World: r3wp

mucking around, i changed the system/words/insert port/sub-port "^/." 
to system/words/insert port/sub-port "^M^J.^M^J" and that gives an 
error.

oh crap
 <-- isn't this another peeve?

added to checklist

graham, doesn't gmail require tls? it works with ssl too?

appears to.

I've managed to send a few emails to myself using smtp.gmail.com

Rebol []

email: [compkarori-:-gmail-:-com]
pass: "password"
address: [target-:-gmail-:-com]
message: read %your-fully-formed-email.txt

state: 'EHLO

smtp: open/lines ssl://smtp.gmail.com:465
set-modes smtp [secure: true]

forever [
	S: pick smtp 1
	?? S
	if found? S [
		code: copy/part S 3
		?? code
		?? state
	]

	switch/default state [
		EHLO [ 
			insert smtp "EHLO rebol.com" 
			state: 'PLAIN
			while [ S: pick smtp 1 	][ 
				?? S 
				if find/part S "250 " 4 [ 
					print "sending authentication"

     insert smtp join "AUTH PLAIN " enbase rejoin [ email #"^@" email 
     #"^@" pass ]
					break 
				]
			]
		] 
		PLAIN [
			if code = "235" [
				print "authenticated"
				insert smtp REjoin [ "MAIL FROM: <" email ">" ]
				state: 'FROM
			]
			if code = "535" [
				print "credentials incorrect"
				break
			]
		]
		FROM [
			either code = "250" [
				insert smtp rejoin [ "RCPT TO: <" address ">" ]
				state: 'TO	
			][ print "doesn't like me" break ]	
		]
		TO [
			either code = "250" [
				state: 'DATA
				insert smtp "DATA"
			][ print "doesn't like to address" ]
		]
		DATA [
			replace/all message "^/." "^/.."
			insert smtp message
			insert smtp "."
			state: 'END
		]
		END [
			either code = "250" [
				print "message was sent"
				close smtp
				break
			][ print [ "message had some error: " S ] break ]
		]
		
	][ print ["Unknown state" state ] ]

This should work ...

Anyone care to help me test this?

Of course it would be easier to get the protocol working ...

gmail allows you to use their smtp server only using ssl to prevent 
spamming ...

ie. you have to authenticate as a gmail user before you can send 
using their smtp interface.

But this also means that you can now send secure emails to yourself.

the data block should check to see if it is okay to send ...

I would like to test it, but I don't have SSL:(

Just buy R/Command

I think it is kinda silly to have to get R/command just for ssl now 
.. since ssl is required for so many things

I hope it will be free ...

does proxy setting apply even for https?

petr: i think the answer is yes, but i don't remember. i'm not sure 
it has ever been tested though.

graham, what kind of testing help do you need ?  I am going to try 
the script

Just to check it works for a start!  :)

I only got this script to work once .. never again after that!  but 
it works using standard smtp port on other servers.

There's some type of deadlock occuring .... waiting for gmail's smtp 
server to respond to the insert smtp "."

Now, if you  change insert smtp "." with insert smtp "^M^J.^M^J" 
gmail drops the connection

.

I think, it's a shame, that cannot do this:
>> test: func[/a a][probe a]
** Script Error: Duplicate function value: a
** Where: throw-on-error
** Near: func [/a a] [probe a]

as I need so often to write something and have the name same as the 
path :(

yes, that is the limitation - you try to find out intuitive name 
for your function's refinement, but then you want to use intuitive 
names for your words. So I sometimes used underscore for words, but 
it looks ugly ...

One hack is to assign the refinement value to the refinement word 
at the start of the function:
test: func[/a _a][if not none? a [a: :_a] probe a]
You can then just refer to a.

It introduces an ambiguity though -- does none mean no /a refinement 
supplied, or that the value was none ?

in useage after all these years  I've come to realize that verifying 
the refinement itself is less usefull than ingnoring the value if 
its none.  one should usually use none as the fact its not a value, 
so therefor just like a default, or something to ignore.


this kind of useage allows one to rethrow  the function (is that 
the proper term?) with very little fuss.  in a way, this becomes 
exactly like option args in other applications,  ex:

myfunc [count /option opt][
	unless (count: count - 1) = 0 [
		if opt [
			print count
		]
		myfunc/option count opt
	]
]

many people say that rebol is mem hungry... I can say that today 
I was proven otherwise in some way.

a 10MB xml file loaded from the net and loaded with xml2rebxml  took 
about 100mb of ram.  the same file loaded in firefox  took up 600mb 
of ram.  I was pretty shocked !

10mb of string becomes 600MB of binary xml objects... this is just 
insane.

Maxim, "rethrow": I would say "recursing into" myfunc or maybe "re-calling" 
myfunc. "Rethrow" is more for error handling.

... error handling or "quick exit" flow control.

that's what I was wondering... somehow rethrow sounded cooler  ;-)

juggling?

I have question WRT to error handling:

If I use

make error! "problem"

Immediatly an error message is printed to console. How can I catch 
this? I just want to return an error that I can catch an DISARM to 
get an error-object. Without anything printed to the console.

Wrap the target code in an attempt:

   attempt [oops: make error! "problem"]
   if error? oops [probe disarm oops]

ah, I tried it with TRY etc.

The MAKE error stuff is return from a function.

For example I call:
	a-function 1


and if this function has an error, it calls an error-function that 
ends with: make error! ...

I can't do: attempt [a: a-function] to getback the error.

This works for me:
a-function: func [] [make error! "problem"]
error? a: try [a-function]
***

If that's not quite what you have in mind, take a look at 'throw 
and 'catch -- they may be more suited.

Ok, is this error than gone? It looks like within the error-object/near 
there is an other error. So I can handle the first one but as soon 
as I do something, I get the next output...

Ah, damn, there was an other error in the code...
