I have a little question of Red's camera function.

I have tried the camera face in this article; http://helpin.red/Faces.html

I have compiled the second source code, which enables a button to save the current stream as a jpeg-format file.

However, the saved image files are nothing but an immaculately white.

I consider this to be a bug regarding the image process or binary file output.

Moreover, my operating system is macOS High Sierra(10.13.6), and I am utilizing Red 0.6.3 with the Visual Studio Code(1.29.1) plugin.

Perhaps you should update to the latest version first, before pointing out bugs.

And there's certainly no need in double posting your questions in different rooms.

wrong syntax, but the error message is weird too:

>> 1 < 2 or 2 > 3
*** Script Error: < does not allow integer! for its value2 argument
*** Where: <
*** Stack:

Toomas Vooglaid

@toomasv

Should be Error: or does not allow...
Somehow op in message is not updated?

Boleslav Březovský

@rebolek

but or allows integer!

Toomas Vooglaid

@toomasv

>> true or 3
*** Script Error: or does not allow integer! for its value2 argument

Boleslav Březovský

@rebolek

Yeah, but

>> 2 or 3
== 3

The error message probably should say something like incompatible values

Toomas Vooglaid

@toomasv

Yes

Can you explain treatment of integers by or and and?

Boleslav Březovský

@rebolek

@toomasv like in C.

1 or 2 -> 3

in binary: 01 or 10 -> 11

Toomas Vooglaid

@toomasv

Ok, thanks!

0x11

@codenoid

how it's goig

going

Boleslav Březovský

@rebolek

Hi @codenoid

Vladimir Vasilyev

@9214

Infix logic operators dispatch on leftmost (rightmost?) operand, so IMO this is an expected error message.

Boleslav Březovský

@rebolek

If I compare R2 and Red:

>> 1 < 2 or 2 > 3
*** Script Error: < does not allow integer! for its value2 argument
*** Where: <
*** Stack:

>> 1 < 2 or 2 > 3
** Script Error: Expected one of: logic! - not: integer!
** Near: 1 < 2 or 2

Rebol message seems to make more sense

Vladimir Vasilyev

@9214

Agreed.

@9214 Hi, regarding the solution you've presented yesterday, there's something I don't understand.
What I've seen and done is ... into [rules]. You've built something like ... into [one rule] [another rule] third rule and the third rule is not in a block.
Another thing is the first block of rules [keep pick to end]. I read something about pick in parse context, but could never arrive at such formulation by myself based solely on that.
Would you mind explaining all this?

Vladimir Vasilyev

@9214

Can you elaborate on "not a block" part? As for pick, see here. It basically collects matched values one-by-one instead of collecting matched group as a "unity".

Luis Vale Mendes

@lpvm

It's getting more clear, now, but yet not fully bright...
You've build into [keep pick to end]. To play with this, I tried into [keep pick to ":" to end] if the minute part of the time was not important. But returns [].

Shouldn't it return everything up to the hour part?

Vladimir Vasilyev

@9214

>> parse ["123:456"][collect [into [keep pick to ":" to end]]]
== [#"1" #"2" #"3"]
>> parse ["123:456"][collect [into [keep to ":" to end]]]
== ["123"]

Luis Vale Mendes

@lpvm

Taking your previous example:

input: [
    "[1518-02-24 23:58] Guard #853 begins shift"
    "[1518-02-25 00:20] falls asleep"
    "[1518-02-25 00:43] wakes up"
]

forall input [
    probe parse load input/1 [
        collect [
            into [keep pick to ":"  to end ]                    ;  inserting `to ":"`
            [thru set ID keep issue! | keep (ID)]
            set action skip keep (index? find actions action)

        ]
    ]
]
==  []

Vladimir Vasilyev

@9214

How can it work if you just loaded the string?

Luis Vale Mendes

@lpvm

Fine, skipped that one. Thank you for your time, patience and overall help @9214

Vladimir Vasilyev

@9214

@lpvm no problem, have fun. :wink:

Luis Vale Mendes

@lpvm

Spot on, that's really my thrive at this phase on my life!

Toomas Vooglaid

@toomasv

What structure did you choose for representing/gathering Day4 data?

Luis Vale Mendes

@lpvm

Hi @toomasv I haven't yet studied your code proposal and haven't choose any yet.

LP Olivier

@olivier_lp_twitter

Is a multitasking or multithreading implementation planned ?

Vladimir Vasilyev

@9214

@olivier_lp_twitter consult the roadmap.

LP Olivier

@olivier_lp_twitter

@9214 thanx, i got my answer :-)

rpherman

@rpherman

@greggirwin I put the DLL in the same folder as the executable. I think it is a 32 bit / 64 bit issue. I am running 64 bit Red, and I saw a snippet about redCV being 32 bit.

Vladimir Vasilyev

@9214

@rpherman there's no 64-bit Red.

Hi there. winter + time = programmingtime ### May i ask for news about the compiling of a android .apk executable program file in red ? Are there any news ? Pleased to share them here. ## signed by The barbarian programmer ##

Vladimir Vasilyev

@9214

@Mennohexo read the latest blog post, esp. P.6:

Android will come after Full I/O

Senenmut

@Senenmut

oh that's great news. thanks. The only tool right now is RFO Basic but they have a little slowdown in development , however it still works. Noone wants to load hundreds of MB and install a shop of hocus pokus like the official java android solution is. ha ## To professional programming frames slow down production ideas. Is my view. Few other think too. ##BP

@Senenmut

i mean the dangerous programmer named : iArnold

ok. its a programmers joke. really. Thanks and see you again here. Regards BP
