Re: xterm color support

[Robin]

Oddly enough I was just looking into ANSI escapes for the mud I was 
banging on about in another thread and came to the conclusion "Why use 
a module when you can just pepper your text with ANSI escape codes?" :

ANSI Color Codes in brief:

          0        to restore default color
          1        for brighter colors
          4        for underlined text
          5        for flashing text
         30        for black foreground
         31        for red foreground
         32        for green foreground
         33        for yellow (or brown) foreground
         34        for blue foreground
         35        for purple foreground
         36        for cyan foreground
         37        for white (or gray) foreground
         40        for black background
         41        for red background
         42        for green background
         43        for yellow (or brown) background
         44        for blue background
         45        for purple background
         46        for cyan background
         47        for white (or gray) background
you use the above codes together with an escape sequence like this 
(replace the '#' with the colour code of your choice) :

\e[#m

Once you've used an escape all subsequent text will be affected until 
you use the reset escape

\e[0m

so if I want to format a part of a line of text, instead of:

print "This boring old line of text was supposed to have red text\n";

do this:

print "This new improved, brighter, more interesting line of text has 
\e[31mred text\e[0m\n" ;

or maybe even liberally chucking in a bit of '\e[5m' to really endear 
you to users, if you want to use two escapes on the same piece of text 
use one of these ';' :

\e[#;#m

print "This \e[5m new improved \e[0m, \e[5m brighter \e[0m, more 
\e[5minteresting \e[0m line of text has \e[31;5mflashing red 
text\e[0m\n" ;

A fuller listing of ANSI ecapes can be found here:

Note the implmentation of ANSI varies wildly, so expect colour and 
(possibly) formatting but not consistency. Especially from Mircrosoft 
:).

Hi everyone,
I have a question about the following script:
use Term::ANSIColor;
print color("red on_white"), "Danger, Will Robinson!\n";
print color("red on_white"), "Danger, Will Robinson!\n";
print color("red on_white"), "Danger, Will Robinson!\n";
print color("reset");
For some reason, the 1st line has only Red Text on a White Background, 
while the last 2 lines have only Red Text.
There doesn't seem to be any problems with lynx and colored text.
I am using v1.07 of  Term::ANSIColor.
Has anybody experienced the same problem or is there a problem with my 
script?
Thanks in advance.
