It's really low priority.

It would be nice to have, but compiling is so easy that it's really not a problem.

GiuseppeChillemi

@GiuseppeChillemi

@rebolek Excuse my ignorance: what does mean "building a function at runtime ?" could you make an example ?

Vladimir Vasilyev

@9214

How can @rebolek make an example if it's not implemented?

Boleslav Březovský

@rebolek

@GiuseppeChillemi it means building a Red/System function at runtime. Are you using Red/System?

GiuseppeChillemi

@GiuseppeChillemi

@9214 No

Pardon

@rebolek No

Boleslav Březovský

@rebolek

Then you should forget about it and enjoy the world as it is.

GiuseppeChillemi

@GiuseppeChillemi

@9214 I tought that "building a function at runtime" was something related to code like

a: func [] []

In RED

But built with COMPOSE

Boleslav Březovský

@rebolek

Nope, this is only related to Red/System.

GiuseppeChillemi

@GiuseppeChillemi

Ok, so I can leave without it (by now !)

Vladimir Vasilyev

@9214

Jeez... you link a 7 year old blog post about Red compiler and ask if it's possible to create function's at runtime in compiled code - the answer is no, because that would require just-in-time compilation, and current compiler is ahead-of-time one. In general, current compiler cannot support dynamic code.

You can build functions at runtime in interpreter though, that's what func, function and other function constructors do all the time.

Boleslav Březovský

@rebolek

@9214 please...

Vladimir Vasilyev

@9214

You can create them, but you can't modify their specs, because that would require JIT compiler too.

GiuseppeChillemi

@GiuseppeChillemi

Actually I discovered that I can't use a SELECT in place of functions arg block or code block, selecting them form another block which acts as a library. This because after the first run the associated code is maintained and no more selection is possible.
This is the reason why searching for documentation on functions I tought that post was still valid, even after 7 years.

@rebolek

@9214 please...

:-))))

Vladimir can answer in any way he wants to me. I have started to get used and apreciate the good thing of him (talking personally)

Boleslav Březovský

@rebolek

@GiuseppeChillemi of course the docs are still valid, but you need to differentiate between Red and Red/System. If you can post some examples of your code, it would be really helpful.

@GiuseppeChillemi

Vladimir can answer in any way he wants to me.

Great :smile:

GiuseppeChillemi

@GiuseppeChillemi

@rebolek his personality and knowledge makes him the great person he actually is and he does not need to change to "sweeten the pill". I have learnt to read what he writes and not anymore the sound that make his words in my head.

@9214 , @rebolek
So RED/System functions are different from RED functions. The first ones are not so flexible like the last.

Boleslav Březovský

@rebolek

Yup, there's some subtle difference.

nedzadarek

@nedzadarek

@rebolek I don't think I confused someone like him.
Well... do you have better short phrase to describe this?

Rebootr

@Rebootr

Good night. When I try to start red-064.exe, after a while compiling the console closes. While compiling, I looked at the %ProgramData% directory, and a dll and gui-console.exe was created. As soon as the gui-console file has been created, it is deleted and the screen closes, with no error or warning message. Anyone have any idea what's going on? The version red-063.exe works normally.

hiiamboris

@hiiamboris

@Rebootr could be a malicious prank of some "antiviral" software

nedzadarek

@nedzadarek

@Rebootr I don't have such problems. I assume you are on windows. Could you start the console (cmd) and run it from there? You may see some errors this way.

pimgeek

@pimgeek

@nedzadarek it's not synced with the cloud 😅 but possible, I can used thebrain cloud service to publish my local data online. But the cloud service is way too expensive. I plan to develop my personal customized publishing site, as well as a desktop client. 😊

Can I use the red language to manage a sqlite3 database? If I can do that, it will be cross-platform 😊

nedzadarek

@nedzadarek

@pimgeek I see. Well, I'll be waiting for it.

viayuve

@viayuve

how many core red uses when compiling.

Boleslav Březovský

@rebolek

Red does not compile, compiler is written in Rebol. And it's single threaded application.

viayuve

@viayuve

rebol pro sdk :(

Boleslav Březovský

@rebolek

No, you don't need SDK license for compiling.

Free version is enough.

viayuve

@viayuve

i just want fast compilation :cry:

Boleslav Březovský

@rebolek

I don't understand.

viayuve

@viayuve

my one program compilation takes about 5 to 7 min

Boleslav Březovský

@rebolek

That must be a big program.

Anyway. compiler is written in Rebol, so it's interpreted. You can't expect it to run fast. Once it gets rewritten to Red and compiler could be compiled, then it should get faster.

viayuve

@viayuve

0.9.5 right ?

Boleslav Březovský

@rebolek

I guess so.

Rebootr

@Rebootr

@hiiamboris You're right! in the McAfee log I found this: BehavesLike.Win32.Dropper.th, GenericRXGX-HD!9F7841A16EA4

Vladimir Vasilyev

@9214

@Rebootr please report it as a false positive. We fight an uphill battle with AV vendors whose recognize Red as "generic malware", McAfee included.

GaryMiller

@GaryMiller

Couldn't you compress the .exe file before distribution to prevent it from being falsely identified as Malware.

Semseddin Moldibi

@endo64

my one program compilation takes about 5 to 7 min

@viayuve You might compile your program with -r if it is not necessary compile without it, it would be faster (if you don't have R/S in your code of course)

Ops... wrong group

No... right one !

@9214
Well, I have tried the SET words-block values-block solution with no success.

test: function 
[
    action 
    passed-args-block [block!]
]
[

        args-def: [
        add 
        [
            the-path [string!]
            key [word!]
            value [any-type!]
        ]

        del
        [
            the-path [string!]
            key [string!]
        ]
    ]

        function-words: extract select args-def action 2

        set function-words passed-args-block         

]

test 'add ["a-path" "a-key" "a-value"]


probe the-path 
probe key 
probe value

"a-path"
"a-key"
"a-value"
>>>

Words set into function seems to exists after function exit:
