Xie, read-file is a Red/System function that does much more than 
fread. It returns the file content itself as a string, not the number 
of bytes read

Bo, your file must contain "1". The second number is the address 
where it is read into memory

If you want to convert the content of your text file to an integer, 
my C library binding provides to-integer, just like in REBOL

Kaj, you said that 'read-file in Red/System automatically defines 
a large enough memory space for the file.  How about 'read-file-binary? 
 That one has a 'size parameter.  How can one determine how big to 
make that 'size parameter before reading the file?

You don't make it any size. It works the same as read-file and the 
READ function in REBOL: it allocates the storage for you

In the case of read-string you get a c-string!, so you can get the 
size with LENGTH?. For read-file-binary that's not possible, so you 
pass a pointer to an integer! to be informed about the read size

Sorry, read-file

Basically, we have a minifilter driver in Red/System that can be 
installed through an INF file, but when started (using `sc start`) 
we get either error 1058 or error 2 (File not found).

The INF file installs the filter driver as a service, yes.

Yes, still not sure what SC seen as file not found though.  But a 
process monitor from systems internals might tell us that.

Run procmon.exe against it and see if it records a specific file 
not found.

It gives you much more including registry, network, and profiling 
counters in addition to file system calls.

Yeah run against Process Monitor and look for any access denied or 
file not founds or path not found messages.

It stops earlier for Doc. File not found seems to be the driver file 
itself, so it probably doesn't load at all

I am trying to learn Red/System but I have a strange result. When 
I enter this code all works fine, the input line is printed correctly:

#import [
	LIBC-File cdecl [
		get-line: "gets" [
			line	[c-string!]
			return:	[c-string!]
		]
	]
]

foo: ""
get-line foo            ; when run I enter: this is a test
print newline
print foo                  ; Correctly outputs: this is a test


but if I do this;

foo: ""
boo: ""
get-line foo          ; when run I enter: this is a test
boo: foo
print newline
print boo

then I get             ; "thisX @"

or if I enter: hello
it prints out: hellX @


It seems that something in the process of binding foo to boo is messing 
up, but I have no clue what it might be.
Any ideas?

Paul: no much usable info there it seems. What I really need is a 
PDB file specification.

Sorry Doc on the pdb thing.  I don't think your going to find a pdb 
file format.  Closest I seen was this that someone may have been 
trying to reverse engineer https://www.informit.com/articles/article.aspx?p=22685.

It is possible right now to include an external file in the executable.

Also, to be able to see any output in DOS console from an encapped 
Rebol app, I needed to change a flag in the executable file (sub-system: 
`console` instead of `GUI`).

Kensingleton: for writing your own OS, you will need to write a custom 
file emitter for Red/System unless ELF could also be used for that?

Its looking for GLib.reds but I do not see that file in the bindings 
links

The needed files can be found in directories like
http://red.esperconsultancy.nl/Red-GTK/timeline
http://red.esperconsultancy.nl/Red-common/timeline
http://red.esperconsultancy.nl/Red-C-library/timeline
http://red.esperconsultancy.nl/Red-GLib/timeline

Atm I do not have an exhaustive overview of these, unfortunately 
the directory listing is not available to the general public.
What file is linking to GLib.reds?

I publish such links often when a single file is requested

int-to-float causes a error. Or does it? I added some prints and 
inbetween steps
	genrand-real2: func [
		return: [float!] 
		/local result [float!] between [float!] intermediate [integer!]
	][  
	    intermediate: genrand-int32
	    print ["intermediate: " intermediate lf]
		;result: int-to-float genrand-int32
		between: int-to-float intermediate
        print ["between: " between lf]
		result: ((1.0 / 4294967296.0) * between) ;; divided by 2^32 
		return result
	]

ON the second value the program errs:
intermediate: -1734706621
between: -1734706560
-0.40389284491539 intermediate: -1052231088

*** Runtime Error 9: float invalid operation
*** at: 00002033h
logout

When I make my testprogram for user.reds tell me why int-to-float 
behaves like this:
intval: -1052231088
floval: int-to-float intval
print ["intval: " intval " lets floval become: " floval lf]
The output is not a runtime error:
intval: -1052231088 lets floval become: -1052231040

But the print line was not executed in my real program? I only have 
one user.reds file in my directory. Suggestions?

Hello MaxV: Congrats to your first R3GUI app! ;-) I have some questions/notes 
though:

1. Why one needs to download the two DLL files to get R3B running?? 
(not much user friendly IMO)


2. On your Blog page you say: "First of all there are some bugs, 
most of them depends on R3GUI, for example this one: https://github.com/angerangel/r3bazaar/issues/8"

I bet this is not related to R3GUI at all but more to your R3B build. 
The REQUEST-FILE works without any problems in our Saphirion build 
(and I think also the "official" Carl's build works well but haven't 
tried it). I tried to download and run your R3B binary and I can 
confirm the bug is related only to this version so it would be fair 
enough if you remove your R3GUI blaming from the blog entry if possible. 
I know R3GUi is not perfect so maybe you can just change the blame 
for some other which is really related to the framework. Or better 
feel free to ask any questions in RgGUI group here!

3. I've looked into the EDITOR function code and comparing to the 
R3 editor code (which is still twice as big as the R3GUI version 
- but I don't know if they match the features though) the R3GUI code 
looks much cleaner and abstracted that the R2 style even if you are 
not expereienced writing R3GUI apps. Some notes:


3.1 I'm curious why are you accessing the internal AREA style value 
like face/names/tb or aa/names/tb/state/value? Is that for some reason? 
Why you don't use the AREA directly like:
do-actor/style face 'on-key arg 'area
instead of
do-actor/style face/names/tb 'on-key arg 'text-box

or

write (to-file AA-INFO/OPTIONS/text-edit) get-face aa


write (to-file AA-INFO/OPTIONS/text-edit) aa/names/tb/state/value 


3.2 There is "classic" but anoying bug. If you open file requester 
and close it without selecting a file the editor errors out. (but 
you probably already noticed)


3.3 Would be great if you add keyboard shortcuts. It's easy to add 
them. See the layouts-15.r3 file in R3GUI Saphirion package as an 
example.


3.4 Maybe you could try to write your first R3GUI style - MENU It 
would be handy in the editor(and also in other apps) instead of the 
buttons on top.


Anyway, thanks for promoting R3 and R3GUI. I appreciate all your 
efforts!

re 1. Saahirion's builds never needed to have such libraries copied 
in the program dir. I'm using MinGW includes in combination with 
MSYS make to build R3. To me it looks like some problem in your make 
procedure.

re 2. REQUEST-FILE native! has nothing to do with graphics. It is 
present even in the "official" R3 release.

re 3. by "R3 editor" I meant eht EDITOR function you have ennounced

re 3.1 here is quickly cleaned-up version: http://cyphre.mysteria.cz/stuff/editor.r3

re 3.3 Note the keyboard shortcut code stub in the link above, this 
is the way how to support shortcuts in R3GUI. Easy, isn't it?


As I said feel free to blame R3GUI where appropriate, there are surely 
bugs around...the REQUEST-FILE bug just simply have really nothing 
to do with R3GUI but more with your compiled exe.

But I use Windows 8 at work, Windows XP and Windows 7 at home, and 
Linux for development and specialized tasks (like file serving).

What is the link to download r3-gui.r3? There's incrrect link on 
the webpage, leading just to the same page, not target file ...

If it's the r3-osx file from:
http://development.saphirion.com/experimental/

, then I get the following on OS X 10.7.5:

504 ~/r3$ ./r3-osx 
Illegal instruction: 4

The file is dated 2-Jun-2013 21:11

r3-osx                   02-Jun-2013 21:11  513K

yes, it's the correct file

ah, noticed Red's main git page uses some .md file. Thought that 
Github accepted our MD :-)

Robert: "The cool thing with this approach is one really don't need 
anything more than the Android encapper to produce the apk file. 
No need for android NDK, SDK or even JAVA to be installed ;-)"


Do I understand you reimplemented jarsigner, zipalign and the java 
XML binary compiler in Rebol?

One thing I'm curious about, though - what sort of debugging facilities 
are you thinking about? Will there be any hooks for a debugger somewhere 
not too far down the road? Is it possible to create a symbols file 
for these drivers?

The /proc file accesses you've mentioned on Linux are just wrappers 
that rely on kernel drivers. There's no shortcut in modern big systems, 
User app => OS => Hardware.

or you can use the build.r3 do get on-file version

Is there anything in R3 to deal with UTF-16 text (file) ?

I have to modify Windows File in UTF-16 with BOM of #{FFFE}. There 
were previously in ISO, but no more :-(

Basically this files are like .INI file and I have to change values 
inside with Rebol.

I have found that R3 is able to load my UTF16LE file correctly using 
'read/string (it "see" the BOM and transcode it to rebol string!).


Now I have to find a way to write to the file as a UTF-16 with a 
litle endian BOM format.

Which makedoc version should I use to compile those mdp files? I 
used makedoc2.r but the output html file is not correct completely?

ah ... its all in the file  :-)

is this a file type for some batch processing app, or just a hand 
written  note for  memory sake?

It's a formal file for my build system. A build dialect

I just looked at liquid.r

Just a text file would do -- otherwise we're guessing what you mean.

eg. the descriptive text of rebol

--


is lengthy and not focus... it also do not need to be at the top 
of every page...maybe it should go below 'About'

Problem is that the download page *is* a static URL if you go to 
it directly, eg,
    http://www.rebol.org/library/scripts-download/menu-system.r

But of you click the "download script" link while viewing a script, 
you do go via a dynamic URL -- it creates the static one for you 
and then redirects, eg

http://www.rebol.org/cgi-bin/cgiwrap/rebol/download-a-script.r?script-name=menu-system.r


{What we should do is update the static file whenever a script is 
added or updated. That would fix most instances of this....I'll put 
that on the list, thanks]

Thanks......Does the file as downloaded work or is it really incomplete?

The length is as shown in the website, but the file downloaded starts 
with some html, so I guess that some other part is missing.

Neither rebol itself, nor me are able to find a rebol header in the 
file.

You can extract the dll to a file on first run and then link to it, 
but you can't link to an embedded dll directly.

What are you trying to do? Can you get away with downloading the 
dll as a seperate file on first use?

Im just trying to hide the dll to keep things squeaky clean.. what 
i've done is embed the binary, and I'll write it to a file, when 
I'm finished, Ill just remove it.

Sunanda, Can it be a manually maintained xml file until it can be 
automated?  I am doing that for my internal blog until I add the 
automation code to blog. r (that I expect Carl already has on his 
version).  I have a trigger for when a blog article is added to use 
"editor ftp://...../rss.xml"to make whatever additions that I want 
to expose via RSS.  It's suboptimal but I don't have any complaints 
from the people that they have to visit the pages to see What's New. 
 And since they weren't visiting regularly to poll for What's New 
anyway, if the RSS feed it updated a few hours later it is still 
an improvement.

Graham in the All group asked:

<<Is it not true though that you are limited in what you can do with 
rebol.org ? >>
Yes and no.

It's a shared server with the usual sort of quote limits, so that 
stops some of the wilder plans.

On the other hand, the limits are fairly generous. Right now, we 
do these sorts of numbers:
* 150,000 CGI executions per month
* 2.5 gigabytes of data served per month

* 70 megabytes of hard disk used (mainly for the Mailing List archive)


Of course some sort of bandwidth quota would exist with a dedicated 
server too -- that one comes from the ISP, not the box.
---- 

We've had the same problem most of us have had with servers at one 
time or another: REBOL going feral and failing to close tasks. That 
brought down the server once, and got us suspended for about 30 minutes 
until I beseeched forgiveness. Of course, that could happen with 
a dedicated server (no one quite knows why it happens).


Similarly, we get some leak-through from what are supposed to be 
the chinese walls; and that has caused the odd problem: mainly file 
permissions going askew.
---

As Peter said, the main limitation is manpower. There are several 
things under development at rebol.org right now; there is room for 
many other improvement projects too.

have run repack-core.r, then call "explorer .", double-click %qml-ed.r, 
"save html", saved with requester, an alert "Error saving file: Cannot 
open /C/Dokumente und Einstellungen/BN/Anwendungsdaten/rebol/public/www.rebol.org/library/public/template.html"

looks more like a missing file to me.

Tried download again, there is a bug:
|| Downloading:   qml-ed.r/RS-NE+.gif
|| REQUEST FAILED...
|| REBOL.ORG says file not in package

You replied as I was typing....
I think you may be right.......

Looks like the downloader has failed to find the files that contain 
a + in the file names.

That's true -- and it may recreate some cross-platform issues on 
platforms that don't allow + in a file name.
But we should be able to deal with it.
Thanks for the help in isolating the problem.

The upload obviously worked -- "+" is not an illegal file name character 
on either Edgars machine or REBOL.org's current host

The notes on contributing a packgae do have detailed guidelines on 
file naming to avoind problems -- see 2.1 here:

http://www.rebol.org/cgi-bin/cgiwrap/rebol/boiler.r?display=cons-upload-package-files-help.html

But, of course, the author probably wrote the application before 
they had any idea it might be rolled out as a package for use on 
a wide range of platforms.
***

The bottom line is that + ought to work in a file name for the downloader, 
so I'll get it fixed.

the image and css files where not done by me, and although i had 
some suspects while uploading them to rebol.org i didn't want to 
change everything just for that :) i can add a zip file to the package 
if you need me to.

You could create an .htaccess file with the following:

I would probably like to see a cookbook example on some kind of error 
handling/redirecting to file or a nice popup window. I've experienced 
terrified users that call me about "that white text window with cryptic 
messages in it" that crop up on fatal bugs.

config: construct/with load config-file standard-config

where config-file hold the config values as a block. If it's stored 
as an object, you can use 'third to have the block.

config: make standard-config load config-file

DideC -- your method is similar to Henrik's, and has the same limitation: 
sub-objects fields do not propagate as you'd expect.....No f2-2 field 
in 'config here:


     standard-config: make object! [f1: 1 f2: make object! [f2-1: 21 f2-2: 
     22] f3: 3]

As far as I remember, file on http://oldes.multimedia.cz/swf/isn't 
actual?!

IMO it needs mainly needs short route to first swf - eg. a) unpack 
make-swf.zip  in catalog ... b) write [code] - save it as first.rswf 
...... - there was always a problem to start again using it :)

What you should know is, that the dialect is almost useless if you 
don't know how Flash works and don't know the ActionScript. The good 
start is to registed and download SWF file format specification from 
this page: http://www.macromedia.com/licensing/developer/

and download ActionScript help file as well

rebol does not need to zip if exe can do it right. data -> file, 
whatever-zip, read file. slow but could work.

I don't want to give it inside the rswf as it's not so necessary 
(you need it only if you want to examine some foreign swf file)

for example if you do the examples above, you can do: exam-swf/file 
%swf8-blendmode.swf

Interesting: just downloaded this free ActionScript compiler http://www.mtasc.org/
and will try if it would be possible to integrate it with the rswf 
(so I could use *.as file for actions without need to parse it in 
Rebol)

go here: http://www.macromedia.com/cfusion/entitlement/index.cfm?e=file_format
register and download

The dialect file have been updated a little bit, use: do http://box.lebeda.ws/~hmm/rswf/rswf_latest.r

Thanks, the dialect file updatet a little bit again and there are 
3 new (flash8) examples

and updated again, current version 1.0.4 (make sure you use the rswf_latest.r 
file with the new examples (there are two more of them)

How you want to pass AS vars to Rebol? Once you compile the RSWF 
dialect file, you have Flash which has nothing to do with Rebol. 
But you can connect Flash and Rebol using various ways (, getUrl, 
loadVariables or  XMLsocket connections). When I do some bigger projects, 
I do not use one file, but rather more files conected together using 
"include" or "require" tags.

The main reason I started with this rewriting is to better support 
foreign SWF file importing. So you will be for example able to join 
to SWF files into one.

Version 2.7.0 available....

- Fixed bug import-swf (while importing swf file with ExportAssets 
tag)

- Updated layouter (now with new 'Text, 'Scroller, 'ClipHandler and 
'ScrollPane GUIs)

http://box.lebeda.ws/~hmm/rswf/rswf_latest.r
http://box.lebeda.ws/~hmm/rswf/rswf_2.7.0.r


New example script with used ScrollPane is here: http://box.lebeda.ws/~hmm/rswf/example/swf8-scrollpane

And I'm not limited with restrictions which you have when you use 
includes from external files - I have one file at the end.

rebol [
	type: 6
	file: %test.swf
	background: 0.0.0
	size: 260x185
]
doAction [getURL("http://box.lebeda.ws/~hmm/rswf/""_self") ]
showFrame
end

Just had to add folder with made swf file to allowed locations here: 
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04a.html

Using rebol to call mxmlc.exe and deliver it some Rebol generated 
xml gives you a Flash 9 .swf file all set to go.. kinda cool.

If I would like to use Flash components, I would do it. It's not 
difficult at all. You just have to export all the components into 
SWF file (more than 250kB) which I can import using my import-swf 
keyword in the dialect and that's it... than I could just place imported 
classes. But I don't want to do it. I would rather use my own. Yes... 
it's more difficult in the begining, but the more freedom I have 
when I want to do it how I like it to be.

I've putted together the missing functions in /core 2.7.5, taken 
from /view in the swf-in-core.r file, try this:
move to the appropriate directory, then:
do http://reboot.ch/rebol/swf/swf-on-core.r

make-swf/save/html http://box.lebeda.ws/~hmm/rswf/examples/swf8/swf8-convolution1.rswf

Oldes, where can I find the tracer.swf file that is included in this 
example?
http://box.lebeda.ws/~hmm/rswf/examples/swf8/swf8-iconlist.rswf

Three problems with them:


1) The widget engine is a hefty 12MB or so download (for widgets 
that are nothing other than HTML+CSS+Javascript+Images bundled in 
a zip file with a magic extension)

2) The download/installation process tries repeatedly to high-jack 
your browser preferences

3) The widgets look pretty ordinary compared to the OS X dashboard 
equivalents (go here, http://www.apple.com/downloads/dashboard/and 
compare the respective dictionary/thesaurus offerings)

Is there supposed to be a file called show.r? I can't find it.

Scot: Cheyenne can interface with PHP using FactCGI. A FastCGI client 
alpha implementation is currently built in Cheyenne. All you need 
is a php executable compiled with FastCGI. I've already tested several 
php apps (even big ones like eGroupware), it works well and it's 
fast ! But, the configuration options are currently hardcoded in 
Cheyenne (need to export them in config file) and there's no dynamic 
php instance management (you have to launch each php-fastcgi server 
by hand). Once these 2 feature will be integrated in Cheyenne, you'll 
be able to run easily and php application.

Graham: good idea, I already wrote REBOL code to support emoticons 
in another project. I'll add it to the blog. (Note to myself : The 
link to Carl's blog source code disapeared in our blog template file, 
I have to put it back!)

Are you using the exe version or source version ? What OS ? Any crash.log 
file found ?

Both versions act the same. Win XP Home. No crash.log file found. 
 This is what loads:

[uniserve] Async Protocol FastCGI loaded
[uniserve] Starting task-master...
[uniserve] Starting HTTPd...

For Text CGI script I get:


#!/usr/bin/rebol --cgi REBOL [ Title: "show" File: %show.r ] print 
"Content-type: text/html^/" print {Back

} print ["Script path :" system/script/path "

The encapping procedure is special for Cheyenne, it needs to be run 
in normal mode first before encapping to preprocess the source and 
generate the .cache.efs file.

OK, http://localhostworks. I have a lot to learn, as you can see. 
Thanks for helping me through this. I was just clicking on the index.html 
file in the www folder.
