Furthermore:


Red can input some Unicode and print some Unicode. That's enough 
to support the test suite, but mostly useless in real life programs

 I must have missed the point in time when Red was declared beta. 
 :-) AFAICT, Red is not yet ready for real-life programs (Red/System 
 is though).

It's not even true that I/O is to be done, because I support it

 Reading how you put it, I just hope you still remember which version 
 is the official one? ;-)

Really, I don't feel like spending more time on this. Let's agree 
to disagree

I feel the joy in my Red work slipping away from me

I have showered Red with praise on many occasions. Why is it such 
a problem to have some criticism, too?

Well, I don't understand all the fuss. Of course, eventual false 
claims should be corrected, but it feels like selecting one feature, 
knowing we are not there yet, and trying it to push it forward, reshifting 
other priorities? If someone else would wait for dynamic libraries, 
and Doc now switched the focus, would we see another complaints from 
 someone else, that dynamic libraries are not yet fully supported?

If dyn-lib is around the corner, let's better ask Doc, what is imediatelly 
next focus of implementation. IIRC, it should be objects, needed-by 
and followed by I/O. And if Doc says, that more Unicode stuff comes 
with I/O implementation, what timeframe are we talking about? 2-3 
months? Well, not sure how much you are kept stuck with such a timeframe, 
but maybe even you can wait?

OTOH - it seems, that for now, you found/implemented interim solution? 
I believe that if Doc could add full support in 2-3 days, he could 
reshift the priorities, but if it really depends on I/O, then let's 
say - first things first ....

And as for the criticism - it is OK. It is just that we can feel 
you are not happy about the current state of Unicode support, and 
as I know Doc, he would like to please us all, so I can imagine it 
kind of creates some push on him :-)

There is as I read this a different issue. Dock want Red to be as 
complete as posible, Kaj wants it to officially useable. Kaj really 
needs UTF-8 (and or Latin-1) character support, for getting this, 
I guess this has to do with the Syllable operating system amongst 
others.

I would like Red to support time and random functions as natives 
and (Gregg is one of your mezz funcs REJOIN ? I want that too) be 
able to connect to a MySQL database so I can dump PHP for some webdevelopment.

Besdies that we all love to see a VID (like) solution for display 
and creating apps. 

We have to be patient agreed 100% amongst everybody? Where the roadmap 
mentions all things to progress Red, above things are not on that 
list. I want Red to have enough to make it useable in production 
and after that expand, imho that is the way to really attrackt more 
funding/enthousiast programmers and make sure current support does 
not fade/ loose interest.

I think, and hope, the conflict over this will fade soon, and everyone 
will be happy again. We're just all so anxious for the things we 
each need, and Doc has made such great progress that it seems like 
Red should be almost ready to use. I was going to post that REJOIN 
wasn't stable yet, but decided to test it on my latest console build 
and it seems to work great.

rejoin: func [

 "Returns a new string (or same series type as block/1) made from 
 reduced values."
	block [block!]
	/local op
][
	either empty? block: reduce block [block] [
		op: either series? first block [:copy] [:form]
		append op first block next block
	]
]

Why is it such a problem to have some criticism, too?

 There is no problem with that, and believe me, you can't be more 
 critical on Red that I am myself. But I find it really unfair to 
 paint a bad picture of whole Red because some features that are planned 
 are not yet implemented. 


I can't go faster than the music, to get I/O done with required encoders/decoders, 
I need to setup the ports/devices infrastructure. To do that, I need 
objects support done. Also, as shown by my entries on Red Trello 
page, error! (and typeset!) support and getting a Unicode runtime 
lexer are even more prioritary to make Red "more usable for real-world 
apps". Moreover, when you manage a lot of tasks, some of them marked 
as "important" that keep been postponed because of other more urgent 
ones, will at some point become "urgent" themselves. That is what 
is happening with shared libs support, which is a blocker for getting 
Red on Android and iOS. I'll also probably make a Java bridge prototype 
this week before getting back on other Red features.

Almost forgot about the Trello page. Do you use that page as an interim 
planning for what is actually being worked on? If so, and once you 
have few minutes of spare time (I can imagine you don't :-), maybe 
one sentence reference on the Roadmap page would make it a nice addition:

You can find actual tasks we work on on the following Trello page

 .... it would make feel ppl more dynamic about the project, as Roadmap 
 page is rather static. OTOH we can watch Git commits, twitter, but 
 still if one needs to know, what is an actual priority, and as far 
 as Trello page is being updated, it would make some sense. E.g. "Download" 
 addtion was imo very nic simplification for those starting with Red 
 ...

Nice to read about the JAVA bridge ....

btw - probably stupid question by me uneducated :-) Reading a Trello 
card, I can see task "Extend ELF emitter to support shared library 
generation" - does it mean linux is not supported? Or is ELF anything 
else, than Linux executables?

Andreas is working on Linux shared library support. ELF is not limited 
to executables.

Don't want to bother you with primitive questions, but - why in general, 
there is a need for shared library support, on mobile platforms? 
Can we just have - executables? IIRC, R/S code already worked under 
Droid? Well, I know that .apk is some other format (maybe a zip file 
with some files inside?). Is it that in order to have PROPER app 
support (e.g. via GooglePlay), we need to adhere to some rules, and 
one of those is, we need dynamic libraries?

The need is for bridging Red with the JVM and the objective-c runtime.

Red executables (like R3 ones or any other language compiled to native 
code) are not supported directly by mobile OSes. So, it needs to 
be loaded and called from Java or obj-c, hence the need for shared 
library support.


The experiments with Red/System on Android was limited because using 
such approach, you can't have access to the higher level API, can't 
access GUI and need an hack to get it loaded. My goal was just to 
check that Red/System toolchain was able to produce code that runs 
on Android.

Petr, I didn't ask anyone to switch focus, I just asked for information 
repeatedly. I eventually analysed and fixed the problem myself, with 
help from Peter. If that's not enough, I don't know what is

Doc, I keep repeating, I am not "painting a bad picture of whole 
Red", you make that up, blowing the issue out of proportion

I was genuinely disappointed by the lack of Unicode asymetry, and 
had good cause to expect it based on your publications. I made the 
best effort to gain insight into the situation and contribute a fix

I have been digging out this issue with Kaj privately, and it appears 
that several misunderstandings happened a few weeks ago setting up 
a chain of events that resulted in having an unpleasant (for us and 
others) exchange between me and Kaj in this channel.

Kaj raised 
an issue a few weeks ago and asked for information that I failed 
to give. This was my mistake and I'm sorry for that. We've dug out 
the root reasons for that and have set up better rules to avoid, 
as much as possible, such failure in the future. Kaj's dedication 
for Red is obvious to all, from day one, and I'm grateful to him 
for that.

Actually, after setting up this issue, we've come up with 
some interesting new plans and strategies for Red that we will unfold 
in the next weeks...so stay tuned. ;-)

Yay! Thanks for posting that Doc. I was having a hard time choosing 
which of you to keep as a friend.

And it's easier if you're both there, so I can stand on your shoulders.

Hehe :-) You might want then to take an oxygen mask with you, because 
we're going to jump very high. ;-)

Well, maybe I'll ride your coattails then.

As an aside, I needed a break last night, and looked at some Red 
mezz bits again. I realized that REMOVE-EACH was one of the missing 
natives I had written off for a while, assuming you would get to 
it. But I got impatient and wrote a quick mezz version. Fun stuff.

One of my goals is to have as much working at the mezz level as possible, 
so you don't have to write more natives in these early stages. Once 
we find actual cases that aren't efficient enough, then we can optimize 
them.

e.g., I did all the set functions (union, intersect, etc.), even 
though they aren't optimal. They work, and that will let us port 
code.

Sounds fair enough.

Great ... I can take those PERL books back.

I'm very happy with that, Gregg, I follow the same strategy

It can be compiled, anyway, so it's not that slow

I was looking to take cover just in case a battle of the wizards 
was going to happen!  Glad to hear it has been avoided.

I used to be a Dragon-Wizard level 37 in CircleMUD back when Internet 
was mainly text-only, so this could have become nasty indeed. ;-)

Is there comprehensive updated documentation for RED?

Not yet Paul. Though there is for  Red/System.

interesting new plans and strategies
  sounds good :-)

Doc: what do you mean when you say Textpad doesn't support  Unicode 
? I use Textpad 5.4.2 and see options to set UTF-8 as default text 
encoding and others options for BOM and so on.

Didier: see http://stackoverflow.com/questions/8879277/textpad-and-unicode-full-support

Huh, there are versions 6.x and 7.0 for Textpad, I've missed that, 
but the feature page is not mentioning Unicode at all: http://www.textpad.com/products/textpad/features.html

Sadly the recent (March 2013) TextPad v7 release doesn't fix this 
problem.

Got a reply from Avira, they have processed my report and the fix 
should be soon available: 

https://analysis.avira.com/en/status?uniqueid=KwPWqW429CmT1fNpbHWQgDxQ8ryDHO4T&incidentid=1412216

btw, just curious - what is it generally usefull for, to call Red 
from R/S? I can imagine it in reverse direction, but when you would 
need any such callback?

Mainly for external (from bindings) events propagation to Red level.

It will be also used in the Java and obj-c bridges.

Added new #call compilation directive to enable calling Red functions 
from Red/System.

Syntax:
    #call [<red-fun-name> <arg1> <arg2> ...]

Notes:
- it can be used only in routines body or #system body block.

- only function! value can be invoked (refinements not supported).

- arguments are either literal values or Red/System global/local 
variables.

- type casting (to a Red internal datatype) is allowed in arguments 
(avoids wasting an extra variable).

I think it is worth stressing that this is a feature of the Red compiler 
and is not available to Red/System programs compiled with the Red/System 
compiler.

So you can call Red apps from Red/System, but you can't call Red/System 
apps from Red/System, correct?
