AltME groups: search

Having a little trouble getting AltME to work in Ubuntu Breezy.  
I'll need to go back and make a note of specifics, but double-clicking 
the icon does nothing (rwe all checked), and running from the terminal 
gives me an error.

Ah, I need to try the bundle steps for AltME.  I'm still launching 
from a terminal session, though I do have one open typically anyway.

Isn't it dependent on type of terminal you are using?

Got a few error message in the terminal session that AltME always 
opens (and leaves open after quitting.):


altme(6254,0xa038c620) malloc: *** mmap(size=3021340672) failed (error 
code=12)
*** error: can't allocate region
*** set a breakpoint in 
malloc_error_break to debug

anyone knows whats this? i had altme open on my intel mac for a few 
weeks and this is what it was spitting onto the terminal. there was 
interesting glicth happening at the same time: my clicks were interpreted 
with some offset.

volker, well I didn't get any trouble under Linux with GNUstep's 
Terminal.app so it may be a terminal issue

If I ssh to a linux box from the terminal where I saw the problem 
originally, there is no problem either

Linux 1.3 Beta -> Something is realy from with the terminal adjustement 
during view/console and after stopping view. The Console gets messed 
up like it has the wrong TermInfo values?  During a call/shell execution 
from the view/console also the console from Rebol/view is mixing 
up the call/shell "vi" ????????

Does anyone know if REBOL runs on Windows CE.NET 4.2 ? I'd need to 
use REBOL on that platform but I don't have access to a CE.NET terminal 
and can't use an emulator because there's no REBOL WinCE x86 binary.

the BCC header field is a field used by mail clients to let users 
type addresses that will *not* be included in the header. it is, 
basically, a user interface. back at the time mail clients did not 
have a gui, and just processed mail from a file or by letting you 
type them on the terminal

(hopefully) quick question - I know you can use prin "^(page)" (or 
prin "^L") to clear the current terminal window - is there something 
just as simple to clear just the current line?  Or move the cursor 
back to the beginning of the line?

Sunanda;  You should have mentioned loading the Terminal User Interface 
and all the funky VT100 escape sequences and the...
Just kidding :)

It's always felt consistent to me - the context is being evaluated, 
and lit-word!s reduce to word!s, word!s reduce to functions and values, 
while other datatypes reduce to themselves:
>> X: [{One} 'Two]
== ["One" 'Two]
>> ? X/1 ? X/2
X/1 is a string of value: "One"
X/2 is a lit-word of value: 'Two

>> X: reduce X   ;Here is where typing it in on the terminal evaluates 
to
== ["One" Two]
>> ? X/1 ? X/2
X/1 is a string of value: "One"
X/2 is a word of value: Two
>> X: reduce X
** Script Error: Two has no value
** Near: Two

...and the reasoning behind lit-word!/word! acting differently is 
that those are special datatypes where other values can be bound 
to them

what do you mean Doc ? It has been always like that.

with /part you can specify a length or a terminal pointer to the 
serie.
What's wrong with that ?

are you sure View didn't just pop up its security requestor behind 
the terminal so you couldn't see it?

Sunanda: given that R2 uses the host current code page, I think the 
best way would be for the user to convert the script after downloading 
it. On Linux or Mac for eg, UTF-8 is perfect for Core scripts as 
the terminal is UTF-8. On Windows or for View scripts, you'll get 
the host code page displayed anyway, so the user has to do the conversion. 
A tool to do that automatically would be nice (I have the code, it 
will be released soon, but you may need to wait a couple weeks more).

Or basically Terminal Services.

Here's my problem, from a new terminal session:


>> view layout [box 120x70 effect [draw [pen black polygon 0x0 119x0 
119x69 0x69]]]

>> view layout [box 120x70 effect [draw [pen black green polygon 
0x0 119x0 119x69 0x69]]]
Segmentation fault (core dumped)


..which should work fine, according to this Draw documentation:  
http://www.rebol.com/docs/draw.html#sect0.9.1.

the "console" on Mac and Linux is just a terminal (OS provided), 
and they are usually UTF-8. That has nothing to do with View.

BT, the codes you see at the console are ANSI escape codes, and that 
has nothing to do with what you get from view, eg. the "home" key 
sends the 'home word in View but an escape sequence on the terminal.

We might move to beyond "I'm new" here, but we have a slighty different 
understanding, I think.

none is always a word

There is a possible trap here for the new one. This is output from 
my terminal:

>> blk
== [none]


Is that "none"-word a word in the REBOL understanding of a word? 
It depends on, how I made it. Did I write:

>> blk: [none]
== [none]

or did I write:

>> blk: []
== []
>> append blk none
== [none]


For the programmer being new to REBOL, it may be hard to see the 
difference. And the sentence "none is always a word" may only apply 
to the situation, where values are being fed into REBOL, not when 
I write:

>> blk
== [none]

Or what?

Having trouble with the "switch" function.
I'm entering the following at the REBOL terminal:
>> time: 14:00
== 14:00
>> switch/default time [
[    8:00 [send [wendy-:-domain-:-com] "Hey, get up!"]
[    12:30 [[cindy-:-dom-:-dom] "Joinme for lunch?"]
[    16:00 [send [group-:-every-:-dom] "Dinner anyone?"]
[    ]

For my trouble, I get: :)

** Script Error: switch is missing its case argument
** Near: switch/default time [
    8:00 [send [wendy-:-domain-:-com] "Hey, get up!"] 
    12:30 [[cindy-:-dom-:-dom] "Joinme for lunch?"] 
  ...


Am I using the REBOL terminal incorrectly? I'm using rebcore v 2.7.8

I just adopted a new notation standard for parse rules... the goal 
is to make rules a bit more verbose as to the type of each rule token... 
I find this reads well in any direction, since we encouter the "=" 
character when reading from left to right or right to left... and 
parse rules often have to be read from right to left.

example:

=terminal=: [

 =quote= copy terminal to =quote= skip (print ["found terminal: " 
 terminal])
]


on very large rules, and with the syntax highlighting in my editor 
making the "=" signs very distinct, I can instantly detect what parts 
of my rules are other rules or character patterns... it also helps 
out in the declarations... I see when blocks are intended to be used 
as rules quite instantly where ever they are in my code.


in my current little parser, I find I can edit my rules almost twice 
as fast and loose MUCH less time scanning my blocks to find the rule 
tokens, and switching them around.

wonder what you guys think about it...

(That question mark not visible in the terminal, showed up when I 
pasted here)

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

I bought the burner to use from my Atari 8-bit. There was a PC program 
for it, but I could use it from the Atari in a sort of terminal mode

On the desktop, you can open the Disks folder, and then rightclick 
in the background to get a mount dialog and choose an available volume. 
Those will be mounted in the root. Manually in the terminal, you 
could mount volumes anywhere with the mount and unmount commands

Graham, do you mean the terminal doesn't open?

Double click on the terminal icon on the desktop .. nothing happens.

the terminal now opens but leaves a trial all over the browser as 
I move the terminal window around ...so i guess the browser is busy

terminal prompts don't appear.

I thought you had a terminal now?

But a virtual terminal pty0 is not what we want --- we need Ethernet 
card instead of pty. And to specify an Ethernet card, LFS instructions 
use "plugin rp-pppoe.so eth0"

pty, pseudo tty (terminal enulator).

I do get an error with Core where it stops responding after loading 
in a terminal. No prompt or error appears. This doesn't happen with 
View.

robert,  I would ask your hosting company if they can give you access 
to the terminal server  (so that you ssh there and then you can reboot 
and see boot messages as if you were on a local terminal - note you 
might have to configure the server first

if you have access to the terminal server I can send you info on 
how to configure it so that you get the boot messages

Ok, thanks for the comments. What's this terminal-server stuff? Is 
this a special console I connect too?

the terminal server is used by the hosting company to access multiple 
servers consoles without having physical consoles. When they reboot 
a machine the can get the bios boot messages because there is a console 
cable to the terminal server and they normally access the terminal 
server via ssh

Is there any specific need to make View 1.3.50 running under Linux:
- It runs right while clicking the icon
- it fails to run from a terminal:
	./rebol
	** User Error: REBOL: Cannot connect to X server
	** Near: size-text self

Terminal doesn't respond to double click.

Thanks Kaj .... I did manage to get a console to work under 6.10 
but cant remember how I did it (I think it was by running rebol from 
the terminal).

if you make a shortcut, you should be able to select "run from terminal" 
(exact way depends on if you're on Ubuntu or Kubuntu).

I remember that some time ago, if I would double click on the icon 
I would get a prompt wih the following options: "Run in Terminal", 
"Display", "Run". that's  what I'd like to see again

I'm relatively new to Linux in general, so this may be a simple question: 
When running REBOL in the terminal, how can I enable the <HOME>, 
<END>, and <DEL> keys? Right now they just print out "OH," "OF," 
and "[3~," respectively. I'm running Ubuntu 6.06 Dapper with Gnome.

James, I guess, you're interested in the keys in View. This will 
tell you the actual key in view:


view layout [b: box red feel [engage: func [face action event] [probe 
reduce ["box" action event/key]]] do [focus b]]


Run the code, activate the view window and press the keys. You can 
see the key values in the terminal.

If you start from a terminal session and use $ rebol    ( or whatever 
command)  and then hit the console, does the REBOL banner show up 
in the terminal?  That's where it should be.  No seperate "windows" 
console required for GNU/Linux.  If there is no banner, then puppylinux 
may be pooched.

Have you tried starting rebol from a terminal program?

If you work in a terminal emulator in an X window, you can just start 
graphical apps from the command line

What console is he running?  Under Konsole the list of encodings 
is overwhelming.  (From the Settings menu).

If it's xterm, then ... I dunno, but regardless, if it is xterm or 
other, drop a note and we'll track down an appropriate place to tweak 
the default encoding used by his REBOL console (whatever terminal 
he uses) session.


It might be easier (some gui menu), but it could well look something 
like

XTerm*locale: true

XTerm*font:             -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1

in an X config file


From the root text console for REBOL/Core, we'd have to look into 
that as well; been there, kinda done that, too many details, forget 
all details, but keep foggy clue where to start looking ...  :)

does he get the same even when using the hexdump command? could it 
be that that character "enables" something? the terminal will process 
the escape sequence but rebol will not.

The launch environments are different in that the shebang path is 
used by the shell to know what to do with the script. You can also 
run a REBOL script in the linux terminal with: rebol -qs script.r 
and it will be the same script as under Windows. It might look a 
little ugly, but you could wrap your windows REBOL scripts in a shebang 
script.

Another option is dtach, which allows you to detach from and reattach 
to a terminal session even if you completely disconnect from the 
machine in the interim.

Don't know anything about the server questions, but Ubuntu by default 
doesn't have a root password - use "sudo su" to get a root terminal, 
then passwd if you want to give root a password

most programs do not check that the file name is valid utf-8. normally, 
you're using a utf-8 terminal so there is no way you can type an 
invalid filename. but you can easily create one using rebol for eg. 
or using escape sequences in the shell and so on

(You are right about terminal signalling, but of course this is not 
the only thing this proxy port is useful for.)

Yeah I started looking at the code. It's a bit hard to debug for 
me though. The error doesn't give any line number, it just says "near 
show main". I searched for "show main" and found three occurances 
in the source. I'm completely new to REBOL so going through everything 
in the code would take me quite some time without being able to narrow 
it down first because everything looks alien to me and I have to 
look it up to see if something in the script looks wrong. Is there 
some good tutorial available on debugging REBOL code? Or is there 
some trick to find out the last line that was executed? I do have 
access to the terminal at that point, the view is frozen but the 
terminal still accepts commands.

Ubuntu 9.10 is quite good. I've only had to visit the terminal a 
couple of times to get SMB filesharing working since I first booted 
it 5 minutes ago and only one cryptic error message appeared.

Bolek: REBOL is not going to start a terminal program for you. However, 
if you have a icon, you can usually open the icon properties and 
tell the "desktop" (XFCE in your case) to start the program inside 
a terminal (ie. it will start a terminal and then the program inside 
it).

help!   how do I get rebol on linux to start without trying to open 
a setup window?
I get:

** User Error: Bad face in screen pane!
** Near: size-text self


everytime I start any /view capable rebol from a remote terminal 
(I'm not in a desktop).   


I need the view capabilities (to-image, draw), but not the windowing.

Just installed Zorin 4 (ubuntu based) and i'm having trouble getting 
R3 running. I assume I run it from the terminal  but I get "commnad 
not found" error. Anyone know what I'm not doing?

Just redid my netbook with Ubuntu Netbook 10.10, and it works much 
better than in did with WinXP. Had to partition manually as the tweak 
to make the installer SSD friendly is still a proposal. R2 and R3 
work, though (as someone used to the Windows versions) I am having 
trouble with the console not opening a terminal when prompted to. 
I guess the button in the R2 View desktop doesn't work. Time to figure 
out the application shortcut creation method for this distro.

Regarding the console, fire up REBOL directly from a terminal and 
you'll be fine.

Creating a "Application in Terminal" type launcher should do the 
trick.

If the Unity launcher (at least I think that's how the launchbar 
in the netbook thing is called) still uses .desktop files, it's probably 
only a matter of finding the associated .desktop file and modifying 
it to use Terminal=true

New editor that support REBOL  colored syntax file. This sofware 
is SCITE 1.66 for linux and windows by default REBOL support is not 
activated. edit /usr/share/scite/ScitEGlobal.properties file ( MenuBar 
Options >  Open Global options File) search the line "#import rebol.porperties" 
and remove "#". Save changes (SCITE must be launched from a root 
terminal.) then edit /usr/src/rebol.properties file. Go to the last 
line of this file and set the proper path to your predered rebol 
VM version in the  command.go.($file.patterns.rebol)=....  Save the 
rebol.properties file ( this file can be located from Menubar Options>Edit 
properties>open rebol.properties). Once you make all those changes 
you are able to see rebol color syntax for your beloved rebol scripts.

the scripts are launched into the rebol VM hitting F5 key in SCITE. 
You will notice that the color syntaxe is very more advanced than 
the Crimson Editor one. And you have the  ability to hide the functions/objects 
inside code to make easier to read the script code.

Well this is the concret sign that REBOL  is being more and more 
considered in computing world. This is a good thing and a good reward 
for RT hard work.

well, drop list is not good example of how to use gui via keyboard, 
I do agree :-) our users are not typical users maybe, as they come 
from terminal SAP R2historically, where there was no mouse :-)

Is there a way to make the scroll automatically go down when adding 
text to an area?  I have an area I'm using as a status terminal window 
and I can't see the feedback until the task is done because the scroll 
stays at the top.

Then there are the slow-as-molasses industries that replaced 3270 
with PC's just in time to discover 'thin client' as the 'new terminal'.

Diskless-Network-PC? Give me 6 months of high fashion and the 'new 
black' any day.  Client app? Pass the X-server wlll ya ....  ;-)

How hard would it be to write a LAYOUT function that will transform 
the RebGUI layout into a HTML page?

 Dynamic or static conversion? I think it's possible to map most VID/RebGUI 
 styles/widgets to CSS and HTML with Javascript required for a few 
 of the more complex widgets; so reproducing simple layout forms online 
 is trivial, more complex apps with tab-panels, etc a whole lot harder.


This reminds me of some of the R&D work I was doing with IBM back 
in the early 90's. Layouts were IODEFs (Input/Output definitions) 
where you hooked a data source (e.g. DB, Terminal, Webpage) to an 
output target (e.g. Screen, printer, Webpage) with zero application/logic 
changes. The entire app was stored in a code repository across a 
couple of simpe DB2 tables. Anyway, I digress.

Serious bug introduced in build 218 or even 217.

Drop-list and edit-list widgets produce past-end error on list selection. 
Tested tour.r, RebDOC.r and in terminal. Nothing works.

I just booked my flight to Milan. Here is my arrival data:
29-09-2005 18:25 in  Milan, Malpensa [MXP] TERMINAL 1


I have rented a car as well. So if someone is arriving around the 
same time let me know and we can drive together.

which terminal program do you use?

The standard Terminal incl. in MacOSX

the fact that it uses http, html and js... doesn't make it different 
from any other stupid dumb terminal.

What do you mean by "smart client"? Efika is not only a terminal. 
It can have full OS you can install. It is just that they use something 
like VNC/Citrix aproach, to get you SW you don't have installed physically 
on the machine itself ...

on OSX, it would be nice to have native access to file metadata (what 
"mdls filename" return from the terminal in Tiger) with something 
like info?/all or info?/meta or info?/metadata returning an object 
with the metadata.

You can use terminal escape codes for that, or usually, you use a 
library such as Curses or S-Lang

Question on alternate UI options, specifically ChUI (terminal style) 
or mobile options would be of interest to me.  Is anything planned 
or expected that would apply to those areas of UI implementation?

My friend Abe challenged me to write a simple recursive fibonacci 
sequence and on the 46th iteration the program quits because rebol 
can't do that calculation. I tried it on Linux rebview and rebol/core 
and on windows vista rebview even without running my script. The 
strangest thing is that rebol can add much larger numbers, but just 
not these. Does that make any sense? try the equation in a rebol 
terminal yourself and see what I'm talking about. Very strange.

I get a crash immediately. Do you start it from terminal or Finder?

I start from terminal

as to %user.r - my only use for it is so that certain functions I've 
defined that I use a lot (pad, time, fold, Logfile object, etc) are 
automatically loaded in any script I want them in, as well as a terminal 
session.

I am trying to think through this as a "clade" and not a fixed "hierarchy" 
... as in every case of c2.com as a "terminal" tag there is a common 
"phylogenic" ancestor in "smalltalk" or "wiki"      Tagging is usally 
seen as in conflict with hierarchical ontoly and I am trying to get 
my head around this in looking at REBOL versus ICON to parse thses 
cl1p.net paths if I opt to go with them.   Gabriele last looked at 
some of my odd notions here ... they come from working in a PROLOG 
variant ...

A server-side scripting language which cannot handle literal strings 
- and especially one that claims to be Unicode - has to be excluded 
from consideration for templating web content which is expressed 
in any other langauge which uses curly braces.  I told BrianH that 
the red flag here should be Tcl as Rebol shares this with Tcl.  Literal 
string are literal strings.  Period.  No if's and's or "that might 
be my curly brace in there" ...  Unless you dream of a Rebol-only 
world - and that fantasy should have passed some years back.    This 
falls under the heading of folly - a topic too often neglected.  
Folly in a meritocracy usually requires some individual to speak 
up.  But the folly of meritocracies is that  to be heard taht individual 
would already have to be playing within those constraints.  We see 
this in schools which graduate top people distinguished for inidividual 
effort who then do not fit well into teams.  They did group work 
in college by being the one who saved the group from failure by ... 
their individual effort.  For me this will be what makes or breaks 
my involvement with REBOL.  I could not wait for REBOL4 and hope 
for change then by getting into the merit circle.  My outside voice 
would have to be heard before it is too late. Tcl as the do-all is 
folly.  As nuch as I admire OOTcl, the XOTcl IDE and Expect.  I cannot 
use Tcl with "balanced brace" foolishness.  Of course if we all adopt 
XML and abandon scripting in non-XML languages ... So  We have comment 
{  }  and that was a mistake: it should have been symmetrical as 
in c{ comment here as literal with } or whatever }c   And that is 
water under the bridge.  We cannot be UNICODE and claim that  we 
must escape a certain pair  of characters if ithey are in a literal 
string.  That is silly. Ludicrous. Folly.  A literal string is a 
data value where you do not get to peek.  Imagine a proxy object 
that said: "I will be your proxy only if you promise that when the 
real object appears it does not contain [ folly happens here ] " 
  Many forms of "catch-22" in the world of beaurocratic regulation 
have a similar pattern.  I am no expert on unintended consequences, 
but requiring that some pair of characters be escaped in otherwise 
literal content has consequences for TEMPLATE value TEMPLATE  There 
should be a lesson there: some markup must be arbitrary and the choice 
will matter.  { and } are the wrong choice.  At least the terminal 
markup must be "sacrificed (it will always have to be escaped so 
pick carefully.   [{ is a bad combo for JSON so #[{ looks worrisome 
to me.  I propose lit |ls# and_content_then  #ls|    Someone shoots 
that down and we inch towards a suitable result.  Not perfect.  But 
usable.  { and } are not useable in the real world on the server-side 
if rebol is to play a role with other languages.  Play nice.  Please.

I think I'll have to rethink this. I've done it mostly like a traditional 
terminal, but this is clearly not very stable.

Running R3 from the Mac terminal the output from the print function 
is definitely utf-8 encoded.

as for Console2 - but that is gfx console, no? Will it work on terminal 
set-up?

Previously, I also haven't been able to separate "launched" versions 
of Rebol from the same terminal session. However, after a bit of 
googling I've worked out a way that seems to work using Ruby:
 
Macintosh:Rebol3 peter$ irb

>> require 'pty'

=> true

>> PTY.spawn("./rebol -q pong-server.r"
)
=> [#<File:/dev/ttys005>, #<File:/dev/ttys005>, 1437]
>>


Process 1437 was running in the list of processes and control was 
returned to the console session.

I'm still getting

:) thanks. interesting.

i was doing DOS, TurboVision, then tried Win3.0. used Turbo Pascal 
in 2 dos windows under Win3.1, programmed serial equipement with 
Delphi 1.0 under Win95, but then i just fell in love w the fvwm2 
theme of icewm and the big virtual desktop which even worked on trident 
8900 isa cards, using suse linux. i was forced using windows until 
the xp version and i even saw delphi 4.0.

no windows interface can compete with icewm with autofocus and saying 
this as someone who still can handle windows without a mouse faster 
than anyone else i know.

i found vista and win7 particularly disgusting. those dim windows 
w huge decorations just make me annoyed.
im the fullscreen terminal window in black&green kinda guy :)

i want console in web browsers too. i think lisp machines were great 
examples that how the character based interface can benefit from 
graphical capabilities.

plan9's acme is also a nice example; although i never had the chance 
to use it for anything real. never really seen an expert using it 
either...

virtual windows - rendering graphics into an image means that a stream 
of images can be sent over a network to another user in a "terminal 
services"-like session.

well, in a way they do. there is a ctrl, alt and cmd key. on PC keyboards, 
the ctrl key handles things that normally is assigned to the cmd 
key and the ctrl key. this makes it a bit confusing to copy (ctrl-c) 
things from a terminal on a PC keyboard, whereas the mac keyboard 
uses cmd-C to copy. in rebol this means that the ctrl functionality 
in windows should be mapped to cmd on the mac, but if this was to 
be done right, we'd need a /cmd refinement as well.

A console-mode core build could even be used on Android directly 
from the terminal.
