNAT="SEREVR" This is not possible now, but wait for the rebol apache module, due to be in betatest soon. Of course then your provider needs to install it ... (unless you're your own provider) hope this helps Ingo Those were the words of [EMAIL PROTECTED]: I am not an expert on this, and I don't have rebol working under Apache (yet) but the following thoughts occur to me: 1. SCRIPT LANGUAGE="REBOL" RUNAT="SEREVR" could "SEREVR" be misspelled? 2. I use SuSE 6.1 which does a lot of the install/config of Apache for you. I have experimented with Apache only in loopback mode. The main config file is /etc/httpd/httpd.conf and it has a lot of comments in it which provide clues on which settings to fiddle with. I have included some *severely* snipped text from this file to give an idea - it is a starting point - I cannot claim to have retained all the settings you may need to fiddle with. Apache has a lot of documentation - books, web site, and stuff with the distribution. Basically, it seems that any program that Apache calls through the cgi interface must either be loaded as an Apache module, or configured via httpd.conf or both. 3. I hope this is a little help, as I would like to see the detailed instructions myself. On Sat, 27 Nov 1999, you wrote: Well ... I have been waiting for a reply to the message below.

[REBOL] changing server w/set-net (YES!) Re:(3)
Hi Gabriele, glad to see you back in good "form" (pun itended ;-). you wrote: That behaviour is not due to form: Correct. What is it due to? Apparently, the way REBOL treats words in parentheses has changed since version 1: Here's what version 1 used to do: word: "meaning" meaning var2: make paren! [word] (word) var2 (word) :var2 (word) (This was copied from the Version 1 console: 1.0.3.3 (Win32 x86)) Compare to your experiments: word: "meaning" == "meaning" var2: make paren! [word] == (word) var2 == "meaning" :var2 == (word) In version 1 get and evaluation of var2 amounted to the same thing. In the current version this is no longer true. How do you account for the difference between: :var2 == (word) and var2 == "meaning" ? Using :var2 returns something different from evaluating var2. However, the new User's Guide (beta) continues to say: User's Guid (beta) :word Retrieve the word's value, but don't evaluate it. This is useful for referring to functions and other types of data without evaluating them. So, everything would be peachy, if (word) was covered by the vague "... and other types of data ...". Is a word in parentheses a type of data that is evaluated? Not according to the dictionary: "PAREN! Represents the PAREN datatype, both externally to the user and internally within the system. When supplied as an argument to the MAKE function, it specifies the type of value to be created. When provided within the specification of the argument of a function, it requests the interpreter to check that the argument value is of the specified type when the function is evaluated. " For our discussion it is important to note that the dictionary does not document a usage of paren! which leads to the evaluation of a word. My guess is that was introduced after 1.0. Version 2.1 already includes the new way (word) works. I'd say the dictionary needs to be updated. BTW, if anyone from the REBOL crew is reading along, the following statement in the dictionary entry for PAREN! also needs to be carefully reworded ;-): "When provided within the specification of the argument of a function, it requests the interpreter to check that the argument value is of the specified type when the function is evaluated. " That was never true. Elan

I haven't seen any responses to challenge #3 (although my email reading has been spotty, thanks to some turkey...) so the following is my first posted stab at it. Critiques on performance and style are welcome, as I am still working on which ideas in PROLOG, LISP, etc. are viable in REBOL and which need to be re-thought. NB: I consider these "functional" -- although local variables are utilized -- because the locals are only initialized once and are never REassigned. This is well-known shorthand (e.g. "let" from LISP/SCHEME) where foo: func [arg /local temp] [ temp: (... some expression1 on arg ...) (... some expression2 on temp ...) ] is just a syntactical (and likely a bit faster) variation of baz: func [arg2] [ (... some expression2 on arg2 ...) ] foo: func [arg1] [ baz (... some expression1 on arg1 ...) ] because it uses local definition and expression evaluation instead of (secondary) argument definition and function invocation to do the same computation. ; ; transform a (not string!) series (block?, list?, ...) so that ; the first member is un-nested ; pinch: func [arg /local front] [ either all [ series? arg series? front: first arg not any-string? front ][ pinch compose [(first front) (next front) (next arg)] ][ arg ] ] pinch [[["hello" 0] "world" 1] [2 "!" 3]] == ["hello" 0 "world" 1 [2 "!" 3]] ; ; flatten a (not string!) series? by concatenating the first ; element of the pinched argument with the flattened remainder ; of the pinched argument ; ; non-series arguments, string arguments, or empty arguments are ; their own flattened selves ; flatten: func [arg /local loc] [ either all [ series? arg not any-string? arg not empty? arg ][ loc: pinch arg compose [(first loc) (flatten next loc)] ][ arg ] ] flatten [[["hello" 0] "world" 1] [2 "!" 3]] == ["hello" 0 "world" 1 2 "!" 3] ; ; recursively create a result that consists of only the strings ; from the original argument ; _onlystrings: func [arg] [ either empty? arg [ arg ][ either any-string? first arg [ compose [(first arg) (_onlystrings next arg)] ][ _onlystrings next arg ] ] ] ; ; produce the block of strings (per challenge #3) by finding the ; strings in the flattened structure ; onlystrings: func [arg] [ _onlystrings flatten arg ] onlystrings [[["hello" 0] "world" 1] [2 "!" 3]] == ["hello" "world" "!"] onlystrings [[[3 "hello"] [6 "world"] [7 "from" "rebol" 21]] [[[["hi"] ["this" ['aword] "is"] "a"] "test"]] == ["hello" "world" "from" "rebol" "hi" "this" "is" "a" "test"] Thus I think it IS possible to do challenge #3 in REBOL. -jn-

I'll post here as it really needs redoing. In Andrew Grossman's

block of name value pairs and sent them to a url as url-encoded cookies.
I copied the word definition so that there are three words with slightly
different functions.
tmp: http-get url [ name1 cookie1 name2 cookie2 .. ] - which fetches the
page specified by url as well as sending the cookies in the header.
This word is untested.
tmp: http-post url [ name1 value1 name2 value2 .. ] - which posts the
name/value pairs to the form at url. No cookies are sent, but up to 2
cookies sent back are saved in a global variable cookie-data, and the
other one in tmp/set-cookie
tmp: http-post-cookie url [ name1 value1 name2 value2 .. ] - which posts
the name/value pairs to the form at url. Cookies saved in cookie-data,
and in cookie-data2 in url-encoded format are sent as part of the
header. Cookies returned are saved.
It would be nice if one of the experts here could fold these words back
into a single word - they share 99% of the same code!
MTNSMS' webserver gave a 500 error when I sent them an empty cookie:

[REBOL] problem with lesser? Re:
Hi Alexander, Your return value is strange. I tried it on my machine and I get: list: [ [[%readme.txt 4-Sep-1998/5:37:08+1:00 139 file "^/"] [[%user.r 26-Nov-1999/17:08:58+1:00 330 file "^/"] [] == [[%readme.txt 4-Sep-1998/5:37:08+1:00 139 file "^/"] [%user.r 26-Nov-1999/17:08:58+1:00 330 fil e "^/"] ] sort/compare list func [a b] [lesser? (second a) (second b)] == [[%readme.txt 4-Sep-1998/5:37:08+1:00 139 file "^/"] [%user.r 26-Nov-1999/17:08:58+1:00 330 fil e "^/"] ] Appears to work here. Elan At 07:47 AM 11/29/99 +0100, you wrote: Hi, i have a problem with the input values for lesser? it should take any type of value. Anyway, used with sort i get an error , but why ?: list: [ [%readme.txt 4-Sep-1998/5:37:08+1:00 139 file "^/"] [%user.r 26-Nov-1999/17:08:58+1:00 330 file "^/"] ] i can compare the date in that way : lesser? (second (first list)) (second (second list)) == true but if i use sort/compare: sort/compare list func [a b] [lesser? (second a) (second b)] i get following error: ** Script Error: Cannot use lesser? on date! value. ** Where: lesser?
