Subject description: Make it support 256 color terminals.		  
--------------------------------------------------------------
There is a "bug" on screen in general, about the termcap
entries on terminal with 256 colors (`$TERM too long`).
I checked the source code and the string length '20' is hard
coded somehow, so it cannot support 'rxvt-unicode-256color'
(just 21 chars Twisted Evil ).
--------------------------------------------------------------
On one system, I tried to hack the termcaps (copied via
`infocmp` the old rxvt-unicode-256color' into a custom
'urxvt-256color', edit the /etc/termcap file, the terminfo
files for screen...) but not success.
Then I made the test of change those '20' values and worked
(supports my custom $TERM with 256 colors, non custom ones
too), no problems on color part, although it crashed several
times... Rolling Eyes
Luckily, found a patch somewhere that does the same I tried,
but better... As far as I know, it works fine.

TO COMPILE

Arrow Here will find the patched sources (vpatch + long $TERM names patch applied and already on the source).
Arrow Here and here will find both patches. To apply, extract source code, `cd` into that dir and run:
Code:
patch -p1 < longTerm_name_00.diff

(may get some warnings with that one).
Arrow To compile it, I'd use:
Code:
./configure --prefix=/usr --with-sys-screenrc=/etc/screenrc --with-pty-mode=0620 --with-pty-group=5 --disable-socket-dir --enable-locale --enable-colors256 --enable-rxvt_osc && make

but on some Puppies, u/rxvt may lack of OSC support.

Then `make install` or, if want to build pet package, install it on a new directory
Code:
make --DESTDIR=/root/screen-4.0.3 install

and `dir2pet` it.

SCREEN 256 color test

If all is working and run this code from a screen session:
Code:
( x=`tput op` y=`printf %$((${COLUMNS}-6))s`;for i in {0..256};do o=00$i;echo -e ${o:${#o}-3:3} `tput setaf $i;tput setab $i`${y// /=}$x;done; )

should be able of see gradients between "xcolors" (requires tput).

This perl script test it (nothing extra required for run it), and this one too (vim isn't neded, just Perl).

To check how many colors your actual terminal support, run:
Code:
tput colors

and to check $TERM, simply:
Code:
echo $TERM


Arrow Added.
If want to see those suppoted colors with numbers:
Code:
perl -E 'say $_,`tput setb $_`," "x(`tput cols`-length("$_")),`tput sgr0` for 0..(`tput colors`-1)'
