I recently installed Ubuntu Linux on one of our machines at work and tried to
install Euphoria today. Ubuntu uses the GNOME terminal as it's default terminal
emulator. However, Euphoria can not run in the GNOME terminal for some reason. It
will run fine in xterm but not in the GNOME terminal. I haven't tried Konsole
(the KDE terminal emulator) nor eterm yet so I don't know if it works with them
or not but from the error message it seems Euphoria requires xterm. This should
either be fixed or a message should be in the documentation about it since xterm
might not be in all Linux distros.
Also, a really good feature to add would be a true Linux/BSD console version of
the interpreter, one that will use STDOUT and not ncurses. People at work often
think my program crashes or doesn't work because their terminal will change when
displaying stuff. The Windows interpreter has exwc so exuc makes just as much
sense.

Ncurses seems to cause alot of problems with screen and file output. When escape
characters are used, they often emit strange characters instead of functioning
like their suppost to.
Ncurses allows the Linux and FreeBSD versions have pixel graphics on many Unix
terminals. The Linux and FreeBSD Language War game are an example of color ASCII
graphics in use.
I'm not sure how Euphoria could do without it and still have working pixel
graphics. Maybe if Robert used the latest version of the Ncurses library, things
would work better?

It may work better (at the expense of breaking compatibility perhaps) but for
many tasks (such as all the stuff I've replaced bash and perl scripting with
Euphoria) it'd be fine to give up pixel graphics just to have "normal" Unix text
output. I would still use the ncurses version but for somethings you just need
vanilla text output.

I just tried running euphoria from gnome-termal 2.2.1 on RedHat 9.0
and it works ok.
Exactly what kind of problem are you having ?
Are you getting any error messages ?
What type of program are you running ?

Interesting. I wouldn't be surprised if it was a Ubuntu thing (you know how tose
Debian-based distros are...)
> Exactly what kind of problem are you having ?
Returns to prompt with an error message. Nothing executed.

Yes, it says something regarding xterm but I can't remember it offhand and do
not have a computer to test it on right now.
> What type of program are you running ?
Just the interpreter: /usr/local/euphoria/bin/exu
It works in xterm but not the GNOME terminal.

Hi
its an environment xterm export thing.
Before running your program, enter
export TERM=linux
or
export TERM=xterm
Other part - pixel graphics with ncurses? Show me an example please!

I'm sure you didn't mean to say "pixel graphics" here.
Otherwise, I think ncurses should be removed as well. People who need ncurses
could still wrap it and call the .so couldn't they?

I'm almost sure that you meant:
export TERM=ansi
Ah, and btw: I've built a debian package of the public domain version of
Euphoria. That is, the non-commercial parts of euphoria. It puts the files in
sane locations instead of in one monolithic directory, and it also gets rid of
the annoyance of having to set TERM and EUDIR every time you want to use it, as I
have added wrappers for exu and ecu that set those environment variables before
executing the real binaries.
This reminded me of actually uploading it too :)
I believe that I am allowed to repackage it, as the license of the full
non-commercial parts seem to be Public Domain.

Hi
No, I didn't 
To see what your terminal or consle is running, type
echo $TERM
ansi as a terminal may not work in some cases - it seems to depend on the
system,
and as far as I can tell there may also be some influence with UTF encoding
(but I haven't looked into it too much)
Note if you're using a program that doesn't write to the console, then it won't
make a hal'peth of difference what your term type is.

This returns 'xterm' on all X terminal emulators on my system, and 'linux' in a
text console.

I tried setting a few different locales, both UTF and ISO. ansi did work in all
cases, It did work in a text console too.

That's right. I didn't know that. I assumed that exu would try to open the
console when it started and close it when it exited, but that doesn't seem to be
the case.

Ah ha! Fixed it! I just had to add export term=ansi (which I did).
The real problem was that editing .bashrc makes no difference when you're
running tcsh....
