13:14 <aw-> abu[m]: here?

13:17 <abu[m]> Hi aw-!

13:17 <aw-> hi

13:19 <aw-> i need help

13:19 <aw-> trying to do something like: (until (= *X (myfun)) (myfun))

13:19 <aw-> but it seems weird

13:20 <abu[m]> yes, it checks only every second time

13:21 <abu[m]> Why not (until (= *X (myfun))) ?

13:24 <aw-> oh

13:24 <aw-> haha!

13:24 <aw-> yeah that works, thanks!

13:25 <abu[m]> \☺/

13:26 <aw-> every other stupid programming language makes me forget how easy and simple it is to do these things in PicoLisp

13:26 <abu[m]> indeed :)

13:50 <beneroth> ^^

13:50 <beneroth> hi aw- :)

14:46 <aw-> hi beneroth

14:50 <aw-> i'm trying to parse a stream of data

14:50 <aw-> struggling to find the start of the packet

14:51 <abu[m]> Is it utf8 ? If so, then 'from'

14:52 <aw-> start/end.. there's a few approaches, the one i'm using is first skipping all data until i find the "end of packet" bytes, then searching for the "start of packet" bytes, then parsing normally from there until "end of packet" (and repeat)

14:52 <aw-> no it's not utf8

14:52 <abu[m]> ok

14:52 <abu[m]> So you use (rd 1)?

14:52 <aw-> yes (rd 1)

14:53 <abu[m]> Ok

14:54 <abu[m]> What if you first read some chunk inti a buffer?

14:54 <aw-> (until (= (rd 1) *Start)) (parse data) (until (= (rd 1) *End))

14:54 <aw-> something like that

14:54 <abu[m]> yeah

14:55 <aw-> yes i could read into a buffer that it'll block if there's not enough data

14:56 <aw-> i'm not sure..

14:57 <abu[m]> Byte by byte with 'rd' is probably easier (though slower)

14:58 <abu[m]> In (until (= (rd 1) *Start ... you must also check for EOF

14:59 <abu[m]> i.e. NIL

15:00 <aw-> right... otherwise it blocks

15:00 <aw-> hmmm

15:00 <aw-> maybe

15:01 <aw-> i need to think more about this

15:01 <abu[m]> Perhaps (loop (NIL (rd s)) (when (= @ *Start ...

15:01 <abu[m]> (rd 1) I mean

15:01 <aw-> ah, i tried something like that

15:01 <aw-> but I couldn't get the @ to be the value i want

15:01 <aw-> @ was like.. /bin/bash

15:02 <aw-> instead of the byte read from (rd 1)

15:02 <abu[m]> Sorry, 10 min.

15:02 <aw-> actually i need to sleep

15:03 <aw-> i'll try again tomorrow, g'nite

15:03 <aw-> thanks for the help

15:09 <abu[m]> ok, good night! :)
