Re: [Factor-talk] Printing an HTTP response without accumulation
Thank you for the answer. I defined a new symbol to have access to
stdout and then used with-output-stream* (doesn't work well without
the * of course). Dynamic scope proves to be really useful.
USING: kernel sequences combinators io io.sockets io.encodings.ascii
prettyprint namespaces ;
IN: scratchpad
SYMBOL: old-output-stream
output-stream get old-output-stream set
www.google.com 80 inet
ascii
[
GET / HTTP/1.0\r\n\r\n write flush
old-output-stream get [ [ . ] each-line ] with-output-stream*
]
with-client
Could you explain why output-stream get and output-stream get-
global return different values ?
( scratchpad ) output-stream get
--- Data stack:
T{ pane-stream f ~pane~ }
( scratchpad ) output-stream get-global
--- Data stack:
T{ pane-stream f ~pane~ }
T{ encoder f ~output-port~ utf8 }
( scratchpad )

Hi,
You can work with multiple streams at a time by using the stream-*
words, instead of words such as readln. For example, readln is defined
as
: readln ( -- line ) input-stream get stream-readln ;
If you use the stream-* version, you can pass the stream around on the
stack or put it in a variable, and work with multiple streams. You
still have to use with-disposal or with-destructors to ensure the
streams get closed in the event of an error. Also,
[ readln dup ] [ ] [ drop ] produce
is the same same as
input-stream get lines
There is also an each-line combinator which applies a quotation to
each line; this runs in constant space, instead of 'lines' which
slurps everything into memory.
Hope this helps,
Slava

Hello,
I want to print the response given by a Web server using socket
primitives (not an HTTP library). I managed to produce the following
working code running in the factor Workspace.

ascii
[
GET / HTTP/1.0\r\n\r\n write flush
[ readln dup ] [ ] [ drop ] produce

with-client
[ . ] each
But if I prefer to print the HTTP reponse directly in the quotation
used by with-client instead of returning a result and then printing
it
with [ . ] each, what should I do ?
Indeed the default input and output streams are rebound by with-
client
and thus inside the quotation I do not have access to stdout (the
output stream to the console). It took me some time to realize this
and have a working code. I thought of getting access to the output
stream stored in the global namespace but it doesn't work (\ output-
stream get-global). In fact that doesn't make sense maybe. I also
thought of using with-output-stream but I can't see how to place it
in
the code since I need two different output-streams at the same time.
Also, if you have any comment, insight or remark about the code,
please let me know.
Thank in advance,

[Factor-talk] Accessing multiple slots without using dup and swap
Hello,
I saw that the stack effect of every slot reader slot is ( object --
value ). Thus the object is popped off the stack. If I want to get the
value of another slot, I do not have the object to query it. So I have
to dup it first.
How can I do this the idiomatic way ?
Suppose that I have a rectangle class defined as (code kept to a bare
minimum for the sake of clarity):
TUPLE: rectangle { width float } { height float } ;
Now I define a method to calculate the area of a rectangle. Note the
use of dup and swap to access both slots. I feel that there should be
a better way to access them.
M: rectangle area
dup width swap height * ;
I can use it like this:
rectangle
100 width
50 height
area .
I thought of doing like this:
SYMBOL: temp
M: rectangle area
temp [ temp get width temp get height * ] with-variable ;
But now I have an implementation detail (the fact that temp is a
symbol) that is leaking out of the method body. It doesn't feel right.
I should be able to avoid SYMBOL and use \ temp but Factor curiously
complains: Word not found in current vocabulary search path. The \
parsing word should avoid trying to execute the word. Any idea are
welcome.
Thank in advance,
Ludovic Kuty

Re: [Factor-talk] Accessing multiple slots without using dup and swap
It looks like SYMBOL: can be used anywhere. Thus my example becomes: M: rectangle area SYMBOL: temp temp [ temp get width temp get height * ] with-variable ; And in fact \ temp has no meaning if temp is not defined somewhere. That's why \ + works but not \ not_defined. The documentation for DEFER: states that Due to the way the parser works, words cannot be referenced before they are defined. That answers my second question. However I'm not sure this is the correct way to express access to multiple slots.

Re: [Factor-talk] Accessing multiple slots without using dup and swap
Hi Ludovic,
You might want to check out the bi word. eg:
M: rectangle area
[ width ] [ height ] bi * ;
There is a really nice tutorial at http://elasticdog.com/
Look under the 'combinators' part for a description of the bi (and other
combinators) word.
Thanks,

Re: [Factor-talk] Accessing multiple slots without using dup and swap
SYMBOL: can be used anywhere, but you'll notice that if you define it within the M:, it's still available on the outside. It's generally considered contrary to coding conventions to put SYMBOL: within a word body, since it means the same thing as if it's outside of the word body.

[Factor-talk] Pull request: Better word refactoring in Factor
This patch enhances fuel-refactor-extract-region (or sexp) in two ways: - Before asking for a new word, it scans the buffer for definitions that are equal to the words you're refactoring, offering the choice of using any of them instead of creating a new one. - After performing the refactoring in the current word, it asks you whether you would like to perform the same refactoring in other words which contain the same code. Of course, 'same code' is to be understood modulo whitespace and the like. Lightly tested, bug reports, as always, welcome. BTW, this was quite easy to implement: chalk it up to Factor being concatenative!
