Parsing problem
[1/6] from: blackeye::subdimension::com at: 14-Nov-2002 22:19
Hello, i am new to rebol and i have a parsing problem. If somebody could help me, i'd
be grateful.
Here is the code :
url: "www.asdfasdf.com:123/path/path/file.htm"
parse/all url [ copy host [ [to ":" skip copy port to "/" ] | [ to "/"]] copy path
to end ]
the goal is to have the words:
host = www.asdfasdf.com
port = 80
path = path/path/file.htm
but the host word get the value: www.asdfasdf.com:80
I tried many thins but i have now no idea of the solution.
Tank you

one way that does not use parse
>> ? url
Found these words:
decode-url (function)
purl (object)
to-url (function)
url! (datatype)
url? (action)
>> u: "www.asdfasdf.com:123/path/path/file.htm"
== "www.asdfasdf.com:123/path/path/file.htm"
>> v: copy/part u find u ":"
== "www.asdfasdf.com"
>> w: decode-url u
>> type? w
== object!
>> probe w
make object! [
user: none
pass: none
host: "123"
port-id: none
path: "path/path/"
target: "file.htm"
]

Hi, umm, Blackeye, (:
Parse is probably overkill for what you're trying to do there, as
there's a word (decode-url) to break up URLs into their various
parts. The url does need an http:// though. Anyway, using your
example, this is what decode-url gives (at the REBOL Console)...
>> url: join http:// "www.asdfasdf.com:123/path/path/file.htm"
== http://www.asdfasdf.com:123/path/path/file.htm
>> url-obj: decode-url url
decode-url has created an object there which can be looked at with
probe...
>> probe url-obj
make object! [
user: none
pass: none
host: "www.asdfasdf.com"
port-id: 123
path: "path/path/"
target: "file.htm"
]
as well as being accessed and changed in the normal way...
>> url-obj/host
== "www.asdfasdf.com"
>> url-obj/port-id
== 123
>> join url-obj/path url-obj/target
== "path/path/file.htm"
>> url-obj/port-id: 80
== 80
>> probe url-obj
make object! [
user: none
pass: none
host: "www.asdfasdf.com"
port-id: 80
path: "path/path/"
target: "file.htm"
]
HTH.

with a well formed url 'decode-url does even better ...
>> u: "http://www.asdfasdf.com:123/path/path/file.htm"
== "http://www.asdfasdf.com:123/path/path/file.htm"
>> w: decode-url u
>> probe w
make object! [
user: none
pass: none
host: "www.asdfasdf.com"
port-id: 123
path: "path/path/"
target: "file.htm"
]
