Re^5: 'rgb_palette' - Term::ANSIColor Helper -- errors on strawberry

It's down to the version of Term::ANSIColor.

I had Strawberry 5.30.0.1's default Term::ANSIColor v4.06, and it gave me the same error Discipulus saw. I tried

@echo =================== 8 v 16
perl -E "use Term::ANSIColor; say my $x=colored('red text', 'red on_wh
+ite'); use Data::Dump; dd $x"
perl -E "use Term::ANSIColor; say my $x=colored('red text', 'bright_re
+d on_white'); use Data::Dump; dd $x"
perl -E "use Term::ANSIColor; use Data::Dump; my $x = colored('black o
+n white', 'black on_white'); say $x; dd $x"
@echo =================== 256 vs 8 or 16
perl -E "use Term::ANSIColor; use Data::Dump; my $x = colored('black o
+n white', 'rgb000 on_white'); say $x; dd $x"
@echo =================== [id://11146167]
perl -E "use Term::ANSIColor; use Data::Dump; my $x = colored('black o
+n white', 'r0g0b0 on_white'); say $x; dd $x"
perl -E "say qq(\e[38;5;16;47mblack on white\e[0m)"
perl -E "say qq(\e[38;2;0;0;0;47mblack on white\e[0m)"
perl -E "say qq(\e[38;2;255;0;0;47mred on white\e[0m)"
perl -E "say qq(\e[38;2;0;127;0;47mgreen on white\e[0m)"
perl -E "say qq(\e[38;2;0;0;255;47mblue on white\e[0m)"
perl -E "say qq(\e[38;2;191;127;191;47mpurple on white\e[0m)"
perl -E "use Term::ANSIColor; use Config; say for $Term::ANSIColor::VE
+RSION, $], $Config{myuname};"

... And everything but the r0g0b0 worked†; the r0g0b0 gave Invalid attribute name r0g0b0 at -e line 1.

I then realized that since kcott was using v5.36, there was probably a newer Term::ANSIColor , so then I ran cpanm Term::ANSIColor, which installed 5.01. When I ran my same batch script with the updated module, it worked without the error.

So Discipulus, you need to update Term::ANSIColor. Per their change list, rNNNgNNNbNNN notation was added in 5.00.

(To get the colors to work, I did use the VirtualTerminalLevel = 1 that the AM recommended)

edit: †: with full 24 bit color working fine for the red, green, blue, and purple, using manual escape sequences.

Hello pryrt and kcott, yes the upgrade did the trick: `cpan> upgrade Term::ANSIColor Package namespace installed latest in CPAN file Term::ANSIColor 4.06 5.01 RRA/Term-ANSIColor-5.01 +.tar.gz` [download] L* There are no rules, there are no thumbs..

G'day pryrt, Thanks for your research and discovery. Yes, I am using Perl v5.36 and Term::ANSIColor v5.01 came with that (it's a dual-life module). The first stable version of Perl with Term::ANSIColor v5.00 (or later) is Perl v5.32.0 (with Term::ANSIColor v5.01): https://perldoc.perl.org/5.32.0/Term::ANSIColor. The most recent version of Perl offered by "Strawberry Perl" is v5.32.1.1. So, presumably, updating Strawberry Perl would be another way to get the required version of Term::ANSIColor.
