AltME groups: search

I don't know if i am at the right place but here it goes. I have 
been searching for a function that will copy a selected ( or clicked 
) text from an area to the clipborad ( or to a field ).  Is there 
anything in /core or /view that will do such a thing?

Thank you DideC this is what i was looking , i thought that parse 
will do the trick  I just did not know how. All i need to do now 
is see how fast this works with a 100KB text file.

A pair number cant be defined without impair. pair is impair +1 and 
impair is pair +1.  So we have to define both at the same time.  
In logic, the negation is a function where true is false and false 
is true.  Not and complement are native to rebol.  If I try a: not 
'b b: not ''a. asking the value of a, :a, does not return not b but 
false.   Something like this does not seem to work.  What I want 
is criss-crossed functions one defined by the other.  In principle, 
Rebol being functionnal.   It should be simple, a one liner, but 
I am too newbee to find the elegant way to do this.

--Type inference from a newbee point of view:

What if I wanted to form true (but un-native) datatypes ?  To program 
them, I shall use the same method as other types in Rebol: 

To mention the type as its value : seasoning!: seasoning!, like the 
definition of the type money!: 'money.

Rather, I would like to do type inference as they do, for example 
in ML (I adapt the example from Felleisen's LittleMLer):

So I would need to define a new type and verify the type of a word 
with type?
seasoning!: ('salt or 'pepper)
Unfortunately this does not seems possible 
** Script Error: Cannot use or~ on word! value
** Near: 'salt or 'pepper
In Rebol:
>> source integer!
integer!: integer!
type? 1
== integer!
but
natural!: (0 or natural +1)
Type inference:
seasoning? salt
Would like the answer == seasoning
is-of-type? 'salt seasoning
Would like the answer == true

Am I forced to turn to Ocaml to do this?  I am stuck.  Thanks for 
any help!

Gosh, it's too hard for me to do in any reasonable time. I suggest 
looking at the code to figure out the method used, then see if you 
can make your own custom types.

Now if REBOL had unicode support, we could do a Fortress dialect 
for the people that actually know what the operators are supposed 
to be.

I know I've been around for a while, but it's been so long since 
I submitted anything to the REBOL.org script library that all the 
rules have changed. So I'm new again :(


What headers should I add to the script to integrate it into the 
script library? I'd like to BSD license it - how do I indicate that? 
Are there any other headers that are necessary? How do I indicate 
that a minimum version of REBOL is required (Core compatible, but 
I use a few recent features)?


This is related to an extended version of the compress-source function 
I made for the Canvas section.

you can get to it, but it ignores events. again, always-on-top needs 
native support, there's nothing we can do about it.

so how can i get layout of requester(f.e. request-text) to do it 
?> insert tail system/view/sreen-face/pane/1/pane   <what?>

Hey Brian, there is something else you can try, it is a theory I 
have.  Uninstall AltME. Reinstall, and sync back up.  When you think 
it is finished, close out, and start again, let it sync again.
If you are willing....



I never see this "." problem, but many do.  Most people in our office 
don't, and it just might have something to do with the way it was 
originally synced.

is it possible to do some digging if there is an account that is 
currently out of sync?

I do see the I'm New group now.  I did try a number adjust before 
the reinstall went from the default 100 to 1000 to 1 to 100 to 10000 
to 100.  Nothing.

That's the View cache directory (or sandbox if you prefer), which 
gets set by the installer. Although stuff is downloaded to it it 
is more like the Windows application data directory for REBOL, a 
place for (perhaps untrustworthy) scripts to put their stuff. It's 
not really a default download directory as such.


If you want to change it, the easiest way (for a newbie) is to uninstall 
REBOL, move the entire View directory (not the public subdirectory) 
where you want it to be, and reinstall REBOL, specifying the new 
location. If you are more ambitious, the View root directory is stored 
in the registry and can be changed from there. You can't move the 
public subdirectory seperately from the entire View directory though.


Keep in mind that the View root directory is under Application Data 
for good reasons, particularly to make it easier for multiple users 
on the same computer to use REBOL. It's the standard way to do this 
on Windows, and a good idea overall. 


I tend to leave the View root in appdata where it belongs and then 
set a junction point (sort of like a symbolic link for directories 
on NTFS) in some more friendly location so I can get to the data 
easier. I use the axwLink shell extension for this, which you can 
get here: http://arniworld.de/downloads.htm

I'm not really sure that any mobile platforms are supported yet. 
This has something to do with the memory handling of Rebol. I think 
PocketPC is in the works as it's been wanted for some time now.

It sounds like you want to modify the image links in place, so we 
can show you how to do that safely, too.

Simple blocks mappings: I looked in the maillist, but did not find 
for such a simple case.  I am trying to devise a function to map 
values from rebDB to the user UI in rebGui.  So I need to map the 
respective values in two blocks, as in a: [a b c d e] and b: [1 2 
3 4 5], thinking that a foreach would do the mapping.  To no avail?
z: []
foreach [i j] [a b] [append z [i j]]
I want [a 1 b 2 c 3 d 4 e 5]

I would need two foreach, side by side, not to embed one in the other. 
This does not work, but the idea is there.
>> z: []
== []
>> foreach i a foreach j b [append z [i j]]
== 5
>> :z
== [i j i j i j i j i j] -> ?What is the formula?

Integer digits of a string: I want to check if all the digits of 
a string, str: "1984", are integer number, to check the validity 
of a date. Ideally I do not want to use integer to-integer, as in:

check: func [ str [string!] ] [ for n 1 (length? str) 1 [integer? 
to-integer to-string pick str 1] ]. It seems to me that to beg the 
question.  Any more elegant way to do that?

it's not political it's phylosophical issue. Do you prefer people 
having tones of shareware and not paying for them or do you want 
people using freeware and donate what they can to the author ?

I strongly feel that we are joined ideologically in the Syllable 
project by all having reached the conclusion that we want to do something 
new - which was the AtheOS philosophy. The projects that aim to clone 
older systems have to deal with some significant problems. They're 
tied by backwards compatibility, and they're working in an environment 
of decay, because their legacy systems are getting ever more outdated, 
while still having significant numbers of users. This puts a lot 
of pressure on them and often leads to negative attitudes

The BeOS efforts are fractured, but Haiku seems to be doing quite 
well. Nevertheless, they're far behind Syllable. They can test parts 
on BeOS, but their own system is only running at a very basic level. 
They do have interesting pieces of code, and quite a bit of it at 
that. They use a BSD license,  so any code we want, we can integrate 
into Syllable. :-) Soon we will release a port of the OpenBFS file 
system for Syllable

Yes, Xen would awesome. Our kernel would have to be modified to support 
it. Nobody has talked about it yet, but some day someone will do 
it

Do you know how booting works? if i extract the cd to hd and fidle 
with lilo, can i then boot something?

You do have to log in as root, though, to use most of the preference 
applets

Pretty similar to my requirements. We're getting there, but it will 
take a while. We do have a stated goal for this year to get the system 
ready to be the primary system for ourselves

If they wanted to support Debian, they would have provided a .deb 
- .tar.gz packages always need a little hacking. They do document 
their restrictions on their web site.

My complete build system for building the entire Syllable operating 
system is 1600 lines of Ruby. 13,000 lines should be able to do something 
constructive

I managed to skip past the grub notes the first time, so I had to 
reinstall. :) Looks like I have to do it again.

You don't have to re-install Syllable, but you do have to follow 
the GrUB installation procedure in the installation instructions

Is it easy to change that, do you think ?

If you hace to do it again, you could try to page through the instructions 
with the space bar. That's the standard way with the pager that is 
used

The thing to remember about the file system is that journaling works 
well, unless you had a lot of file activity just before hard booting. 
This can damage your file system. A good thing to do after heavy 
file activity like big copies or downloads is to issue a "sync" command 
in the terminal

Kaj - can I boot Syllable from CD or do I have to have partition 
for it?

Since i can do parsing, but when i look at xml-docu, i do not know 
where to start. If someone could break that up for me..

I am with Chris here. XML may not be silver bullet, but you can do 
nothing if the other party decides to use and communicate using XML 
- you either can handle, or you can't - simple as that. You can argue 
with them about rebol and its blocks, they will not care :-)

I'd never say XML was a silver bullet -- I wouldn't use Rebol if 
I did -- but it is a pain not to be able to do simple manipulation, 
especially when there is a standard method laid out for doing so.

the thing is simple - you are ither able to read, change, store XML 
files, or not, simple as that .... so what Chris means is - being 
able to read XML into DOM like structure, then do something with 
particular fields, store it back into XML ...

With the block position format, you can just test the first member 
to get the type of the data item, and then do something like this 
to access it:

    set a: context [name: namespace: attributes: contents: none] elem
or perhaps this
    set [name namespace attributes contents] elem

This would probably be easier to do using block parsing.

I agree.....

I tend to avoid hash! and use straight block! for values I'm reloaded 
from external storage.
Block! makes the loading much faster. 

Hash! may be faster once loaded, but I don't do enough processing 
to offset the loading disadvantage.

Since 2000, exclusively REBOL work! But I do not know how long I 
will be able to stand the position, because, despite the great results, 
we got a lot of opposition (not a standard, too cheap, no future, 
en so on...) :(

well, try to keep up your good work. What is standard anyway? Or 
just make some calculation, how using different technology makes 
process more complicated/expensive (unless your opponents don't use 
other open-source technology, e.g. python) ... the bad thing is, 
e.g. here in our company, that the price is not always deciding factor. 
RT does wery bad job here. Our managers want to read some success 
stories, want to see list of other customers who do use such technology 
.... some case studies etc. Maybe simply Europe uses different kind 
of logic than US.

Do you want Rebol to run C code?

Doing my first steps with REBOL I tried to do something with XML

(reading/eventually modifing/writing). I looked for some scripts 
helping
me to do this and found:

1. xml2rebxml/rebxml2xml:
    I got the following problems:
    - missing/loosing comments
    - missing/loosing elements - that's realy serious
    my steps were:
      my-doc: xml2rebxml read %simple.xml
      write %simple2.xml rebxml2xml my-doc


    The second documents finishes outputting elements after some comment
    block in
     the source xml doc.

 2. xml-parse/xml-object:

     The versions I found on the reb library didn't work, I used some

     older versions from rebXR-1.3.0, I've got my objects, but it would 
     be

     nice to have a third module like xml-write to get the object tree
     back to xml. Is somebody developing something like this?

 3. mt.r:

     I tried to figure out how it works. Basically I can write some XML

     based on a REBOL block but I couldn't figure out how to define the

     rules about elements and attributes. Where can I find an example

     about writing for instance svg with mt.r, how looks the coresponding
     REBOL block and the rules for svg?


Where can I find more about xml and REBOL, I think it would be very 
nice
to have some REBOL scripts, doing things like 
   some-elem: xml-create [ elem "foo" namespace "myns" attribs [
                                     bar "something"
                                     xyz "123"]
                                     ]
   xml-modify [ elem another-elem append some-elem ]
and finally
   xml-write %mynewxml.xml my-doc


Is somebody developing something like this with REBOL? Some scripts 
giving

me the same comfort in REBOL like maybe XOM (http://www.xom.nu) is 
giving
for XML in Java. Of course done with some nice REBOL dialects?

What is the above mentioned "EasyXML" - is it available for use/testing?

Thank you for any tips, carsten

Carsten, the script still strip comments. Do you need the comments 
to be lead through to the output? (I'm a bit in two minds about, 
how it should work.)

I liked the discussion Chris and Brian hold here week or so ago ... 
simply let's find a way of how to work with XML in rebol - once we 
know what do we want, we can start coding ...

John, I've downloaded it from your website - thank you!

One more question from an unexperienced REBOL-user:

What is the most commen way to enhance a block I've got with xml2rebxml, 
source is
<?xml version="1.0" encoding="iso-8859-1"?>
<chapter id="ch_testxml" name="Test XML">
  <title>A chapter with some xml tests</title>
  <sect1 id="sct_about" name="About my Tests">
    <title>What kind of tests I will do</title>
    <body>
      <para>Some simple paragraph.</para>
    </body>
  </sect1>
</chapter>

After read in the file with
my-doc: xml2rebxml read %test.xml

I'd like to insert a second sect1-element in the block my-doc, whats 
the best way - just to avoid some stupid mistakes.

Carsten, to insert second sect1, do something like:

append last my-doc [sect1 id "sct_about" name "Another about" [title 
"etc....."]]

if you set the encoding on the server side, you don't need to convert 
your strings in Rebol but let the server to do that job

janeks: unfortunately the pdf format does not support unicode, so 
that's not trivial to do... i will do it, eventually.

yes, what a pity.  i wonder how you can write a driver for a database 
.... i d like to try to do it just for fun

do you mean MS sql server?

Galt Barber wrote an SQL -Proxy for MS-SQL7 a few years ago. Modifying 
his script I was able to snoop the connections to the Caché DB too.

ok i have the dll and i wonder what to do now .... if anyone can 
give me informations ....

Yes, there's a few  insertions to do on lower-level parts. I'll take 
a few minutes to do it after lunch. Btw, I don't have any pgsql server 
available, nor have time to setup one, so I'll let you test and eventually 
debug the new version. ;-)

Te goal i would like to archive, is to have a dialect to "talk" to 
COM objects. is this to hard to do ? do we realy need this ? all 
cuestions are welcome 

To start i've wrapped a Library called DispHelper, make it a .dll 
and try to see i we can get any thing to work. you can find some 
alpha releases in this link http://www.geocities.com/benjaminmaggi/data/COMLib.zip, 
and some documentation here http://www.geocities.com/benjaminmaggi/doc/comlib.html

Yes, it is wise to do. He integrates with the IDispatch interface 
that all ActiveScripting languages on Windows use. If you want to 
control regular Windows applications this is the way to do it. When 
the .NET scripting interfaces are better established with Monad, 
then you might consider something different for .NET apps, but it 
will be a while before those take precedence. For the next couple 
years, traditional Windows applications are what you have to deal 
with.

I am not the one who does the work in Excel. Accountants do. It is 
not my choice to make, and the choice can't be made at all for historical 
records. At the time they switched to Excel, yes I was the one who 
championed it, but there was no OpenOffice then, no KOffice, no REBOL, 
no Windows 95 even. I am just called in to do the things that are 
over their head and when I'm done, these things usually don't need 
to be done again. Two years from now a new set of problems wil need 
to be solved and they will likely still be using Excel.

It might be necessary to do the COM interface do to circumstances!? 
Maybe the company can't switch any time soon. I was just suggesting, 
that all the powder used to support COM might be better used.

Im atending to CaFeLUG it's an open source 3 days long conference 
with various speakers and discutions, yesterday we have ms "maddog" 
hall, and today i get the chance to listen Roberto Di Cosmo, many 
french and italian people may know im, its has been a truly eye opening 
experience, i guess Argentina like many other countrys who use Privative 
Soft like MS windows (only because we can make the copy) its going 
to make a switch, the ability to copy windows will no longer exist, 
and the only real option is Open source because of the $$$ right 
now i think this will happen in no more than 5 years from now, i 
do not agree with the general idea o MS but i found COM to be a quite 
intresting thing its to sad to see how it's bloated by VB or C# but 
any whay its a nice thing they have. 

So in conclution its a good idea to have COM yes and no... yes because 
it will open a door for rebol and many programers (maybe) and no 
because the thecnology could become useless in 5 years (at least 
to me and people around me) 

I think it will take a few changes to make rebol COM compatible so 
it isn't a great deal programing it for a couple of years it may 
be a good thing to have.

But today there are some great things to do imagine REBOL's capabilityes 
integrated in the desktop a true desktop not the rebol one, REBOL 
stands in the middle between documents messaging information exchange 
etc... etc... just because it can integrate COM ....

i've found a nasty bug on the rebol code, it avoided objects to be 
passed now looks much nicer and works... im working on some pritty 
examples WORD EXEL and more just the one's you can see on MSDN for 
VBS but workin in REBOL !!! wow comming soon ! you cant imagine all 
things you can do with this baby apart from crashing the system :-)

i have to do it that whay

Yes ... I could publish it, as now it is pretty much the same interface 
as Ben's. However, I plan to totally rearrange all that (probably), 
so my distro will be hard to keep up with for a while... Mmm... what 
to do... Work faster I suppose.. :)

I *could* release this version and fork again for future rearrangements, 
but I am not keen to double the work-load...

Ok, what I'll do is send you a zip of the current distro, but with 
not much promise of support. ie. that branch is marked for death. 
I will support your migrating to the new interface when that comes, 
though.

What he said he was going to do was to find a way to provide comlib 
support for those without pro.

Anton, re webspace, send me an email - what do you need to do? private 
ftp space or public web and for how long?

I don't know, I haven't discovered this yet. I will of course put 
it into a demo when / if  I do discover a way to start the app.

Not going to do anything on that for a few days, I think.

just ask DocKimbel to release his xy years old version. He did not 
do that, because RT asked him not to do so. IMO fastcgi is not feature 
which would ruin RT sales. Except secure mode there is very little 
value in the rest of Command - outdated ...

I think it's a little silly having to ask developers not to develop 
something even if it's fairly possible to do.

Yes, you can do the chaining of objects easily, and pass args to 
functions directly, without using the printf-style syntax.

I am quite sure I can do better with rebol, but I would have to turn 
DispHelper inside out to find out the way. As it is, I have left 
DispHelper untouched.

The Speech Reco software is the one that comes built-in with Windows 
XP and Windows Vista (BTW, speech reco in Vista is much better than 
in XP). It analyzes widgets on the screen by running through all 
the windows handles (just about everything on a Windows screen is 
a window) and their labels, so it actually knows there's a menubar 
with a file menu on it so you can do things like say "Menu" "File" 
"Open" and it simply works for almost all native apps. It sends the 
equivalent commands by sending Windows messages to the windows. Problem 
is, since Rebol widgets do not have their own handles, the system 
never finds them, doesn't know they're there or that messages can 
be sent to them...

That ouwl defeat the purpose; the idea is that the system works for 
all apps and that the apps themselves do not need to do anything 
to have it. Wrapping the API and then building it into every single 
app is not a feasible option. Do you think it's possible to adapt 
the Vid and RebGUI dialects to integrate with the SPeech API so everything 
built with those at least would work? (don't know much about how 
dialects work yet)

I don't know of anyone that's wrapped the ability to use native Windows 
controls in a REBOL dialect, though it *might* be possible. I think 
Cal (and maybe Cyphre or Oldes) have emebedded native OS windows 
in a View window. You might also be able to do it by creating your 
own windows, using the API, and then interacting with them behind 
the scenes. It would be a lot of work though, and be highly OS specific.

pekr, I don't believe so. View is essential for those 5 minute apps 
that you need to do for a friend.

If I would consider different UI toolkit, maybe I would look to create 
some GTK or Qt bindings, as other scripting languages try to do ... 
those are existing, and even cross-platform, no?

cyphre, hopefully it wouldn't have to be the end of it. it should 
be the final product that users should pay for and native support 
for GUIs is not the goal but the means. I think it would be a bit 
sad if Rebol had yet another essential component as payware. you 
can do most of this stuff for free on other languages, which would 
cause even smaller motivation for using Rebol as a development platform.


this is why I release my components (LIST-VIEW, Tester, Tab-view, 
TOOLBAR) as BSD licensed freeware. If I didn't, I would have zero 
users.

Cyphre - I also agree with your another pov, which you had in the 
past. It all seems simple at the beginning, but once you delve more 
deeply into it, things start to complicate. Bringing native OS binding 
for Rebol imo would cost many resources. And I believe first version 
would be just ugly wrapper, containing more or less stright conversion, 
using Win32 logic. Isn't there a fact, that others do use other, 
mainly cross-platform bindings? We have View, but wouldn't native 
toolkit project be just reinventing the wheel? Others use tk, gtk, 
qt, wxwidgets, etc.

this also means it would be problematic if one developer were to 
only create developer products, so we shouldn't do that. balance 
between end user and developer products :-)

Just checked out IBprovider, as linked to by Graham, above. I've 
decided not to investigate more of it at this stage. Too much complication 
for me :) I have plenty to do already :) If someone is going to use 
it, that may change things, but I can't just go around investigating 
all the possible OLE applications this COMLib allows you to connect 
to.   (Mmmm.... maybe I'm just not big on databases. It doesn't make 
my blood pulse any faster.)

Is there any way of controlling Firefox using Com?  Or, do we have 
to use XPCOM ?

Is that what you want to do ? Because I just use Privoxy (a web proxy) 
to filter out the ads.

Which makes it tricky to do using Rebol.

excellent - most sites are just reference to hotel search portals. 
 It would be really nice guys, if you would manage some eventual 
hotel discounts for conference participants. Well, maybe a good idea 
would be to advertise DevCon a bit, to know how many ppl would attend. 
Or you can do it other way - reserve e.g. 30 rooms, and use FIFO 
(first in first out) - even email would work to book room, no form 
needed ...

I should attend and have surprises, but I still have to clear the 
budget and the organisation, I should do this by week's end.

Why not also attend general programming and technology conferences? 
Not to be too much off topic, but do REBOLers have a visible profile 
there?

Instead of doing a "competition" why not just have a panel look at 
all that has been done and released in the public.  anyone wishing 
to submit stuff could also do so... if its not yet available or generally 
unknown....

so do we make a checklist to see who is going?

The people from Paris are now checking several possible hotels do 
achieve this. But it is likely that it will not be possible, because 
the conference is taking place in a period when many other colleges 
and universities (Sorbonne,...) are actually organising conferences. 
So are most hotels not able to welcome groups of persons.

Can't you work on the train/car (assuming someone goes with you). 
 This is 2007, do you really need to be "in" the office?

This is 2007, do you really need to be 

in" the office?" so true...  I work from home often, and its actually 
faster than the office cause I have better web and am alone using 
it  :-)

timer/load/save game are done - just trying to see how I should do 
the scoring - whether there are penalties for shuffling, undo etc

not to happy with the general rendering performance im now seeing 
but ill do cleanup tomorrow hopefully.

leave it to the players to do the scoring

but ive got a MMORPG to do in openGL before that :)

The AI isi proving to be a pain :)  I keep thinking - "What would

Then I can copy your list easily, and work on it.

- re help: now that ive spelt ill add it in ;) - ill write some docs 
:(

- re zoom: can do - i need to add a preferences section anyway where 
you can set zoom smoothness etc depending on system speed.
- re numbers justification - will do

- re status output - its there until all the deck cards are ready 
and the deck is also balanced properly - so could be a little while
