=head1 DESCRIPTION |
89
|
|
|
|
|
|
|
|
90
|
|
|
|
|
|
|
Colors are very pretty. |
91
|
|
|
|
|
|
|
|
92
|
|
|
|
|
|
|
This plugin causes certain prints, warns, and errors to be colored. Generally |
93
|
|
|
|
|
|
|
the return value(s) of each line will be colored green (you can override this |
94
|
|
|
|
|
|
|
by setting C<< $_REPL->normal_color >> in your rcfile). Warnings and |
95
|
|
|
|
|
|
|
compile/runtime errors will be colored with C<< $_REPL->error_color >>. This |
96
|
|
|
|
|
|
|
plugin uses L<Term::ANSIColor>, so consult that module for valid colors. The |
97
|
|
|
|
|
|
|
defaults are actually 'green' and 'bold red'. |
