1. Now for some actual euphoria/linux questions...
Hello again everyone.. It's been a while since I have needed aid from
this group (which is a good thing from my viewpoint). I have a few
questions that perhaps
someone out there knows the answer to. As I am sure most of you don't
remember,
I am recoding a mud that I created in Euphoria. I am stuck at a few
points however..
First, How do I go about running the ex file in the background so that I
do not have to be connected to the server machine?
Second, is there any way to stop euphoria from crashing when it hits an
error in a procedure or function? Instead perhaps to have it report the
error to an error file
and exit the routine at that point?
Third, does anyone know how to alter the color of the text that I send
out through the socket connections?
Any help in these areas would be, as always, appreciated!
Paul

Run it on the server and tell the server to allow it some time to run.

Test all your vars to death before using them. This is going to be difficult
to do without a "goto" command to get out of these situations.

Yes, i just wrote an ansi-ascii mirc-mush translator. You must send the
codes for the colors, and the associated opening and closing tags, that the
mush/mud clients you use expect to see. Having done only one mush, and only
for mirc, i can't say what your system needs to do for the actual codes,
other than look up the olde dos screen codes and try those.

Use: nohup exu ladedah.exu arg1 > /dev/null &
"nohup" causes the program run to ignore hangup-signals when you exit
"> /dev/null" prevents the program from suspending in case of tty output
"&" causes it to be run in the background

No, and the subject has been debated heavily here already. PEu supports
"crash routines" which are called before the erred program terminates, but
you cannot recover to the original routine.

kat already pointed out ANSI codes, and that's the way to go.

Well.. umm.. Did I happen to mention that I am slow? :)
I read the link and have seen the ansi tag codes, yet when I try to use them
in
Euphoria it errors with 'unknown escape character' after the initial \ in
codes such as
\[\033[1;30m\]. I am missing the entire point, ain't I?
Any chance for the idiots guide to what I am doing wrong here? :)
(man do I hate to seem this lost...)

You can use two backslashes to represent one. example:
"\[\033[1;30m\]" ==> "\\[\\033[1;30m\\]"
This is of course assuming we are talking about character
strings in Euphoria code.

When the program sees \ ( the escape character ) in a text string,
it looks at the next character following \ and expects it to have a
special meaning, like \n it sees \ then sees the n which means to go
to a new line. If the program sees \ followed by a character that
has no special meaning then you will get an error so to tell the
program that you really want to use the \ then you use \\ and the
the program sees the first \ followed by another \ which has the
special meaning to the program that you want to use the single slash \

>(man do I hate to seem this lost...)
The trick is representing the escape character (ASCII 27 decimal, 033 octal)
Since Euphoria doesn't support strings with octal escape codes, you have to
do it with something like:
27&"[1;30m"
Here's some graphics.e-ish code to print colors using ANSI:
global constant
BLACK = 0,
BLUE = 1,
GREEN = 2,
CYAN = 3,
RED = 4,
MAGENTA = 5,
BROWN = 6,
WHITE = 7,
GRAY = 8,
BRIGHT_BLUE = 9,
BRIGHT_GREEN = 10,
BRIGHT_CYAN = 11,
BRIGHT_RED = 12,
BRIGHT_MAGENTA = 13,
YELLOW = 14,
BRIGHT_WHITE = 15
global procedure clear_screen()
putc(1, 27)
puts(1, "[2J")
end procedure
constant text_color_map = {
"[0;30",
"[0;34",
"[0;32",
"[0;36",
"[0;31",
"[0;35",
"[0;33",
"[0;37",
"[0;1;30",
"[0;1;34",
"[0;1;32",
"[0;1;36",
"[0;1;31",
"[0;1;35",
"[0;1;33",
"[0;1;37",
"[1;7;40",
"[1;7;44",
"[1;7;42",
"[1;7;46",
"[1;7;41",
"[1;7;45",
"[1;7;43",
"[1;7;47"
}
constant bk_color_map = {
";40m",
";44m",
";42m",
";46m",
";41m",
";45m",
";43m",
";47m",
";40m",
";44m",
";42m",
";46m",
";41m",
";45m",
";43m",
";47m",
";30m",
";34m",
";32m",
";36m",
";31m",
";35m",
";33m",
";37m"
}
integer textc, bkc
textc = 16
bkc = 1
global procedure text_color(integer color)
textc = color + 1
putc(1, 27)
if bkc <= 8 or textc > 8 then
puts(1, text_color_map[textc])
puts(1, bk_color_map[bkc])
else
puts(1, text_color_map[textc+16])
puts(1, bk_color_map[bkc+8])
end if
end procedure
global procedure bk_color(integer color)
bkc = color + 1
putc(1, 27)
if bkc <= 8 or textc > 8 then
puts(1, text_color_map[textc])
puts(1, bk_color_map[bkc])
else
puts(1, text_color_map[textc+16])
puts(1, bk_color_map[bkc+8])
end if
end procedure
global procedure position(integer line, integer column)
puts(1, 27)
printf(1, "%d;%df", {line, column})
-- printf(1, "%d;%dH", {line, column})
end procedure

Sooner or later I must get around to building that monument dedicated to you
in the back yard....
Thanks much Pete!
9. Re: Now for some actual euphoria/linux questions...
I knew the others where on the wrong track and obviously have no
experience with ANSI codes. The were attempting to address the Euphoria
error. Good job on the Euphoria error folks but to your dismay the issue
was actually ANSI related not Euphoria.
PS: This wasn't my hurdle to jump. A few of you had correct yet badly
aimed answers. (not being sarcastic here) I greatly appreciate your
attempts at solving the problem of our fellow Euphoria list member.
Failed attempts are much better than no attempt at all. This is the
kind of stuff that make be proud to be a Euphoria list member.
