The -o command-line option for %rsc.r is already there (and since 
a while). ;-)

Have you done experiments in JIT compiling yet? R3's extension/command 
model is really easy to use to implement JIT compiled functions.

Petr - for a git GUI you might want to try SmartGit - free for non 
commercial use and, IMO, the best GUI. Also, it's available for all 
platforms. I use this, tortoise and the command-line, depending on 
the context

-dlib option: it's just set the flag to produce shared library instead 
of executable.


-t option: sets a target which is just a handy way to group several 
options together (most options don't have a specific command-line 
switch).

For Git command-line users, a useful cheat sheet: 


http://jan-krueger.net/wordpress/wp-content/uploads/2007/09/git-cheat-sheet.pdf

The big win is the command dispatch model though, because it basically 
lets you get dispatch to JIT-compiled functions for free. The dispatch 
function can manage changes between execution models completely without 
R3 even noticing. Lua has similar separation, though since it doesn't 
have to support anywhere near as many datatypes it can get away with 
a stack-based interface.

Oh, the particular quality of the R3 extension dispatch model that 
makes it well-suited to JIT compiler implementation is that a command 
function contains an indirect reference to the dispatch function, 
and an index integer. When the command is called, the runtime calls 
the dispatch function and passes the integer and a marshalled stack 
frame. For a JIT compiler dispatch function, the index of the command 
can be an index into an array of function pointers or something like 
that, and the dispatch function can just pass the stack frame to 
the appropriate function, then return the results. This means that 
the hard part of JIT compiling - getting the regular runtime to call 
the created functions - is something that you essentially get for 
free with the existing command mechanism.


You could also use the dispatch function to marshall arguments into 
another runtime with a different call model. You could, for instance, 
have a dispatch function that pushes the contents of a marshalled 
stack frame onto a Lua stack and calls Lua functions. Or you could 
do something similar for LLVM functions, or ActiveScripting languages, 
or V8, or ODBC queries, or even Red's JIT.


This all depends on having a good marshalling model in the first 
place that can handle the datatypes you need to support, and it would 
also help if there was a good task-safe callback mechanism that actually 
works (R3's needs a bit of work at the moment). Still, the principle 
is sound.

It would be much better to have a real IDL for the command descriptions

Brian: I'm aware of that. The probabilty of someone porting Red to 
old MSDOS (no Unicode, no multitasking, no native TCP/IP) is very 
close to zero. If someone does it anyway, we'll adjust our targets 
ID accordingly. In the meantime, I prefer typing "-t MSDOS" rather 
than "-t Windows-Console" on command-line. Also, it's easier to remember 
for everyone, after all it's just an ID, nothing else.


If you are thinking about FreeDOS, which is probably a more likely 
target than real old MSDOS, I guess we won't have any name collision 
then. ;-)

what about calling it CMD (as is the command, cmd.exe, which you 
have to issue to open that black old console), or CON, as a "console"?

The %run-all.r script in root folder runs all the Red + Red/System 
unit tests. It does use CALL command which might need some permission 
under Win8? (just raw guessing, haven't tried Win8 yet). Can you 
try to run it using Admin priliveges?

Now Red supports 21 datatypes. In the following R3 datatype list, 
datatypes with a minus prefix are not supported in Red yet.


action -binary -bitset block char -closure -command datatype -date 
-decimal -email -end -error -event -file -frame function get-path 
get-word -gob -handle -image integer -issue -library lit-path lit-word 
logic -map -module -money native none -object op -pair -paren path 
-percent -port -rebcode refinement set-path set-word string -struct 
-tag -task -time -tuple -typeset unset -url -utype -vector word

But they tend to crash R3 a lot when the command api fail

As for /Core, /View, /Command etc, I just wonder - will there be 
any such product separation with Red? I mean - you can have big "ecosystem" 
linked via R/S, so I wonder, if there will be any packaging, or simply 
products, for certain areas, containing related libs, etc.? Or an 
environment builder, where you choose modules, or something like 
that?

The cool stuff to show-off would be - bring your Red on your SD card/USB 
stick, plug-it-in, go to its dir = show "no-instal" option, show 
some GUI dialect, press a button, generate android app, and with 
one command or a dialect, push it to Google play. Then I can send 
you my friends short/long description, how long it took him to get 
his app there, downloading and installing all the JAVA crap and all 
dependencies ...

An altenative for preprocessor command could be
.if
(It starts in column 1 doesn't it?)

On the other hand isn;t it possible to get the meaning from the context? 
#if #define etc could be preversed preprocessor words?
(or I am on a complete other level again this time)

Congratulations: the rhythm of changes in Red is just fast!

I scripted a little command that I run from time to time, just to 
see how both Rebol3 and Red are going:
cd ~/dev/Red/ && git pull && cd && cd dev/r3/ && git pull

And I can see through gitk that the rythm of Red's work is just amazing. 
Courage!

What command line are you using for testing #381?

or xnview command line - then you just need a CALL ....

It's best to use the MSDOS folder. The Windows folder is less complete 
and compiled as GUI apps, so no command line output

Did a quick profile of play-sdl-wav.exe sample.wav into dependancy 
walker and ran it and can hear the sample play.  It doesnt' play 
however when invoked directly from the command line.

Nice, we're making progress. So still not direct from the command 
line?

Yes, even though drag and drop should be the same as starting with 
a command line parameter

You can also give console-pro a file or URL to DO on the operating 
system command line

Endo, you could even make it a webservice that could be used with 
a simple WGET call from a command-line. ;-)

Not sure what mode of compiling Red/System you are thinking about, 
but if you compile via rsc.r, you can tell it where to write the 
binary by passing a `-o` command-line option.

I can compile a Red/System extension with the R3 bridge and load 
it into R3. However, only two of the COMMAND examples work:

open a command prompt, change to the directory the .class is stored 
in, and run `java JNIdemo`

How about having the compilers recognise a "Type: library" field 
in the Red [] and Red/System [] headers, so you don't have to add 
the -dlib parameter to the command line?

Updated our R3 version. Changes:


- no longer links libstdc++ dynamically but statically. You get an 
error that libstdc++-6.dll is missing from your computer.

- changed startup procedure to support correct stdio redirection 
in console mode (used if you start R3 with a command line argument, 
else GUI mode)

My 6502 emulator in Red/System now takes the name of a ROM file as 
a command line parameter. It can load any ROM that's a multiple of 
2 KB in size:

I made a version of the Red interpreter console for other platforms 
than Windows. It runs on systems that have the ReadLine library. 
It uses both the libreadline and libhistory libraries, so it provides 
command line editing and history recall

New r3-view.exe published. Fixes the problem, that the graphics subsystem 
wasn't initialized when command line arguments are given. So, now 
it behaves as before and should give correct STDIO.

You can give arbitrary SQL instructions to an arbitrary SQLite database 
from the command line

Everything around it is done by Red, such as processing the command 
line arguments, opening and closing the database, injecting the SQL 
and processing status reports

I extended the Red text editor to support a program argument, for 
loading a text source from the command line:

It's best to start it from a command line to get any diagnostic output

I wrote an example of a browser for Internet sites written in Red. 
The source code is here:


http://red.esperconsultancy.nl/Red-GTK/doc/trunk/examples/GTK-browser.red


The usage model is like a web browser. You point it to network or 
local file links, in an address bar or as a command line parameter, 
and it displays them in the same content area in one window. A Red 
page can contain links that make the browser go to another page.


You can create and roll out Red sites just like websites. We are 
hosting the first Redsite here:

http://red.esperconsultancy.nl/index.red

You should be able to compile the test driver with the latest Red/System 
development version, following the normal build procedure but adding 
the following parameter to the Red/System compiler command line:

rsc.r -t WinDRV driver.reds


This effectively replaces a makefile build script that the WDK uses 
that is almost 12,000 lines.


By the way, the WDK is unable to work in a path that contains spaces, 
so for example on older Windows versions such as XP, you can't develop 
drivers in your home directory, because your home path always contains 
spaces. I think Red will now allow you to do that.

Remember Doc's instructions for running command line programs on 
Android:

http://www.red-lang.org/2011/12/arm-support-released.html

I have extended the Red/System null driver for the Windows kernel 
into a null mini-filter driver. It now registers itself as a mini-filter 
and imports functions not only from the kernel, but also from the 
FilterManager driver, so it is now in a hierarchy of drivers. It 
now responds to a stop command, so you can stop running the driver 
like this:

sc stop hello-Red


I will set up a new repository later to publish the Windows kernel 
and FilterManager bindings and examples.

Some additional notes:

-you can run the demo on Saphir / R3 Andoid just by typing DEMO in 
the console

-the Linux, OSX-PPC and OSX-Intel "View" binaries needs 32-bit version 
of freetype2 library (also included in the specific build folders)

-the Linux, OSX-PPC and OSX-Intel "View" binaries are currently able 
to render DRAW dialect to image! (using the DRAW command). We'll 
be working to get full graphics support on the metioned platforms 
in the near future.

You need to update your repository from your local command line or 
Git GUI

(Replying to AdrianS in Announce) R3's extension mechanism is designed 
to make it more possible to make and compile extensions that will 
continue to work even when R3 is updated. Even with the source open, 
that is still a value. The command dispatch model is also really 
useful for implementing native dialects and JIT compilers. The marshalling 
mechanism is also reasonably fast by FFI standards. It could, however, 
use better marshallers for series, and more datatype coverage.

To get Unicode output on Windows, you need to switch the command 
prompt to Consolas font

No installation is needed. The libraries are simply there and are 
used from that directory. The graphical programs can simply be clicked 
on (although they provide extra output in the command line)

Sqlab, I have no problem loading files from the command line into

@NickA: About enhanced r3 chat, have a look to %wchat.r in the %OpenMe/ 
folder of this Altme world.

Basically its %chat.r but it act as a proxy between the Devbase server 
and the browser. The goal is that the browser replace the CLI interface 
: not typing command in CLI but cliking link in the browser.

Its just a start. There is some work to do to handle POST request 
and then allow posting. + enhancing HTML presentation.

Kaj: it works now from command-line on Win7 and an icon for an hidden 
window appears in the task bar.

Thank you all for addressing my concerns and for your answers about 
my first coding question.


Ahh.. rejoin. Reading up on it makes me better understand how some 
things are to be done in Rebol.

 Continuing to the final goal...


I have to extract an email address from a GET transfer. The methoed 
of sending the info to me is completely out of my control. An email 
address will be entered into a form on a website not controled by 
me. GET methoed will send the data to my script. The people who created 
the form on the external site advised that they label the email address 
as "trnEmailAddress".


 So now I want to see if I am correct in thinking how to extract and 
 use the email address. Will using the decode a cgi form command (I 
 know they are not commands in the tradiational sense)  work. How 
 does it work, does it create variables out of the GET (or Post when 
 using Post, but I am forced to recieve the info via GET) stream?


The GET stream in my case will include "&trnEmailAddress=person%40example%2Ecom. 
So can I do this?

decode-cgi system/options/cgi/query-string

send trnEmailAddress "Thank you. Rest of message." 

Thanks for your help.

Graham: Thanks. That makes sense out of something someone else told 
me. I thought the information was contradicting what you guys said 
earlier, it just means I misunderstood the order of things. The modiffer 
after the slash is closer to making a new command than it is an agrument 
than I had envisioned. The fact that random is part of both made 
me think they could be done together. Thank you for catching that 
I did not know that detail.


 Next part of myscrip enters something into a database. The server 
 will have an mySQL database installed. It is possible that alternative 
 could be used, but knowing for sure I have at no extra charge this 
 options means I am starting with this option.


 So I found a MySQL Driver for REBOL from here: http://softinnov.org/rebol/mysql.shtml


 I am following the instructions that came with the download. Is there 
 anything I should know. Maybe it is not the driver people use because 
 there are better ones. Maybe the author kills kittens on the weekend 
 and it is consider bad form to use it. Maybe it is harder than it 
 looks. Basically, please just tell me if there is general info about 
 it I should know that is not obvious. Thanks.


Hey, someone else is asking questions? i thought this was all about 
me! :-) :-)

odbc drivers for windows can only be used with the rebol/view, the 
gui build, unless you paid for a rebol/command sdk

Rebolek - thanks, I forgot about it. I needed it only once in the 
past, and so I used iconv command line tool  via CALL ....

I have a problem renaming files. rename does not change the filename 
on MacOSx. In the terminal it is no problem but in my script the 
filenames are not changed.

            fileo: to-file rejoin [what-dir add-suffix naam-oud-z-ext extensie]
            filen: to-file add-suffix naam-oud-z-ext extensie
            rename fileo filen

I have tested with probe that the types are ok and with the resulting 
values for fileo and filen the rename command worked like a charm. 
Any more ideas what is happening and how to debug this further? Thanks.

Petr, if you need a quick command line codepage converter program, 
try txtcnv32 here: http://www.ltr-data.se/files/txtcnv32.zip

It lets you specify code pages by number. The documentation of the 
code page numbers is here:

Might be a bug where encapped REBOL tries to consume its own command-line 
options (while it shouldn't).

It looks like. I thought that it confusing with REBOL's own command-line 
parameters but it happens only for some of them not for all. So no 
chance to use *some* parameters.

Aha PRINT and PROBE doesn't work in encapped executable if command-line 
parameter includes a "c" character.

Any "c" character? I guess then that I was very lucky with Cheyenne: 
http://cheyenne-server.org/wiki/Main/Command
:-)

BrianH: Yes I realized that at least one word is required.

sqlab: I encap a script and run the executable, so I should able 
to use any command line parameter. And I don't encap with cgi option. 
Also -w parameter has no such a problem (which is "no-window option 
for REBOL)

Anything that include "c" char prevents to print/probe to the console.

On the other hand it doesn't prevent opening console window. I see 
"** Press enter to quit" message when program HALTed but PRINTs don't 
output anything.

I must admit that if you can receive events in the host, you can 
just execute a code string within the root ( just like if one enters 
a command in the prompt).   It worked very well for interfacing with 
GLUT ... I had just built a little pseudo event system which I called 
from within the glut callback and it was fast enough to handle all 
events in real-time.

see usage in the command level

rebol.exe --secure allow in the link string should work wit most 
versions

Thanks for the welcome back message.
 

 I left off asking about the mySQL driver. So I want to insert into 
 a database a random number the code already generated and associate 
 it with an email address that was provided by a CGI form. Have yet 
 to create this in the real world but for now let us assume I will 
 call the database "customers". The people who process the credit 
 card and collect the email address advised me that the address will 
 be labelled "trnEmailAddress".


 After finding the mySQL driver Here is what I figured out using placeholders 
 for things like password, etc. Would appreicate knowing if this is 
 correct.

; Loads MySQL driver
do %mysql-driver/mysql-protocol.r
; Opens connection to MySQL server
db: open mysql://[[user][:pass]@]host[:port]/database


; Send query to database server. Enters random number from above. 
customers is probably the name of the database I will create

insert db ["INSERT INTO customers VALUES (?,?)" "trnEmailAddress" 
"token"]



 Next I need to insert an existing PDF file (an e-book) into a directory 
 created by the script. The directory will be named after a random 
 number that was earlier generated by the script. I am astounded that 
 I can not find the command to copy a file. So the variable assigned 
 to this random number is called "token".

 So I have the following.

make-dir %token/


 How do I copy a file into this new directory? Also, is that the corecct 
 way to make a directory?

I suppose the CASE command would be better

And for the case of q and quit, and maybe others, you want to see 
if they command is in a set of commands you want to process in a 
special way, correct?

That is, you want to see if you FIND the command in a set of known 
commands and act accordingly.

not really, it's just a quick shortcut to allow any REBOL command 
to be performed while it is in a script that is already executing.
...doing stuff...

stopping here to accept various rebol commands and looping until 
finished
...doing the rest of the script

Right, so you ask for the command, see if it's a command to exit 
your loop (q or quit) and DO it if not, correct?

Although, the way I have it, it should do the command no matter what 
is entered

Actually, it is.  I want it to do ANY rebol command.

Any command except q or quit, which should break your loop, correct?

Just FYI: workaround the bug:

forever	[
	do script: ask	[~ " REBOL COMMAND? "]	; do the entered command
	if script = "q"		[break]
	if script = "quit"	[break]	
	]

So, coming back to the original question... :-) Rather than doing 
"script =" for every command, you could say "if find ["quit" "q"] 
cmd [break]", so it's easier to check multiple commands, aliases, 
etc. e.g., what about HALT?

i.e., get the command, check if it's special and, if not, DO it.

In R3, youi can also use the QUOTE command:

>> parse [1] [quote 1] 
== true

Yup. You should see what they have in store for SQL Server 2012. 
It can be run on a fully command line OS, managed remotely entirely 
through PowerShell scripting. And you can do PowerShell scripting 
of MS servers from Linux clients too, reportedly.

If you want to get the column metadata about a table, use the 'columns 
command:
- For R2: http://www.rebol.com/docs/database.html#section-27

- For R3: http://www.diefettenjahresindvorbei.de/odbc/odbc-docs.html#section-3.8
 though there's an error in the docs, so use 'columns instead of 
'tables

The docs for what the 'columns command returns are at the link for 
the R2 docs above.

Back in 2001 I created an intranet site for a local celebrity by 
making the database tables, then having R2 use the 'columns command 
to generate column lists that were used to autogenerate the server-side 
pages for the intranet. All it took was one function call per table 
to generate the whole site. Restyling the site just meant editing 
the HTML template in the function (this was before CSS was practical).

and, try to connect from a remote PC using mysql command-line tool.

I still think that it is because your mysql server does not accept 
connections except localhost.

Did you try to connect your database using mysql command-line tools? 
or MySQL Workbench from a remote PC?

command for comparing values in mysql database ????

if  user wants insert values to table and it should save in database 
,what is the command for that ???

this command is correct ???  :  insert db ["insert into data1 values 
(?)" myfields name]

You first check that the value is acceptable for what can be expected. 
This is to prevent SQL injections and other malicious input from 
hackers/innocent users and monkeys using your application. Than you 
insert a SQL command to insert or update  the mysql database just 
like you did when you did with your select statement before.

 mijnquery: "INSERT INTO cms_artikel (titel, tagregel, sectie, toegevoegd, 
 artikel_tekst) VALUES ('"

 mijnquery: append mijnquery rejoin [titel "', '" tagregel "', '" 
 desectie "', '" toegevoegd "', '" artikel-tekst "')"]
 insert db mijnquery

 The names after INTO are the fieldnames of the table cms_artikel 
 the ones after VALUES are the REBOL variables that get replaced by 
 their values

can you post your insert command here?

They can be started from the command line. Although this is Syllable 
Desktop, for details it may be helpful to consult the Syllable Server 
manual, towards the end:

What does the GrUB root() command in menu.lst say?

I do like a lot of the REBOL docs, which took time and effort to 
create. Wikis are good for reference information. I agree with Arnold 
that good examples are important. I'll add that giving people a starting 
point is helpful. For example, have example scripts for different 
types of apps or features; CGI, pipe and filter, command line handling, 
etc.


I also think format fragmentation is bad. REBOL's docs are fragmented, 
which makes it hard to know the best place to put something. Being 
able to share data, or have a common doc db that can be rendered 
in different ways, would be great.

If a command in RED and Rebol share the same name, but behave diferently, 
these differences should be clearly shown or explained

About Git, it is not that complicated, you just need to learn a few 
(2-3) usage patterns to be able to install/update your local repo 
and submit a change. Maybe someone could provide a simple Red-repo-oriented 
tutorial using TortoiseGit and command-lines for those basic usage 
patterns?

Is like that says: 
.
 is not a command

Watch out though, all mezzanine control structures that execute code 
blocks passed as parameters are be subject to http://issue.cc/r3/539
so they would need to be native until we have a solution to that. 
And not a command, because the necessary internal stuff isn't exported 
(purposely), so you couldn't do REWORD as a command.

q should not be set by default.  anyone can add shortcuts for such 
stuff easily in their %user.r   

maybe we could even add a function which define all the "command-line" 
shortcuts, thus allowing them to be undefined by default.

MaxV: "This way you have to write very long commands to achieve the 
most simple tasks (show mybuttob/gob ... mybutton/gob/size). Is it 
just my impression?"


My guess is you are not using R3GUI correctly. If you are using the 
current included R3GUI styles you shouldn't be forced to write any 
SHOW commands at all(the SHOW command is considered 'internal' in 
R3GUI and shouldn't be used anyway). Just use the SET-FACE/GET-FACE 
api to make changes to the specific style.

In worst case (usually when some ON-GET/ON-SET handler is unfinished/incomplete 
in some style) you can either try to enhance/fix that style part 
or

if this is too difficult for you you can try to use SHOW-NOW <face> 
to really force 'show' on the specific element.

...we wouldn't need of 2 standard versions of Rebol (core and view)...

That would be great, I remember that it was very confusing to me 
to have Core, Base, View, Face, Command etc.

But of course, it's not an easy task. One must be careful to make 
it right.. all the draw command batching, texture packing etc.

Same reason I do not develop for Red, because Github does not support 
Snow Leopard any more, and my Mac cannot go further and I do not 
buy a new mac for  github. And the command line I consider too much 
trouble to learn.
